Automatic dependent surveillance-broadcast (ADS-B) has been widely used due to its low cost and high precision. The deep learning methods for ADS-B signal classification have achieved a performance. However, recent studies shown that networks are very sensitive vulnerable small noise. An poisoning method based on Generative Adversarial Network is proposed. This can generate poisoned signals. On...

Unmanned aerial system (UAS) traffic management (UTM) requires each UAS to communicate with other and stakeholders involved in the operation. In practice, there are two types of wireless communication systems established community: automatic dependent surveillance broadcast (ADS-B) remote identification (Remote ID). between these systems, is ADS-B-like which leverages using communications avail...

With the advancement of Communication, Navigation and Surveillance (CNS) technologies such as space-based Automatic Dependent Surveillance-Broadcast/Contract (ADS-B/C), large separation minima may be reduced in procedural airspaces. It is great significance to know upper limit Reduced Separation Minima (RSM) for a airspace corresponding consequences on collision risk with specifics advanced ADS...

Automatic Dependent Surveillance-Broadcast (ADS-B) is the direction of airspace surveillance development. Research analyzing the benefits of Traffic Collision Avoidance System (TCAS) and ADS-B data fusion is almost absent. The paper proposes an ADS-B minimum system from ADS-B In and ADS-B Out. In ADS-B In, a fusion model with a variable sampling Variational Bayesian-Interacting Multiple Model (...

The Internet of Things (IoT) provides applications and services that would otherwise not be possible. However, the open nature IoT makes it vulnerable to cybersecurity threats. Especially, identity spoofing attacks, where an adversary passively listens existing radio communications then mimic legitimate devices conduct malicious activities. Existing solutions employ cryptographic signatures ver...

Altimetry System Error (ASE) is a measure of the height-keeping performance of an aircraft. In airspace where the Reduced Vertical Separation Minimum (RVSM) is applied, the importance of accurate aircraft height-keeping is magnified. ASE is not detectible in routine operations; specialized measurement equipment is necessary to independently measure the errors. To be eligible for RVSM operations...

This paper presents a time-based path planning optimizer for separation assurance for unmanned aerial systems (UAS). Given Automatic Dependent Surveillance-Broadcast (ADS-B) as a sensor, position, velocity, and identification information is available at ranges on the order of 50 nautical miles. Such long-range intruder detection facilitates path planning for separation assurance, but also poses...

Health and usage monitoring systems (HUMS) are the basis for condition-based maintenance of helicopters. One most critical in terms safety expense that can be monitored by HUMS main gearboxes helicopters with turbine engines. While health part aims to model state from collected sensor data advanced algorithms, such as machine learning, tracks time use operating parameters system, load, determin...
