Inmarsat 5 Satellite

Launched between 2013 2015 the constellation of three satellites covers the following regions.

Inmarsat 5 satellite.

In its stowed launch configuration the satellite is 6 98 meters high 3 59m wide and 3 27m long. Inmarsat owns and operates the world s most reliable l band satellite network. Each inmarsat 5 satellite will carry 89 ka band beams that will operate in geosynchronous orbit with flexible global coverage. The satellite will be a very high throughput satellite vhts providing capacity across the middle east europe and the indian subcontinent.

The inmarsat 5 f1 commercial communications satellite was built by boeing satellite systems for operation by inmarsat uk. The name inmarsat 5 f5 is conjectural. Inmarsat s fifth global xpress satellite gx5 was launched by arianespace from the guiana space centre in kourou french guiana on 26 november 2019. The inmarsat 5 satellites are based on boeing s 702hp high power satellite platform that is capable of hosting powerful communications payloads with payload power of up to 18kw with state of the art onboard systems including precise pointing capability and the use of flight proven components and built in redundancy to ensure the satellite meets its in orbit lifetime of 15 years.

The satellites are designed to generate approximately 15 kilowatts of power at the start of service and approximately 13 8 kilowatts at the end of their 15 year design life. Each inmarsat 5 series global xpress satellite carries 89 fixed and six steerable spot beams in ka band. With the arrival of 5g satellite communications will play an important part in transforming the way we live and work by extending coverage and new capabilities into the seas the skies and rural and remote areas to power an always on global digital society.

Inmarsat 5 hcp high elevation altitude satcom link elevation contours at the 2 degree elevation contour blue lines in graphic for an aircraft at 60 000 feet altitude the peak latitude is 83 66 degrees on this contour line at this altitude the atmosphere is thin since the los line to the satellite never goes below 40 000 feet this means. The company s earlier satellites broadcast in l band but inmarsat switched to ka band for the global xpress system offering improved downlink communications speeds to 50 megabits per second with up to 5 megabits per second on the uplink side. The inmarsat 5 i 5 satellites power our high speed global xpress broadband service.
