The UM442 can simultaneously track GPS, BDS, GLONASS and Galileo. It also supports SBAS and QZSS. It uses Uncore’s new-generation Nebulas II chip and UGypsophila real-time kinematic (RTK) algorithm. Based on high-performance data-sharing technology and the simplified operation system of the Nebulas II chip, the UGypsophila RTK algorithm dramatically optimizes matrix processing, enabling the UM442 to track more satellites and shorten the initialization time to 5 seconds.

The MV5-AR inertial sensors are designed for off-highway and military vehicles, marine and mobile robot applications, and the autonomous vehicle market. The rugged, compact sensors use LORD’s fifth-generation high-performance industrial-grade solid-state six-degrees-of-freedom (6-DOF) micro-electromechanical accelerometer and gyro inertial sensor technology. Successfully deployed on ground robots and heavy machinery, applications also include autosteer and terrain compensation; dynamic incline detection (roll, pitch, rotation); vehicle stability and leveling; platform control, alignment and stabilization; operator feedback; and precision navigation. The compact and rugged reinforced housing is fully sealed for immersion and pressure wash. Each sensor is calibrated and temperature compensated.

The ZED-F9P multi-band GNSS module has integrated multi-band real-time kinematic (RTK) technology for machine control, ground robotic vehicles and high-precision unmanned aerial vehicles applications. It measures 22 x 17 x 2.4 millimeters and uses technology from the u‑blox F9 platform to deliver robust high-precision positioning performance in seconds. The ZED-F9P is a mass-market multi-band receiver that concurrently uses GNSS signals from all four GNSS constellations (GPS, GLONASS, Galileo and BeiDou). Combining GNSS signals from multiple frequency bands (L1/L2/L5) and RTK technology lets the ZED‑F9P achieve centimeter-level accuracy in seconds.
