商业航天测控设备数传基带日志数据

高速数传基带主要完成对高分低轨卫星、临近空间飞艇和航空无人机下传的数据进行解调、帧同步、解扰和译码等任务。基带工作过程中接收板的DSP、FPGA及上位机工作正常与否直接影响解调后的数传数据质量，当数据误码率达到一定阈值时当圈数据就无法使用。数传基带日志实时记录基带载波锁定、位同步、帧同步状态，同时记录接收机AGC电压、译码坏帧数量、下行载波多普勒频率，这些日志信息对于分析天线跟踪情况、设备工作状态十分必要。The high-speed data transmission baseband mainly undertakes tasks such as demodulation, frame synchronization, descrambling and decoding for the data downlinked by high-resolution low Earth orbit (LEO) satellites, near-space airships and aerial UAVs. During the operation of the baseband, whether the DSP, FPGA and host computer of the receiving board operate properly directly affects the quality of the demodulated downlink data. When the bit error rate (BER) reaches a certain threshold, the per-pass data will become unavailable. The data transmission baseband logs record the baseband carrier lock, bit synchronization and frame synchronization status in real time, as well as the receiver's AGC voltage, number of corrupted decoded frames and downlink carrier Doppler frequency. These log data are extremely necessary for analyzing antenna tracking status and equipment operating conditions.
