The purpose of GNSS Compare is to make the life of developers and reasearchers easier. It’s an easy to use and easy to extend Android-based framework for calculating the PVT based on the raw GNSS measurements.
GNSS Compare is the winning Android application developed by the Galfins as part of the internal European Space Agency (ESA) competition called Galileo Smartphone App Challenge introduced in November 2017. The Challenge was about creating a smartphone application, which will allow the user to choose which satellite constellation to use for Position, Velocity and Time estimation. The aim was to increase the awareness about ESA’s Galileo programme and also to allow users from common public to compare the performance of Galileo signals with the performance from other global satellite navigation constellations.
