STA2058 Teseo GPS Platform high-sensitivity baseband

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 t.
