Abstract

The disclosed technology relates to systems and methods for tasking satellite constellations. A method is disclosed herein for receiving, from a resource database of a satellite control system, knowledge data corresponding to a plurality of components associated with a satellite constellation communications system. The plurality of components can include one or more satellites associated with a constellation. The method includes processing the knowledge data according to at least one received mission objective. Processing the knowledge data can include determining a status of at least one satellite in the constellation. The method includes scheduling the satellite control system based at least in part on the received mission objective and the processed knowledge data; initiating communication with the at least one satellite in the constellation according to the scheduling; receiving updated status information for at least one component of the plurality of components; and storing, in the resource database, the updated status information.

Claims

1. A computer-implemented method comprising:

receiving, from a terrestrial resource database of a satellite control system, knowledge data corresponding to a plurality of components associated with a satellite constellation communications system, wherein the plurality of components comprises at least one ground station and two or more satellites associated with a constellation, wherein the knowledge data comprises regulatory limitations on what area of the sky the at least one ground station can cover;

processing the knowledge data according to at least one received mission objective, wherein processing the knowledge data comprises determining, by one or more processors, a capability of each of the plurality of components to collectively achieve the mission objective;

preparing, based on the processing, a mission queue for the plurality of components, wherein the preparing the mission queue comprises determining constraints and priorities of the plurality of components associated with the satellite constellation;

commanding at least one of the plurality of components to take a specified action based at least in part on the mission queue;

initiating, by the at least one ground station, communication with the at least one satellite in the constellation according to the mission queue;

receiving updated status information comprising a status change for at least one component of the plurality of components; and

storing, in the resource database, the updated status information.

2. The method of claim 1, wherein processing the knowledge data is performed by a metadata service associated with the satellite control system.

3. The method of claim 1, wherein processing the knowledge data further comprises determining a status of at least one communication link of the satellite constellation communications system, wherein the at least one communication link is capable of communication with the at least one satellite in the constellation according to the mission objective or the mission queue, and wherein determining the status comprises determining a mission capability of the at least one satellite in the constellation.

4. The method of claim 3, wherein the at least one communication link comprises the least one ground station.

5. The method of claim 1, further comprising dynamically revising, by the one or more processors, the mission queue, based on the updated status information.

6. The method of claim 1, wherein initiating, by the least one ground station, comprises configuring a software defined radio associated with the at least one ground station.

7. The method of claim 1, wherein initiating, by the least one ground station, comprises configuring a software defined radio associated with the at least satellite.

8. The method of claim 1, further comprising generating, by the one or more processors, translated commands for communication with at least one of the plurality of components associated with the satellite constellation communications system, wherein generating the translated commands comprises translating high-level commands into a sequence of low-level commands needed for a particular task.

9. The method of claim 1, wherein the constellation comprises at least one CubeSat.

10. The method of claim 1, wherein the satellite constellation communications system comprises one or more of a satellite-based Automatic Identification System (S-AIS) and a GPS Radio Occultation (GPS-RO) system.

11. A satellite constellation communications system comprising:

a central command and control system configured for communication with at least one satellite associated with a constellation, and by at least one ground station;

at least one memory for storing data and computer-executable instructions, the at least one memory comprising a resource database configured for storing knowledge data corresponding to a plurality of components associated with the satellite constellation communications system, wherein the plurality of components comprises the at least one satellite associated with the constellation;

at least one processors in communication with the at least one memory, wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to;

receive, from the resource database, the knowledge data, wherein the knowledge data comprises regulatory limitations on what area of the sky the at least one ground station can cover;

process the knowledge data according to at least one received mission objective, wherein processing the knowledge data comprises determining a capability of each of the plurality of components to collective achieve the mission objective;

prepare, based on the processing of the knowledge data, a mission queue for the plurality of components, wherein the preparing the mission queue comprises determining constraints and priorities of the plurality of components associated with the satellite constellation;

command at least one of the plurality of components to take a specified action based at least in part on the mission queue;

initiate, by the at least one ground station, communication with the at least one satellite in the constellation according to the mission queue;

receive updated status information comprising a status change for at least one component of the plurality of components; and

store, in the resource database, the updated status information.

12. The system of claim 11, further comprising a metadata service, wherein processing the knowledge data is performed by the metadata service.

13. The system of claim 11, wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to determine a status of at least one communication link of the satellite constellation communications system, wherein the at least one communication link is capable of communication with the at least one satellite in the constellation according to the mission objective or the mission queue, and wherein determining the status comprises determining a mission capability of the at least one satellite in the constellation.

14. The system of claim 13, wherein the at least one communication link comprises the least one ground station.

15. The system of claim 11, wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to dynamically revise the mission queue based on the updated status information.

16. The system of claim 11, wherein the at least one ground station comprises a software defined radio, and wherein the initiating comprises configuring the software defined radio at the at least one ground station.

17. The system of claim 11, wherein the at least one satellite comprises a software defined radio, and wherein the initiating comprises configuring the software defined radio at the at least one satellite.

18. The system of claim 11, wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to translate at least one command for communication with at least one of the plurality of components associated with the satellite constellation communications system, wherein generating the translated commands comprises translating high-level commands into a sequence of low-level commands needed for a particular task.

19. The system of claim 11, wherein the constellation comprises at least one CubeSat.
