Supply ST Teseo Satellite Navigation Chip, Supply STA8600ASP Automotive TeseoVI Quad-Bands Multiconstellation GNSS Receiver

Shenzhen Mingjiada Electronics Co., Ltd. maintains a long-term stock of the full range of STMicroelectronics (ST) Teseo satellite navigation chips, including the STA8600ASP—a single-chip, automotive-grade, quad-frequency, multi-constellation GNSS receiver from the Teseo VI series. This device is ST’s sixth-generation GNSS positioning SoC, designed for L2+/L3 driver assistance, in-vehicle navigation, V2X and high-precision industrial positioning applications. It integrates an embedded RTK precision positioning algorithm and a hardware security module (HSM), and complies with the AEC-Q100 automotive standard.

I. Product Overview: Introduction to the ST STA8600ASP Teseo VI Quad-Frequency GNSS Single-Chip
The STA8600ASP is a quad-frequency GNSS receiver IC within ST’s Teseo VI family, featuring an embedded RTK algorithm and a hardware security module (HSM). The chip integrates a dual-core Arm® Cortex®‑M7 processor, RF front-end, baseband processing engine and embedded phase-change memory (PCM) onto a single die. It requires no external Flash memory and can independently perform multi-frequency raw measurements and centimetre-level RTK processing.

The STA8600ASP integrates a Hardware Security Module (HSM) microcontroller to support secure boot. Combined with signal and interface integrity mechanisms, this makes the STA8600A an ideal choice for applications with extremely high integrity requirements. It supports highly advanced anti-jamming and anti-spoofing mechanisms, mitigating attacks through independent L5 signal acquisition and tracking, as well as Galileo OSNMA functionality. Its innovative RF architecture and GNSS baseband design enable it to support emerging Low Earth Orbit (LEO) constellations.

III. Key Features of the STA8600ASP
1. High-Precision Positioning with Four Frequencies and Six Constellations
The STA8600ASP supports the simultaneous reception and processing of signals from six global navigation satellite systems (GPS, Galileo, GLONASS, BeiDou, QZSS and NAVIC), covering the four frequency bands L1, L2, L5 and E6. This multi-frequency reception capability effectively eliminates ionospheric errors, achieving sub-metre standard PVT positioning accuracy.
2. Embedded RTK Centimetre-Level Precision Positioning
The STA8600AP and STA8600ASP models feature built-in RTK (Real-Time Kinematic) precision positioning algorithms, enabling centimetre-level positioning accuracy without the need for an external host device. This feature makes them particularly suitable for applications requiring extremely high positioning accuracy, such as drones, robotic lawnmowers and precision agriculture equipment.
3. Continuous positioning in GNSS dead zones
Supporting TESEO-DRAW (Trajectory-based Automotive Positioning) and Teseo-DRUM (Trajectory-based Offline Mode), the system maintains continuous high-precision positioning through inertial sensor fusion even in environments where satellite signals are obstructed, such as tunnels, underground car parks and urban canyons.
4. Highly Integrated SoC Architecture
The chip features two independent Arm® Cortex®-M7 processor cores, with sufficient MIPS and memory resources to support the direct on-chip execution of quad-frequency algorithms. Utilising STMicroelectronics’ proprietary phase-change memory (PCM) technology, it eliminates the need for external Flash memory, effectively simplifying design, reducing BOM costs and minimising supply chain constraints.
5. Comprehensive Security Protection
The STA8600ASP integrates a Hardware Security Module (HSM), supporting secure boot, secure firmware updates and secure connections, and complies with the ISO/SAE 21434 automotive cybersecurity standard. It also features advanced anti-jamming and anti-spoofing mechanisms, effectively defending against various types of attacks through independent L5 signal acquisition and tracking, as well as Galileo OSNMA functionality.
6. Future-Proof Architecture
Its innovative RF architecture and GNSS baseband design enable reception of signals from emerging Low Earth Orbit (LEO) navigation constellations, providing ample scope for future navigation technology evolution.
