NAVIGATOR 45-III STEERABLE SATELLITE ANTENNA
Since 1984 SSE has produced a cost effective, three axis steerable interface for the popular Series 8345 4.5-meter satellite antenna. These systems have been designed for affordability,
reliability and easy installation and maintenance. The Navigator 45-III provides complete domestic arc satellite
access from any point in the U.S. with pointing accuracy and mechanical stability even where high-wind structural
loading conditions are encountered. The Navigator 45-III can be installed as a turnkey new unit and is also available
as bolt-on retrofit for existing Series 8345 Antennas.
The Series 8345 antenna system has long been the industry standard where 4.5-meter antennas are concerned.
The reflector consists of twelve stretched steel panels attached to radial beam supports to provide a very accurate
parabola. The surface tolerances inherent in the Series 8345 support both C and Ku-band in receive and TRANSMIT/UPLINK
operations. Appropriate range-test information is available on request. The unique tripod mount provides a highly
stable platform that supports our steerable interface.
STEERABLE INTERFACE MECHANICS
The Navigator 45-III Steerable Mount Interface provides all the equipment to upgrade a manual - existing or new -
Series 8345 to motorized capability in azimuth, elevation and feed system for true, three-axis capability. The primary
components consist of motorized elevation and azimuth machine screw actuators, a precision azimuth turntable bearing,
a structural load frame for antenna mounting, structural attachment plates to evenly distribute the loads from the
antenna to the mount legs and foundation and high strength hardware for assembly. Other features are:
- High strength and stiffness provide pointing accuracy even in high wind conditions.
- Designed for new antenna installation or bolt-on retrofit to existing antennas with no field drilling,
cutting or welding required.
- Simple and easy installation with just two technicians.
- Precision five-ton capacity (Joyce-Dayton) jackscrews ensure smooth and controlled azimuth and
- 360° adjustability for initial azimuth travel; no pre-orienting necessary.
- Galvanized and powder-coated finishes for corrosion protection.
- Heavy-duty, 36 volt DC Motors and upgraded Controller for sustained output voltage to drive units.
- No AC Power required at antenna site.
A popular feed system upgrade is our motorized SSE-MFS-1CKu. The feedhorn has four-port feed capability for simultaneous dual
polarization operations in both C and Ku-bands. The Controller is upgraded to support the Feed System and can be programmed
to provide instant backup of a failed LNB. The feed system provides for both C and Ku-band satellite access with the
Controller selecting the desired - Vertical or Horizontal - polarization
SSE uses the Research Concepts Model RC2000A to provide for antenna positioning tasks. The RC2000A will program the positions of
up to fifty satellites. There is also a version available that will provide tracking capability for inclined-orbit satellites in
addition to the (fifty) geo-stationary satellites.
An Autopilot software package is available that can handle scheduling and receiver tuning tasks. It also features communications
capability for off-site access.
