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 are also
supported.
