GPS Satellite Antenna Panel Patterns
These documents describe the technical characteristics of the antenna panels on the GPS Block IIR and Block IIR-M satellites. The satellite manufacturer, Lockheed Martin, compiled the information based on its design specifications and ground test measurements of the antenna panels. These published antenna patterns and associated Institute of Navigation citation describe both IIR and IIR-M antenna panel versions, their broadcast signal patterns, the performance observed in factory testing, and their on-orbit performance. The posting of this information does not construe, in any manner, an endorsement of any company product or views.
Note: "These patterns represent the current capability of the GPS IIR/IIR-M Space Vehicles. Receiver designers should consult the IS-GPS-200 specifications for use in receiver design and not base design on current signal performance."
