A Miniaturized GPS Antenna Array Technology That Reduces The Size Of The Antenna Elements And The Array Dimensions. This Technology Enables GPS Controlled Reception Pattern Antenna Arrays (Crpas) With Anti-Jamming Capability To Be Installed On Vehicles Where Their Size Has Previously Prohibited Their Use. This Includes Aircraft Where Size And Weight Constraints Resulted In Fixed Reception Pattern Antenna (FRPA) Installations Instead Of Crpas And Munitions Where Space And Surface Area Are At A Premium.OEING Has Developed AGHA ST™ (Another GPS High Anti-Jam Simulation Tool), Which Allows The Anti-Jam Performance Of Crpas And Their Null-Steering Electronics To Be Predicted. Using Detailed Antenna Pattern And Coupling Data Collected In The Instrumented Anechoic Chamber At Boeing, AGHAST™ Can Accurately Predict The Expected Installed Performance Of Anti-Jam Hardware In A Jamming Environment.
