OXTS products don’t rely on just one measurement principle.
By using the measurements from a six-axis inertial measurement unit as well as a GNSS receiver, they can calculate and maintain position even when passing through a deep cutting or under a bridge. 250Hz update rates mean that the system can provide a constant picture of its orientation for video and lidar systems.
Rail Survey
Getting consistent data out of a GNSS-only product is very challenging when working in a rail environment.
Frequent obstructions can mean drop-outs in data, multipath from reflections, and poor satellite visibility. These conditions mean that it is not possible to collect data, and repeated tests would need to be carried out.
