The newly launched Fengyun-3D (FY-3D) satellite carried a wide-field auroral imager (WAI) that was developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy Sciences (CIOMP), which will provide large field view (FOV), high spatial resolution, broadband ultraviolet images the aurora ionosphere imaging N2 LBH bands emissions. WAI consists two identical cameras, each with an FOV 68° in along-track direction 10° cross-track direction. cameras are tilted relative to...
The solar X-ray and Extreme Ultraviolet Imager (X-EUVI), developed by the Changchun Institute of Optics, Fine Mechanics Physics, Chinese Academy Sciences (CIOMP), is first space-based ultraviolet (EUV) imager China loaded on Fengyun-3E (FY-3E) satellite supported Meteorological Administration (CMA) for observation. Since started work July 11, 2021, X-EUVI has obtained many images. instrument employs an innovative dual-band design to monitor a much larger temperature range Sun, which covers...
This paper proposes a novel trajectory planning algorithm to design an end-effector motion profile along specified path. An optimization model based on the whale (WOA) is established for time-optimal asymmetrical S-curve velocity scheduling. Trajectories designed by limits may violate kinematic constraints due non-linear relationship between operation and joint space of redundant manipulators. A conversion approach proposed update limits. The path can be divided into segments at minimum...
The Ant Colony Optimization (ACO) is easy to fall into the local optimum and its convergence speed slow in solving Travelling Salesman Problem (TSP). Therefore, a Slime Mold-Ant Fusion Algorithm (SMACFA) proposed this paper. Firstly, an optimized path obtained by Mold (SMA) for TSP; Then, high-quality pipelines are selected from which SMA, two ends of as fixed-point pairs; Finally, pairs directly applied ACO principle fixed selection. Hence, SMACFA with selection obtained. Through test chn31...
In order to solve the problem of poor local optimization Slime Mold Algorithm (SMA) in Travelling Salesman Problem (TSP), a Two-way Parallel by Flow and Distance (TPSMA) is proposed this paper. Firstly, flow between each path point calculated “critical pipeline critical culture” model SMA; then, according two indexes distance, set points be selected obtained; finally, principle with index improved distance added random strategy. Hence, two-way parallel method realized optimal solved...
The inertial sensor is the key measurement payload of technology verification satellite China’s space gravitational wave detection mission-Taiji Project, which uses capacitive sensors to sense acceleration disturbance test mass under influence non-conservative forces in frequency range 10 mHz~1 Hz. It necessary perform a ground performance evaluation and estimate working state orbit. However, due earth’s gravity seismic noise, it impossible directly evaluate resolution level non-sensitive...
Abstract Simultaneous localization and mapping (SLAM) technology is crucial to robot navigation. Despite the good performance of traditional SLAM algorithms in static environments, dynamic objects typically exist realistic operating environments. These can lead misassociated features, which turn considerably impact system’s accuracy robustness. To better address this challenge, we have proposed OMS-SLAM. In OMS-SLAM, adopted YOLOv8 target detection network extract object information from...
This paper first analyzes the external heat flow of a low-orbit space telescope in different flight attitudes, and determines position dissipation surface thermal analysis cases. Then, detailed design each component is completed to reduce influence deformation optical elements supporting structures caused by temperature changes on imaging quality telescope. Especially for control difficulties CCD detectors such as large generation short time one-dimensional movement narrow space, segmented...

Robots rely heavily on environmental maps that are usually built by manually operated simultaneous localization and mapping (SLAM) systems. In scenarios such as disaster rescue enemy probing where operators face accessibility difficulties, mobile robots expected to use active SLAM autonomously explore unknown environments. this work, we establish a three-part framework consisting of environment modeling, goal determination, motion planning for an autonomous robot exploration system. We...
Organic molecules are the main contamination source of space payloads on orbit, and they need to be removed as much possible ground phase. In this paper, based vacuum outgassing rules nonmetal materials methods satellite materials, a simple, high-efficiency, low-cost test method for sensitive instruments was proposed. method, requirements equipment, conditions, terminal criteria, effect evaluation were presented. Using several common tested outgassing. The results show that is efficacious.
