The GNSS Compare app, winner of ESA’s Galileo Smartphone App Challenge, is now available for download on the Google Play Store for Android devices.
Taking advantage of the recent release of Android API 24 and the GnssMeasurement class, developers now have access to unprocessed pseudorange measurements in certain smartphones.
GNSS Compare is basically a tool for scientists to compare their algorithms. For those who are not GNSS experts, it can also serve as a teaching tool on the subject.
The Galileo Smartphone App Challenge was about creating a smartphone application that will allow the user to choose which satellite constellation to use for PVT estimation.

The aim was to increase the awareness about the European Union’s Galileo satellite navigation program and also to allow users from the public to compare the performance of Galileo signals with the performance from other global satellite navigation constellations.
The app has been tested on Samsung Galaxy S8 and Xiaomi Mi 8 phones. To download, visit the store.
