目前，平流层飞艇在战场态势感知、情报侦察、电子对抗、遥感对地观测、自然灾害预警预报、中继通信等军用和民用领域具有广阔的应用前景。将飞艇艇上遥测信息通过数传系统传回地面，是实现飞艇各项应用的基础。同时，将艇上图像信息实时传回地面，可以监视飞艇运行状态、姿势等，便于地面及时做出调整和控制，确保飞艇长时间平稳的工作。基于这一目的，在FPGA平台上设计了飞艇遥测数传系统,并给出了各模块的详细设计。该系统已应用于飞艇的飞行实验，实验表明该系统可靠稳定，性能良好。
At present, stratospheric airship has broad application prospects in military and civil fields such as battlefield situation awareness, intelligence reconnaissance, electronic countermeasures, remote sensing earth observation, natural disaster early warning and prediction, relay communication, etc. The real-time transmission of telemetry information to the ground station is the basis of implementing these applications. And, the real-time transmission of image information to the ground station can monitor the running state and attitude of the airship, which is easy to control and adjust the airship for the ground station. To achieve this point, this paper designs the data transmission system based on FPGA, and provides the operation principle of each module in detail. The system was used in flight test of the airship and excellent performance was achieved.
