The military has 10 wideband global satcom WGS satellites for the provision.

Global hawk ku band satcom. Northrop to Retrofit Global Hawk March 28 2016. Under this task order UltiSat will provide the United States Air Force USAF Air Combat Command ACC with commercial Ku-band satellite capacity for. The aircraft data link system is designed to work with Ku-band satellite spot beams to minimize size weight and power requirements for the airborne SATCOM system.

Under this contract UltiSat will provide commercial Ku-band satellite capacity with coverage of the Continental United States CONUS Atlantic and Pacific areas of operation. In August and November 1999 the USN demonstrated a phased array antenna that can handle both satcoms and CDL operation. The bulge at the top front surface of the fuselage which gives Global Hawk its distinctive appearance houses the 48in Ku-band wideband satellite communications antenna.

UAVs Drive SATCOM Modernization. Global Hawk is an unmanned high altitude long endurance air vehicle. 108 MHz Ku-band capacity supporting USCENTCOM AOR.

The most common maritime VSAT band in use Ku-band satellite coverage has grown along the commercial trading routes making it a global VSAT alternative to C-band for merchant vessels. CTC0346 Global Hawk GH Airborne Intelligence Surveillance and Reconnaissance AISR COMSATCOM Support Request for Proposals RFP predicted in-service Date. Reserved for government and naval use only X-band offers similar throughput potential as C- and Ku-band and good resistance to rain fade.

Navys Broad Area Maritime Surveillance BAMS program and another user of vital bandwidth. Very Small Aperture Terminal VSAT. I n t e g r i t y - S e r v i c e - E x c e l l e n c e 10.

UltiSat will support GH Ku-band earth terminals associated with the Global Hawk Mission Control Element which may be located at any of several locations in California. The growing use of unmanned aerial vehicles UAVs like Predator and Global Hawk aircraft is making military communications satellite bandwidth a vital part. Supports USCENTCOMs SWA network architecture and contingency mission requirements.

UltiSat will support GH Ku-band earth terminals located in the 48 contiguous United States. Air Forces Global Hawk unmanned air vehicle training and operations. UHFVHFCDL GENERAL DESIGN Mission Control Element MCE Launch and Recovery Element LRE Common Ground Segment.

Frequencies utilized were in. Figure 1a is the current communication deployment. The Global Hawk program has its origins in the 1995 High-Altitude Endurance Unmanned Aerial Vehicle Advanced Concept Technology Demonstration HAE UAS ACTD program initiated by DARPA Defense Advanced Research Projects Agency and DARO Defense Airborne Reconnaissance Office.

The Northrop Grumman MQ-4C Global Hawk will be the centerpiece of the US. The full fleet is to scheduled to have Ka-band capability by 2027. A Ku-band terminal is located at Dryden Research Center DRC with a fiber optic run between the ground station and the.

Therefore both the UAV and its supporting earth terminal must operate within the satellites spot beam 1500 NM diameter coverage during Ku-band SATCOM. With significant bandwidth available Ku-band. It is not designed nor adequately powered to operate with earth-coverage beams.

The system is capable of both direct line of sight communications with the ground station by a common data link or beyond line of sight through Ku band SATCOM direct line of sight capability good support up to 274 megabits per second although this is not currently supported and 50 megabits per second by a Ku band SATCOM. Under this task order UltiSat will provide the United States Air Force USAF Air Combat Command ACC with commercial Ku-band satellite capacity for Global Hawk GH Unmanned Air Vehicle UAV operations and training. UltiSat has received a potential 81 million task order from the Defense Information Systems Agency to provide Ku-band satellite coverage for the US.

UltiSat will support GH Ku-band earth terminals located in the 48 contiguous United States. Figures 1a b and c illustrate three possible deployment scenarios for Ku-Band satellite communication. Under this task order UltiSat will provide the United States Air Force USAF Air Combat Command ACC with commercial Ku-band satellite capacity for Global Hawk GH Unmanned Air Vehicle UAV operations and training.

Data is transferred by Ku-band satellite communications X-band line-of-sight links and both Satcom and line of sight links at UHF-band. Satellite links when considering communication between the Global Hawk payloads and the Principle Investigators.
