LEA-M8T GPS/QZSS GLONASS BeiDou Timing and RAW data module

LEA-M8T GPS/QZSS, GLONASS, BeiDou Timing and RAW data EVAL module with USB, UART, RS-232 interface and with SMA connector for active GPS antenna.

The LEA-M8T 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 LEA-M8T Evaluation board 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 LEA-M8T Evaluation board 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 LEA-M8T with integrated sma connectors for High Gain GPS antenna.

The LEA-M8T standalone concurrent GNSS modules are built on the exceptional performance of the u-blox M8 GNSS (GPS, GLONASS, BeiDou, QZSS, SBAS and Galileo-ready1) engine in the industry proven NEO and LEA form factors. The u-blox M8 series of modules offers high sensitivity and rapid acquisition in applications requiring low system power. The LEA-M8T modules meet the requirements for GNSS timing applications (including fixed location, survey-in and RAIM). The modules deliver multi-GNSS, raw measurement data (code and carrier phase, Doppler) and multi-GNSS, QZSS L1S and IMES message data. Both modules offer easy design migration from previous generations adding BeiDou and concurrent multi-GNSS capability to existing products. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments.

The LEA-M8T includes a SAW filter and antenna power supervision and is perfect for use with active antennas or antenna signal distribution systems. Both modules include Flash memory for field upgrade if required. UART, SPI and DDC (I2C compatible) interfaces provide connectivity and enable synergies with most u-blox cellular modules. u-blox M8 modules use GNSS chips qualified according to AEC-Q100, are manufactured in ISO/TS 16949 certified sites, and fully tested on a system level. 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 services supply aiding information, such as ephemeris, almanac and time, reducing the time to first fix significantly and improving acquisition sensitivity. The u-blox M8 generation extends validities of AssistNow Offline data (up to 35 days) and AssistNow Autonomous data (up to 6 days), providing the benefits of faster acquisition for longer durations since last use.

Highlights:

• Concurrent reception of GPS/QZSS, GLONASS, BeiDou
• Market leading acquisition and tracking sensitivity
• Optimized accuracy and availability with Survey-in and single-satellite timing
• Minimized power consumption with low duty-cycle operation
• Maximized reliability with Integrity monitoring and alarms
• Multi-GNSS Raw data, IMES Message data
• Backward compatible with LEA-5T, LEA-6T and NEO-6T
