Trimble MB-TWO

RTK/ PPP heading in a single OEM module

The Trimble MB-Two is the successor to the Trimble MB-One OEM receiver module. The MB-two maintains the identical form-factor as its predecessor and offers customers a drop-in replacement to utilize the latest GNSS design innovations. Versatile, powerful, compact and smart, the Trimble MB-Two provides faster dualfrequency-based heading acquisition and an improved RTK/PPP positioning engine with multiple GNSS signals. In addition, two MB-Two modules can be easily connected to each other to build a Precise Platform Positioning module (no firmware upgrade required), utilizing up to four dual-band GNSS antennas for multisensory raw data output, precise position and attitude simultaneously. The MB-Two allows a wide range of optionupgradable GNSS configurations from single antenna/frequency (GPS) to dual antenna/frequency (GPS, QZSS, GLONASS, Beidou, Galileo). Ashtech’s patented Z-Blade technology drives a powerful GNSS agnostic engine allowing MB-Two to use any single GNSS system for positioning (or any combination of them) without relying on GPS. The GNSS engine utilizes over-the-air satellite corrections via embedded L-band hardware to achieve centimeter/decimeter level accuracy with PPP Trimble™ RTX corrections removing the dedicated base station/Network and communication link.


Dual atenna / sensor

  • Heading + Pitch/Roll
  • Accurate/Fast Heading using dualfrequency multi-GNSS algorithms
  • Dual GNSS sensor raw data with common clock
  • Single board for RTK/PPP and heading simultaneously

Powerfull RTK engine

The MB-Two has a powerful RTK engine that delivers centimeter-level accuracy for systems using corrections from a local base or an RTK network. It also features RTK against a moving base for relative positioning. The network RTK capabilities include third-party network corrections such as VRS, FKP, and MAC. When two or more alternative RTK correcting data are available, MB-Two runs the Ashtech Hot Standby RTK algorithm allowing it to use them simultaneously in the positioning process
