Abstract

The present invention provides an embedded observation control system of a precision-measurement space target telescope, and relates to the technical field of precious measurement of space target telescopes. The defects are solved that a current observation control system is achieved through a main control computer and is low in artificial recognition space target efficiency and long in recognition time and the problem that remote control cannot be achieved through LAN, WAN or Internet. The system provided by the invention comprises a motion controller, a data collector, a data processor and observation control software. The telescope motion controller is used for height axis drive, azimuth axis drive and collection of coded disc data; the data collector is used for collection of CCD imagedata, CCD exposure time control and latching of the CCD exposure time; the data processer is used for pre-processing of the CCD image, identification of space target images and celestial fix of the space target; and the observation control software generates an observation plan of the space target, manages the telescope motion controller and the CCD data collector to complete telescope observation flow and guide the data processor to process the observation data.

Description

technical field [0001] The invention relates to the technical field of precision measurement of a space object photoelectric telescope, in particular to an embedded observation control system of a precision measurement type space object photoelectric telescope. Background technique [0002] The ground-based space target photoelectric telescope is the main equipment for observing space targets, especially space debris. [0003] The working process of the precision measurement photoelectric telescope to observe the space target is roughly as follows: the telescope waits according to the forecast position, after finding the target, guides the telescope drive system to track the target according to the guidance data of the target, and collects CCD images, code disk data and clock Signal, when processing the CCD image, in addition to the position of the target, the position of the calibration star (background star) should also be given. Through the relative position of the target...
