Automatic Dependent Surveillance-Broadcast (ADS-B) is an air traffic surveillance system in which aircraft broadcast GPS position, velocity and status on 1090 MHz. Nowadays, as a valid alternative to SSR, ADS-B is the main technology for Air Traffic Management (ATM). With the rapid growth of airspace traffic and disappearance of MH370, satellite-based ADS-B is proposed to realize aerial surveillance globally. The satellite-based ADS-B has a series of new features that Terrestrial based does not have including wider coverage, lower SNR. These new features make ADS-B signal collisions at the receiver more severe. This paper is to analyze the collision probability of satellite-based ADS-B messages based on homogeneous Poisson process. According to the theoretical derivation and simulation analysis, a conclusion can be drawn that the collisions of two and three messages dominate in all cases. It helps in guiding the design of the hardware and software of satellite-based ADS-B receiver to focus on the separation of two and/or three collision messages only, which will dramatically reduce the complexity of the system and the load of satellite.

基于齐次泊松过程的星基ADS-B消息碰撞概率研究

自动相关监视广播 (ADS-B) 是一种空中交通监视系统，其中飞机在 1090 MHz 上广播 GPS 位置、速度和状态。如今，作为 SSR 的有效替代品，ADS-B 是空中交通管理 (ATM) 的主要技术。随着空域交通的快速增长和MH370的消失，提出了基于星基的ADS-B在全球范围内实现空中监视。基于卫星的 ADS-B 具有一系列基于地面的新特性，包括更广的覆盖范围、更低的 SNR。这些新功能使接收器处的 ADS-B 信号冲突更加严重。本文基于齐次泊松过程分析星基ADS-B消息的碰撞概率。根据理论推导和仿真分析，可以得出结论，两个和三个消息的冲突在所有情况下都占主导地位。它有助于指导星基ADS-B接收机的硬件和软件设计只专注于分离两个和/或三个碰撞消息，这将大大降低系统的复杂性和卫星的负载。
