ATSEP Use Cases: Impact of Target Tracking Errors on ATC

Written by Darakhshan Zaidi | Jun 06, 2024

Target tracking errors in ATC processing compromise situational awareness, increase collision risks, and hinder operational efficiency, impacting safety and airspace management.

Definition of Target Tracking Errors  in context of Processing Errors 

Target tracking errors in the context of processing errors refer to inaccuracies or discrepancies in tracking and maintaining the position, speed, trajectory, or identity of aircraft or other targets within the air traffic control system. These errors can arise from data inconsistencies, sensor limitations, or computational mistakes, leading to compromised tracking accuracy and potential safety risks.

What is Target Tracking Errors  in context of  Processing Errors with an example

Target tracking errors in the context of processing errors refer to deviations or discrepancies in accurately tracking and maintaining the position, speed, trajectory, or identity of targets within the air traffic control system.

For example, consider a radar system that is responsible for tracking aircraft. If the radar system experiences a processing error, it may incorrectly estimate the position or speed of an aircraft, leading to a target tracking error. This can result in the system displaying an aircraft at an incorrect location on the radar screen or providing inaccurate information to air traffic controllers. Such errors can introduce confusion and potential safety risks if the controllers make decisions based on erroneous tracking data.

Give a scenario in pedagogical way that illustrates the impact of Target Tracking Errors  related to Processing Issues on Air traffic Control Services

Scenario 1 Conflict Resolution Error

Imagine an air traffic control scenario where two aircraft are on converging paths. Due to target tracking errors caused by processing errors, the system incorrectly estimates the position and speed of one of the aircraft. As a result, the system fails to detect the potential conflict and does not provide timely instructions to the pilots. This leads to a critical situation where the two aircraft come dangerously close to each other, increasing the risk of a mid-air collision.

Scenario 2 Misidentification and Communication Error

In another scenario, air traffic controllers receive tracking data from multiple sources, including radar and surveillance systems. However, due to target tracking errors caused by processing errors, the system misidentifies an aircraft, associating it with the wrong flight number or identification code. This leads to confusion in communication with the pilot and other involved parties. As a consequence, incorrect instructions or clearances may be given to the aircraft, potentially leading to miscommunication, compromised situational awareness, and operational disruptions.

These scenarios illustrate how target tracking errors resulting from processing errors can have significant implications on air traffic control services, compromising safety, introducing conflicts, and impacting effective communication and decision-making processes. It highlights the critical importance of accurate target tracking in maintaining the integrity and efficiency of air traffic control operations.

These errors can be caused by inaccurate initial state estimation, imperfect modeling of target behavior, or processing errors in prediction algorithms.

Identification Errors

Identification errors occur when there are mistakes in associating the correct identification code or flight number with a target.

These errors can lead to miscommunication, confusion, and compromised situational awareness.

Track Switching Errors

Track switching errors occur when the system incorrectly switches or merges tracks of different targets.

This can result in incorrect associations between targets and lead to tracking errors and confusion in target identification.

Track Loss Errors:

Track loss errors happen when the system loses track of a target temporarily or permanently.

This can occur due to data transmission errors, sensor limitations, or computational mistakes in tracking algorithms.

Data Fusion Errors

Data fusion errors occur when integrating and combining data from multiple sources leads to inconsistencies or incorrect information in the final tracking output.

These errors can arise from challenges in data synchronization, coordination, or fusion algorithms.

Understanding these common types of target tracking errors in the context of processing errors is essential for developing effective error detection, mitigation, and correction mechanisms within air traffic control systems.
