GNSS RECEIVER WITH OPEN SOFTWARE INTERFACE
GPS | Galileo | GLONASS | BeiDou | SBAS

This open GNSS receiver platform has been developed in the frame of the GOOSE© project (the German acronym for »GNSS Receiver with open software interface«1) by Fraunhofer Institute for Integrated Circuits IIS. It is the only available development platform for GNSS receivers and it can provide an own hardware solution independent from commercial receivers.

The platform is dedicated to software developers, mobile communication operators, and system developers. Four separate components characterize the platform: a multi-frequency GNSS antenna, an analogue-frontend board, a baseband board, and the processor system.

Main benefits

  • Flexible development platform with multi-system and multi-signal real-time processing
  • Integrated antenna receiver combination (smart antenna)
  • Guaranteed stable phase center for all GNSS frequencies
  • Deployment in commercial PC or as an embedded platform
  • Allows deep coupling and vector tracking in real time
  • Access to correlation values

Features

    • 60 data pilot hardware channels
    • Up to 25 Hz raw data output (code, carrier, navigation data)
    • Supported signals:
      • GPS (L1CA, L2C L5)
      • Galileo (E1B, E5ab, E5AltBOC)
      • Optional SBAS (EGNOS)
      • BeiDou (B1), GLONASS (G1, G2) ready
    • Open GNSS Receiver Protocol (OGRP®), fully documented with parsing tool using CONVBIN from RTKLIB as RINEX converter
    • 10 MHz reference input
    • 10 MHz reference output
    • PPS output (1 Hz – max. 25 Hz)
    • 1 Ethernet port
    • 2 full speed USB2.0 ports
    • Ntrip client for RTKLIB

Performance

  • 1 PPS out: resolution 12 ns
  • 1 PPS out rise time: ~ 3 ns
  • Cold / warm start: depending on customers software implementation (startup time of SBC: 1 minute)
  • Re-acquisition: 1 – 2 s until satellite is re-used in position solution
  • Tracking: down to 30 dbHz
  • Acquisition: from 35 dbHz
