About
The navigation receiver is designed to calculate the current coordinates and speed of an object in real time in both stand-alone and differential modes, form a second time stamp (1PPS), and exchange information with external equipment using RS232 interfaces. It supports 44 channels and receives L1 GPS C/A, L1 GLONASS СТ, GALILEO E1B/E1C, and SBAS L1 signals. The module provides offline (GPS+GLONASS, HDOP<4) accuracy of 2.5 m (plan, 2Drms), 4 m (height, rms) and 0.03 m/s (speed, rms), and differential coordinate accuracy of 1.5 m CEP. It supports dynamics up to 515 m/s speed and 3 m/s2 acceleration, with time-to-first-fix of 2 s (hot start), 27 s (cold start), 25 s (warm start), and 1 s (re-enter sync). Data output includes coordinates, time, course, speed, almanacs and ephemeris, and raw measurement information, in NMEA 0183 v4.10 binary and RTCM SC-104 formats, at output rates of 1, 2, 5, or 10 Hz. It interfaces via 2 UART ports (LVCMOS), operates on 1.7-3.6 V power input or 1.6-3.7 V battery power, and consumes 0.13 W in active detection mode, 0.07 W in active tracking mode, and 0.015 W in energy-saving pulse mode. Detection sensitivity is -147 dBmW (hot start) and -155 dBmW (cold start). Maximum operating height is 18000 m. The module is electrically and mechanically classified as a zero-level electronic module per GOST R 52003 and is certified as a measuring instrument. It is not flight-qualified and is not adaptable to customer requirements. Released in 2017 with a guaranteed service life of 3 years and an estimated production/delivery time of 7 months.
