Trimble Copernicus GPS Receiver

Internal to Raveon’s M7 series of GPS transponders is a GPS receiver module made by Trimble.  It is their Copernicus II GPS receiver module.  Many of the M7′s performance specifications are driven by the use of this receiver module.  The Copernicus II is ideally suited for vehicle tracking systems, AVL, asset tracking, and personal location.   Details of the module are available on Trimble’s website at:

The following is a summery of the Copernicus GPS modules features and performance:

Overview

Trimble’s Copernicus® GPS receiver delivers proven performance and Trimble quality for a new generation of position-enabled products. It features the Trimble revolutionary TrimCore™ software technology for extremely fast startup times and high performance in foliage canopy and urban canyon environments. The Copernicus module is a complete 12-channel SBAS (which includes WAAS, EGNOS) capable GPS receiver in a thumbnail-sized module. Each module is manufactured and factory tested to Trimble’s highest quality standards.

Key Features:

  • 2.54 mm T x 19 mm W x 19 mm L
  • 94 mW typical continuous tracking
  • Supports SBAS (WAAS, EGNOS)
  • Active or passive antennas
  • NMEA, TSIP, TAIP protocols
  • RoHS-Compliant (Pb-free)

The sensitive Copernicus II GPS receiver can autonomously acquire GPS satellite signals and quickly generate reliable position fixes in extremely challenging environments and under poor signal conditions The unit also accepts aided GPS (A-GPS) data for faster startups in very weak conditions.  The Copernicus II GPS module is a complete drop-in, ready-to-go receiver that provides position, velocity, and time data in a user’s choice of three protocols Trimble’s powerful TSIP protocol offers complete control over receiver operation and provides detailed satellite information.
