 DAFUSA TR 1018
Data Fusion for Airports
Setting the Scene
The purpose of the DAFUSA study was to define, implement and validate new multi-sensor data fusion algorithms, in order to improve the Surveillance and (part of) the Control function of future Surface Movement Guidance Control Systems (SMGCS).
Approach
The different steps of the project were:
-description of operational needs and technical survey
-specification of functional requirements
-modelisation of sensors
-specification of data fusion algorithms
-development of the DAFUSA simulator
-functional validation
-operational evaluation and validation
-cost effectiveness and deployment plan.
Results and Achievements
Three kind of results are expected from the DAFUSA simulator:
Data fusion algorithms
DAFUSA will provide, test and validate data fusion algorithms, according to the specific needs of airport ground traffic. The validation will be based on criteria already identified, such as accuracy, availability and integrity of the fusion results, probability of false conflict detection, target identification delay.
The algorithms will be adapted to the families of sensors and communication techniques which are studied in the project but should be reusable to integrate other technologies.
Analysis tool
The high generic level of the DAFUSA prototype will make the simulation of new specific environments (airport layout, mobiles, circulation rules ...) easier. DAFUSA will help the airport authorities for the choice and positioning of sensors in future SMGCS.
Component of a complete SMGCS
DAFUSA must be easily connected to related European Projects of the Telematics Application Programme. It will provide a simulation and an assessment of the ground dynamic traffic to projects such as MANTEA, ATHOS and AIRPORT-G.
Conclusions and plans for the future
The project DAFUSA has provided the following tools to the airport engineering department:
-a surveillance multi-sensor data simulator connected to a scenario generator
-data fusion algorithms implemented in the simulator
-simulation results interpreter with statistical functions
The exploitation plan of DAFUSA can be summarised as follows:
-to propose performant data fusion algorithms to Airport Authorities
-to experiment new data fusion algorithms
-to simulate new types of sensors
-to help Airport Authorities in the choice, positionning and parameterisation of sensors related to ground detection
-to integrate the Surveillance function developed in DAFUSA, in a complete SMGCS.
