For the technical solution described in fig. 1, in some possible embodiments, the planning and executing the multi-star cooperative task based on the inter-star packet interaction protocol according to a set timing rule includes:
the planning star starts from T0-30 minutes, and the cooperative scheduling data packet is sent to each member star every 1 minute; transmitting the cooperative scheduling data packet to each member star every 3 seconds after T0-3 minutes; starting a cooperative task until the time T0;
the member star receives the cooperative scheduling data packet sent by the planning star, and sets a working state of the member star so as to have imaging conditions at the moment T0 and start an electromagnetic signal detection load; wherein, each member star sends the state feedback data packet to the planning star once every 3 seconds from the time of T0-3 minutes; sending an inter-satellite guiding data packet to the planning satellite every 8-40 seconds, wherein each inter-satellite guiding data packet contains at most 10 target information;
the member star stops sending the inter-star data packet to the planning star at the time of T0+dT, and carries out load shutdown and attitude-to-day orientation state recovery operation;
after the planning star cooperates with the task T0+dT, executing a stand-alone shutdown instruction chain except a data server, and executing a satellite-ground data transmission task of ground program control, and after the execution is finished, executing a sun-oriented operation;
wherein T0 represents the starting time of the collaborative task; dT represents the duration of the collaborative task.
Specifically, as shown in fig. 3, after the start of the multi-star task cooperation, by defining the transmission time of the cooperative scheduling data packet, the state feedback data packet, and the inter-star guidance data packet, the inter-star information can be efficiently and accurately interacted. In the specific implementation process, a resident task center point and a resident task triggering effective radius are preset on the ground to jointly define a plurality of ground circular areas, when a top window exists on the circular areas by a star cluster understar point, basic conditions for starting a cooperative task of the areas are considered to be provided, meanwhile, the solar altitude in the period needs to meet the minimum solar altitude requirement, T0 and dT of a cooperative element task are determined according to window time and area radius, wherein T0 is the starting moment of the multi-star cooperative task, and dT is the cooperative duration.
In the implementation process, the situation that a low-speed network between the oriented satellites is possibly invisible is considered, when the planning star starts to send an adjacent cooperative task to each member star in T0-30 minutes, the same cooperative scheduling data packet is sent to each member star every 1 minute, and the frequency of sending the cooperative scheduling data packet is increased to every 3 seconds from T0-3 minutes until the stable interaction state after T0 is entered. Before time T0, each star starts its own load to have a cooperative condition.
Meanwhile, after the member star receives the cooperative scheduling data packet sent by the planning star, the member star sets the working state of the member star to realize the imaging condition at the time T0 and start the electromagnetic signal detection load. It should be noted that, the status feedback data packet of each member star starts to be sent to the planning star in the period of T0-3 minutes, and is sent once every 3 seconds, so that each member star has the capability of on-orbit adjustment.
In addition, the inter-satellite guiding data packet is sent to the planning satellite every 8-40 seconds, and the sending frequency can be adjusted every 8 seconds according to actual conditions in the actual implementation process, and each inter-satellite guiding data packet contains 10 target information at most. The inter-satellite guidance data packet preferably transmits the electromagnetic signal detection target information of wide area discovery, and then the electromagnetic signal detection target information of single wide area discovery.
And finally, stopping the transmission of inter-satellite data at the time of receiving T0+dT of the cooperative task by each member satellite, and executing the on-satellite state recovery operations such as load shutdown, attitude versus day orientation and the like. After the planning star sends the coordinated task T0+dT, the single machine shutdown instruction chain except the data server is firstly executed, the satellite-ground data transmission task of ground program control is immediately executed, and after the execution is finished, the sun-oriented recovery operation is executed.
