Abstract

Systems, methods, and software described herein provide enhancements for deploying software payloads to satellite devices, such as when a satellite device is in orbit. In one example, a satellite device includes a communication interface configured to receive one or more software payloads, and a storage system configured to store the one or more software payloads on the satellite device. The satellite device also includes a payload execution system configured to execute the one or more software payloads as one or more virtual nodes.

Claims

1. A satellite device, comprising:

communication interface configured to receive one or more software payloads;

a storage system configured to store the one or more software payloads on the satellite device; and

a payload execution system configured to execute the one or more software payloads as one or more virtual nodes.

2. The satellite device of claim 1, comprising:

the payload execution system comprising a hypervisor system configured to manage at least execution resources of the payload execution system among the one or more software payloads when executing the one or more virtual nodes.

3. The satellite device of claim 1, wherein the one or more virtual nodes each comprise at least one among a virtual container, virtual application, and a virtual machine.

4. The satellite device of claim 1, comprising:

the communication interface configured to receive the one or more software payloads transferred by at least one among a ground communication system that deploys the one or more software payloads to the satellite device in orbit, another satellite device, or another device.

5. The satellite device of claim 1, comprising:

the payload execution system configured to provide one or more first processing cores of the payload execution system to a first virtual node and provide one or more second processing cores of the payload execution system to a second virtual node.

6. The satellite device of claim 1, comprising:

the payload execution system configured to execute the one or more software payloads as the one or more virtual nodes on the satellite device according to at least a resource schedule that indicates a timewise allocation of the one or more virtual nodes to on-board resources of the satellite device.

7. The satellite device of claim 1, comprising:

one or more logistical control elements comprising one or more among satellite position control elements, inertial control elements, orbital control elements, power control elements, and thermal control elements; and

wherein the one or more software payloads execute independently of the one or more logistical control elements of the satellite device.

8. The satellite device of claim 1, comprising:

the payload execution system further configured to transfer over the communication interface state information related to execution of the one or more virtual nodes.

9. The satellite device of claim 1, comprising:

the payload execution system further configured to;

maintain state information in related to operation of the one or more virtual nodes in the storage system or in one or more memory spaces;

detect one or more failures related to the operation of the one or more virtual nodes; and

responsive to the one or more failures, initiate at least one virtual node to continue one or more activities based at least on the state information of the one or more virtual nodes that experience the failure.

10. A method of operating a satellite device, comprising:

in a communication interface, receiving one or more software payloads;

in a storage system, storing the one or more software payloads on the satellite device; and

in a payload execution system, executing the one or more software payloads as one or more virtual nodes.

11. The method of claim 10, wherein the payload execution system comprises a hypervisor system;

and comprising;

in the hypervisor system, managing at least execution resources of the payload execution system among the one or more software payloads when executing the one or more virtual nodes.

12. The method of claim 10, wherein the one or more virtual nodes each comprise at least one among a virtual container, virtual application, and a virtual machine.

13. The method of claim 10, further comprising:

in the communication interface receiving the one or more software payloads transferred by at least one among a ground communication system that deploys the one or more software payloads to the satellite device in orbit, another satellite device, or another device.

14. The method of claim 10, further comprising:

in the payload execution system, providing one or more first processing cores of the payload execution system to a first virtual node and providing one or more second processing cores of the payload execution system to a second virtual node.

15. The method of claim 10, further comprising:

in the payload execution system, executing the one or more software payloads as the one or more virtual nodes on the satellite device according to at least a resource schedule that indicates a timewise allocation of the one or more virtual nodes to on-board resources of the satellite device.
