Problems solved by technology

[0003] At present, in satellite observation activities at home and abroad, satellite on-orbit activities are planned in advance by the ground station, and then uploaded to the satellite through a suitable uplink for off-line execution. This method requires sufficient satellite-ground communication time and Relatively stable operating environment, due to frequent star-earth interaction, the operating cost of this method is relatively high

Embodiment Construction

[0013] The specific implementation of the on-board autonomous distributed task scheduling method provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Please refer to figure 1 , is a schematic flow chart of the on-board autonomous distributed task scheduling.

[0015] In an embodiment of the present invention, the on-board autonomous distributed task scheduling method includes:

[0016] First, step S1 is executed to upload the observation task sequence to the satellite, that is, to complete the input of the task target. The observation task sequence includes the observation target coordinate point sequence value of the observation task that needs to be scheduled and planned.

[0017] The observation task is an observation task that needs to be scheduled and planned by the satellite within a certain period of time in the future. The future period of time may be one month, six months, or one year, etc., the ...

Abstract

The invention discloses an onboard autonomous distributed task scheduling method. The method comprises steps: an observation task sequence is uploaded to a satellite, wherein the observation task sequence comprises observation target coordinate point sequence values for observation tasks in need of scheduling planning; according to satellite body orbit parameters and the observation target coordinate point sequence values, a visual time window between the satellite and each target position is calculated; and with the visual time window between the satellite and the target position as an input parameter, task scheduling is carried out by a main satellite, the scheduling task is divided to a plurality of sub scheduling tasks, the main satellite transmits the sub scheduling task sequence to a concomitant satellite for calculation, a scheduling result is returned to the main satellite, and a general task scheduling result is formed. The above method can realize the satellite onboard autonomous task scheduling function, and the task scheduling efficiency is improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an on-board autonomous distributed task scheduling method. Background technique [0002] Mission planning plays a key role in the entire satellite application process. It mainly solves the effective allocation and planning of satellite resources and completes the observation tasks submitted by users to the maximum extent. It is one of the main factors affecting the efficiency of satellite use. [0003] At present, in satellite observation activities at home and abroad, satellite on-orbit activities are planned in advance by the ground station, and then uploaded to the satellite through a suitable uplink for off-line execution. This method requires sufficient satellite-ground communication time and Relatively stable operating environment, due to the frequent interaction between the star and the ground, the operating cost of this method is relatively high. [0004] Therefore, i...
