GPS One

GPS One aims to exercise Android Positioning features.

It is a great tool for:

- Users that want to look at their device capabilities.

- Device manufacturers and positioning technologies engineers to ensure their implementations are correct with regards to Android framework.

The following features are covered:

- GNSS (Global Navigation Satellite Systems)

Leverages on GPS (USA), GLONASS (Russia), BeiDou (China), Galileo (EU), QZSS (Japan), NavIC (India) and SBAS (Regional) to compute accurate locations.

- Network Positioning

Leverages on Google knowledge of cell towers and Wi-Fi access points to compute coarse locations.

- Fused Location

Leverages on Google Play Services (aka GMS) to compute locations based on several sources (GNSS, Wi-Fi, cellular, Bluetooth...)

- Geofencing

Leverages on Google Play Services (aka GMS) to send user alerts when crossing predefined fences.

- Automation

A useful feature to repeat GNSS starts/stops in order to benchmark the device performances: TTFF (Time To First Fix) and HE (Horizontal Error compared to a reference location) percentiles in Cold/Warm/Hot start conditions.
