GNR-1© GNSS Navigation Receiver

Modern advanced receiver working with all existing constellations: GLONASS / GPS / BieDou / Galileo / NavIC. Designed to perform various tasks, both on land and in the air and at sea.

Features

  • GLONASS L1/L2 + GPS L1/L2 + BeiDou B1/B2 + Galileo E1/E5 + NavIC L5 satellite system calculating
  • All-in-view navigation using proven, GLONASS/GPS/BeiDou/Galileo/NavIC signal processor
  • Velocity (max) 8’000 m/s or 28’800 km/h
  • Standalone Position Accuracy < 1.5 m

All the latest modern transport systems are powered by GNSS (Global Navigation Satellite System) using all available GLONASS (Russia) / GPS (USA) / Galileo (European Union) / BeiDou (China) / NavIC (India) satellite systems and all future unmanned transport systems facilities will also use GNSS more. We can no longer imagine the world without navigation satellite systems. GNSS is, without a doubt, very important for precision operations using positioning and time servers. GNSS is used in construction, as well as for geodesy our entire planet.

The GNSS tracking mechanism of the GNR-1 board with 256 channels is capable of tracking all working constellations, which is also reserved for future running constellations. The GNR-1 is the ideal choice for CORS, the deformation control system and associated high-precision GNSS positioning applications. GNR-1 convenient and flexible to operate anywhere in the world. Compact and convenient housing allows you to easily install anywhere.
