Since satellites are always in different locations, it can be challenging to repeat a test environment for CRPA testing. Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a ...

Global navigation satellite system (GNSS) technologies such as global positioning system (GPS), GLONASS, COMPASS/Beidou, Galileo, QZSS, IRNSS/NavIC, and others are increasingly crucial for terrestrial ...

Modern GPS receivers are extremely sensitive signal detection devices. With tracking sensitivity’s below -160dbm, they can detect signals at 50dB below the ambient thermal noise in the channel.However ...

Raytheon UK has developed new GPS antennas designed to mitigate GPS jamming and spoofing, and it showcased them at the 2019 Defence and Security Equipment International exhibition (DSEI 2019) in ...
