# Overview of QuickGPS

QuickGPS lets you download Ephemeris data (current satellite position and timing information) from a server, instead of from the satellites, using an internet connection or data call. By using QuickGPS to download the data, TTFF (Time to First Fix) is significantly speeded up.

Note:

- The Ephemeris data are stored on HTC servers. QuickGPS is preconfigured to connect to these servers.
