59,9  53,9 


GA-001 UBLOX LEA-M8S Reference Board with sma connectors for active  GPS antenna. With firmware version 3.01.

The GA-001 Evaluation board makes evaluating the high performance of the u-blox 8 GPS/QZSS, GLONASS, BeiDou positioning engine simple. With a built-in USB interface for both power supply and high-speed data transfer, the need for an external power supply is eliminated. The GA-001 is compact, and it’s user-friendly interface and power supply options make it ideally suited for use in laboratories, vehicles and outdoor locations. Furthermore, the GA-001 can be used with a PDA or a notebook PC, making it the perfect companion through all stages of design-in projects. It’s a fully assembled and tested PCB for the u-Blox LEA-M8S integrated sma connectors for High Gain GPS antenna.

GA-001 features:

  • Power Supply & Data Link via USB
  • 43×38 mm, 10 gramm
  • USB 1.1 Device/USB V2.0 compatible
  • u-center GPS Evaluation Software
  • Easy to use
  • Extensive visualization and evaluation features
  • Supports AssistNow Online and AssistNow Offline A-GPS services
  • 1 USB port, 1 TTL UART port
  • Time pulse output LED and pin for time synhronization
  • Fully assembled and ready to use

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 u-blox M8 concurrent GNSS engine is able to intelligently use the highest number of visible satellites from two of the GNSS systems (GPS, GLONASS and BeiDou) for more reliable positioning. The LEA-M8S provides exceptional performance with low system power, and is optimized for cost sensitive applications.


The LEA-M8S module has sophisticated RF-architecture and interference suppression ensuring maximum performance even in GNSS hostile environments. It features very low power GLONASS functionality.


This 6th generation module in the LEA form factor allows simple migration from LEA-5 / LEA-6 GPS and LEA-6N GPS/GLONASS modules.


The LEA-M8S module 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.


LEA-M8S module uses u-blox GNSS chips qualified according to AEC-Q100 and are manufactured in ISO/TS 16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.


u-blox’ AssistNow Assistance supply aiding information, such as ephemeris, almanac, rough last position and time, reduce the time to first fix significantly and improve the acquisition sensitivity. AssistNow data are with u-blox M8 supporting both GPS and GLONASS constellation for faster acquisition than a GPS-only assistance. The extended validity of AssistNow Offline data (up to 35 days) and AssistNow Autonomous data (up to 6 days) provide faster acquisition after long off time.



  • Industry standard 22.4 x 17 x 2.4 mm package
  • UART and USB interface
  • Supports crystal for cost effectiveness or TCXO for exceptional kickstart performance
  • Onboard RTC Crystal for warm and hot starts
  • Antenna supervisor
