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.
Honeywell adds IMU to Navigation Lineup

Honeywell has expanded its navigation portfolio with the HG3900 inertial measurement unit (IMU), a lightweight and low-power tactical-grade device with accuracy and reliability comparable to larger near-navigation-grade IMUs.Honeywell will showcase the HG3900 IMU, along with the rest of its navigation products, at the Joint Navigation Conference in Cincinnati June 2-5, including a feature session on June 4.
Solar Storm may impact GPS

3 weeks ago | gpsworld.com | Tracy Cozzens

A geomagnetic storm expected today and tomorrow has been upgraded to G4 (severe) by the National Oceanic and Atmospheric Administration (NOAA). Solar storms can disrupt GPS and GNSS signals before they arrive on Earth. According to NOAA, a powerful coronal mass ejection (CME) erupted from the Sun the evening of May 30. Confidence in an Earth-directed component is good, but the CME arrival timing is more uncertain due to the current state of the solar wind.
3D scan of Titanic reveals new details of shipwreck

4 weeks ago | gpsworld.com | Tracy Cozzens

In 2022, deep-sea mapping company Magellan undertook the largest underwater 3D scanning project of its kind to create the first full-size digital scan of the Titanic. The luxury passenger liner sank in the North Atlantic Ocean on April 15, 1912, after striking an iceberg, and now rests 12,500 ft below the surface. Over three weeks, the Magellan team worked around the clock to capture the luxury vessel in unparalleled detail.
GNSS receivers show how earthquake sound waves move

1 month ago | gpsworld.com | Tracy Cozzens

Scientists at Japan’s Nagoya University have used Japan’s extensive network of GNSS receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake. Their results show sound wave disturbance patterns in unique 3D detail and provide new insights into how earthquakes generate these waves. The team published the results in the journal Earth, Planets and Space (May 29, DOI 10.1186/s40623-025-02211-y).
