Azimuth accuracies stated in 3.6.1.1.9.1, 3.6.1.1.9.2, and
3.6.1.1.9.3 apply to Pointing Device Grid and Geodetic Azimuths
assuming the DRU has been accurately aligned to the pointing
device. Vehicle Grid and Geodetic Azimuths are approximations
without accuracy specifications.
The following is a summary of accuracy requirements.
