Gilat Satellite Networks Introduces SOTM

December 2, 2011, By Sanjeev Ramachandran

A Satcom-On-The-Move (SOTM) solution for airborne applications, which houses a very small Ku-band broadband antenna customized for airborne use, is finally in the lime light.

Gilat Satellite Networks, a leading provider of products and professional services for satellite-based broadband communications networks worldwide, formally announced the introduction of SOTM on Nov 30th.

Moshe (Chico) Tamir, Gilat’s Vice President of Defense and Homeland Security, mentioned that it was Gilat’s strategy of acquiring Wavestream and RaySat Antenna Systems which enabled them to produce a fully integrated solution that benefits from the combined core competencies and technological advancement of the three companies.


He also mentioned that their integrated solution should be the industry’s smallest and most lightweight antenna in its category.

According to Moshe, it is optimal for the defense and military markets as it can address the critical need for reduced weight in order to increase the endurance of unmanned aerial vehicles. This lightweight, compact and low-power terminal, which is ideal for airborne applications, abodes Gilat’s MLT-1000 ruggedized spread spectrum satellite modem, RaySat Antenna Systems’ SR-71, flat panel tracking antenna, and Wavestream’s compact 40W Ku-band block up-converter (BUC) and power amplifier, part of the AeroStream airborne product family.

RaySat Antenna Systems’ SR-71, which supports a high broadband user experience of up to 1 Mbps transmit and 2 Mbps receive, is a very compact and lightweight broadband mobile antenna. It also houses a 6 inch broadband array which tracks any Ku-band satellite position.

The signal to noise ratio of MLT-1000 is very low and this helps it to integrate with the small dimensions of the SR-71 antenna. Also, a 40W BUC that delivers high output-power with low power-draw in a compact and lightweight enclosure adds value to the solution.
