Embodiment 1

[0067] Such as figure 1 As shown, a satellite observation system includes:

[0068] A satellite orbit prediction module for carrying satellite observation models, calculating satellite positions, and predicting satellite transit time,

[0069] A task management release module for notifying relevant observation sites to conduct satellite coordinated observation and select observation satellites,

[0070] A site management module for managing observation site information.

Embodiment 2

[0072] Such as figure 2 As shown, this embodiment is a method for coordinated observation of high-resolution satellites based on the software part of Embodiment 1, including the following steps:

[0073] S1. Establish a satellite observation model. The satellite observation model includes: an orbit calculation model, a satellite sub-satellite point longitude and latitude calculation model, and a satellite coverage area model, wherein: the orbit calculation model adopts Kepler's classical solution model calculation standard for basic problems Called the Kepler orbit, the satellite sub-satellite point latitude and longitude calculation model calculates the sub-satellite point position through the Kepler equation, and the satellite coverage area model determines the coverage area by contacting the ground,

[0074] Among them, the orbit calculation model refers to the classic solution model of Kepler's basic problems as:

Abstract

The invention provides a collaborative observation method based on high-resolution series satellites. The collaborative observation method comprises the following steps that: S1, a satellite observation model is established; S2, an observed high-score series satellite is selected by a task management publishing module; S3, a satellite orbit forecasting module analyzes, simulates and predicts remote sensing satellite area coverage, and predicts the time when the satellite passes through the site in combination with an observation product corresponding to the observed high-resolution satellite; and S4, the task issuing module notifies related observation stations through mails or short messages, and collaborative observation is carried out after confirmation of the stations. The method solves the problems of poor observation effect and untimely collaboration of a collaborative observation technology for high-resolution series satellites, and has the advantage of laying a foundation for authenticity inspection of 45 common products.

Description

technical field [0001] The invention relates to the technical field of satellite observation, in particular to a collaborative observation method based on high-resolution satellites. Background technique [0002] The China Gaofen series satellites are a series of high-resolution earth observation satellites planned by the "High-resolution Project". It is one of the 16 major projects identified in the "National Medium and Long-Term Science and Technology Development Plan (2006-2020)". The special system was approved by the State Council to start implementation in 2010. [0003] As of now (2020-10), the Gaofen series has developed from Gaofen No. 1 to Gaofen No. 13, including: "Gaofen No. 1", "Gaofen No. 2", "Gaofen No. 6", "Gaofen-8", "Gaofen-11" and "Gaofen-13" are optical remote sensing satellites; "Gaofen-3", "Gaofen-10" and "Gaofen-12" are microwave Remote sensing satellite; "Gaofen-4" is an optical satellite in geosynchronous orbit, with visible light and multi-spectr...
