T501 Front-End Processor
The T501 family of products offers innovative solutions for front-end data processing within satellite control centers. Key T501 features include intelligent front-end telemetry processing, formatting, verification of vehicle commands, and control of external devices such as cryptographic equipment. Data is time-correlated using high-precision IRIG signals. The T501 product line Application Programming Interface (API) includes a convenient TCP/IP-based interface, easily integrated into any Telemetry, Tracking, and Control (TT&C) system. A fully-featured web-based interface is also supported.
Telemetry processing functions include format conversion, frame synchronization, and time-tagging. The T501 FEP can be configured to support Time Division Multiplexing (TDM) or Consultative Committee for Space Data Systems (CCSDS) processing, including Reed-Solomon decoding and VCDU/packet processing, bit synchronization, and data recording/playback. Command processing functions include conversion to an uplink encryptor’s ternary or binary formats, fill command generation, time release, block commanding, and command echo checking. The T501 can also be used to generate simulated telemetry streams for loopback testing. The T501 provides a common, consistent network-based resource for monitoring and control of encryption and decryption equipment.
