Abstract

The disclosure provides a three-dimensional flight path planning method for super-pressure balloons in stratosphere, which comprises the following steps that according to expected staying target positions decomposed to the super-pressure balloons, a path space which includes the expected staying positions and a range is chosen, and cubic grid generation is carried out; a Rubik's cube search methodis utilized, through prediction on environmental big data changes by means of an estimation algorithm, the probability of arrival at each adjacent cubic grid after a time interval is calculated; on the basis of a Markov decision process, path planning is carried out in the whole path space, actual control is carried out according to the path planning, and reward and punishment are carried out according to the rolling accumulation of actual control results and path planning results to determine subsequent planning and control; and according to the actual control results, environmental big dataare enhanced and updated. The three-dimensional flight path planning method for the super-pressure balloons in the stratosphere disclosed by the disclosure realizes long-time reliable staying by controlling staying and load direction, meeting the requirement of application in a spatial information network.

Description

technical field [0001] The present disclosure relates to the technical field of spatial information network, in particular to a method for planning a three-dimensional track of a stratospheric overpressure balloon. Background technique [0002] The space information network is a network system that acquires, transmits and processes space information in real time with space platforms (such as geostationary satellites or medium and low orbit satellites / constellations, near-space aerostats or unmanned aerial vehicles, etc.) as carriers. As an important national infrastructure, the space information network can also support high dynamics of earth observation, broadband real-time transmission, and ultra-long-range deep space exploration while serving major applications such as ocean navigation, emergency rescue, navigation and positioning, air transportation, and aerospace measurement and control. , Reliable transmission with long delay, so as to expand human science, culture, an...
