What is SATCOM used for?
Satcom refers to the voice and data service that allows an aircraft to communicate, via satellite, with air traffic control and its airline operations centre when outside coverage of conventional ground radar and Very High Frequency (VHF) stations.
What is Cobham SATCOM?
Cobham SATCOM (formerly Thrane and Thrane) is a leading manufacturer of satellite and radio communication terminals and earth stations for land, marine and airborne applications. Cobham’s SAILOR and EXPLORER ranges enable people to stay in touch on land and at sea, even in the most challenging environmental conditions.
What is UHF SATCOM?
The Ultra High Frequency Satellite Communications (UHF SATCOM) System provides communication links, via satellite, between designated mobile units and shore sites worldwide. The UHF SATCOM system is one of three SATCOM systems installed and operates in the UHF range.
What is BLoS SATCOM?
Airborne platforms can leverage local line-of-sight BLoS Airborne SATCOM Systems microwave links where infrastructure is available, but when it’s not, or when it’s blocked by mountains or buildings, SATCOM plays a critical role in connecting aircraft. …
What is SATCOM and how does it work?
Satcom (which stands for “satellite communication”) was an artificial geo-stationary satellite that facilitated wide-area telecommunications by receiving radio signals from Earth, amplifying them, and relaying them back down to terrestrial receivers.
Who uses SATCOM?
Delivering satellite communications solutions for government and military operations. Satcom Direct Communications (SDC) provides government and military users with aeronautical, land-mobile, and maritime satellite communications using Inmarsat, Iridium, and Ku-band services.
Who owns Cobham Satcom?
Advent International
January 2020 saw the formation of Cobham SATCOM Group (Cobham SATCOM) as a stand-alone business in the Cobham Group under the ownership of Advent International.
What frequency is satcom?
Satellite Communication (satcom) is based on a specific range of frequencies. The useable radio spectrum ranges from 1Ghz to 300Ghz, where its use for communications ends as the signal becomes infrared, X-Ray and visible light. For maritime satcom, we use the frequencies from 1Ghz up to approx. 30Ghz.
How do Satcom radios work?
A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals through a transponder. It basically creates a communication channel between a source transmitter and a receiver at different locations on earth.
What is beyond line-of-sight communications?
Beyond line-of-sight (BLOS) is a related term often used in the military to describe radio communications capabilities that link personnel or systems too distant or too fully obscured by terrain for LOS communications.
How do satellite ground stations work?
What are Satellite Ground Stations? The crew at these stations send radio signals to the satellite (uplink), receive data transmissions from the satellite (downlink), and in some cases, serve as command and control centers for the satellite network.
How much data can a satellite transmit?
For consumer satellite Internet, the allowance can typically range from 200 MB per day to 25 GB per month. A shared download carrier may have a bit rate of 1 to 40 Mbit/s and be shared by up to 100 to 4,000 end users.
