*With the retrofit option, the 8200 ACU is compatible with legacy drive-cabinet interfaces and position-feedback devices such as absolute rotary optical encoders, standard single-speed brushless size 11 resolvers, and two-speed brushless size 20 resolvers.


  • Touchscreen controls for all operations
  • Efficient, intuitive graphical user interface
  • Hardware jog buttons with LED indicators
  • Data and parameters secured in nonvolatile storage
  • Innovative setup wizard eases installation
  • Secure TeamViewer integration for remote and shared ACU operation
  • Field-proven in critical applications

Modes of Operation

Step TrackAdvanced algorithm for periodic or signal-level-triggered scans to peak the signal level
Predictive TrackTracks targets based on an orbital model developed from prior Step Track data points
NORAD TLEAutomated tracking based on NORAD two-line element sets
Intelsat (IESS-412)Tracking derived from Intelsat 11-element parameter sets
TLE with SteptrackTrack using TLE as a base model but add periodic Step Tracks to correct for offsets over time
IESS-412 with SteptrackTracking with Intelsat model, with added Step Track to correct for offsets over time
Manual JogDedicated front-panel antenna jog controls
Move to LongitudePoints the antenna to AZ and EL angles determined by the longitudinal orbital slot
Move to Look AnglesPoints the antenna to user-supplied AZ, EL and POL angles
