GPS One aims at exercising 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) and SBAS (Regional) to compute accurate locations. Network PositioningLeverages on Google knowledge of cell towers and Wi-Fi access points to compute coarse locations. Fused LocationLeverages on Google Play Services (aka GMS) to compute locations based on several sources (GNSS, Wi-Fi, cellular, Bluetooth.) - GeofencingLeverages on Google Play Services (aka GMS) to send user alerts when crossing predefined fences. AutomationA 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.
