Abstract
The necessity of a positioning service for various ground handling assets is key to improving airport performance. Reported in this article is a system named “Ground Eye”, designed to be a test of a possible implementation of the independent LTE-based communication system and GNSS-based location services. The test campaign used a total of nine prototype devices for a period of one month at Gdańsk airport (Poland). The main goal of this demonstration was to verify the possibility of using the GNSS/LTE system as a fast-deployment option in the airport environment, as well as to evaluate its positioning and communication capabilities in conjunction with React.JS/Deck.GL/Node.JS dedicated application. The test campaign verified that even with simple processing and relatively simple single-frequency measurements, multi-constellation GNSS receivers, it is possible to obtain location with precision reaching better than 2.5 metres. This precision should be good enough for all ground handling operations at modern airports, without the need for additional fixed infrastructure.
Highlights
Typical ground handling operations within any commercial airport that are capable of servicing passenger airplanes requires a multitude of ground support assets
Multilateration is not as flexible as direct GNSS measurements and it was not intended to cooperate with a large number of assets, which is the case of almost every airport
The purpose of this study was to design, build and test whether or not it is possible to operate a ground handling asset tracking system capable of providing a location with at least 50% of positions being within 2.5m distance from their physical locations and if such system can be operated reliably
Summary
Typical ground handling operations within any commercial airport that are capable of servicing passenger airplanes requires a multitude of ground support assets. The larger the airport is, the more ground equipment it is required to accommodate for concurrent aircraft servicing. Even in a medium-sized airport, the number of assets can be counted in hundreds of items. The typical ground handling operations for the most part still rely on radio voice communications, even though airports are one of the areas where digital tracking systems were available early. As of 2021, these systems depend on multilateration positioning rather than direct GNSS service. Multilateration is not as flexible as direct GNSS measurements and it was not intended to cooperate with a large number of assets, which is the case of almost every airport
