Шаблон:Short description Шаблон:Infobox spaceflight
The Amazonas 5 is a Spanish commercial communications satellite developed by SSL and operated by Hispasat. Launched on Шаблон:Start date, it has an expected service life of 15 years. Its orbit allows it to cover all of South America,[1] allowing for broadband and broadcast services. It replaces the Amazonas 4A and 4B satellites, the former of which experienced a performance loss and the latter which was cancelled.[2]
Design
Satellite bus
The satellite is based on the SSL 1300, a satellite bus produced by SSL. It has a launch mass of Шаблон:Cvt and has two deployable solar panels.[1][2]
Propulsion
The satellite uses a chemical propulsion system for orbit raising with the main engine providing a force between 450 and 490 N and several altitude control thrusters. Although the SSL 1300 spacecraft bus can be equipped with an electric propulsion system, it is unknown if Amazonas 5 comes with it.[3]
Communications
The satellite's communication system is its main payload. It consists of 24 Ku band transponders for its South America beam and 34 Ka band spot beams for its Brazil beam.[1] It can provide broadband and television services and can deploy 3G, LTE, and 5G networks.[2]
Launch
Amazonas 5 launched from Baikonur Cosmodrome Site 200, Kazakhstan, on Шаблон:Start date, on board a Proton-M Breeze M rocket. The launch was initially slated to happen on 9 September instead but the Proton rocket's arrival from Moscow was delayed.[4]
It was launched to a geostationary orbit with a periapsis of Шаблон:Cvt, an apoapsis of Шаблон:Cvt, and orbital inclination of 0.0°. It is placed at a longitude of 61° W in order to serve South America. It would provide internet connectivity to around 500,000 people in the region, and opens 500 new television channels.[5]
