Abstract

The primary technique used for air traffic surveillance is radar. However, nowadays, its role in surveillance is gradually being replaced by the recently adopted Automatic Dependent Surveillance-Broadcast (ADS-B). ADS-B offers a higher accuracy, lower power consumption, and longer range than radar, thus providing more safety to aircraft. The coverage of terrestrial radar and ADS-B is confined to continental parts of the globe, leaving oceans and poles uncovered by real-time surveillance measures. This study presents an optimized Low-Earth Orbit (LEO)-based ADS-B constellation for global air traffic surveillance over intercontinental trans-oceanic flight routes. The optimization algorithm is based on performance evaluation parameters, i.e., coverage time, satellite availability, and orbit stability (precession and perigee rotation), and communication analysis. The results indicate that the constellation provides ample coverage in the simulated global oceanic regions. The constellation is a feasible and cost-effective solution for global air supervision, which can supplement terrestrial ADS-B and radar systems.

利用优化的 ADS-B 立方体卫星星座进行空中交通监测

用于空中交通监控的主要技术是雷达。但如今，雷达在监控中的作用正逐渐被最近采用的自动监视广播（ADS-B）所取代。与雷达相比，ADS-B 具有更高的精度、更低的功耗和更远的距离，从而为飞机提供更多的安全保障。地面雷达和 ADS-B 的覆盖范围仅限于全球大陆部分，海洋和极地没有实时监控措施。本研究提出了一种优化的基于低地轨道（LEO）的 ADS-B 星群，用于洲际跨洋航线上的全球空中交通管制。优化算法基于性能评估参数，即覆盖时间、卫星可用性和轨道稳定性（前摄和近地点旋转）以及通信分析。结果表明，该星座在模拟的全球海洋区域提供了充分的覆盖。该星座是一个可行且具有成本效益的全球空中监管解决方案，可作为地面 ADS-B 和雷达系统的补充。
