If a fault stay active in one axis and don't disappear during a RESET, the tracking stops the
operation. For example if the polarisation have a fault, azimuth and elevation stop the tracking
operation.
Technical Specification
Position Encoding with three different interfaces via daughter boards --- Resolver, digital SSI
and potentiometer
Quantization Error --- Resolver 16bit: 0.0055°, SSI 13bit 0.044°, 16bit 0.0055°, 17bit
0.0028°, 19bit 0.0007°
Display Position resolution --- 0.001°
Interface to beacon receivers selectable --- sat-nms LBRX or analog voltage input
Analog voltage input --- 0 to 10V
Option Tracking Accuracy --- Better than 5% of receive 3dB beamwidth (RMS). The encoder
coupling and alignment error should not exceed 0.003° to achieve the specified tracking
accuracy. The influence of antenna structure thermal error is not considered.
