Advanced Global Positioning System Hybrid Simulator

The objective of this SBIR is to produce a GPS simulator, which incorporates the new civil and military signals and provides for controlled reception pattern antenna testing. In Phase I a system design was developed for the Advanced GPS Hybrid Simulator(AGHS) which incorporated the capability to test new GPS technologies including (but not limited to) the new civilian and military signal structures, Controlled Reception Pattern Antennas (CRPA), the Wide Area Augmentation System (WAAS), the Local AreaAugmentation System (LAAS), and the Joint Precision Approach Landing System (JPALS), all in compliance with the new SAASM security requirements.The AGHS simulator is a hybrid software, digital and radio frequency (RF) GPS simulator design. Our design heavily leverages existing software and digital signal simulation components previously developed by NAVSYS which were used to prototype an AGHSsystem under the Phase I effort. In addition to providing digital and RF signal simulation capability, the AGHS can also be used to record and play-back real-world GPS signals from field tests.Under Phase II, an AGHS will be built and delivered for test and evaluation by the 746th Test Squadron
