Conceptual Study on Civil UAS Operation under Advanced CNS/ATM Systems

Project Information

• This work has done under the consignment research project supported by Korea Advanced Institute of Science & Technology (KAIST) and it is a part of the project “Flight Safety Regulation Development and Integrated Operation Demonstration for Civil RPAS” funded by Ministry of Land, Infrastructure, and Transport of South Korea.  

• Period: June 29, 2016 – April 28, 2017  

• Participants: Jooyoung Lee, Dawei Sun

Objective

The objective of the proposed research is to perform a study on future Communication, Navigation and Surveillance (CNS)/Air Traffic Management (ATM) systems for civil Unmanned Aircraft System (UAS).

Task 1: Review of global trend of state-of-the-art CNS/ATM systems for civil UAS

Task 2: Development of UAS Tracking Algorithm for UTM with Geofencing 

UAS Tracking Problem

• Actual trajectory of UAS can deviate from a predefined geofence

• Cause degradation in safety and efficiency of UTM system 

=> UAS trajectories should be accurately tracked and monitored

Challenges in UAS Tracking

• Complex motion of UAS composed of a sequence of flight motions

• UAS trajectory is restricted to be within an assigned geofence

Research Goal 

To develop a UAS tracking algorithm to account for the challenges 

• More accurate tracking performance than the existing tracking algorithm

• Support the safe and efficient operation of UTM system
