combinations of software modules, operator control, and fixed microprocessor hardware logic. Network control
and status functions are provided on the NCU front panel along with monitor test and fault isolation functions.
The AJ/CM replaces the RT-1287 nonsecure FM orderwire. It operates as an orderwire between the NT in
addition to its communications function. In a jammed environment, the AJ/CM equipment provides the antenna
tracking signal instead of normal communications tracking.
LEARNING EVENT 14: DATA ENTRY
1. The SAMS element of the AN/MSQ-114 and the AN/FSQ-124 provides the data base for planning GMF
resources. The SAMS also provides the monitor facilities for managing the GMFSC network. The SAMS
supports the GMF controller in translating satellite communications (SATCOM) requirements into channel
capacities, time schedules, transmitter power, RF frequency assignments, and modes of operation. The SAMS
monitors and measures the technical performance of deployed GMF ground terminals. This allows the mission
to be accomplished with a minimum assignment of available RF power and bandwidth. It also helps determine
compliance of GMF ground terminal with assignments.
2. Network management is done by the SAMS software which consists of various resource planning,
measuring calculating, and report generating programs. These programs present the GMF controller with a
real-time description of the satellite downlink.
3. The major parameters to be measured and calculated include C/KT density (analog and digital signals
received by the AN/MSQ-114 and AN/FSQ-124 terminals), operating noise temperature, and percentage of
satellite power usage. Alarm conditions and statistical data are also presented to the controller as conditions
dictate and/or as required. A real-time operating system controls the SAMS software modules and data bases.
4. The SAMS uses all of the hardware, under control of computer programs, to perform the following required
functions:
Plan GMF links.
Monitor the GMF downlink spectrum.
Produce summary reports.
Interact with the operator through a user friendly man-machine interface.
Maintain a large database for use in the planning and monitoring function.
Manage all operations.
