Abstract:	Many positioning applications today require not only exact coordinates of a particular point, but complete 6D accurate positioning of a platform. Here 6D refers to 3D cm level position plus 3D sub-degree attitude (heading, pitch, and roll angles). This paper describes a GNSS-based Precise Platform Positioning solution for position + heading applications implemented with the MB-One OEM board from Trimble Integrated Technologies. No additional sensors or data links are needed to achieve centimeter-level position accuracy and sub-degree orientation for land applications. The MB-One board described herein employs a hardware design that translates into a compact form factor with significant size/cost/power optimization. The paper further touches on the details associated with the receiver firmware and solutions to achieve simultaneously the following modes of operation: • Precise Point Positioning (PPP) with L-band correcting data using Trimble RTX technology [1] • Precise attitude/heading using Ashtech 3DF technology [2] It further demonstrates Trimble CenterPoint RTX performance in terms of steady state accuracy, convergence time, stability and continuity with interruptions. Also, it shows heading performance as a function of GNSS constellation available and the quality of the antenna installed (high end and low end). As an extended application, we show how complete 6D positioning (3D position + heading/pitch/roll) can be achieved with two tightly integrated MB-One boards.
