Workshop 2018
Andria Bilich - 6-axis robot for absolute antenna calibration at the US National Geodetic Survey - October 29, 2018 • 547 Views
Beginning in 2019, the US National Geodetic Survey (NGS) will be restarting its absolute antenna calibration program with a new 6-axis robotic arm. Initial calibrations will be GPS L1+L2+L5, but we will incrementally add in capability for full GNSS calibrations. In this presentation, we will show preliminary results from the new system and will compare those results to IGS type mean calibrations. We will also discuss upcoming collaboration with the National Institute of Standards and Technology (NIST), which operates an indoor antenna calibration test range using a robotic positioner. Planned collaboration with NIST includes comparing calibration results from NIST and NGS, and updating the NGS robot’s kinematic model to improve the robot positioning accuracy.
