Antenna control method for ensuring reliable data transmission of lunar surface unmanned automatic sampling task

Abstract

The invention provides an antenna control method for ensuring reliable data transmission of a lunar surface unmanned automatic sampling task, which can ensure'coarse pointing 'of rapid pointing timeliness and 'fine adjustment' of high bit rate accurate pointing in the sampling process, and meets the control requirements of compact timing sequence of lunar surface sampling work and high precision of an antenna. According to the invention, a target pointing control method of 'rough pointing'+ 'fine adjustment' is implemented, so that antenna pointing can be completed in the shortest time and the optimal path within the limited time in the unmanned automatic sampling process of the lunar surface, the implementation of the lunar surface sampling task is reliably ensured, the method has very important significance for engineering implementation of tasks with compact time sequence and high data transmission requirements, such as lunar surface / extraterrestrial celestial body surface unmanned automatic sampling.

Description

technical field [0001] The invention relates to the technical field of antenna pointing target control, in particular to an antenna control method for ensuring reliable data transmission for unmanned automatic sampling tasks on the lunar surface. Background technique [0002] The unmanned lunar surface sampling task includes two major tasks: drilling sampling and packaging and surface sampling and packaging. Before each sampling operation, confirmation of the topography and landform of the sampling target area and the lunar soil environment is the basis for sampling. ;During the implementation of sampling work, it is necessary to monitor the sampling status throughout the whole process to ensure that there are visible images in the whole process of sampling point selection, target point sampling, sample transfer, and sample stakeout; The status of the sample and the packaging status of the sample are confirmed. At the same time, it is necessary to ensure that the sampling me...

Problems solved by technology

Since the antenna pointing is realized by the autonomous control of the spacecraft, this method is greatly affected by the above-mentioned ephemeris accuracy and the calculation accuracy of the spacecraft control center. It is easy to cause data transmission interruption due to the incorrect pointing of the antenna and the failure to point to the target in time, which seriously affects the moon.
