For generic systems, the antenna modelling consists of two elements: pointing and pattern definition. The “Antenna Pointing” panel defines the antenna height, and and the pointing in azimuth and in elevation. The “Antenna Patterns definition” panel as illustrated in Figure 412 is where the pattern across the full range of angles is defined.
The antenna pointing azimuth and elevation angles determine the ultimate antenna gain applied in calculation of the link budget, but not the mutual physical positioning of thetransmitter the transmitter and receiver pair. The latter is determined by the “Path azimuth angle” parameter (see ANNEX 12:).
For generic systems, the antenna modelling consists of two entities in SEAMCAT. You have the “Antenna Pointing” panel that defines the antenna height, the pointing in azimuth and in elevation and you have the “Antenna Patterns definition” panel as illustrated in Figure 410. These antenna pointing azimuth and elevation angles have impact only on the ultimate antenna gain applied in calculation of the link budget, but not on the mutual physical positioning of pair of transmitter and receiver. The latter is impacted by the “Path azimuth angle” parameter (see ANNEX 12:).
