Problems solved by technology

[0004] (1) The joint planning of imaging and data transmission is not well considered, that is, satellite imaging and data transmission are planned separately, and imaging and data transmission are two highly coupled actions, and separate planning cannot carry out optimization from a global perspective Computing and imaging are the prerequisites for data transmission. Timely data transmission can release satellite storage, which affects imaging planning. Moreover, independent planning cannot compress time from the perspective of the entire process, so that tasks can be completed as soon as possible. In addition, separate planning requires a lot of manpower Ancillary processing, non-automated planning services;
[0005] (2) Data transmission planning does not consider the situation of data relay. With the development of aerospace technology, it is already feasible to use data relay satellites for data relay. However, the current planning technology does not take into account the situation of data relay and has not fully utilized Space resources enable data to be transmitted back to the ground as early as possible to reduce user waiting time;
[0006] (3) The solution algorithm is a single solution algorithm, and the advantages of multiple algorithms cannot be absorbed in a single solution process

Abstract

The invention discloses a joint task planning method for satellite imaging and transmission. The joint mission planning method is characterized by comprising the steps of 1, obtaining a two-dimensional imaging data sheet and a two-dimensional transmission data sheet; and 2, obtaining a planning result by using multi-algorithm hybrid iterative solution. According to the joint task planning method, the planning and computing can be carried out from the satellite imaging and transmission integrated global prospect, so that a more optimized automatic planning service can be provided.

Description

technical field [0001] The invention belongs to the technical field of satellite mission planning, and in particular relates to a satellite imaging and transmission integrated mission planning method with data relay. Background technique [0002] A satellite is a machine manufactured by humans and launched into space. It flies in a certain orbit and revolves around the earth. Imaging satellites can image the areas of the earth that they pass through and cover through the onboard imaging sensors, and transmit the images back to the ground station for use by ground users. At present, imaging satellites play an important role in many application fields such as national defense and people's livelihood, such as environmental monitoring, land survey, target search, emergency rescue, etc. Satellite mission planning is an important link in the daily management and control of satellites. It is used to deal with users' competition for satellite resources, so that scarce satellite res...
