ECHO is an equipment configurable in GNSS Datalogger (GPS, GALILEO, GLONASS, ...) or GNSS Dataplayer, studied for the development and test of GNSS equipment.

• Digital and RF generation (GNSS Signal Playback): ECHO-P Datasheet
• Digital and RF Signal Recorder (Wideband multichannel Signal Recorder): ECHO-L Datasheet
• Stores and restores GNSS datafiles up to many TB
• Multiple signal recording and replay is synchronized with very high precision (constant shift drift between 2 channel)
• Hardware exists in 1, 2 or 3 channel configuration either for multiconstellation, multifrequency or reflectometry experimentation
• Mobile and autonomous version for Datalogger (about 12 kg)
