GNSSTest is a free professional app developed by Embest for testers who need to perform GPS/GNSS functional and performance tests. Written in Kotlin, this app provides a comprehensive solution for GPS/GNSS testing, making it easier and faster to perform tests. With GNSSTest, you can test in batches and configure everything to fit your test cases.

One of the awesome features of GNSSTest is its support for a wide range of constellations, including GPS(L1/L5), Glonass, QZSS(L1/L5), BeiDou, Galileo(E1/E5), and NavIC(L5) constellations. This makes it a very powerful testing tool, as it supports almost all Android GNSS APIs. Another great feature is its customizability. In professional mode, you can freely combine the test tasks you want and push the test config to do custom testing. GNSSTest also provides NMEA and raw data recording, as well as CEP calculation, making it a complete GPS/GNSS testing solution.
