FOCUS — COTM Challenges, by Peter Woodhead
There are many X-band and Ku-band satellite tracking antennas for On-The-Move (OTM) applications, but only a few products have been developed for Ka-band. With the deployment of the Wideband Gapfiller Satellites (WGS) the demand for OTM Terminals at Ka-band will increase.
FOCUS — Network Management, The Next Step, by Wally Martland
Most of the Network Management Systems (NMS) solutions on the market today evolved out of Monitor and Control (M&C) solutions. Operators at an Earth station relied on the M&C system to monitor and control one or more antennas’ RF equipment without having to walk amongst the racks in order to determine if there was a failure on any piece of equipment. As network operators acquired or built out more infrastructure to meet the ever growing demand for bandwidth from their customers, M&C systems were forced to evolve into the NMS solutions on the market today.
FOCUS — Military Satellite WANS—How To Optimize, Accelerate + Provide Interoperability, by Gordon Dorworth
There are many operational and environmental conditions which adversely affect military satellite communications, impairing network performance and consuming valuable bandwidth. While satellite communications enable mobility and communications in remote locations, satellite-based Internet connectivity suffers due to adverse weather, interference, high-latency and transport and application protocol inefficiencies.
FOCUS — A Spatial Router, by Laurence Cruz
Cisco Systems wants to put a router on every communications satellite — the networking giant has already sent the first one into space. The company announced today that the router has successfully completed initial in-orbit tests, after being launched November 23 aboard the Intelsat 14 communications satellite into geosynchronous orbit, 22,300 miles above the Earth.
INTEL — BGAN Software Defined Radio (SDR) breakthru, by Claus Krohn Vesterholdt
A complete SDR-based BGAN radio was successfully demonstrated at the SDR Forum Conference and Exhibition 2009 in Washington D.C. in December. The demo revealed the result of the joint SDR program completed by GateHouse, Inmarsat, and Spectrum Signal Processing by Vecima (Spectrum) and gave evidence that BGAN SDR-based satellite communication (SATCOM) is an opportunity readily at hand for manufacturers of military radios.
TECH OPS — We've Come A Long Way To Get To PCMA, by ViaSat
A principal objective of recent U.S. Department of Defense telecommunication transmission policy is to simplify its integrated wireless networks. To reach that objective, DoD policy includes a reduction in the number of available wireless waveforms and corresponding network hardware.
TECH OPS — Amplification — Meeting Those Demanding Ka-band Requirements..., by Stephen Turner
Historically there have existed far fewer choices for Ka-band amplifier products than their lower frequency counterparts. Factor in military grade Ka-band amplifiers and the selection becomes even more scarse. Paradise Datacom has released a new family of Ka-band LNAs and SSPAs that build upon their tradition of highly reliable SatCom amplifier products. These products are suitable for deployment in demanding military applications such as Wideband Gapfiller Satellite (WGS) terminals.
TECH OPS — SATCOM Uplink HPAs — Linear Power... What It Means..., by Comtech Xicom
All satellite communications links are subject to uncertainties and variations in equipment, environmental and atmospheric effects, and random variables that make satellite communications link design as much art as science. While tools are available for developing link budgets, the decisions and assumptions that really determine link performance come from careful consideration of all aspects of the link itself.
