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.
