Service Type

Click the Service drop-down list to select a service type. Service determines the frequency bands available and type of earth station (fixed or mobile). It also determines whether the earth station acts as a transmitter, a receiver or both at the same time.

A frequency is automatically chosen from the range of allocated bands for the given service. These bands are taken from the Radio Regulations. The lowest frequency band is chosen as the default, as this will give the largest coordination contour. You can and should change this band to reflect the properties of the earth station you are coordinating.
