What frequency is WGS?
WGS system provides 4.875GHz instantaneous switchable bandwidth. Around 500MHz of X-band and 1GHz Ka-band spectrum is allocated to WGS. Each satellite of WGS system provides 2.1Gbps to 3.6Gbps of data transmission rates, based on the mix of ground terminals, data rates and modulation schemes employed.
How many WGS satellites are there?
The on-orbit WGS constellation is comprised of six satellites in geosynchronous orbit.
What is a wideband satellite?
Wideband Global SATCOM (WGS) is a satellite communication system used by the US Military (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence. WGS augments the one-way Global Broadcast Service (GBS) through a new two-way Ka-band service.
Who built WGS satellites?
Boeing Satellite Development Center
The primary contractor for the satellites themselves is Boeing Satellite Development Center, which is building them around the Boeing 702HP satellite bus.
How much does a WGS satellite cost?
Congress inserted $600 million into the 2018 budget to pay for two satellites but appropriators did not add any funds for launches. WGS-10 alone cost $424 million. Launches cost on average $200 million to $300 million each.
Is WGS84 an ellipsoid?
WGS84 is made up of a reference ellipsoid, a standard coordinate system, altitude data, and a geoid. The error of WGS84 is believed to be less than 2 centimeters to the center mass.
How many Milstar satellites are there?
There are five operational Milstar satellites.
Where is the Optus C1 satellite?
The Optus C1 satellite is located at 156° East.
What is wgs8?
USA-272, or Wideband Global SATCOM 8 (WGS-8) is an United States military communications satellite operated by the United States Air Force as part of the Wideband Global SATCOM programme. Launched in 2016, it was the eighth WGS satellite to reach orbit. WGS-8 was procured by the United States Air Force.
What can whole genome sequencing reveal?
Whole-genome sequencing can detect single nucleotide variants, insertions/deletions, copy number changes, and large structural variants. Due to recent technological innovations, the latest genome sequencers can perform whole-genome sequencing more efficiently than ever.
Is WGS a datum?
Horizontal datums precisely specify each location on Earth’s surface in latitude and longitude or other coordinate systems. For instance, NAD27, NAD83, and WGS84 are examples of geodetic datums.
Is WGS 84 lat long?
The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory. The WGS 84 datum surface is an oblate spheroid with equatorial radius a = 6378137 m at the equator and flattening f = 1/298.257223563.
What is the Wideband Global SATCOM system?
The Wideband Global SATCOM (WGS) system is a high-capacity communication satellite, previously known as the wideband gap filler satellite system. It is principally designed and developed for the US Department of Defence (DoD).
What is the DoD wideband satellite communication system?
The system is composed of the Space Segment satellites, the Terminal Segment users and the Control Segment operators. DoD wideband satellite communication services are currently provided by a combination of the existing Defense Satellite Communications System (DSCS) and Global Broadcast Service (GBS) satellites.
What is a directwgs satellite?
WGS systems feature digitally channelised transponder satellites that provide communication capacity, connectivity and flexibility to the US military forces. These satellites operate in the programmed X- and Ka-band frequency spectrum.
What is a WGS satellite?
The U.S. Department of Defence selected Boeing Space Systems in 2001 for the WGS satellites as a replacement for the Defense Satellite Communications System 3 in operation from the 1980s into the 2000s.
