NATIONAL AERONAUTICS AND SPACE ADMINISTRATION TRACKING AND
DATA RELAY SATELLITE SYSTEM EARTH STATION IN BLOSSOM POINT,
Report No. SPB-258
The International Bureau announces that effective September 8, 2014, the National Aeronautics
and Space Administration (NASA) Tracking and Data Relay Satellite System (TDRSS) earth
station operating in the 14.0-14.2 GHz band at Blossom Point, MD (coordinates 38°25’44’’
North and 77°05’02’’ West) will become fully operational. The terrain height of the Blossom
Point earth station site is approximately mean sea level.
Sections 25.222(c), 25.226(c), and 25.227(c) of the Commission's rules require all Earth Stations
on Vessels (ESV), Vehicle-Mounted Earth Stations (VMES), and Earth Stations Aboard Aircraft
(ESAA) to cease operations in the 14.0-14.2 GHz band within 125 km (in the case of ESV and
VMES) or radio line-of-sight (in the case of ESAA) of the new TDRSS site until after the
operator completes coordination for the new TDRSS site. 1
