Assisted GNSS

An unique feature of ST- Assisted GPS is the dual-mode ability to seamless fall back from

the 14-days server-based prediction to 5-days autonomous prediction capability which self-

sustains on the field depending on usage patterns. This is very useful to keep quality of the

GNSS experience should a connected device loose its ability to contact the server for

coverage or roaming issues or any other wireless connectivity problem.

RealTime AGPS

RealTime Assisted GPS (RT-AGPS) solution is a server based Assisted GPS, therefore it

requires a network connection to download assistance data from the server.

RT-AGPS works downloading by an assistance server the real time ephemeris data. Server

access is allowed thanks to internal keyword provided by Teseo-LIV3F to the Host

processor and the acquired real-time data have to be provided to Teseo-LIV3F.

Proprietary NMEA commands are supported on Teseo-LIV3F to acquire the credential

access to the external server and to inject the data to Teseo-LIV3F.

STMicroelectronics partner provides available server solution access for free on Teseo-

LIV3F solution.

RealTime A-GPS allows continuous /real-time satellite position determination.
