会社ブログについて STMicroelectronics GNSS Module Buyback | Applications Covering Autonomous Driving, Robotics and Trackers; Mingjiada Offers Cash for the Full Range of Teseo Modules

Mingjiada Electronics is seeking long-term supplies of STMicroelectronics (ST) GNSS modules – a specialist recycling platform for high-precision positioning core components

I. Introduction to STMicroelectronics GNSS Modules

STMicroelectronics (ST) is a world-leading semiconductor manufacturer; its Teseo series of GNSS (Global Navigation Satellite System) modules is renowned in the industry for its high precision, low power consumption and multi-constellation compatibility. This product series incorporates ST’s proprietary Teseo positioning receiver chip, which simultaneously supports signals from six major satellite constellations: GPS, Galileo, GLONASS, BeiDou, QZSS and NavIC (IRNSS).

Core Product Series

1. Teseo III Series (Representative Models: Teseo-LIV3F / Teseo-LIV3FL)

The Teseo-LIV3F is an easy-to-use standalone GNSS module, incorporating the Teseo III single-chip positioning receiver IC, which supports multiple constellations simultaneously. The module features a tracking sensitivity of –163 dBm and a positioning accuracy of 1.5 m CEP, with 16 Mbit of embedded flash memory supporting data logging and firmware upgrades. Measuring just 9.7 × 10.1 mm, the module is housed in a miniature 18-pin LCC package and operates within a temperature range of –40 °C to +85 °C.

2. Teseo IV Series (Representative models: Teseo-LIV4F)

The Teseo-LIV4F module incorporates the Teseo IV single-chip GNSS receiver IC, supporting multiple constellations (GPS/Galileo/Glonass/Beidou/QZSS) and providing either positioning data or raw measurement data. The module offers sub-metre positioning accuracy and a tracking sensitivity of –162 dBm, housed in a 9.7 × 10.1 mm micro LCC 18-pin package. The Teseo-LIV4F delivers exceptional accuracy thanks to its on-board temperature-compensated crystal oscillator (TCXO) and reduces time-to-first-fix (TTFF) via a dedicated real-time clock (RTC) oscillator.

3. Teseo VI Series (Representative Models: Teseo-ELE6A / Teseo-VIC6A)

The Teseo-ELE6A is STMicroelectronics’ flagship automotive-grade GNSS module, representing the sixth generation of positioning receivers. The module supports quad-frequency (L1/L2/L5/E6) multi-constellation reception and features a built-in dual-core Arm® Cortex®-M7 processor, enabling high-precision positioning algorithms such as PPP and RTK to run directly within the module. Its key technical features include:

192 signal tracking channels (96 data + 96 pilot)

AEC-Q104 automotive qualification, operating temperature range -40°C to +105°C

Integrated ST Automotive 6-axis inertial sensor, supporting the Teseo-DRAW dead reckoning algorithm

Support for SBAS systems and signal integrity protection (anti-jamming/anti-spoofing)

The Teseo-VIC6A measures 16 × 12 mm and the Teseo-ELE6A measures 17 × 22 mm; both simplify integration into customer platforms.

4. Other Featured Modules

ST87M01: The world’s first all-in-one module integrating NB-IoT cellular connectivity, GNSS and Wi-Fi positioning, designed specifically for large-scale cellular IoT applications such as asset tracking and smart tags.

Teseo VI receiver chips (STA8600A, STA8610A): Equipped with two independent Arm® Cortex-M7 processor cores, they support quad-frequency GNSS (L1, L2, L5 and E6) and feature unique independent acquisition and tracking capabilities for the L5 band.

II. Key Application Scenarios

Thanks to their high accuracy, low power consumption, multi-constellation compatibility and automotive-grade reliability, STMicroelectronics’ GNSS modules are widely used in the following fields:

1. Automotive Electronics and Intelligent Driving

The Teseo VI automotive-grade ICs and modules are suitable for standard navigation, in-vehicle infotainment systems (IVS), as well as automotive applications requiring precise positioning and ASIL compliance, such as autonomous driving and advanced driver-assistance systems (ADAS). Specifically, these include:

ADAS and autonomous driving: Providing sub-metre or even sub-centimetre absolute position data for lane-level navigation and adaptive cruise control

Autonomous driving domain controllers: Providing high-quality raw measurement data (carrier phase, Doppler frequency) to support RTK and PPP algorithms

In-vehicle navigation and emergency calls: Vehicle tracking, emergency calls (eCall), fleet management, car-sharing, etc.

Cellular Vehicle-to-Everything (C-V2X): Collaborating with partners such as Trimble to provide high-precision positioning solutions for C-V2X

2. Industry and Robotics

Field robots and lawnmowers: Providing high-precision positioning support in complex environments

Unmanned Aerial Vehicles (UAVs): Positioning and navigation for commercial drones

Precision agriculture: Automatic navigation of agricultural machinery and precision operations

Asset tracking and logistics: Cargo tracking, container positioning and fleet management

3. Internet of Things and Consumer Electronics
