Tallysman Wireless has added the housed HC885XF and embedded HC885EXF dual-band eXtended Filtering (XF) antennas to its line of helical antennas.
The antennas receive GPS/QZSS L1/L5, GLONASS G1/G3, Galileo E1/ E5a/b, BeiDou B1/B2/B2a and L-band corrections services.
Historically, dual-frequency antennas and receivers commonly supported GPS L1 and L2 and GLONASS G1 and G2. In recent years, GPS, GLONASS, Galileo, BeiDou and NavIC have added GNSS signals in the L5 frequency band (1160-1217 MHz).
As a result, the new dual-frequency GNSS standard has become L1 and L5.
Tallysman’s new HC885XF antenna has been tuned to provide optimal support for the entire L1/G1/E1/B1/L-band correction and L5/G3/E5/B2 bands.
The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539-1559 MHz). New LTE signals in Europe [Band 32 (1452-1496 MHz)] and Japan [Bands 11 and 21 (1476-1511 MHz)] have also affected GNSS signals. Tallyman’s XF models mitigate the effects of these new signals.
The Tallysman HC885XF housed helical antenna weighs ~42 g and is enclosed in a robust, military-grade IP67 plastic enclosure. The antenna base has an integrated SMA connector, a water-proofing O-ring, and three screw holes to enable secure attachment.
Tallysman’s embedded HC885EXF helical antenna weighs ~8 g. It is easily mounted with an optional embedded helical mounting ring, which traps the outer edge of the antenna circuit board to the host circuit board or any flat surface. An MCX connector is installed in the base of the antenna.
Tallysman HC885EXF and HC885XF antennas are suitable for a variety of applications, including lightweight unmanned autonomous vehicle navigation (land, sea, and air), land survey devices, automotive positioning, timing and other precise-positioning applications.

The collaboration ensures smooth and easy integration of high-accuracy GPS/GNSS positioning and professional-level autopilots into control systems where safety and reliability matter
Septentrio is collaborating with MicroPilot, maker of professional UAV autopilots.
Septentrio receivers, including the small form factor mosaic modules, as well as the OEM board AsteRx-m3, will support seamless integration of positioning and orientation into MicroPilot’s autopilot ecosystem.
MicroPilot chose Septentrio GNSS receivers for their resilience to radio interference such as jamming and spoofing, as well as security and robustness with high-accuracy real-time kinematic (RTK) positioning.
Self-interference or self-jamming is a common occurrence in UAVs, where devices such as cameras, servos or antennas, which emit electromagnetic radiation, are located close to the GPS receiver. Incorporating GNSS technology that is resilient to jamming and spoofing, in combination with reliable professional-level autopilots, is key to safe and secure flight navigation, according to Septentrio.
“Adopting new and resilient technology in UAVs is vital, and we want to ensure a smooth integration process into professional drone systems,” said Gustavo Lopez, senior market access manager at Septentrio. “We are very excited about the strong collaboration between Septentrio and MicroPilot, which now provides new alternatives to drone companies looking for safe and reliable flight operations.”
In addition to developing autopilots, MicroPilot provides supporting software and services that enable customers to use development time more efficiently, reducing time to market.
“Working closely with Septentrio gives MicroPilot the ability to better leverage resilient and robust GNSS technologies strengthening our offering to the professional UAV market for safe and reliable flight control,” said Howard Loewen, president of MicroPilot.

Septentrio has released Open Service Navigation Message Authentication (OSNMA) functionality on its mosaic GNSS receiver modules. OSNMA offers end-to-end authentication on Galileo’s civilian signals, protecting receivers from OSNMA attacks.
Spoofing is a malicious form of radio interference, where faulty positioning information is sent to a receiver. For the last two years Septentrio has been working closely with the European Space Agency (ESA) during the test phases of OSNMA deployment. The know-how gained during this period is what allowed Septentrio to be one of the first to market with this advanced security feature.
OSNMA’s anti-spoofing capability complements Septentrio’s Advanced Interference Mitigation technology, AIM+, and further strengthens the overall security of Septentrio GNSS receivers, making them suitable for assured PNT solutions as well as critical infrastructure, such as 5G network synchronization.
“We are excited to start offering the OSNMA anti-spoofing technology in our industrial GNSS receivers. Our close collaboration with ESA enabled us to get the expertise needed to implement and validate this functionality in a timely manner,” said François Freulon, head of Product Management at Septentrio. “The addition of OSNMA to Septentrio’s already strong anti-jamming and anti-spoofing technology takes our receivers to a new level as the market leader of resilient positioning and timing solutions for industrial applications and critical infrastructure.”
OSNMA is now supported by the complete mosaic receiver family including GNSS RTK positioning modules, timing modules and heading receiver modules. It will also be rolled out on Septentrio’s latest generation of OEM receiver boards, AsteRx-m3, and subsequently on the ruggedized boxed receivers. Read more here.
iP-Solutions has added a GNSS receiver to its software-defined-receiver (SDR) front-end family. The new Eagle-2 works with software receivers in real time or records GNSS signals for post-processing.
For post-processing, Eagle-2 it supports most third-party receivers, such as MATLAB and C/C++ receivers.
The front end allows a user to work with two perfectly synchronized channels connected to two antennas.
The Eagle-2 supports GPS, Galileo, GLONASS , BeiDou, QZSS and SBAS.
Septentrio, a leader in high-precision GNSS positioning solutions, has launched three new products that support Japan’s high-accuracy Centimeter Level Augmentation Service (CLAS).
The three multi-frequency GNSS receivers support CLAS on a single device, thanks to the latest GNSS technology which receives the L6 signal, which transmits high-accuracy corrections from Japan’s QZSS constellation. This technology was developed in close cooperation with CORE, a leading integrator of high-accuracy positioning technology and services in Japan.
The mosaic-CLAS receiver is a GNSS module with a very small form-factor suitable for high-volume industrial applications.
The AsteRx-m3 CLAS is Septentrio’s best-in-class OEM board combining PPP-RTK CLAS with dual-antenna heading functionality.
The AsteRx SB3 CLAS features a ruggedized IP68 enclosure to protect it in harsh environments.
Septentrio is simultaneously offering various receiver types to the Japanese market ensuring an optimal match between products and customer needs in various applications including robotics, precision agriculture, construction, machine control and UAV.
“We are very pleased to jointly develop CLAS software on a new GNSS module, mosaic-CLAS,” emphasized Takahiro Yamamoto, director, GNSS Solution Business Center at CORE Corp. “This receiver puts CLAS GNSS technology on par with regular RTK receivers in terms of size as well as price. We believe that the realization of CLAS on the Septentrio mosaic platform will significantly promote the use of new QZSS services for industrial applications.”
“The launch of our new module and OEM board with CLAS support opens up new markets and use cases, which will benefit from centimeter-level positioning with fast acquisition time,” commented François Freulon, head of Product Management at Septentrio. “This launch demonstrates the technological leadership of Septentrio and our ability to provide dedicated solutions embedding L6 bands for the Japanese market.”
The CLAS PPP-RTK is the latest generation of GNSS correction services, combining near-RTK accuracy and quick initialization times with the broadcast nature of PPP. Receivers with built-in CLAS functionality offer sub-decimeter positioning accuracy right out of the box. Corrections for high-accuracy positioning are received directly from satellites, reducing the need for additional base stations or service subscriptions.

The 18-channel miniature full-constellation CLAW GPS Simulator is a fully self-contained, low size, weight, power and cost (SWaP-C) miniature GPS simulator. It is very popular in manufacturing environments as well as R&D applications that require consistent and repeatable local GNSS signals at low price points.
The CLAW simulator does not require external computers for processing and control — it works fully self-contained by simply applying power, and storing location/time/date data in internal non-volatile memory, or by storing complex vector data to simulate highly dynamic scenarios. The CLAW also can be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals. For 2022, JLT added driver support for a large number of additional GNSS front-end receivers when using the hardware-in-the-loop (transcoding) feature of the unit to, for instance, transcode from one GNSS system to another.
JLT offers an easy-to-use, highly configurable and cost-free SimCon Windows application program that is downloadable from the JLT website. SimCon allows random scenario generation and is thus usable to simulate leap-second events, Week 1023 rollover events, or any other GPS live-sky scenarios, including highly complex yet easy-to-create dynamic vector simulations.
For authorized U.S. government users, a version that does not have altitude and velocity limitations is popular for low-Earth-orbit (LEO) simulations. Multipath simulation allows use of the entire 18-channel simulator capability.
The unit can be field-upgraded with an easy-to-use in-field software upgrade feature. The CLAW is also very useful in GNSS receiver sensitivity testing for R&D or mass-production assembly lines as it allows accurate control of RF output power ranging from –100 dBm to less than –130 dBm with 0.1-dB resolution and typically better than 1-dB accuracy over the controllable power range.
The CLAW GPS Simulator also has a built-in RF signal generator with sweep, CW and random noise functions that are useful in simulating GNSS jamming scenarios, as well as GPS spoofing scenarios. The simulator comes in an FCC-certified metal desktop enclosure with numerous accessories.
The CLAW firmware has been updated to allow live-sky almanac and ephemerides to be automatically uploaded from various externally connected GNSS receivers. This makes simulations using real-time live-sky constellations (such as used in simulating spoofing attacks) an easy task. A free firmware update is available from JLT.

The new north mark design has been thoroughly tested to ensure it conforms to or exceeds customer expectations and maintains each antenna’s stringent IP69K rating.
OtoSphere is a small, add-on module to the ViaLite GPS RF over fiber link and any GNSS-based system, providing GNSS protection against GPS jamming attacks, making any receiver more resilient. It ensures continuity of timing and navigation capability and enables normal operation during a jamming attack. According to ViaLite, no other solution that offers such protection is as small, light, affordable, or easy to install. The Otosphere protection module adds resilience to critical GPS timing services.Using OtoSphere, GPS receivers are up to 50 times more resilient to jamming attacks on positioning, navigation and timing (PNT) systems compared with having no protection. The GPS receiver can continue working normally throughout the attack. Timing-critical infrastructures in areas such as defense and cybersecurity can now be protected from these attacks. The Otosphere has a unique interference filtering algorithm that combines patterns from two external omnidirectional antennas that pinpoints the direction of the attack, then directs a null toward the unwanted signal to reject and reduce disruptions.

Honeywell has unveiled a new accelerometer that delivers high performance and reliability in a small, rugged and low-cost package. The MV60 micro-electromechanical system (MEMS) accelerometer is designed for aerospace and defense, but also has potential uses in industrial and marine applications that require high-precision, navigation-grade accelerometers that are small, lightweight and require little power to operate.
The MV60 measures the acceleration experienced by an object during movement. These types of high-accuracy sensors are mainly used in inertial measurement units and navigation systems deployed on land, air and sea vehicles to measure velocity.
Additionally, inertial systems provide:
key orientation information for drilling operations
precision pointing and altitude determination for vehicles
platform stabilization
target location and surveying.
“The MV60 accelerometer is a technological breakthrough that leverages 50 years of Honeywell inertial sensor and MEMS experience to offer excellent reliability, ruggedness and performance,” said Matt Picchetti, vice president, Navigation and Sensors, Honeywell Aerospace. “Our customers in a wide range of markets will benefit from an accelerometer that is smaller, lighter and requires less power over similar offerings, and they won’t have to sacrifice performance.”
The highly reliable Honeywell MV60 accelerometer features a compact footprint of 1.2 square inches and has shock survivability of up to 5,000 g (g-force). It also offers bandwidth of greater than 300 Hz (hertz) — important for environmentally demanding missions.
The MV60 delivers accuracy and performance that previously had only been available in more expensive solutions. Now, customers have a more affordable, rugged, and small-scale offering suitable for the most demanding navigation applications.
Accelerometers are critical elements of navigation systems, and Honeywell provides a portfolio of precision accelerometers that deliver reliable performance at affordable prices to meet customer needs.
