1. Introduction This report examines whether or not there exists a radio line-of-sight (RLOS) between existing GPS antennas and the proposed wind turbines in Eight Point Wind Energy Center, New York. The GPS antennas are registered with the NOAA CORS database and are used for surveying purposes.
2. Project Overview

Based on the information provided, Comsearch generated a cross-sectional elevation profile in order to determine if there would be any terrain blockage between the antennas in question and the proposed wind turbines. The profiles can be seen in Figures 3 - 5 which shows a terrain obstructed path between the closest three GPS antennas and the closest wind turbine to each.

4. Impact Assessment
Using a digital terrain model, Comsearch generated a path profile between the closest three CORS registered GPS towers and the proposed wind turbines and determined that there currently exists terrain blockage. These antennas generally service equipment in a range of ten miles. Since the Eight Point Wind Energy Facility is more than ten miles from these sites, and all profiles showed terrain blockage, it can be determined that the proposed turbines are sited outside the service range of these antennas and will not cause interference to their operations.
