GNSS Module

  • Multi-constellation multi-frequency GNSS signals tracking (including S-band)
  • Standalone positioning;
  • Access to raw GNSS measurements
  • RTCM 3.3 (MSM + Legacy messages), NMEA 2.3, NMEA 4.11, NTL Binary output data format
  • Compact and lightweight

The KV103.SMT OEM GNSS module provides standalone positioning with SBAS supports as well as the generation of GNSS measurements.
The KV103.SMT supports signals reception from GPS, GLONASS, NavIC(IRNSS) and SBAS. Increasing the number of visible satellites reduces the time to first fix and improves positioning reliability.
The combination of compact design, light weight, excellent sensitivity and low power consumption consumption allow the KV103.SMT to serve a wide range of GNSS applications.
