Description
Trimble GEDO IMU
The Trimble GEDO IMU is a highly accurate sensor with inertial measurement technology, optimized for the use with Trimble GEDO track measurement systems.
GEDO systems equipped with this sensor allow highly productive and accurate track as-built surveys. By combining it with other sensors, the Trimble GEDO IMU can be used for a wide range of track surveying tasks. The IMU measurements are largely weather independent.
