TRANSDERMAL PROSTAGLANDIN E1 TO TREAT MALE IMPOTENCE

Not Available The Phase 1 project examines the concept of low-cost and low RCS GPS protection capability for advanced rotary wing aircraft using an L1/L2 antenna retrofit. The project examines the tail stabilizer GPS antenna installation of the Comanche RAH-66 and forward antenna location for factors including: installation detail, signature, GPS coverage, blockage/masking, and onboard interference. The project employs ERI's patented single aperture, COTS A/J technology. The project examines alternate antennas (i.e., cross-slot cavity backed in turnstile and square box arrangements and patches) to optimize GPS and A/J performance. The project examines active antenna arrangements with electronics at the antenna and in the E-bay near the receiver. The objective is to provide a retrofit solution that has low acquisition and installation cost. The Phase 1 Option addresses partitioning and package trades for electronics between E-bay and aperture locations. Phase 2 develops and tests a prototype L1/L2 antenna for the RAH-66 consisting of an active antenna with modified COTS electronics for demonstration. Phase 2 builds, modifies and integrates the anti-jam system on an airframe with the existing GPS receiver, and supports test planning and demonstration that scopes anti-jam performance and signature impact. BENEFITS: The program develops a low-RCS, robust active antenna and electronics concept for GPS protection. Phase 1 conducts essential research, determines the scope of performance
