AvL Technolgies 1248K iSNG X/Ku/Ka-Band 1.2M Flyaway VSAT Antenna
The Model 1248K iSNG antenna system is comprised of the following major components:
- AvL Model 1248K iSNG three-axis positioner
- TracStar Controller
The complete system weighs approximately 275 lbs. depending upon the options selected. Further details are provided in the data sheet at the end of this chapter.
The 1.2M iSNG antenna system is an elevation over azimuth positioner featuring the simple, rugged Roto-Lok® drive system that produces very low backlash, high stiffness, and high reliability. It is driven by low backlash gearboxes with DC motors. All drive components are high-strength steel encased in lubricated-for-life housings, resulting in the most reliable, no-maintenance system with minimum weight.
The reflector is an offset, prime focus, 4 or 2-sector carbon fiber reflector illuminated by a corrugated horn. The options for the placement of the transmitter vary depending upon the size: Up to a 4 watt BUC can be installed on the feed boom. An 8-25 watt power amp can be installed on the rear of the reflector, but must be removed for storage. Larger amplifiers must be placed on the ground either in or at the base of the positioner case or in a separate electronics case. Handcrank access is provided on each axis - az, el, and pol - to allow antenna positioning if there is a power failure or a controller malfunction.
The antenna system is packaged in two cases. The positioning system in Case 1, without the case, weighs less than 120 pounds. Case 2 holds antenna struts, feed components, and reflector segments, as well as BUC (if possible), power supply, and hand held controller.
1248K Features Include:
- Reflector Type: 1.2M 2 or 4-piece AvL Carbon Fiber
- Optics: Offset, Prime Focus, 0.8 F/D
- Interchangeable Feeds: Ku LP, Ka CP
- Positioner: Case-based
- Az/El Drive System: Patented AvL Cable Drive Positioner
- Mount Geometry: Elevation over Azimuth
- Polarization Adjustment: Motorized Rotation Feed
- Military Standard: MIL-STD-188-164a Type E-V
The offset reflector/feed system produces co-polarization patterns that easily meet the 29-25 Log θ requirement. The .8 f/d optics reduce off-axis cross-pol in the asymmetrical plane. Depending on the size, the RF power amplifier may be installed in various places as listed above.
Roto-Lok Drive System
The patented Roto-Lok® drive system utilizes highly reliable aircraft control cables in a redundant configuration to achieve a lightweight, very stiff drive system with zero backlash. This high-tech performance is achieved using low-tech components - by simply wrapping the cable around the drive capstan several times before wrapping the larger drive drum. This method results in a minimum free-length of cable. The load cable on the main drum is exponentially reduced as it is wrapped around the drum. Therefore, the total elongation of the cable under load is minimized. The Roto-Lok® system has up to 10 times less backlash than that of comparable gear systems. The cables are pre-tensioned and spring-loaded at the main drum attachment point, which eliminates backlash at installation and any unexpected cable stretch in the future.
The control system is produced by TracStar Systems per direction of AvL. The controller includes a tunable receiver, GPS system, and flux-gate compass. The main portion of the controller is located on the antenna positioner to place it close to the optical encoders. The power supply and hand-held controller are separate and can be placed up to 25 feet away without special hardware. Special control cables can be obtained to place the power supply and hand-held up to 200 feet away.
The TracStar controller was developed to achieve one-button, auto-acquisition of the satellite signal 100% of the time using a proprietary method. The controller peaks the antenna on the data satellite with greater accuracy than a human can achieve, thus assuring that there is no chance of adjacent satellite interference. Primary and secondary reference satellite menus and data satellite menus are available for an untrained operator. Any data satellite can be selected or pre-programmed by a trained operator. Semi-automatic modes are available in case of failure of GPS or flux-gate to provide acceptable manual input of case heading and/or latitude and longitude.
