Two Years of ACTS (Advanced Communications Technology Satellite) Propagation Studies in AlaskaThe Alaska Advanced Communications Technology Satellite (ACTS) propagation terminal (APT) is located on top of the engineering building on the University of Alaska Fairbanks campus. The latitude and longitude of the site are 64 degrees 51 minutes, 28 seconds N and 147 degrees, 48 minutes, 59 seconds west. The geometrical elevation angle to ACTS is 7.97 degrees; including a normal atmospheric refractivity, the elevation angle increases to 8.10 degrees. The azimuth angle to ACTS is 129.36 degrees. The terminal is located at 580 feet above mean sea level. The site is located in ITU-R rain zone C and Crane global model zone B1. ACTS transmits vertical polarization beacons at 27.505 and 20.185 GHz. At the APT, the polarization tilt angle is 19.4 degrees rotated CCW with respect to vertical when looking towards the satellite. The beacons are transmitted in a CONUS pattern. The ACTS beacon footprint at the Alaska APT is 9 dB down from the transmission pattern peak at 27.505 GHz and 11 dB down from the pattern peak at 20.185 GHz.
