Visualise Galileo satellite navigation signals on your Android
device!
For compatible devices that support the European Galileo Satellite Navigation System GalileoPVT uses the raw signals from visible Galileo satellites to calculate your position independent of the processed fix supplied by the device GNSS chipset.
A comparison can be made with the GPS and internal Android calculated locations with all points plotted on the map. Received signals are listed in a table (including signals from Glonass and Beidou if supported by the device as well as GPS and Galileo).
An augmented reality view allows you to visualise the position of live Galileo satellites in the sky as viewed by the device camera. This feature also works on devices that do not support Galileo by plotting the predicted satellite positions if no signals are received.
The raw signals can be logged to a file for post-processing in CSV or NMEA format.
To use the app you will need to grant the following permissions:
Camera - for the Augmented Reality view
Location - to make use of the raw GNSS measurements and Android location
Storage - to save logfiles and to save and read back assistance data
Network - to download assistance data from the Google SUPL server
Please note: The augmented reality view will only work if your device has a magnetometer - most phones do but not all. Check to see if the sky plot rotates as you turn the device.
Tested with the Samsung Galaxy S8+ Huawei P10 and Xiaomi Mi8. A list of devices that support Galileo can be found at the following address:

GalileoPVT was developed as an unofficial side project by engineers Tim and Paolo at the European Space Agency.
Please note that the text in the app is in English. We are a small team (2 people) working on a volunteer basis to provide a free app and it would cost money to employ translators to provide text in all other languages. We decided to make the app available in all regions because most of the information is presented in graphical or numerical form and we saw no need to restrict the distribution. Nevertheless several people have left 1* reviews because the app is not translated into their language. We understand that this may be frustrating but we would have to charge for a translated version. If you would be willing to pay for this please note in your review how much you would consider reasonable to pay and we will consider all such feedback for the next release bearing in mind the distribution of users by country. Thank you!
