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
