Three major equipment groups comprise the subsystem:
- The computer complex provides the computational capability
required to process data (telemetry, tracking, in realtime for support
of orbiting satellites.
- The computer interface equipment provides the interface between
the sensor equipment (e.g., tracking antenna, PCM and FM/FM telemetry
ground stations) and the computer complex.
- The control and display equipment provides centralized control and
monitoring capability for the station.
3.7.1 Computer Complex |
The Univac 1230 mTc computer (figure 3-50) is a general
purpose, stored program processor with active core storage for 49,152 30-bit
words. Memory access is 1.8u sec and memory protection is provided. Internal
parity checks are provided for all data words. Sixteen redundant
input/output (I/O) channels provide service for the two independent
processors. Data may be buffered or stored from externally specified or
indexed memory addresses. A priority interupt system is provided. The
maximum I/O data rate for a single channel is 166,667 words/sec.
The computer complex consists of the following equipment:
- Computer (Univac 1230 mTc)
- Two input/output consoles (Univac 1232)
- Two printers (Anelex 4113)
- Mass storage adapter (Univac 1531)
- Two disk controllers (CDC-3234)
- Four disk drives (CDC-854)
- Two maintenance panels
- SOC II computer control panel
- 400 Hz motor generator system
- Card reader (Mohawk 6002)
- Card reader adapter
The Univac 1232 input/output console (part of Figure 3-51) provides a means
for entering data into the computer using either punched tape or the
alphnumeric keyboard. The console also records output data from the computer
by punching paper tape, by printing on paper, or both simultaneously. Paper
tape is read at 500 frames/sec and punched at 10 frames/sec; The
console printer prints at the rate of 10 characters/sec.
The Anelex 4113 printer (also part of Figure 3-51) prints 300 120-character
lines per minute under control of the computer.
