Abstract

Systems, methods, and software described herein provide enhancements for spaceborne and airborne computing platforms. In one example, an airborne computing platform includes a plurality of airborne devices, with one or more of the airborne devices comprising specialized roles defined by at least one among software elements and hardware elements targeted to the specialized roles. Individual ones of the airborne devices are configured to identify tasks to be serviced using one or more of the specialized roles, determine one or more target devices to handle the tasks based at least in part on attributes of the target devices, and transfer at least task instructions for delivery to the target devices for performing the tasks.

identify tasks to be serviced using one or more of the specialized roles;

based at least in part on the attribute scoring metrics, determine one or more target aircraft that satisfy the one or more of the specialized roles to handle the tasks; and

transfer at least task instructions for delivery to the one or more target aircraft for performing the tasks using at least one among the presently provisioned software elements and hardware elements associated with the one or more of the specialized roles.

2. The airborne platform of claim 1, wherein the attribute scoring metrics are stored in a data structure relating identities of the one or more aircraft to competency ratings associated with the specialized roles.

4. The airborne platform of claim 1, wherein the task instructions comprise state information related to execution of virtual nodes by the plurality of aircraft, and comprising:

the one or more target aircraft comprising virtualized execution systems configured to receive the state information and execute one or more software applications as virtual nodes according to the state information to perform the task instructions using the at least one among the presently provisioned software elements and hardware elements associated with the one or more of the specialized roles.

5. The airborne platform of claim 1, comprising:

the individual ones of the aircraft further configured to transfer the task instructions through one or more peer aircraft to reach the one or more target aircraft; and

responsive to receiving the task instructions, each receiving peer aircraft is configured to evaluate received task instructions against one or more specialized role attributes of the receiving peer aircraft to determine if the receiving peer aircraft has a corresponding specialized role to act in accordance with the task instructions or should instead transfer the task instructions to at least one further peer device.

6. The airborne platform of claim 1, wherein the tasks to be serviced using the one or more of the specialized roles comprise imaging tasks for a specialized role to capture image data corresponding to an underlying geographic region;

and comprising;

based at least on receipt of the task instructions, a first aircraft configured to determine that the first aircraft has the specialized role to capture the image data, capture the image data corresponding to the underlying geographic region, and transfer the image data for receipt by a second aircraft.

7. The airborne platform of claim 6, wherein the second aircraft corresponds to a specialized role of graphics processing, and comprising:

based at least on receipt of the image data, the second aircraft configured to determine that the second aircraft has the specialized role of graphics processing, and process the image data to determine processed image data according to at least further task instructions comprising the image data.

8. The airborne platform of claim 7, comprising:

the second aircraft configured to transfer the processed image data for delivery to a destination through at least a peer aircraft having a specialized role corresponding to communication routing.

9. The airborne platform of claim 1, wherein the tasks to be serviced using the one or more specialized roles comprise communication routing;

and comprising;

a first aircraft having a specialized role of communication routing configured to transfer data associated with the tasks for receipt by a communication system based at least on receipt of the task instructions and data from another aircraft.

10. A method of operating an airborne platform, the method comprising:

defining specialized roles among a plurality of aircraft, wherein the specialized roles are defined based at least on presently provisioned software elements and hardware elements that vary among the plurality of aircraft;

maintaining attribute scoring metrics that rate one or more aircraft in competency among at least a portion of the specialized roles;

identifying tasks to be serviced using one or more of the specialized roles;

based at least in part on the attribute scoring metrics, determining one or more target aircraft that satisfy the one or more of the specialized roles to handle the tasks; and

transferring at least task instructions for delivery to the one or more target aircraft for performing the tasks using at least one among the presently provisioned software elements and hardware elements associated with the one or more of the specialized roles.

11. The method of claim 10, wherein the attribute scoring metrics are stored in a data structure relating identities of the one or more aircraft to competency ratings associated with the specialized roles.

12. The method of claim 10, wherein the specialized roles comprise one or more of a data processing role, a data storage role, an imaging role, a communication routing role, and a virtualized software execution role.

13. The method of claim 10, wherein the task instructions comprise state information related to execution of virtual nodes by virtualized execution systems of the aircraft, and comprising:
