SAPHYRION produces and offers to the GNSS receivers’ developers a complete set of new instruments allowing efficient record and playback of GNSS signals at all the available bands of GALILEO, GPS, GLONASS, QZSS, BEIDOU (L1/L2/L5, G1/G2, B1/B2, E1/E5/E6), over up to four 50 MHz bandwidth channels in parallel and with a quantization depth of 8-bits. These units are also exploited in GNSS signal integrity monitoring applications.
