Unicore has launched its next-generation quad-system GNSS module, the UM482.

The UM482 is a multi-frequency high-precision heading module with a small footprint, supporting the satellite signals BDS B1/B2, GPS L1/L2, GLONASS L1/L2, Galileo E1/ E5b and SBAS.

The module is designed for applications such as robotics, drones, intelligent drives and mechanical control.

Key features of the UM482 module:

  • Tiny 30 × 40 millimeter footprint, all-system multi-frequency high-precision heading module, surface-mount (SMD) packaging
  • Supports GPS L1/L2, BDS B1/B2, GLONASS L1/ L2, Galileo E1/E5b
  • 1-cm RTK positioning accuracy and 0.2-degree heading accuracy with 1-m baseline
  • Dual antenna input with support of antenna signal detection
  • Supporting simultaneous output of heading and positioning, 20-Hz data output rate
  • Adaptive recognition of RTCM input data format
  • On-board micro-electro-mechanical system (MEMS) integrated navigation

The UM482 GNSS RTK module adopts Unicore’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, the company said. It can involve all satellites from GPS, BDS, GLONASS and Galileo in RTK and heading processing, shorten RTK and heading initialization time to 5 seconds and significantly improve the reliability and accuracy of RTK and heading.

Furthermore, the UM482 integrates the onboard MEMS chip and U-Fusion integrated navigation algorithm, resulting in optimized continuity and reliability of accurate heading and positioning output in tough environments such as city canyons, tunnels and overpasses. Inputs of odometer and external higher performance inertial components are supported.

The UM482, along with all the UM and UB family of receivers, will be on display at booth B4018 for the duration of the Intergeo 2017 trade show, which takes place Sept. 26-28 at Berlin Exhibition Center, Berlin, Germany.
