- Modern smartphones have an A-GPS chip in them, which allows them to track their location using satellites. However, not all phones use this technology. Some phones may only have limited A-GPS capabilities, which means that the phone cannot track its location as accurately as a smartphone with a full, autonomous Assisted GPS.

Global Navigation Satellite System (GNSS) receivers, whether in smartphones, cars, or other devices, calculate their position by computing signals from a minimum of four satellites from the available GNSS and regional satellite constellations.The receiver uses the time difference between the broadcast time sent by satellite and the time of signal r...
DXOMARK gathered a large set of devices from different brands and price segments in order to get a general idea of smartphone GPS positioning performance. To obtain a high-precision reference trajectory, DXOMARK used the Geoflex test platform mounted on top of a car, as shown in the image below: The test platform was composed of: 1. The most accura...
DXOMARK focused on the positioning error in the horizontal plane, measured as a RMS error, (root mean square), and did not take into account errors in elevation. The chart above illustrates the disparities that we observed: 1. The dark green section shows the devices that performed very well, with an average error below 5 meters of horizontal error...
The advent of four-constellation and dual-band navigation satellite technology represented a vast improvement over earlier satellite navigation systems. Newer GNSS receivers, including those that can receive triple-band signals, will become commonplace even in more economical smartphones. But what further improvements can we expect to see as next-g...
