Low-cost antennas power high-precision space-based positioning

3 weeks ago | gpsworld.com | Tracy Cozzens

A novel method using signals of opportunity from low-Earth orbit (LEO) satellites is redefining what’s possible in satellite-based navigation. Researchers have developed a joint pseudo-range and Doppler positioning technique that taps into signals from constellations like Starlink and Iridium NEXT — without relying on traditional navigation signal structures.
U-blox launches triple-band GNSS module for fast-scaling robotics

3 weeks ago | gpsworld.com | Tracy Cozzens

U-blox has expanded its ZED form-factor portfolio with the ZED-F20P, a L1/L2/L5 triple-band GNSS module designed for high precision applications in ground and air robotics. The ZED-F20P provides OEMs deploying fleets of ground robots, drone light shows, and other dynamic autonomous platforms with centimeter-level RTK and PPP-RTK positioning, fast convergence times, and integrated security features.
Russian jamming creates 'Bermuda Triangle' in Baltic

3 weeks ago | gpsworld.com | Tracy Cozzens

Russian jamming of GPS signals is suspected to be the cause behind a new “Bermuda Triangle” of navigation confusion in the eastern Baltic Sea. In the Gulf of Finland, ships are disappearing from radar and Russian fighter jets are traveling through NATO airspace, according to Danwatch, a Danish news outlet. Ship monitoring service MarineTraffic shows the position of ships in completely different places than their actual positions, currently on land east of coastal city Primorsk, Russia.
Drones at War: Ukraine's bold attack shows future warfare era

3 weeks ago | gpsworld.com | Tracy Cozzens

On June 1, 117 drones rose up from wooden boxes inside Russia and attacked bombers parked on runways at military bases. The attack — dubbed Operation Spider Web — startled the world with its audacity. Approximately 41 planes were struck at four military bases, including the Belaya Air Base in Siberia hundreds of miles from Ukraine’s borders. In all, the attack destroyed a third of the bombers Russia uses as strategic cruise-missile carriers to destroy targets in Ukraine.
PEAK System offers inertial measurement unit

PEAK System has introduced the PCAN-GPS Pro FD, a configurable sensor module for measuring the position, attitude and acceleration of objects. It has a robust aluminum housing suited for measurement in harsh environments. The device is equipped with a powerful microcontroller (M7/M4 dual-core), a magnetic field sensor, a three-axis gyroscope, a three-axis accelerometer, and the u-blox NEO-M9N satellite receiver for GPS, Galileo, BeiDou, GLONASS, SBAS and QZSS.
Astradia star tracker designed to fill in for GNSS

3 weeks ago | gpsworld.com | Tracy Cozzens

Sodern announces the commercial launch of Astradia, a daytime star tracker which, when combined with an inertial navigation system, allows more precise and robust navigation under GNSS-denied environments. Specifically designed for civil and military aircraft, Astradia can operate day or night guided by stars. Astradia offers tracking capacity to within a few arc-seconds, equivalent to 1 meter at a distance of 70 km.
Calian GNSS launches anti-jamming antenna for critical infrastructure, marine and defense

3 weeks ago | gpsworld.com | Jesse Khalil

Calian GNSS has released its next-generation anti-jamming controlled reception pattern antenna (CRPA), the CR8894SXF+. The CR8894SXF+ is an advanced CRPA, engineered to provide efficient interference protection and real-time situational awareness across critical infrastructure, marine, and defense environments where GNSS continuity is mission critical. The CRPA is specifically-designed to provide a low-power and lightweight solution in a compact size.
