The GT-88 is a Multi-GNSS receiver with high-stability and high-timing accuracy. It uses a new satellite signal selection algorithm developed by NTT, that provides outstanding multipath mitigation, especially in urban canyon environments. This receiver module supports GPS, GLONASS, Galileo, and QZSS satellite constellations. The module provides UTC time-synchronized timing signals (1PPS/10MHz) by receiving GNSS signals from the satellites. It achieves extremely high stability of 4.5ns (1 sigma) using a single band (L1 band - 1575.42 MHz), even better than atomic clocks made from rubidium. The module has a tracking sensitivity of better than -162 dBm and an acquisition sensitivity of as low as -148 dBm while consuming up to 68 mA of current.
The device is available in a 12.2 x 16 x 2.8 mm LCC package and is ideal for TRAIM, Single Satellite Tracking, Multipath Mitigation, Anti-Jamming and Anti-Spoofing applications. The GT-88 permits GNSS antennas to be mounted more freely than ever before including wall mounting and window mounting installations.
