Abstract: Systems and software interfaces that provides a local graphical-user-interface (GUI) to a remotely located spectrum analyzer. The spectrum analyzer receives carrier signals transmitted from an orbiting spacecraft. The present systems and software interface enable a user, such as a communications technician or engineer, to efficiently and effectively retrieve information from the remotely located spectrum analyzer. Software comprising the software interface is disposed on a client computer that is coupled by way of a network and server computer to the spectrum analyzer. The software remotely controls the spectrum analyzer to locally process and analyze carrier signals on the client computer that were received by the spectrum analyzer.

Abstract: Systems and methods that monitor part-time transponder usage in real time. A satellite carries one or more part-time usage transponders and a ground station communicates with the transponders. A satellite receiver at the ground station processes transponder signals to output a baseband video signal when present and a noise signal when the video signal is not present. An integrated receiver-decoder at the ground station processes the transponder signal to output an analog video signals comprising constant video black line, synchronization, tip and color burst signals, when no signal is present at the input thereof.

Abstract: A system and method for providing remote viewing of satellite transponder plots. The system and method piovides for remote viewing of transponder plots derived from transponders located on a satellite that communicate with ground terminals having an antenna. The system comprises an antenna switch for receiving transponder signals from the antenna. A spectrum analyzer is coupled to the antenna switch for generating transponder plots. An equipment control computer is coupled to the antenna switch and the spectrum analyzer that selectively routes signals from the antenna switch to the spectrum analyzer and routes transponder plots generated by the spectrum analyzer. A server computer is coupled to the equipment control computer that stores the transponder plots generated by the spectrum analyzer that are routed by the equipment control computer.
