STMicro has launched the Teseo VI family of global navigation satellite system (GNSS) receivers for high-volume precise positioning applications. These quad-band GNSS receivers support multiple constellations and frequency bands, enabling high-accuracy positioning for various automotive and robotics applications.
The Teseo VI quad-band GNSS receivers are described as the first chips in the market to “integrate multi-constellation and quad-band signal processing in a single die.” The single-chip design allows for compact products and accelerates time to market.
The new Teseo VI GNSS family includes the Teseo VI STA8600A, Teseo VI+ STA8610A, and the Teseo APP2 STA9200MA. All variants integrate dual independent Arm Cortex-M7 cores with ST’s proprietary phase change memory (PCM) technology, eliminating the need for external memory.
They are targeted at applications in advanced driving systems, autonomous vehicles, asset tracking, smart agriculture, and robot deliveries. Other quad-band GNSS modules include the Quectel LG290P and u-blox X20.

The Teseo VI quad-band GNSS receivers are compatible with STMicroelectronics’ TESEO-DRAW dead reckoning firmware and TESEO-SUITE, a software suite for managing and configuring the Teseo VI family.
The Teseo VI product family also includes the Teseo-VIC6A (Teseo VI STA8600A) and the Teseo-ELE6A (Teseo VI+ STA8610A) modules for easier integration of the ICs on consumer platforms. Pricing for the Teseo VI product family is currently not available but samples are available on request via the STMicro website.
