Positioning Methods | |
Designate: | Automatically moves the antenna in each axis to one of 99 pre-stored satellite positions. |
Direct Az/El: | Automatically moves the antenna in each axis to the coordinates entered via the front panel. |
Jog: | Manually moves the antenna in each axis in response to front panel controls. |
Peak: | Performs a peaking algorithm on the current target |
Step Track: | Automatically performs peaking algorithm in response to input signal level decreasing below a programmable minimum. |
Program Track: | Automatically moves the antenna in each axis along a sidereal time tagged path. |
External: | Moves the antenna in each axis in response to commands received through the serial port. |
Performance | |
Accuracy: | Antenna pointing accuracy within ten percent of the 3dB beamwidth. |
Tracking Resolution: | > 0.05 degrees with properly specified position sensor. |
Interfaces | |
Reference: | Accepts input of linear, analog signal reference from 0 - 20 VDC. Internal op amp circuit provides pre-scaling of gain and slope of tracking reference signal. Final scaling is provided through software. |
Serial Data: | Accepts RS-232 or RS-485 (4-wire) data for remote monitor and control of all controller functions. |
Front Panel: |
Large Graphic VFD displays antenna position, signal level and operating mode. Keypad provided for user inputs. |
Motor Control: | The rack mounted microprocessor controller is linked to any of SSC's motor control options by serial interface cable. |
Prime Power (ACU): |
90 - 260 VAC, 47 - 63 Hz, single-phase, auto sensing, 65 watts maximum. |
