Ka-band certification enables wider use of RHN 9.2-Meter antennas

SATCOM Technologies' 9.2-Meter satellite communications antennas used at Regional Hub Nodes for the U.S. Army's Warfighter Information Network-Tactical (WIN-T) program are now certified to use the Ka-band frequency to send video, multimedia, imagery and data over the Wideband Global SATCOM (WGS) network.

Certification by the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command (SMDC/ARSTRAT) ensures the antennas meet stringent performance and operational control requirements needed to operate on the WGS network. The WGS network comprises a constellation of six U.S. Department of Defense satellites that enable increased communications capacity, connectivity and flexibility for U.S. military forces.

Working under a contract with the U.S. Army that began in 2009, SATCOM Technologies installed nine 9.2-meter antennas and ancillary communications equipment designed to operate in either Ku-Band or Ka-Band at three WIN-T RHN sites at Ft. Bragg, North Carolina; Camp Roberts, California and on the Island of Guam. The recent ARSTRAT testing enables four of the 9.2-Meter antennas to operate over Ka-band for access to the WGS network. At the same time, but under a separate contract, SATCOM Technologies upgraded an additional 9.2-meter Ku-band antenna to operate over Ka-band at WIN-T RHN in Landstuhl, Germany. That antenna has also been authorized to operate with the WGS satellites. All of the antennas and their pedestals were designed and manufactured at SATCOM Technologies' San Jose, California facility.

Use of Ka-band provides enhanced communications capabilities including:

  • Higher data-rate throughput
  • Additional SATCOM spacecraft options via the use of WGS satellites
  • Reduced space segment cost through access to WGS

The WIN-T RHNs serve as communications transport centers providing satellite, voice and data services to support forces as they move into a theater of operations and enable deployed units to connect to Defense of Department networks. One RHN can accommodate the network traffic of up to three U.S. Army divisions.

Commenting on the certification, Marvin Shoemake, vice president of Sales for SATCOM Technologies said, "Successful completion of ARSTRAT testing for Ka-band represents a major improvement for the WIN-T RHN program. And, because ARSTRAT is a type certification, it also enhances the utility of SATCOM Technologies' 9.2-meter platforms for other government agencies which may require communications over the WGS network."
