Abstract

In one embodiment, a system for data handling in a distributed communication network includes a data-handling node (DHN) residing at a mission management center (MMC). The MMC manages operations of one or more remote units. The DHN receives a stream of data units from a routing system. The stream of data units includes both stored mission data (SMD) and telemetry data having originated at the remote units. The DHN, in near real time, extracts the telemetry data from the stream of data units, identifies one or more subsystems of the MMC for receiving the extracted telemetry data, and communicates the extracted telemetry data to the identified subsystems of the MMC for processing.

Claims

1. A system for data handling in a distributed communication network, the system comprising:

a data-handling node (DHN) residing at a mission management center (MMC), the MMC managing operations of one or more remote units, the DHN being operable to;

receive a stream of data units from a routing system, the stream of data units comprising both stored mission data (SMD) and telemetry data having originated at the remote units;

in near real time, extract the telemetry data from the stream of data units;

in near real time, identify one or more subsystems of the MMC for receiving the extracted telemetry data; and

in near real time, communicate the extracted telemetry data to the identified subsystems of the MMC for processing.

2. The system of claim 1, wherein the data units comprise virtual channel data units (VCDUs) formatted at least in part according to a Consultative Committee for Space Data Systems (CCSDS) protocol.

3. The system of claim 1, wherein one or more of the remote units are spacecraft.

4. The system of claim 1, wherein SMD having originated at a particular remote unit indicates readings collected at sensors onboard the particular remote unit.

5. The system of claim 1, wherein telemetry data having originated at a particular remote unit indicates a status of each of one or more status points associated with the particular remote unit.

6. The system of claim 1, wherein the telemetry data comprises one or more of real-time telemetry data, playback telemetry data, and stored telemetry data.

7. The system of claim 1, wherein the DHN is further operable to use virtual channel identifiers (VCIDs) in the data units to detect telemetry data for extraction.

8. The system of claim 1, wherein the DHN is further operable to multicast the extracted telemetry data to multiple subsystems of the MMC.

9. The system of claim 1, wherein one or more of the subsystems of the MMC each comprise a satellite telemetry analysis (STA) subsystem, a satellite operations (SO) subsystem, or both.

10. The system of claim 1, wherein one or more of the subsystems are operable to process the extracted telemetry data to generate commands (CMDs) for communication to one or more of the remote units.

11. A method for data handling in a distributed communication network, the method comprising:

at a data-handling node (DHN) residing at a mission management center (MMC), the MCC managing operations of one or more remote units;

receiving a stream of data units from a routing system comprising both stored mission data (SMD) and telemetry data having originated at the remote units;

in near real time, extracting the telemetry data from the stream of data units;

in near real time, identifying one or more subsystems of the MMC for receiving the extracted telemetry data; and

in near real time, communicating the extracted telemetry data to the identified subsystems of the MMC for processing.

12. The method of claim 11, wherein the data units comprise virtual channel data units (VCDUs) formatted at least in part according to a Consultative Committee for Space Data Systems (CCSDS) protocol.

13. The method of claim 11, wherein one or more of the remote units are spacecraft.

14. The method of claim 11, wherein SMD having originated at a particular remote unit indicates readings collected at sensors onboard the particular remote unit.

15. The method of claim 11, wherein telemetry data having originated at a particular remote unit indicates a status of each of one or more status points associated with the particular remote unit.

16. The method of claim 11, wherein the telemetry data comprises one or more of real-time telemetry data, playback telemetry data, and stored telemetry data.

17. The method of claim 11, further comprising, at the DHN, using virtual channel identifiers (VCIDs) in the data units to detect telemetry data for extraction.

18. The method of claim 11, further comprising, at the DHN, multicasting the extracted telemetry data to multiple subsystems of the MMC.

19. The method of claim 11, wherein one or more of the subsystems of the MMC each comprise a satellite telemetry analysis (STA) subsystem, a satellite operations (SO) subsystem, or both.

20. The method of claim 11, wherein one or more of the subsystems are operable to process the extracted telemetry data to generate commands (CMDs) for communication to one or more of the remote units.

21. Software for data handling in a distributed communication network, the software encoded in one or more computer-readable media and when executed operable to:
