Phase Effects Analysis of Patch Antenna CRPAs for JPALS
The Joint Precision Approach and Landing System (JPALS) is being developed to provide navigation to support aircraft landings for the U.S. military. One variant of this is sea based JPALS, which will be implemented on aircraft carriers. Sea based JPALS will be a dual frequency carrier phase DGPS system. In order to meet strict accuracy, integrity, continuity, and availability goals in the prese...
متن کاملAnalysis of Carrier Phase and Group Delay Biases Introduced by CRPA Hardware
The benefits afforded by Controlled Reception Pattern Antennas (CRPAs) in multipath and interference mitigation are well documented, and they find use in many applications today. As such, CRPAs are being considered for use in the Joint Precision Approach and Landing System (JPALS) program. The Navy variant of JPALS, Sea-based JPALS, will be a dual-frequency, carrier phase, differential GPS syst...
متن کاملNavigation Accuracy and Interference Rejection for an Adaptive GPS Antenna Array
In the Joint Precision Approach and Landing System (JPALS) both the differential GPS reference station and the airborne user will employ Controlled Reception Pattern Array (CRPA) antennas. In a high precision system such as JPALS, CRPA antennas may suffer phase center biases that introduce significant integrity risk. These phase center biases result from both hardware design and from algorithm ...
