Sec. 25.277  Temporary fixed earth station operations.

    (a) When an earth station in the Fixed-Satellite Service is to 
remain at a single location for fewer than 6 months, the location may be 
considered to be temporary fixed. Services provided at a single location 
which are initially known to be of longer than six months' duration 
shall not be provided under a temporary fixed authorization.
    (b) When a station, authorized as a temporary fixed earth station, 
is to remain at a single location for more than six months, application 
for a regular station authorization at that location shall be filed at 
least 30 days prior to the expiration of the six-month period.
    (c) The licensee of an earth station which is authorized to conduct 
temporary fixed operations in bands shared co-equally with terrestrial 
fixed stations shall provide the following information to the Director 
of the Columbia Operations Center at 9200 Farmhouse Lane, Columbia, 
Maryland 21046, and to the licensees of all terrestrial facilities lying 
within the coordination contour of the proposed temporary fixed earth 
station site before beginning transmissions:
    (1) The name of the person operating the station and the telephone 
number at which the operator can be reached directly;
    (2) The exact frequency or frequencies used and the type of 
emissions and power levels to be transmitted; and
    (3) The commencement and anticipated termination dates of operation 
from each location.
    (d) Transmissions may not be commenced until all affected 
terrestrial licensees have been notified and the earth station operator 
has confirmed that unacceptable interference will not be caused to such 
terrestrial stations.
    (e) Operations of temporary fixed earth stations shall cease 
immediately upon notice of harmful interference from the Commission or 
the affected licensee.
