Recently, 502 Institutes of China Aerospace Science and Technology Corporation independently researched and developed China's first all-DOF space-operated full-physics simulation test system and successfully completed the simulation test of the first in-orbit-in-space operation in China using this system. Laying the foundation for the development of China's space vehicle in-orbit service and maintenance.
With the rapid development in the field of aerospace, in recent years, there are over 100 satellites in the world serving God in the world each year. At the same time, the number of orbiting satellites on the orbit has been constantly refreshing the "counter" of space junk. How to achieve on-orbit fault repair of the failed satellites, replacement of relevant modules, and the supplement of satellites and fuels the rejuvenation of space veterans have become the major research directions of various space powers.
Space operation control is a hallmark of space technology entering a new era. Recently, 502 independently developed the first full-DOF space robot ground test system ushered in the "first show."
Locking the target, approaching, capturing, pouring liquid ... Light and coherent action, "dreamlike" "space dance" between the space robot and the target "satellite", so that the experts of the Ministry of Science and Technology Leadership eye-opener. The success of the pilot project has been the "strongest voice" of 502 missions to space operations and intelligent robots.
502 developed rail maintenance and repair autonomous control system has broken through the moving target visual detection and tracking measurement, moving target space three-dimensional motion trajectory identification and prediction, multi-degree-of-freedom robot visual servo and smoothing planning, space manipulator compliance acquisition technology, space Manipulator and platform coordinated control technology to achieve the spatial target tracking close to the position to maintain flexible capture and in-orbit after capture and other functions of ground simulation to verify the in-orbit maintenance maintenance robot system and its related The feasibility of the technology provided an important test reference, and laid a good foundation for the smooth development of the special demonstration of on-orbit maintenance in the five hospitals.
As early as 2013, 502 were looking for space maintenance services in the future, meeting the needs of space intelligent robot development, taking the initiative, self-financing, convening R & D center, SADA center, Imaging Division and Propulsion Systems Division four Departments of the technical elite, set up a joint operation of space operations control team, the initial launch of space operation independent control of key technologies, prototype development and ground-based physical testing and other research work.
Since then, the institute has also built the first space-operated full-scale physics experiment system based on a 6-DOF flotation platform and a 3-DOF flotation platform and has completed a series of experiments including near-distance approximation, safe docking, autonomous arms capture and simulation at The near-end operation of railfloods has taken the first step towards intelligent control of space operations in just a year's success with ground-based physical testing.
At present, major scientific and technological projects for on-orbit service and maintenance have been included in the national agenda. The research results and relevant technical reserves of the project have led the industry in the field of arresting operations, non-cooperation targets near GNC, and space-based debris removal. In front of the task for the follow-up declaration and research has laid a good foundation.
Data Figure: Reconnaissance satellites, remote sensing satellites need to constantly adjust posture or change orbit, fuel has become the bottleneck to limit their working hours, if the "space refueling and maintenance" will make it greatly increased activity time, the average cost of use will be very Low ("oil" here refers to various types of fuel). Space robot-mounted robots can capture space targets and therefore have many other uses.
