First Monolithic Quad Band Satellite Receiver for Industrial Automotive

STMicroelectronics has made a significant advancement in satellite navigation technology by developing the first quad-band monolithic satellite navigation receiver tailored for automotive and industrial applications. The Teseo VI multi-constellation design offers precise GNSS positioning accurate to a few centimetres on a single die, setting a new standard in the industry. Notably, it is the first receiver to feature dual ARM Cortex-M7 controller cores, enhancing its processing capabilities.

The VI STA8600A, a part of the Teseo VI family, supports innovative features such as dead reckoning automotive way (TESEO-DRAW) and dead reckoning unplugged mode (Teseo-DRUM). These functionalities ensure high-accuracy positioning even in challenging environments like tunnels, garages, and densely populated urban areas. The VI+ ST8610A variant provides ample resources to support RTK/PPP precision algorithms on chip, thanks to the inclusion of two M7 cores.

Collaborating with Point One Navigation, STMicroelectronics aims to boost GNSS positioning for various applications, including robot lawnmowers and NB-IoT modules. The company's in-house development of the Teseo APP2 STA9200MA, which operates dual cores in lockstep, offers hardware redundancy suitable for safety-critical applications like road vehicle guidance, meeting ISO 26262 ASIL-B functional safety standards.

All Teseo VI variants leverage ST's RF architecture and GNSS baseband design to provide quad-band GNSS support across L1, L2, L5, and E6 frequencies. This unique capability allows the receiver to acquire and track only L5, significantly enhancing performance in challenging scenarios such as urban canyons and jamming environments.

The Teseo VI receivers also support open service navigation message authentication (OSNMA) from the Galileo constellation, a crucial feature in preventing spoofing attacks. By cryptographically authenticating the message source using a message authentication code (MAC), the receiver ensures signal authenticity and integrity, enhancing overall security.

For the automotive industry, Teseo VI chips and modules are poised to revolutionize advanced driving systems, smart in-vehicle technologies, and safety-critical applications like autonomous driving. These devices are also expected to enhance positioning capabilities in various industrial sectors, including asset tracking, mobile robotics, smart agriculture, and timing systems.

Luca Celant, General Manager of Digital Audio and Signal Solutions at STMicroelectronics, highlighted the groundbreaking nature of the Teseo VI receivers, emphasizing their multi-constellation integration and dual ARM core architecture for ASIL-level safety in driving applications. The receivers' integration is made possible by ST's proprietary embedded Non-Volatile-Memory (PCM) technology, ensuring robust performance in demanding automotive environments.

The Teseo VI+ variant offers compatibility with enhanced positioning engines developed by third-party ST Authorized Partner companies, enabling centimetre-level position accuracy in real-time kinematics applications. Moreover, the devices boast a comprehensive set of hardware cybersecurity features, including secure boot, over-the-air firmware updates, and output data protection, aligning with the latest cybersecurity standards.

STMicroelectronics' commitment to cybersecurity is further demonstrated through compliance with UNECE R155 and ISO 21434 specifications, emphasizing cybersecurity by design. The Teseo VI GNSS satellite receiver family also includes two new automotive modules, the Teseo-VIC6A and Teseo-ELE6A, designed to simplify integration and optimize performance on customer platforms.
