The parameters below specify a "safety cylinder" with radius H and height V. Each aircraft has its own cylinder, based on its type. A Kalman filter is used to detect potential convergence, i.e., the possibility that among each pair of aircraft at least one will enter another’s safety cylinder in T seconds. This is considered a pontential collision and a warning will be issued.

• The following values have been adapted for use with UgCS ADS-B collision warning service, among two classes of aircraft:

Values for vehicles controlled by UgCS (assumed to be drones):

Parameter	Parameter	Unit of measurement
H (horizontal distance)	20	Metres
V (vertical distance)	15	Metres
T (warning time )	60	Seconds

Values for vehicles observed by UgCS (assumed to be planes, values based on ICAO recommendations): Parameter Value Unit of measurement

Parameter	Value	Unit of measurement
H (horizontal distance)	9260 (5)	Metres (Nautical Miles)
V (vertical distance)	300	Metres
T (warning time )	60	Seconds
