2.1.1. Azimuth Assembly (Unit 2 A1 A1)
The Azimuth Assembly is a sealed unit. There are no “field serviceable” components in the
Azimuth unit. The sealed Slip Ring Assembly extends into the Elevation Assembly and the top
of the Fiber Optic Rotary Joint is accessible from the maintenance port on the Elevation
Assembly. The mechanical components are virtually “maintenance free,” with the Actuator Unit
boasting an MTBF (Mean Time Between Failure) of more than 180,000 operational hours (> 20
years).
