Multi-pathway satellite communication systems and methods
Systems and methods for controlling satellites are provided. In one example embodiment, a computing system can obtain a request for image data. The request can be associated with a priority for acquiring the image data. The computing system can determine an availability of a plurality of satellites to acquire the image data based at least in part on the request. The computing system can select from among a plurality of communication pathways to transmit an image acquisition command to a satellite based at least in part on the request priority. The plurality of communication pathways can include a communication pathway via which the image acquisition command is indirectly communicated to the satellite via a geostationary satellite. The computing system can send the image acquisition command to the selected satellite via the selected communication pathway.
1. A computing system on-board a satellite, the computing system comprising:
one or more processors; and
one or more tangible, non-transitory, computer readable media that collectively store instructions that when executed by the one or more processors cause the computing system to:
receive a query for availability to acquire image data;
determine, based on the query, an availability to acquire the image data;
transmit, to a remote command system or to a geostationary satellite, a signal indicating availability to acquire the image data;
obtain a request for image data, the request comprising at least one of: (i) a location of a target, (ii) an order of imagery acquisition relative to other imaging tasks, (iii) a position of the satellite, (iv) an orientation of the satellite, or (v) a sensor setting;
capture the image data according to the request; and
transmit, to the geostationary satellite, a confirmation signal acknowledging successful completion of the image capture according to the request.
2. The computing system of claim 1 , wherein receiving the query for availability to acquire image data is from the remote command system.
3. The computing system of claim 1 , wherein receiving the query for availability to acquire image data is from the geostationary satellite.
4. The computing system of claim 1 , wherein receiving the query for availability to acquire image data comprises an indication that at least one other satellite received the query.
5. The computing system of claim 1 , wherein the request is associated with a priority for acquiring the image data.
6. The computing system of claim 5 , wherein the instructions when executed by the one or more processors cause the computing system further to:
determine the priority for acquiring the image data.
7. The computing system of claim 5 , wherein the signal indicating the availability to acquire the image data is transmitted to the remote command system or to the geostationary satellite based on the priority.
8. The computing system of claim 1 , wherein the signal indicating the availability to acquire the image data is transmitted to the remote command system.
9. The computing system of claim 1 , wherein the signal indicating the availability to acquire the image data is transmitted to the geostationary satellite.
10. The computing system of claim 1 , wherein capturing the image data according to the request comprises causing at least one of a position or orientation of the satellite to be adjusted.
11. The computing system of claim 1 , wherein obtaining the request for image data comprises receiving:
a first image acquisition track that includes an image acquisition sequence associated with acquiring the image data; and
a second image acquisition track that includes the image acquisition sequence associated with acquiring the image data, wherein the image acquisition sequence is afforded a priority in the second image acquisition track different from a priority in the first image acquisition track.
12. The computing system of claim 11 , wherein the instructions when executed by the one or more processors cause the computing system further to:
receive, from the remote command system, data indicative of the first image acquisition track and the second image acquisition track.
13. The computing system of claim 12 , wherein the priority associated with first image acquisition track is based on at least one of a user request or the target associated with the request.
14. The computing system of claim 11 , wherein the request for image data comprises a command to use an updated communication pathway.
15. The computing system of claim 14 , wherein the confirmation signal is transmitted to the geostationary satellite based on the command to use the updated communication pathway.
16. The computing system of claim 15 , wherein the request for image data comprises an instruction to switch from the first image acquisition track to the second image acquisition track.
17. The computing system of claim 16 , wherein the one or more tangible, non-transitory, computer readable media, when executed by the one or more processors cause the computing system further to:
switch, based on the instruction, from the first image acquisition track to the second image acquisition track.
18. The computing system of claim 17 , wherein the one or more tangible, non-transitory, computer readable media, when executed by the one or more processors cause the computing system further to:
acquire the image data in accordance with the second image acquisition track.
19. A method comprising:
receiving, at a satellite, a query for availability to acquire image data;
determining, based on the query, an availability to acquire the image data;
transmitting, to a remote command system or to a geostationary satellite, a signal indicating availability to acquire the image data;
obtaining a request for image data, the request comprising at least one of: (i) a location of a target, (ii) an order of imagery acquisition relative to other imaging tasks, (iii) a position of the satellite, (iv) an orientation of the satellite, or (v) a sensor setting;
capturing the image data according to the request; and
transmitting, to the geostationary satellite, a confirmation signal acknowledging successful completion of the image capture according to the request.
20. The method of claim 19 , wherein the request is associated with a priority for acquiring the image data.
