Product overview
Description
STA2058 is the high-sensitivity baseband of TESEO GPS platform which include the STA5620 RF Front-End.
The embedded Flash memory enables the equipment manufacturer to load the entire GPS software (including tracking, acquisition, navigation and data output) after customizing its interfaces to his needs. A standard GPS library is available from ST.
TESEO is the ideal solution for consumer, handheld, PND (portable navigation), in vehicle navigation and telematics systems.
SBAS (WAAS and EGNOS) feature is also supported.
