Beam Forming Tracking terminals like Kymeta are a more recent development in flat panel SOTM terminals. They comprise of all ‘Solid State’ components tending to be much lighter, smaller footprint and cheaper to manufacture. At this stage there are only a few products available and are relatively new to the market.

What is it and how does it work?
ThinKom’s ThinSAT-300 terminal features robust sleek form factor, wide operational temperature range, high tracking speed and wider elevation tracking boundaries. It uses separate TX and RX circular panels with mechanically driven azimuth steering and electronic phased array of platters for elevation tracking.
The patented Continuous Transverse Stub (CTS) array, and the Variable Inclination Continuous Transverse Stub (VICTS) array, benefits from the low-profile, ohmic efficiency, tuneable bandwidth, mechanical robustness, fabrication simplicity, and low-cost advantages inherent (and proven) in the basic CTS design, built upon the 10-year commercial and military history of this innovative antenna technology.
The unique two-dimensional scan mechanism for the VICTS array is 100% mechanical, involving the simple rotation (common and differential) of two coplanar plates, one (upper) comprised of a one-dimensional lattice of continuous radiating stubs and the second (lower) comprised of one or more static line-sources.
As the name implies, mechanical rotation of the upper plate relative to the lower serves to vary the inclination of incident parallel-plate modes and the resultant scan angle in the elevation (theta) plane. Common rotation of the two plates in unison achieves the desired agility in the orthogonal azimuth (phi) direction.
Polarisation control and diversity is supported by adding a fixed or rotating polariser layer(s), mounted conformal to the aperture plate, thereby achieving fixed or selectable circular and/or arbitrarily oriented linear polarisation.
