Control Modes
Manual Jog positioning controls for each axis, including 2-speed AZ and EL control, provides fast and accurate “on-the-fly” positioning. Manual track “jump” mode allows rapid positioning to a set of direct-entry coordinates.
Target Track Automatic positioning via manual command, to any of 50 pre-programmed look-angle sets.
Program Track Automatic sequential positioning to as many as 99 time-tagged pre-programmed look-angle sets over a one week period
Adaptive Step Track Automatic positioning based on optimization of a proportional tracking voltage input. Adaptive nature of Step Track algorithm provides improved performance with inclined orbit satellites.
Enhanced Memory Track Automatic positioning based on a twentyfour hour orbit table built with data from Step Track. This provides the ability to track satellites when the beacon signal is unavailable.
Intelsat Track Automatic tracking to AZ and EL coordinate sets calculated internally from Intelsat 11 parameter coefficients and site latitude and longitude data.
Typical Specifications
Tracking Accuracy Better than 10% of receive beamwidth, RMS, for beamwidths ≥ 0.3° and in applications with orbit inclinations of up to 5° (orbit inclination ≤ 9 x 3 dB beamwidth).
Position Encoding Absolute, single-speed brushless (size-11) resolvers and LSI resolver-todigital conversion IC’s (4 volt, 2500 Hz reference signal).
Position Encoding Resolution 16-bit (.0055°) internal resolution

0.01° front panel display resolution for AZ and EL angles
Absolute Position Encoding Accuracy 0.05° RMS (Standard)
Position Encoding Repeatability 0.01°
