Multi-Constellation Satellite-Location Chip Supports China’s BeiDou System

The Teseo III single-chip standalone positioning product from STMicroelectronics can receive signals from multiple satellite navigation systems, including the Chinese BeiDou, the US GPS, European Galileo, Russia’s GLONASS and Japan’s QZSS.

The new Teseo III product family creates a new state-of-the-art in positioning accuracy by building on the industry–leading performance of ST’s Teseo II single-chip satellite-tracking ICs. The new generation also leverages the Company’s investment and support for sensor fusion as found in Automotive Dead Reckoning and Assisted-GNSS (Global Navigation Satellite System) functions.

The Teseo III product family is offered in two series: •The STA8089 series adds support for the BeiDou constellation to devices that remain pin-to-pin compatible with the Teseo II series, to enable fast customer-application migration.

The STA8090 series adds a new, more efficient power-management unit, along with support for China’s BeiDou satellites.

The Teseo III product family provides a single-chip solution integrating the RF, digital control circuits  and flash memory, to enable simultaneous tracking of multiple satellites regardless of their constellation and to deliver exceptional accuracy in urban canyons, where building and other obstructions make satellite visibility challenging. Like other products in the Teseo family, Teseo III combines high positioning accuracy and indoor sensitivity performance with powerful processing capabilities and superior design flexibility.

The Teseo III is now in qualification and will be available for sampling to customers in Q1 2014.
