Standalone GPS provides first position in approximately 30-40 seconds. A Standalone GPS system needs orbital information of the satellites to calculate the current position. The data rate of the satellite signal is only 50 b/s, so downloading orbital information like ephemeris and almanac directly from satellites typically takes a long time. In AGPS, the Network Operator deploys an AGPS server. These AGPS servers download the orbital information from the satellite and store it in the database. An AGPS capable device can connect to these servers and download this information using Mobile Network radio bearers such as GSM, CDMA, WCDMA, LTE or even using other wireless radio bearers such as WIFI. Usually the data rate of these bearers is high, hence downloading orbital information takes less time.
