A multi-frequency multi-constellation GNSS development platform with an open interface

Abstract

This paper presents the GOOSE GNSS open receiver platform. The platform is based on a multi-frequency multi-constellation GNSS receiver which can be deployed either as a fixed PC receiver or as an embedded portable one. The main feature of this platform is to provide to GNSS software developers the possibility to have a deeper control on receiver hardware and to replace all the provided software functionality with their own software modules. This is possible with the open interface protocol called Open GNSS Receiver Protocol (OGRP), which has been developed by Fraunhofer in the same project. The results show how the receiver hardware performs in the different scenarios.
