The NEO‑M8T and LEA‑M8T concurrent GNSS modules deliver high integrity, precision timing in demanding applications world‑wide. Support for BeiDou and GLONASS constellations enables compliance with national requirements. Enhanced sensitivity and concurrent dual‑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 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. The M8T timing modules are delivered in u‑blox’ 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/TS 16949 certified sites, and are 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”.
