摘要

为了提高航天器的设计水平，满足航天器发展的要求，迫切需要对航天器姿态与轨道控制系统(AOCS)的标定技术进行研究。提出了一种卫星地球传感器模拟器的标定方法，并研制了一种标定装置。基于卫星地球传感器模拟器的工作机理和数学模型，以FPGA和单片机为控制核心，单板计算机通过CAN总线接收和发送动态参数命令，通过求解边沿弦宽信号完成俯仰角和滚转角的标定。该标定装置集成度高，计算效率快，实现了卫星动力学算法和硬件模拟器在整个工作过程中的在线自动标定。有助于姿态轨道控制系统信息域的测量。

Research on Satellite Earth Sensor Simulator Calibration Technology

In order to improve the design level of spacecraft and meet the requirements of spacecraft development, it is urgent to research the calibration technology of spacecraft attitude and orbit control system (AOCS). A calibration method for satellite earth sensor simulator is proposed, and a calibration device is developed. Based on the operating mechanism and mathematical model of the satellite earth sensor simulator, with FPGA and microcontroller as the control core, the single-board computer receives and sends dynamic parameter commands through the CAN bus, completes the setting by solving the edge of the chord width signal Calibration of pitch angle and roll angle. The calibration device has a high degree of integration and fast calculation efficiency, and realizes online automatic calibration of the satellite dynamics algorithm and the hardware simulator during the whole work process. Contribute to the measurement of the information domain of the attitude orbit control system.
