Bobcat-1 was a three-unit CubeSat developed and built at Ohio University’s Avionics Engineering Center in Athens, Ohio, and was named after the university’s mascot. FIGURE 1 shows Bobcat-1 with and ...

Satellite orbits and clocks are determined using observation data from a global GNSS network together with other parameters such as station coordinates, earth rotation parameters and troposphere ...

Part 3: Testing using SDRs and GPS signal examples. All about GPS/GNSS simulators. The application of satellite navigation in everyday products has increased exponentially, with integrated GNSS ...

A new study reveals advanced methods for improving orbit determination (OD) of large constellations of Low Earth Orbit (LEO) satellites, utilizing Global Navigation Satellite System (GNSS ...

Currently, Global Navigation Satellite Systems (GNSS) are typically placed in medium Earth orbits about 6,300 to 12,500 miles (10,000 to 20,000 kilometers) above the surface and they send location ...

Realistically, there is no singular solution to replace GPS, but we can make it more resilient with complementary AltPNT technologies.

The LEO satellite system employs multiple signal beams to enhance navigation reliability, ensuring accurate positioning even when traditional GNSS systems are compromised.
