GPS LEA-M8T GPS breakout board with Precision Timing description The LEA-M8T standalone concurrent GNSS modules are built on the exceptional performance of the M8 GNSS (GPS, GLONASS, BeiDou, QZSS, SBAS and Galileo-ready1) engine in the industry proven NEO and LEA form factors. This 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 I2C interfaces provide connectivity and enable synergies with most u-blox cellular modules. This 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. 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 Active GNSS antenna support UART, I2C and USB interfaces u-center Evaluation Software Dimensions: 38x32 mm Weight: 4 gr.
