Title: Self-Orienting Low-Drag UHF Nanosatellite Antenna
Agency / Branch: DOD / NAVY
Contract: N66001-11-C-5218
Award Amount: $1,137,482.00


Physical Optics Corporation (POC) proposes, in Phase II, to mature the first-of-its-kind Self-Orienting Low-Drag UHF Nanosatellite Antenna (SOLUNA), developed and proven feasible in Phase I. The SOLUNA design provides over 9 dBi right-hand circularly polarized (RHCP) gain in the Mobile User Objective System 300-320 MHz and 360-380 MHz bands, meets CubeSat Design Specifications, including mass and volume, and has low atmospheric drag, ensuring at least 2 years of operational life in a low-earth-orbit environment. An associated full-duplex transceiver for up to 1 watt transmit power and -100 dBm receive sensitivity was designed by POC, as well as a passive attitude control mechanism that aligns and stabilizes the satellite in roll, pitch, and yaw, and ensures that the satellite is oriented in the direction of minimum drag with the antenna directed toward the Earth. In Phase II, a prototype antenna and duplexer will be developed based on the Phase I design. The performance of the prototype will be evaluated at a UHF antenna range and in a thermal vacuum representative of the envisioned low-earth-orbit. Based on the outcome of these tests, the SOLUNA design will be refined and its concept of operations updated.
