НАВИА в Интернете

«Russian company NAVIA claims the world’s smallest GPS/GLONASS (and Galileo one day) receiver module.

The ML8088s measures 13 x 15 x 3 mm and boasts high sensitivity, simple 3.3V low power requirements and a very short cold start.

The chip — requiring no external components for basic operation — provides geographic coordinates and velocity plus time via RS232 or USB ports.

The receiver has 2 ‘searching’ and 32 parallel channels, each capable of operating on GLONASS L1, GPS L1 or Galileo E1. It also incorporates a 3-state jammer barrier feature, which claims to allow it to operate in a high interference environment.

Sensitivity ranges from minima of -145 dBm for cold start to -158 dBm whilst tracking. Time to first fix varies from 35 s cold start to 1 s on recapture.

Claimed internal accuracy (67%) is 3 m in the horizotal and 4 m vertical, with time (70%) to 20 ns. Max velocity is 515 m/s (1,000 kt) and max acceleration 3 g. Max height is 18,000 m (59,000 ft).

The ML8088s is based on an ARM microprocessor core, made in Cambridge, UK. Samples of the receiver module are now available.»
