LEA-M8S - u-blox M8 GNSS modules

Seamless upgrade of existing LEA-6 designs to multi-GNSS

The LEA-M8S module delivers concurrent GNSS location capability together with high-performance u-blox M8 positioning technology in the industry proven LEA form factor.

With its dual-frequency RF front-end, the LEA-M8S concurrent GNSS module is able to intelligently use the highest number of visible satellites from up to three GNSS systems (GPS/Galileo together with BeiDou or GLONASS) for more reliable positioning. The LEA-M8S provides exceptional performance with low system power, and is optimized for cost sensitive applications. It also supports message integrity protection, geofencing, and spoofing detection.

The LEA-M8S has sophisticated RF-architecture and interference suppression ensuring maximum performance even in GNSShostile environments. It features very low power GLONASS functionality. This 6th generation module in the LEA form factor allows simple migration from LEA-6x GPS and LEA-6N GPS / GLONASS modules.

The LEA-M8S combines a high level of robustness and integration capability with flexible connectivity options. The DDC (I²C compliant) interface provides connectivity and enables synergies with most u-blox cellular modules. For RF optimization, the LEA-M8S features a front-end SAW filter for increased jamming immunity.

Key Features:

  • Concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou)
  • Industry leading -167 dBm navigation sensitivity
  • Combines low power consumption and high sensitivity
  • Superior anti‑spoofing and anti‑jamming
  • UART, USB and DDC (I²C compliant) interfaces
  • Easy migration from LEA‑6 modules
