GPS Global Antenna Pattern

Models a satellite GPS antenna. This antenna models a GPS satellite antenna operating a Global Beam on the L1 or L2 frequency channel for Block type II-A satellites.

This antenna uses a polar coordinate system.

Field	Description
Design Frequency	The frequency of the antenna. For an embedded antenna on a receiver, transmitter or radar, this value corresponds to the Frequency entered on the Model Specs tab for the transmitter or receiver and the Transmitter Specs tab for the Radar. For an antenna linked to a receiver, transmitter, or radar, the Antenna Design Frequency value gets overridden by the Frequency value set on the Model Specs tab for the transmitter or receiver, and the on the Transmitter Specs tab for the Radar. However, when computing the antenna's gain matrix (or a link budget, etc.) from one of the objects linking to the antenna, that other object's frequency settings override the antenna's Design Frequency setting.
Block Type	Each satellite belongs to a particular family, called a satellite block type. Different satellite blocks have different properties.
Efficiency	The efficiency factor of the antenna, varying from 0 to 100 percent. Since no antenna is perfect, the efficiency factor allows you to specify the degradation in performance.
Maximum Gain	Read-only value. The gain of the GPS Global antenna.
Beamwidth	Read-only value. Fixed at 30 degrees.
