Trimble has introduced the Trimble BD935-INS module that features precision GNSS with an integrated 3-D Micro-Electro-Mechanical Systems (MEMS) inertial sensor package. As part of Trimble’s GNSS OEM portfolio, the new compact module augments real-time precise positioning with 3-D orientation.
The BD935-INS module’s simple connectivity and configuration capabilities allow system integrators and OEMs to easily add GNSS and attitude to specialized or custom hardware solutions, Trimble said in a news release.
“The OEM and system integrator communities demand high performance, reliability and support for their positioning solutions,” said Dale Hermann, general manager of Trimble’s Integrated Technologies Division. “The Trimble BD935-INS delivers the latest GNSS and inertial technology in an easy-to-integrate form factor for demanding conditions and applications such as lightweight robotic or unmanned vehicles. With the BD935-INS module, customers are purchasing a robust navigation solution, extending performance beyond that of a GNSS receiver only.”
Taking advantage of Trimble’s expertise in both GNSS and inertial technologies, the Trimble BD935-INS module has been designed for applications requiring both RTK and orientation in a compact package. By integrating inertial sensors onto the GNSS module, users can experience more robust performance in a variety of challenging environments, Trimble said.
The BD935-INS features triple frequency for both GPS and GLONASS constellations, as well as dual frequency for BeiDou and Galileo. The module delivers fast and reliable RTK initialization for 1–2 centimeter positioning. For applications that do not require centimeter accuracy, the BD935-INS integrated GNSS-inertial engine delivers high-accuracy GNSS and DGNSS positions in challenging environments such as urban canyons, tunnels, heavy canopy or other GNSS-denied environments, the company said.
Trimble also announced the new BX935-INS, which is an environmentally rugged enclosure for OEM or system-level integration. The BX935-INS houses the Trimble BD935-INS module for easy installation and immediate access to high-rate position and attitude data for a variety of applications.
The Trimble BD935-INS and BX935-INS is expected to be available in the third quarter of 2015 through Trimble’s Integrated Technologies Precision GNSS sales channel.

SBG Systems, a manufacturer of inertial navigation systems (INS), has selected the Septentrio AsteRx4 OEM GNSS receiver to equip its Apogee product line. The announcement was made during Ocean Business 2015, held April 14-16 in Southampton, England.
SBG Systems’ Apogee-D
“We are delighted that SBG Systems — a respected specialist in designing INS/GNSS — endorses our newly released GNSS receiver for its performance,” said, Laurent Le Thuaut, business development manager at Septentrio. “The SBG products are recognized amongst the preferred choice for accurate MEMS-based INS and we are extremely proud that our technology is included in their top of the line.”
Apogee is a new product line of high-accuracy inertial navigation systems based on robust and cost-effective MEMS technology. The INS/GNSS solution combines the latest generation of MEMS sensors and the OEM version of the AsteRx4, a newly introduced high-precision GNSS receiver from Septentrio. The Apogee series is especially suited for applications such as hydrography, mobile mapping and aerial survey where survey-grade positioning measurements are required.
AsteRx4 OEM
The AsteRx4 OEM is a multi-frequency and multi-constellation dual antenna receiver that incorporates the latest innovative GNSS tracking and positioning algorithms from Septentrio. The AsteRx4 is scalable to one centimeter and integrates the entire suite of GNSS+ algorithms proposed by Septentrio to maintain tracking during heavy vibration of machines. This assures position accuracy under difficult ionosphere conditions and mitigates or rejects intentional or unintentional interference with GNSS signals.
“The compact design and the practical and well-designed interface of the AsteRx4 allowed a seamless and an easy integration into our solutions” said Raphaël Siryani, chief marketing & sales officer of SBG Systems. “The AsteRx4 largely contributes to the robust and accurate heading as well as the reduced power consumption of the INS/GNSS Apogee products.”
Both the AsteRx4 OEM receiver and the Apogee INS/GNSS are on display at booth No. W40 (Septentrio) and booth E5c (SBG Systems) at Ocean Business.
InvenSense Inc. is making available its InvenSense Positioning Library (IPL) software, designed to provide sensor-assisted positioning in places where GNSS alone cannot provide desired accuracy. Invensense is a provider of intelligent sensor system on chip for motion and sound in consumer electronic devices.
InvenSense made the announcement at Mobile World Congress, taking place in Barcelona, Spain March 2-5.
The IPL incorporates advancements in sensor-assisted positioning algorithms that allow use of inertial sensors to improve GNSS positioning in urban areas where satellite signals are either blocked or distorted by multipath, enabling continuous location availability while driving in underground parking lots, tunnels, or walking in urban canyons. The IPL enables continuous and accurate position, velocity and orientation in challenging operating environments.
These sensor-assisted positioning algorithms have been designed to operate under normal pedestrian and driving use without restrictions on the device orientation. Supported pedestrian use includes handheld, hand swinging, in pocket, call mode and belt holster. The algorithms also allow any use within the vehicle, such as in cradle, cup holder or simply left on a seat. The software was designed in a way to maximize accuracy and minimize constraints on the user.
The IPL is designed to operate with an IMU and GNSS receiver as minimum hardware. Integration with a magnetometer, barometer, and vehicle speed sensor is also available, which provides additional heading integrity as well as height and velocity accuracy for sensor-assisted positioning.
IPL is designed for smartphones using Android, iOS, Windows and general Linux operating systems and has already started shipping commercially. The underlying navigation technology comes from years of development at Trusted Positioning Inc., which was acquired by InvenSense this past summer.
“With more consumers using their smartphones for turn-by-turn navigation on foot or in vehicle, one of the most frustrating user experience issues is losing your GPS (GNSS) signal in an unfamiliar location or being re-routed erroneously due to multipath errors,” said Ali Foughi, vice president of Marketing and Business Development at InvenSense. “With IPL technology, high-accuracy location guidance is always available and provides smartphone OEMs with a differentiated user experience and consumers with a more reliable navigation solution.”
The InvenSense Positioning Library is available immediately.
InvenSense is exhibiting in booth #D61 in Hall 7 at Mobile World Congress.
SBG Systems has released the Apogee Series, its most accurate inertial navigation systems based on robust and cost-effective MEMS technology. The INS/GNSS integrates the latest generation of MEMS sensors and a tri-frequency GNSS receiver. Apogee achieves 0.008° in roll and pitch in real-time and 0.005° in post-processing. With two antennas, it delivers a robust and accurate heading.
Four models compose the Apogee line.
The Apogee-A provides only orientation data.
The Apogee-N additionally embeds a GNSS receiver; it is a compact solution with one antenna for land and aerial applications.
The Apogee-D embeds a dual-antenna GNSS receiver for accurate heading under low dynamics conditions.
The Apogee-E delivers navigation data when connected to an external GNSS receiver or to the SplitBox with integrated GNSS.
Mobile Mapping. Apogee can be precisely synchronized with LiDAR equipment because of a UTC time-stamping accurate to 1 microsecond. This integrated INS/GNSS provides optimal position in multipath environment or during GNSS outages, thanks to a tight GNSS integration and the continuous fusion of inertial and odometer data. To get the required positioning accuracy, Apogee supports RTK and Precise Point Positioning services (Omnistar, Terrastar, and more).
Aerial Mapping and Remote Sensing. With very low noise gyroscopes, low latency, and high resistance to vibrations, the Apogee allows aerial surveys by plane or helicopter. It provides real-time orientation and position data with direct fusion of inertial and GNSS information. Compact, lightweight and low power, the Apogee is easy to install, and has an embedded web interface for configuration.
Post-processing. Orientation and position data can be recorded in the Apogee data logger. At the office, the user imports data in the post-processing software. This tool gives access to several RTK networks and reference station offline data (such as VRS and CORS.) Additionally, it enhances orientation and position accuracy by a complete “backward/forward” calculation.
“SBG Systems manufactures inertial systems from the concept to the production. The Apogee benefits from our high level of expertise in integrated design, IMU calibration, testing, and filtering,” said Alexis Guinamard, CTO of SBG Systems.
All models are available for order. Below is a promotional video with more information.

Another year has gone by, with another year of further improvements in navigation performance of micro-electro-mechnical systems (MEMS) inertial products. SBG Systems in France is now fielding a new generation of MEMS inertial products for much higher accuracy applications.
SBG Systems is based in Rueil-Malmaison, less than eight miles west of the center of Paris. Founded in 2007, SBG has developed a number of innovative MEMS inertial products over the last seven years, along with a respected reputation in the navigation industry, and by 2014 the company was recognized as the 26th fastest growing company in France.
The roots of the company began to form at the end of 2004, when a group of ECE School of Engineering students in Paris put a team together for a new UAV competition. The goal was to build a UAV of less than 1 kg, capable of flying autonomously indoors — at the time, a significant technical challenge. In 2004, miniature INS was not commercially available, so the team decided to build one, as well as other electronic parts such as the autopilot. The competition ran out of money, but the design was a success and led to a working UAV. The INS was by far the most advanced part of the project.
The students went back to their studies and took internships at UAV companies and ONERA (French aeronautics, space and defense research labs), but they still believed in the need for low-cost navigation solutions for the emerging civilian UAV market.
So, in 2007, three of the students — Raphaël Siryani, Thibault Bonnevie and Alexis Guinamard, S, B and G — formed SBG Systems with the goal of providing affordable, highly accurate MEMS inertial navigation systems for UAVs.
SBG quickly received its first Innovation Award from the French Research Ministry, and with this funding launched the IG-500 series of MEMS AHRS and INS in December 2008.
The company has since grown into a worldwide player with a strong product innovation focus. UAVs are still an important part of revenue, but the company has diversified into:
Aerospace and defense applications (UAVs, gimbaled cameras, antenna tracking, etc.)
Marine and offshore activities (ROV/AUVs, buoys, etc.)
Survey (hydrography, mobile mapping, aerial LiDAR, etc.)
SBG Systems has a small staff of mostly development and sales engineers — graduate students and experts. SBG has recruited navigation experts and some sales people from key players in the inertial business. Most (95%) have at least a master’s degree in engineering — R&D has 45% of the staff, and 40% are in sales, marketing and technical support. Production has been extremely automated and requires very few staff for in-house system assembly, calibration and final acceptance test. They do expect to double in size over the next two to three years.
The company is owned by the three founders, who still lead operations. SBG grew 1,304% over the last five years, and last year was ranked the 26th fastest growing company in France on the Deloitte Fast50. Today, SBG Systems has fielded more than 4,000 attitude and heading reference systems (AHRS) and INS (mostly INS), with almost a third of those delivered last year. The company forecasts growth for the next five years to be at this same phenomenal rate! SBG Systems currently offers a line of MEMS inertial sensors that include AHRS, inertial measurement units (IMU), and INS with embedded GPS (INS/GPS).
Ellipse-D dual-antenna mini INS/GNSS.
Not only have MEMS sensors improved in performance, but SBG has also developed advanced calibration capabilities that allow it to reach high-precision performance approaching high-end ring laser gyro accuracies in much smaller, less expensive packages. SBG owns an extensive set of temperature chambers combined with rotary tables and vibrating tables. Each SBG system gets to stay two to five days inside these calibration tools. But the “secret sauce” is in a state-of-the-art SBG developed calibration algorithm…
SBG buys MEMS gyros and accelerometers from MEMS manufacturers such as Colibrys, Analogue Devices and Silicon Sensing and builds complete inertial systems. The team embeds different GNSS receivers, depending on the product line and intended application — from miniature automotive-grade chipsets from u-blox to the very best from the key survey-grade players such as Septentrio, NovAtel and Trimble. Some customers may already have their own GNSS receiver, so SBG has developed and tuned their systems to work with any of these big manufacturers. The antenna employed depends on the receiver being used — from Tallysman Wireless and Antcom to Trimble, Septentrio or NovAtel — a very diversified range of antennas.
Ellipse-E.
SBG announced the Ellipse-D dual-antenna mini INS/GNSS earlier this month. The Ellipse-D is a miniature INS with an embedded dual-antenna survey-grade GNSS receiver for high-accuracy orientation and positioning.
Independent hydrographic testing in October 2014 of earlier model designs has already shown accuracy improvements, and the latest D version promises even better performance. The products tested were:
Ekinox-D
Ellipse-E, miniature inertial navigation system connected to a Hemisphere VS330 GNSS with two antennas.
Ekinox-D, inertial navigation system integrating a dual-frequency GNSS receiver with two antennas.
The test was a typical marine survey, with each leg about 550 meters long. Attitude performance was compared to a fiber-optic gyro compass reference system with much higher roll and pitch accuracy than the two SBG products under test.
Ellipse-E roll and pitch accuracy is better than the specs. The use of an RTK GNSS receiver additionally improves the sensor’s performance. The Ekinox-D also has good results — around 0.03° in both roll and pitch. SBG claims that low-noise gyroscopes and advanced algorithms are the basis for this performance.
The SBG list of 250 customers in 30 countries includes some impressive names, many outside Europe, and the company claims to have nearly 4,000 inertial sensors in the field. So this is not a prototype shop, but more a fully equipped production facility. SBG has opened an office in Chicago to address the North American market.
So, what are people doing with these devices? There are a number of applications in aerospace, land, marine and sub-sea.
In the aerospace industry, SBG sensors are used for UAV navigation and flight analysis — they could eventually be incorporated in certified avionics. They are also used for antenna tracking, camera stabilization and more demanding applications such as LiDAR orientation and data georeferencing.
An Ekinox-N INS with embedded GNSS receiver was installed for the tests in a single-engine general aviation aircraft flying out of Magdeburg, Germany. A typical airborne survey-type flight was flown under mixed weather conditions with some turbulence, and roll, pitch, and altitude data was collected for real-time analysis and was also post-processed. A high-grade FOG-based AHRS was used as reference unit — with very high accuracy gyroscopes.
The flight pattern was typical of survey applications, with parallel straight lines of about 8.5 km. Altitude was 600 m and cruise speed was about 200 km/h.
Roll
Pitch
RMS Error Real Time (max)
0.043° (0.16)
0.043° (0.16)
RMS Error Post Processing (max)
0.017° (0.19)
0.025° (0.20)
Real-time accuracy remained below 0.05° RMS for roll and pitch. Post-processed output had a lower RMS error and a better stability over the whole flight. Only one GPS antenna was used in this test with Ekinox-N; nevertheless, heading reached an estimated accuracy of 0.06° when post-processed. The Ekinox-D model provides more accurate heading thanks to its integrated dual-antenna and GNSS receiver.
The Ekinox-N has been integrated on a UAV by Headwall in the U.S. for remote-sensing applications.
Headwall is a leading designer and manufacturer of high-performance hyperspectral imaging sensors for harsh environments. As a pioneer for remote-sensing applications, Headwall is the first to market a fully integrated remote-sensing solution combining hyperspectral and LiDAR sensors on a small UAV. This “total solution” approach has been welcomed by the remote-sensing market because it quickens time to deployment, decreases implementation costs, and enables operations in harsh environments.
The multi-rotor UAV carries Headwall’s lightweight Micro-Hyperspec VNIR hyperspectral sensor and a Velodyne LiDAR unit. The LiDAR collects a point cloud that reflects the field’s topographic relief, and the hyperspectral sensor delivers a picture showing spectral signatures of every object within the field of view. The SBG inertial navigation system has an embedded GPS and is used to provide positioning and orientation data. Weight is a key factor — Ekinox-N weighs only 500 grams, even though it integrates a survey-grade L1/L2 GNSS sensor to provide accurate positioning and precision roll, pitch, and heading data.
Mounted on the UAV, the Ekinox-N provides LiDAR and the hyperspectral camera with orientation and position during the whole flight. This and other data is recorded in real time at 200 Hz within the onboard computer. On the ground, the Headwall post-processing Hyperspec software fuses all sensor information. Ekinox-N data allows every scanned point and every pixel to be georeferenced and be tilt compensated to within a centimeter.
SLAM-based Indoor Mapping System by VIAmetris.
For miniature inertial sensors, smaller and lighter applications are possible at less cost. One of these applications includes the SLAM-based Indoor Mapping System by VIAmetris.
Simultaneous localization and mapping (SLAM) is becoming increasingly important to enable efficient indoor mapping. VIAmetris has created a different spin on indoor mapping with the “MID” portable SLAM-based scanner. This handheld system integrates a 2D LiDAR, a camera, an SBG Ellipse-A AHRS, and a tablet PC that shows the map being drawn while the user walks around inside the building. The AHRS also compensates for movement while orienting the generated maps to the north.
While the user walks, the 2D LiDAR scans in a horizontal plane by measuring 43,000 points per second across a 270° field of view. The SLAM technology progressively builds the map in the shape of lines made of points. At the office, the surveyor imports the data into the post-processing software and uses the lines of points to design the map. If there is any doubt about a specific shape — whether it is actually wall or furniture, for example — a photo of the location is available as MID automatically takes contextual pictures every meter, or whenever there is a change of direction, or manually.
The centimeter-level accurate map is then ready to be imported into most CAD software. As the system works without GPS, the generated map is not georeferenced or in a local coordinate reference system. To do so, the user links MID’s points cloud to a known point and all data is automatically referenced. MID is much easier to use than a laser distance meter, a tachometer, or a 3D scanner, and significantly reduces the time required for indoor mapping.
SBG is now working more often in the marine industry, equipping boat, cranes, or instrumented buoys. The company has even developed a specific solution for the hydrographic market. The SBG Ekinox Hydrography Solution integrates Ekinox-U which operates to a depth of 200 meters, and incorporates a SplitBox with a built-in tri-band RTK GNSS receiver and uses Terrastar, OmniSTAR, or Marinestar corrections.
The SBG Ekinox Hydrography Solution.
For subsea operations, positioning is required for ROVs and AUVs that navigate for minutes or sometimes for hours underwater. GPS fixes are only available when the vehicle comes close to the surface. But operators usually try to expend the time they are able to operate close to the seabed. To avoid typical INS drift, different aiding sources are used — the three main ones are acoustic positioning, Doppler velocity loggers (DVLs) and depth sensors.
Acoustic position is far more noisy and unstable than GPS.
DVL is a kind of 2D odometer, providing speed over the seabed.
The INS and the Kalman filter therefore play a key role to provide reference heading and reliable position data.
It’s a major concern when you have a massive ROV working on pipes under an offshore platform. Any mistake can cause severe damage and cost millions.
So SBG is moving along and taking on new, challenging applications with a range of MEMS inertial products that appear to be growing quite rapidly, with ever-improving performance. Once upon a time, we couldn’t stay anywhere within RTK-level performance during GPS outages because of the high drift-rate of MEMS inertial devices. Now, SBG has introduced its latest Ellipse-D dual-antenna mini INS/GNSS spec’ed at 0.1° real time for pitch and roll, with 2-cm RTK position.
The Apogee INS/GNSS.
And just today, SBG Systems has even bigger news with the release of the Apogee series, which is Apogee’s most accurate, robust and cost-effective MEMS technology inertial navigation system. The Apogee INS/GNSS integrates the very latest generation of MEMS sensors along with a triple-frequency GNSS receiver, achieving 0.008° in roll and pitch in real time, and 0.005° in post-processing. With two antennas, it also provides reliable and accurate heading.
Amazing what scientific skill, focused investment and time has done for MEMS inertial technology!
OxTS has released the xNAV550, its new compact and lightweight GNSS-aided inertial navigation system, along with an OEM board set version, the xOEM550.
xNAV550. The xNAV550 is the latest model in the xNAV family and the first to offer a position accuracy of 2 cm, yet remains a compact GNSS-aided inertial navigation system at 425 grams. Suitable for all applications where size and weight as well as performance matter, it is designed for use on UAVs and in other weight-constrained applications.
Featuring dual GNSS receivers and a custom-built inertial measurement unit, the xNAV550 constantly monitors position, orientation and velocity with high accuracy in real-time. Four gigabytes of on-board storage is available, automatically logging data for an added layer of protection. Data can be downloaded from the system and post-processed using OxTS’s advanced software, which is included as standard at no extra cost.
Integrating the xNAV550 with cameras, laser scanners or other sensor arrays is easy using the NMEA outputs, OxTS said, with 1-PPS and event input triggers for synchronization and time stamping. These features and the convenience of the one-box solution ensure that the xNAV550 make it quick and easy to acquire accurate data required for direct georeferencing, the company said.
xOEM550. The xOEM550 is designed for system integrators looking for a high-performance INS to build into a complete scanning and georeferencing system. Weighing 165 grams, it won’t add bulk to a system, and the free and distributable OxTS post-processing software enables system integrators to offer a turnkey solution at a competitive price, the company said.
OxTS will be exhibiting at ILMF 2015 in Denver, Colo., Feb. 23-25. Stop by Booth #30 to take a look at the xNAV and xOEM systems or contact [email protected] for more information.
The xOEMcore, now being offered by Oxford Technical Solutions (OxTS), is an inertial navigation system that can also serve as a framework for other positioning systems.
The xOEMcore is a combined six-axis inertial measurement unit and navigation system with sensor fusion in one compact OEM module. In its base form, the xOEMcore measures and outputs raw accelerations and angular rates with small, high-grade MEMS gyros and accelerometers. With a simple upgrade, the xOEMcore is turned into a full inertial navigation system, able to take aiding data from external sources such as GNSS and blend it in the on-board Kalman filter. It is desgined for integration inside any solution that requires robust, high-performance position and orientation.
xOEMcore provides continuity from one point to the next, so detecting unexpected measurements from other devices is easy, the company said. It has deterministic error growth for accuracy, a high update rate and lowdelay, enabling easier control of vehicles and robots.
As a framework, the xOEMcore can be merged other technologies, such as GNSS and vision positioning. The xOEMcore solves conflicts between the two systems, removing timing mismatches, delays, jumps and inconsistencies.
The xOEMcore is small, light and low power. The inertial sensors have low drift rates — less than 5-meters drift after 60 seconds can be achieved in real-time with only odometer aiding. Heading, roll and pitch can be accurate to 0.05 degrees, exceeding magnetic heading and vertical reference system performance.
Sensors in Motion (SIM) has introduced a MEMS (micro-electro-mechanical) navigation-grade inertial system (INS) that it says could transform the $8 billion/year inertial market with new products by offering price and performance specifications better than those currently available.
The first INS devices have been delivered to the Army CERDEC Night Vision Electronic Sensors Directorate (NVESD).
SIM, a spinout from NASA’s Jet Propulsion Laboratory and California Institute of Technology, is developing a family of high-accuracy MEMS gyroscopes, accelerometers and inertial measurement unit ( IMU) solutions. It says it has perfected unique MEMS structures using volume silicon wafer processing techniques to produce gyroscopes having ARW (angle random walk) less than 0.0035 degree/root-hour and bias instability less than 0.01 degree/hour with extraordinary vibration and temperature immunity, a performance comparable to ring laser (RLG) and fiber optic (FOG) gyros that are 20 times larger and 100 times more expensive.
These features are mandatory for numerous applications where location is not available from GPS or vehicle position accuracy is required including autonomous vehicles, drones, mining asset tracking, dead reckoning, agricultural seed placement, oil and gas directional drilling, self-driving autos, firefighter navigation, optical image stabilization, industrial equipment azimuth, aerospace and defense products and most GPS-denied environments, in addition to new applications.
Current devices would have a vehicle position off as much as 1 foot per second at 45 miles per hour.
“We see this technology opening an additional $2B sensor market needing size, weight, power, cost and performance that does not exist today. “ said David Smukowski, CEO of SIM.
With adequate resources the company says further performance gains are possible, even while shrinking the devices smaller for better economics.
iXBlue unveiled its Marins M series inertial navigation system (INS) at EURONAVAL 2014, held October 27-31 in Paris, France. The series includes the Marins M3, M5 and M7 systems and is designed to address the needs of the world’s most advanced navies for surface-vessel and submarine operations close to shore and in open-sea environments.
Accurate and reliable navigation, including missile alignment, is critical to the success of submarine and surface-vessel missions. The Marins M series raises the bar in performance and scalability by addressing the needs of surface ship navigation under a GPS-denied environment. For submarines, Marins M7 enables three times longer autonomous stealth navigation compared with any available system by offering drifts of less than 1 Nm/72 h.
The Marins M series represents the state of the art in strap-down, fiber-optic gyroscope (FOG) technology, and is combat-ready against GNSS denial, iXBlue said. The military-specification units output position, heading, roll, pitch, depth and velocities, and are perfectly silent. The systems are compatible with a wide range of aiding sensors and can be up and running within minutes.
The extended iXBlue product range, including Quadrans, Octans, Phins and Marins M series systems, now represents even higher scalability of solutions, from attack craft to aircraft carriers and submarines.
More than 30 navies worldwide have selected the iXBlue product range, including previous generations of Marins systems. For example, the UK Royal Navy has adopted advanced iXBlue solutions for its Astute Class submarines.
Oxford Technical Solutions (OxTS) has announced the latest addition to its OEM line of inertial navigation systems, the xOEM500. The OxTS is a high-performance GNSS/INS system embedded on a single compact board set. It offers dual GNSS receivers and a high-grade MEMS IMU (inertial measurement unit) to system integrators in an easy-to-integrate 120-g package.
With attractive prices for volume sales, the xOEM500 is one of the world’s smallest tactical-grade INSs available.

SBG Systems has released the Ellipse Series, a product range of miniature inertial systems replacing the IG-500 Series. For the same budget, customers benefit from higher accuracy, advanced filtering and features of high-end inertial navigation systems, the company said.
The Ellipse Series of miniature inertial systems benefits from a new design, new sensors, new capabilities, and new algorithms. “We have selected state-of-the-art MEMS sensors, especially very low noise gyroscopes that greatly enhance Ellipse performance. We integrated cutting-edge GNSS receiver while keeping a small size,” said Alexis Guinamard, CTO of SBG Systems.
“We are able to upgrade miniature sensors capabilities by injecting some advanced and proven filtering and features inspired from high end inertial navigation systems,” Guinamard said. Besides higher accuracy, SBG Systems added for the same budget an improved FIR and rejection filtering, robust IP68 enclosure, high output rate, RTK corrections, and automatic alignment.
Weighting from 45 grams, Ellipse sensors are flexible. The Ellipse-A model provides 3D orientation and heave. For navigation, users can connect their own GPS receiver with the Ellipse-E, or use an internal receiver by choosing the Ellipse-N model. The larger Ellipse-D integrates a survey-grade L1/L2 GNSS receiver with two antennas for heading and position accuracy.
Ellipse A, N, E models are available for order now. The Ellipse-D model will be available in the first quarter of 2015.
