Embodiment Construction

[0017] 1. Function and Composition

[0018] The extravehicular mobile monitor of the space station has strict restrictions on weight, volume, power consumption, etc. The invention is used for the navigation, control and imaging system of the mobile monitor outside the space station, adopts the integrated design idea, and is equipped with micro-miniature components, so that the space station can be independently relatively navigated, controlled and imaged and monitored.

[0019] Such as figure 1 As shown, the system of the present invention is mainly composed of a relative navigation measurement subsystem, an attitude and trajectory control subsystem, and a monitoring imaging subsystem.

[0020] The main functions of the relative navigation measurement subsystem are: to complete the relative navigation measurement based on the space station, to perform high-precision imaging of a specific area, and to provide a collision warning between the monitor and the space station. The ...

Abstract

The invention relates to a navigation, control and imaging system for a flexible monitor out of a cabin of a space station. The system mainly consists of a relative navigation measuring sub system, a gesture and track control sub system and a monitoring and imaging sub system. The relative navigation measuring sub system comprises a forward camera, a lateral camera, a marker array, and a GPS (Global Positioning System) receiver. The gesture and track control sub system comprises a gyroscope, a thrustor assembly and a control computer. The monitoring and imaging sub system comprises a digital camera, a CMOS (Complementary Metal-Oxide-Semiconductor Transistor) camera, and the forward camera and the lateral camera in the relative navigation measuring sub system. Besides the control computer, the above assemblies are micro-components. According to the system provided by the invention, the flexible monitor out of the cabin of the space station can monitor extravehicular activities of astronauts, probe the abutting terminal of the space station, monitor the rendezvous and docking process of the space station and shoot and detect from a near distance to typical positions in a condition of meeting constraints of volume, weight, energy consumption and the like.

Description

technical field [0001] The invention relates to a system or device which can be installed on an external mobile monitor independent of the space station and can carry out autonomous relative navigation, control and imaging monitoring of the space station. Background technique [0002] Since the 1980s, with the research and development of manned spaceflight and space stations, in order to conduct on-orbit extravehicular state inspections of manned spacecraft and space stations (such as optical surface inspection, measurement of surface temperature, discovery of structural damage, mechanical failure, etc.) , and monitor the extravehicular activities of astronauts. The international community has carried out in-depth research and development on spacecraft with extravehicular maneuver monitoring functions, and developed corresponding spacecraft and launched them into the sky. Typical ones are: AERCam (Autonomous EVA Robotics Camera) Sprint of the United States, Inspector coopera...
