NEO/LEA-M8T: u-blox M8 concurrent GNSS timing modules
■Technical data sheet describing the NEO/LEA-M8T modules with concurrent reception of GPS/QZSS, GLONASS, BeiDou, and Galileo. They provide optimized accuracy and availability with survey-in and single-satellite timing. The modules feature market leading acquisition and tracking sensitivity, minimized power consumption with low duty-cycle operation, and maximized reliability with integrity monitoring and alarms.
●Overview:
■The NEO-M8T and LEA-M8T concurrent GNSS modules deliver high integrity, precision timing in demanding applications world-wide. Support for BeiDou, GLONASS and Galileo constellations in addition to GPS enables compliance with national requirements.Enhanced sensitivity and concurrent constellation reception extend coverage and integrity to challenging signal environments. Survey-in and fixed-position navigation reduce timing jitter, even at low signal levels, and enable synchronization to be maintained with as few as one single satellite in view. Support for on/off low duty cycle operation reduces power consumption for battery-powered applications.
■u-blox timing products include timing integrity measures with receiver autonomous integrity monitoring (RAIM) and continuous phase uncertainty estimation. They feature high dynamic range radios with both analog and digital interference mitigation, supporting applications in wireless communications equipment.
■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. The NEO-M8T includes an additional LNA, improving performance when connected directly to a passive antenna, with support for external antenna supply management if required. Both modules include flash memory for field upgrade. UART, SPI and DDC (I2C-compatible) interfaces provide connectivity and enable synergies with most u-blox cellular modules.
■The M8T timing modules are delivered in u-blox’s established LEA and NEO form-factors with standard pin-out, allowing ready migration from previous product generations.
■u-blox timing products can make use of u-blox AssistNow or industry standard aiding data. This reduces the time-to-first-fix and delivers exceptional acquisition sensitivity, even on first installation before precise location, time or frequency are known.
■u-blox M8 modules use GNSS chips qualified according to AEC-Q100, are manufactured in ISO/TS16949 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”.
