UTRAQ L100 IRNSS NavIC GAGAN GPS Receiver Module

U-TRAQ L100 is an ultra-compact POT(Patch on Top) GPS / NavIC module. UTRAC L100 NavIC is a standalone GNSS module in an SMT type based on ST high sensitivity navigation engine. It has tiny package and extremely low power consumption makes it easier to be applied to power sensitive devices. This UTRAC GPS module variant has excellent tracking sensitivity of -162 dBm. 

U-TRAQ is powered by ST Microelectronics Chipset on GPS technology which enables it to do tracking at -162dBm with Hot Start at 1 second and Cold Start at 30 second. The position is 2.5m CEP and velocity is 0.1 m/s. It has high performance ARM946 MCU (Upto 196MHz).

U-TRAQ is uniquely positioned for the Tracking navigational applications. Its superior acquisition and tracking capabilities ensure continuous location availability even under poor visibility and weather condition. U-TRAQ supports NMEA message protocol for IRNSS to communicate the location and timing information to the world.

U-TRAQ GPS receiver Modules are based on IRNSS supported by GAGAN/NaviC signals, designed using L5 and S bands. But in our UTRAQ GPS receiver Modules, they are designed for two RF bands:L5 frequency and L1 frequency, L5 frequency which is NaviC Frequency, and L1 frequency which is GPS/GLONASS frequency. Where L100 has dual band patch antennas connected to two RF inputs of the board which receives the signals from the satellite. The baseboard also has a Super Capacitor, which helps to retain the last track details and helps for hot start with tracking in less than 1 second!
