XTAR continues to demonstrate high data rates for small terminals

(9 October 2018 - XTAR) XTAR has announced the results of a July demonstration at Fort A.P. Hill, Virginia.

Partnering with Honeywell, Leidos and Newtec, XTAR’s demonstration was designed to provide a SATCOM on the move (SOTM) data link from a SOTM terminal to a hub earth station at a data rate greater than 25 Mbps. The goal was to show that high data rates can be achieved from small SOTM terminals without the use of High Throughput Satellites.

For the demonstration, XTAR used Honeywell’s Wavestorm AS-X, which is a low profile slot array antenna, suitable for either airborne or ground-based applications. The satellite used for this demonstration was the XTAR-LANT satellite located at 30°W longitude. XTAR-LANT is an Xband satellite, compatible with WGS terminals, with both global and spot beams.

A 26 Mbps satellite link was achieved between the terminal and a fixed 3.9m ground station. A 2 Mbps data link was transmitted from the fixed ground terminal to the SOTM terminal. The required space segment for the demonstration was an impressive 38.2 MHz with bandwidth efficiency of 0.73 bits/Hz, which is considered exceptionally high performance for a terminal of this size. As heavy rain began to fall, the satellite link held strong.

“These results are yet another confirmation of the power of X-band,” states Jay Icard, President and Chief Executive Officer at XTAR. “The frequency is efficient with small terminals, works well in mobile situations and remains strong in rain, wind or dust storms.”

Results from this demonstration were similar to those conducted at Bridgewater, Virginia in October, 2017 and strengthen the company’s offering to its users. As Kelly Nicklin, Vice President Sales and Marketing explains, “Less bandwidth translates into lower costs which is important for our customer. XTAR only serves the government user who requires cost efficiency combined with resilient performance.”
