STMicroelectronics Teseo APP multiband GNSS receiver

STMicroelectronics has introduced a multifrequency satellite-navigation receiver chipset, suitable for safety-critical automotive applications and precise positioning at the decimetre and centimetre-level for PPP (Precise Point Positioning) and RTK (Real Time Kinematic) applications.

By tracking satellites of all GNSS (global navigation satellite system) constellations simultaneously on at least two of the frequencies used by each system (instead of one in other products), ST’s automotive-quality Teseo APP (Automotive Precise Positioning) receiver provides high-quality raw GNSS data for PPP and RTK algorithms, which allows proper positioning and rapid convergence time worldwide.

The receiver monitors the integrity of the satellite data to alert the system if accuracy is degraded for any reason. This permits Tier-1 manufacturers to certify safety-critical systems in accordance with the automotive industry functional-safety standard, ISO 26262, up to the highest Automotive Safety Integrity Level (ASIL). It also integrates a secure microcontroller for secure system boot and data-output authentication to keep sensitive data safe from attack.
