1. uBLox Max-7Q with Radiometrix NTX2B 2. uBlox NEO-M8T with Radiometrix NTX2B 3. uBlox NEO-M8T with Radiometrix MTX2 The NEO-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 single SV timing 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. 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 uBlox M8 Product Summary uBlox NEO-M8T Data Sheet can use U-Center for Windows setting or test signal For the project we have 3 different models each with their different components which suffice your need: 1. ublox NEO-M8T GPS module & ublox Max7Q 2.
