GNSS Collector Android App

Description

The satellite constellation above our heads and floating in space, provide us with rich and often missing data on positioning, navigation, and timing services on a macro and micro scale. This application provides an easy to use interface to collect raw GNSS data which can then be further analysed using our gnssmapper python package.

The app is written entirely in Kotlin and uses the Gradle build system.

The app makes considerable use of the following Firebase components:

• Cloud firestore stores all of our GNSS data and provides realtime data batching.

• Firestore database
• Firebase remote config
• Firebase auth
