ArduSimple has announced the availability of a range of GNSS starter kits for anyone in Europe or the United States who is interested in testing or integrating high-precision centimeter accuracy for a service or product proof of concept (PoC).
Building a PoC for increasingly common applications such as autonomous vehicles, where high levels of positioning accuracy are required, is often a complex process. Finding compatible antennas that are tuned correctly, CPUs, modems that connect to GSM, sourcing a global SIM, finding a suitable real-time kinematic correction engine that works in multiple regions, and mounting it all on a board is a lengthy and costly process, according to ArduSimple.
To solve this issue, ArduSimple pulled together the components and services required into a range of starter kits that work out of the box. The simpleSSR Starter Kit works anywhere in Europe and the United States that has a 4G signal.
“Bringing together the components, high-precision accuracy and connectivity in Europe and the United States in one simple out-of-the-box solution will significantly speed up the process of PoC projects,” said Marc Castillo, senior consultant at ArduSimple. “We’ve reduced the complexity, enabling engineers to focus on the feasibility of their projects.”
The kit includes:
1 simpleRTK2B-F9P V3 board
1 u-blox ANN-MB-00 Antenna for GNSS Dual Band with cable (IP67)
4G radio module with NTRIP client including RTK-SSR engine (XBee socket compatible)

Honeywell has launched a new series of miniature inertial measurement units (IMUs) ruggedized to offer high accuracy along with the durability to survive high-shock environments.
Roughly the size of a water-bottle cap, the new HG1125 and HG1126 IMUs are low cost and serve both commercial and military applications.
The new family of IMUs can survive shocks up to 40,000 G-force, making it one of Honeywell’s toughest IMU products to date. The HG1125 and HG1126 can be used for a variety of defense and commercial applications such as tactical military needs, drilling, unmanned aerial vehicles or navigation systems for general aviation aircraft.
“Low-cost, ultra-rugged IMUs are in high demand across a variety of market segments where customers need high-performance navigation, but they’re limited by size or cost constraints,” said Matt Picchetti, vice president and general manager, Navigation & Sensors, Honeywell Aerospace. “Our new HG1125 and HG1126 products meet all of these requirements, making them an ideal solution for customers operating in a wide variety of high-shock environments, including everything from military tactical operations to industrial applications such as drilling.”
An IMU uses gyroscopes, accelerometers and electronics to give precise rotation and acceleration data. This enables a vehicle system to calculate where it is, in what direction it is going, and at what speed, even when GPS signals are not available.
The HG1125 and HG1126 use sensors based on micro-electromechanical systems (MEMS) technology to precisely measure motion. They are the newest IMUs from Honeywell’s tactical IMU production facility, which delivers nearly 100,000 IMUs each year to customers across a wide range of segments.
The first deliveries of these new products are set to begin in June.
Honeywell’s lineage in navigation dates to the 1920s, and it has long been a pioneer in MEMS-based IMUs. Honeywell has developed and manufactured high-performance navigation solutions found on many aircraft and other vehicles worldwide.
What improvements will GPS III bring to high -precision surveying? When? Will these improvements require any changes in equipment and/or processes?
Tony Agresta, Nearmap
“The biggest impact of GPS III to high precision surveying will be a full constellation of L5 satellites. Triple frequency will bring faster convergence times and better accuracy in more difficult conditions. GPS III will better align with Galileo and BeiDou with L1C which means better availability in restricted sky conditions. Users will want to have equipment capable of supporting these new signals, in antenna and receiver HW as well as the signal processing done on board.” Tony Agresta

Jean-Marie Sleewaegen
“Of all the improvements brought by GPS III, the new L1C signal will probably have the biggest impact on high-precision surveying. Compared to L1 C/A, L1C brings better reception in difficult environments, improved availability thanks to the “pilot” component, enhanced resilience to jamming attacks, and better interoperability with Galileo, BeiDou and QZSS. Many receivers do support L1C already, but the benefits will become more tangible as the GPS III constellation grows.” Jean-Marie Sleewaegen

Komatsu Australia and Skycatch Inc. are partnering to boost the efficiency of construction, mining and quarry sites across Oceana with the High Precision Package.
The High Precision Package is also known as Komatsu’s Everyday Drone Solution, a key component to the Smart Construction workflow.
The Everyday Drone contains the Explore1 high-precision UAV, the Edge1 integrated GNSS base station and edge compute module, and the Viewer, an online data visualization and analysis tool, packaged into a commercial-grade kit.

The Everyday Drone allows a user to experience time to data without needing ground control points (GCP), and the ability to seamlessly integrate precision aerial data into their Smart Construction Workflow.
In common construction workflows, the time to data using traditional surveying methods could take weeks until project stakeholders can view or analyze their job site data. With the Edge1, customers are able to leverage a seamless GCP free workflow that consistently delivers sub 50-mm accurate data, in arbitrary or local coordinate systems within 30 minutes, saving countless hours and labor costs.
“We are now using the Everyday Drone at the start of projects to collect whole site information for pre-tender and bidding capability, comparing against 3D design surface to provide fleet and project managers real, accurate information viewed in the Smart Construction Application,” said Aaron Marsh, national technology solution expert manager, Smart Centre, Komatsu Australia. “This allows them to work out their cut and fill volumes with accuracy from the beginning, and enables the project tender team to select the right machines for the project optimising fleet recommendation and empowering the team to make the right, data-based decisions from the start.”
“Skycatch is proud to offer a better way of accessing precision data on-site. With traditional methods, the solutions are piecemeal, cumbersome, and time-consuming,” said Christian Sanz, Skycatch founder and CEO. “Now, customers are able to make informed decisions about changes to what was planned and what is actually happening on site in near real-time, ultimately providing greater productivity, increased profit and reducing project risk from beginning to end,”
Customers tested the receptiveness of the Everyday Drone Solution, said James Mackenzie, national remote support manager at Komatsu Australia. They first tested in civil construction, and then quickly expanded into quarry sites. Mackenzie was able to survey six quarries in five days for different customers, post-processed in the cloud, receiving the data back the next day.
“Compared to a traditional survey, this is 100% more productive and efficient,” Mackenzie said. “By using the Everyday Drone, customers are no longer putting themselves in harm’s way, surveying around heavy machinery or climbing up unstable stockpiles at risk of twisting an ankle.”
He also noted that customers appreciated the fast turn-around time, the ease of use, and the ruggedness of the products.
“Skycatch’s ability to provide near real-time data throughout the entire project is vital, and being able to deliver that to the customer, supervisor and give project teams the ability to make decisions throughout the project easily with usable, accurate data is key to the success of the project as a whole, not just in siloed environments is priceless,” Marsh said.

Inertial Sense has released a new micro-sized inertial navigation system (INS) with precise real-time-kinematic (RTK)-level accuracy. The company says the new solution paves the way for high accuracy in mass-market consumer applications.
The new micro INS with RTK solution offers an accuracy of 2-3 centimeters using GPS positioning in combination with inertial sensors (including on-board sensor fusion).
Inertial Sense designs and manufactures precision INS+RTK GPS sensors that deliver fast, accurate and reliable altitude, velocity and position for a wide range of autonomous vehicle applications, the company said.
The new micro INS with RTK provides a high degree of precision for orientation and GPS in a tiny package. Standard INS/GPS sensors offer accuracy in the range of 1.5 to 2 meters. Inertial Sense’s micro INS with RTK offers accuracy of 2-3 centimeters.

“The incredibly small size of our new micro INS with RTK sensor, in combination with its extremely affordable price point, will make this type of highly sophisticated technology accessible for general consumer applications for the very first time,” said Walt Johnson, founder and CTO, Inertial Sense. “We are offering RTK at a size, accuracy and price point that the market has never seen before.”
By optimizing the manufacturing processes for high volume applications, the micro INS with RTK sensor is as small and lightweight as a dime, and is available at a low price point.
Sensor fusion. Sensor data from MEMs gyros, accelerometers, magnetometers, barometric pressure and u-blox GPS/GNSS are fused to provide optimal position estimation. Data out includes angular rate, linear acceleration, magnetic field, barometric altitude and GPS time.
The miniature module provides orientation, velocity and position. Base station corrections data can be applied to achieve centimeter-level precision.
Autonomous vehicles. The sensor will enable the navigation of all types of autonomous vehicles with a very high degree of precision, Inertial Sense said.
Inertial Sense patented modules are currently being sold worldwide at volume for a broad variety of applications including:
Aerial surveys: UAV Payloads for 3D mapping, photogrammetry, orthomosaics
Gimbal stabilization and antenna pointing
3D motion capture and personnel tracking
Evaluation kits. Inertial Sense has bundled evaluation kits it says are simple to use and contain everything needed to begin logging RTK-accurate data. The evaluation boards can be utilized in both rover and base station configurations and include 900-mhz radios with onboard logging capabilities.
Septentrio has launched the Mosaic high-precision GNSS receiver module.
Despite its compact size (31 x 31 x 4 millimeters, 1.29 x 1.29 x 0.15 inches), the Mosaic module supports more than 30 signals from all six GNSS constellations, L-band and various satellite-based augmentation systems, the company said.
As a multi-band module tracking all GNSS satellites in view, it is also designed to support future GNSS signals.
It also supports correction services, and uses real-time kinematic (RTK) technology, together with Septentrio’s algorithms, to guarantee maximum accuracy and availability. The surface-mount design of Mosaic is optimized for automated assembly and ease of integration, with a full library of well-documented and flexible interfaces.
“Our new Mosaic module represents the best-in-class option for reliable and scalable position accuracy, with integrity,” said Chris Lowet, product manager at Septentrio. According to Lowet, it provides RTK positioning with a power consumption of 0.6-1 W, and requires no or minimal additional components for the design-in. “These characteristics make it an ideal positioning cornerstone for a variety of mass market UAV, autonomous and robotics applications,” Lowet said.

Robustness to interference. Due to the natural weaknesses of distant GNSS signals and a crowded radio-frequency spectrum, GNSS-based services are vulnerable to unintentional radio-frequency interference (RFI). They are also vulnerable to intentional RFI, attacks intended to disrupt receivers by means of counterfeit GNSS-like signals (known as spoofing), and to intentional transmission of RF energy to mask GNSS signals with noise (known as jamming).
To defend against these threats, Mosaic features Septentrio’s AIM+ technology. AIM+ can suppress the widest variety of interferers, from simple continuous narrowband signals to complex wideband and pulsed jammers, the company added. In addition, the integrated spectrum analyzer allows the RF environment around any Mosaic module to be viewed in real time in both time and frequency domains.
Effective interference countermeasures against threats to GNSS signals also require constant knowledge of the changing RF environment. The Mosaic module helps analyze these threats by continuously and automatically monitoring the GNSS frequency spectrum to detect, characterize, log and mitigate interference events when needed.
U-blox, a global provider of positioning and wireless communication technologies, has released the ANN-MB multi‑band active GNSS antennas, tailored specifically to the needs of applications requiring centimeter-level positioning accuracies.

ANN-MB offers product designers an easy-to-implement and reliable multi-band antenna solution, u-blox said. It is designed for small- to medium-size customers with little experience with GNSS antennas who would like to accelerate their time to market.
The ANN-MB antenna series builds on u‑blox’s two decades’ worth of experience with high-performance antennas for GNSS receivers. Developed in conjunction with the recently announced u‑blox F9 multi-band high precision positioning platform, ANN‑MB receives signals on the L1 and L2/L5 bands of all four global navigation satellite constellations (GPS, GLONASS, Galileo and BeiDou).
The antenna features versatile mounting and connector options (SMA, SMB, MCX) and supports an extended temperature range (up to 105 degrees Celsius), making it suitable for applications subject to extreme temperatures, the company added.
“With the u‑blox F9 platform, we took a major step in bringing down the cost of ownership of high-precision GNSS technology, such as our recently announced u‑blox ZED‑F9P module,” said JunJun Lu, senior engineer of product management, Product Center Positioning at u‑blox. “The ANN-MB multi-band antenna series takes this effort one step further, paving the way for new high precision positioning applications in the consumer and industrial markets.”
A limited number of ANN-MB-00 (SMA) prototypes are available now, with production of the ANN-MB series planned for December.
GNSS antenna maker Tallysman has introduced the TW7875 magnetic mount GNSS antenna, which is designed for precision dual-frequency positioning. It is capable of receiving GPS L1/L5, GLONASS G1, BeiDou B1, Galileo E1/E5a and NavIC L5.
The TW7875 employs Tallysman’s Accutenna technology, which provides superior multipath signal rejection due to its low axial ratio across the full bandwidth, the company said.
The antenna also provides a linear phase response and tight phase center variation at a new economical price point, according to the company, which said it provides performance comparable to higher priced dual-band GNSS antenna.
It is designed for precision agriculture, autonomous vehicles and other applications where precision matters.
The TW7875 is housed in a magnetic mount IP67 rated housing. It can also be ordered without the magnet since it can also be mounted by screws or double-sided adhesive tape.
Model TW3875 is the embedded antenna version of the TW7875. It is available with a wide selection of connectors and custom cable lengths, and can be custom tuned by Tallysman to ensure optimum performance within the customer’s enclosure.
