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
