Mingjiada Supply ST TESEO-ELE6A TeseoVI Quad-Band Multiconstellation Global Navigation Satellite System Standalone Module

Abstract (Meta Description):​ Mingjiada Electronics maintains a long-term stock of ST (STMicroelectronics) TESEO-ELE6A automotive-grade quad-frequency TeseoVI+ GNSS modules, featuring a built-in dual-core Cortex-M7 processor, supporting L1/L2/L5/E6 quad-frequency multi-satellite positioning and RTK/PPP, and compliant with AEC-Q104 automotive certification. Widely applicable to smart in-vehicle systems, ADAS, autonomous driving and industrial IoT positioning scenarios, it is the preferred choice for mid- to high-end in-vehicle and industrial precision positioning applications.

Product Overview — ST TESEO-ELE6A Automotive-Grade Quad-Frequency GNSS Module
The ST TESEO-ELE6A is an easy-to-integrate, automotive-grade, quad-frequency, multi-constellation Global Navigation Satellite System (GNSS) standalone module. It incorporates the Teseo VI+ single-chip standalone positioning receiver IC, capable of simultaneously tracking six major satellite systems: GPS, Galileo, GLONASS, BeiDou, QZSS and NavIC (IRNSS).
The Teseo-ELE6A module delivers high-quality GNSS measurement data to support PPP/RTK algorithms running on either an internal or external MCU. Thanks to a dedicated SDK and a Cortex®-M7 core dedicated to PPP/RTK positioning algorithms, the Teseo-ELE6A can be embedded in high-precision positioning applications without the need for an external host.
The Teseo-ELE6A offers real-time assisted GNSS functionality. It supports firmware configurability, and firmware upgrades can be performed on both cores.
Measuring just 17.0 mm × 22 mm, the Teseo-ELE6A delivers exceptional accuracy thanks to its on-board temperature-compensated crystal oscillator (TCXO) and reduces time-to-first-fix (TTFF) through its dedicated real-time clock (RTC) oscillator.
As a specialist distributor of electronic components from stock, Mingjiada Electronics maintains a long-term stock of ST’s TESEO series GNSS modules (Teseo-ELE6A), providing genuine manufacturer products and technical documentation.

Developed by STMicroelectronics (ST), the Teseo-ELE6A is a module housed in a 54-pin LCC package (17.0 mm × 22 mm). It integrates:
• STA8610A
• RF surface acoustic wave (SAW) filter
• ASM330LHHX 6-axis gyroscope and accelerometer
• 32 Mbit four-channel flash memory and 32 Mbit four-channel RAM
• 26 MHz temperature-compensated crystal oscillator (TCXO)
• 32 kHz real-time clock (RTC)
• Electrostatic discharge (ESD) diode protection on the ANTENNA_IN pin (part number: ESDAXLC6-1BT2Y).
