Abstract

The invention discloses an imaging satellite task planning method considering meteorological information. The method comprises the following steps of loading meteorological data information in a future predetermined time; calculating visible time windows of all to-be-arranged observation tasks of an imaging satellite; obtaining a core stripe of a to-be-observed region; generating a task pre-planning scheme according to the meteorological data information and core stripe data; loading latest meteorological forecast data in a day before a work plan is sent to the satellite; and determining a final task planning scheme according to the latest meteorological forecast data. An assessment method for judging whether a cloud layer causes shielding to satellite imaging or not has the advantages of simplicity, a relatively small calculation amount and a high calculation speed.

Description

Technical field

[0001] The invention relates to the technical field of imaging satellites, in particular to an imaging satellite mission planning method considering meteorological information. Background technique

[0002] Optical imaging remote sensor is a common sensor mounted on imaging satellites. The vast majority of optical remote sensors are passive remote sensors, which only receive reflections from targets or light radiation emitted by themselves. Among them, the visible light remote sensor is a relatively mature optical remote sensor. It has a large amount of photo information and high resolution, but it can only work in clear daylight and cannot work around the clock. It is easily blocked by clouds, which greatly affects the imaging quality. . According to statistics, about 60% of my country's optical satellite images cannot be effective data products because of cloud cover. This not only fails to meet user needs, but also causes a great waste of satellite resources....
