Editor’s Note: This is the first article in a three-part series about software defined radios in GPS/GNSS simulators. Part 1: About GPS and various techniques that are used to advance signal ...
Commercial and military customers use CAST Navigation simulators in many contexts. Some need simple yet accurate verification of GNSS antenna performance. Others run scenarios modeling multiple ...
GPS and other GNSS services are susceptible to disturbances and attacks that could impact critical network synchronization New Adtran Oscilloquartz timing solutions featuring STL PNT technology boost ...
Lost or weak GNSS signals are always a concern – be it due to an urban canyon, a tunnel or other obstructions encountered in real-world applications. To traverse these satellite outages, an inertial ...
The four global GNSS systems are GPS (U.S.), GLONASS (Russia), Galileo (EU), BeiDou (China). Furthermore, there are two regional systems--QZSS (Japan) and IRNSS or NavIC (India). IBT Graphics Global ...
GNSS signals caused by reflection and diffraction. The signals: green denotes LOS signals, red and purple denote reflected signals, and blue and yellow denote diffracted signals. A pioneering study ...
Spire Global has won a $2.5 million contract from the U.S. National Oceanic and Atmospheric Administration (NOAA) to supply satellite weather data. The 9-month contract is part of NOAA’s Commercial ...
