Intelsat 31 (DLA 2) is a commercial communications satellite of the International Telecommunications Satellite Consortium ( Intelsat ) based in Luxembourg .
It was placed in geostationary orbit on June 9, 2016 at 7:10 UTC with a Proton-M / Bris-M launcher from the Baikonur rocket launch site . The start was actually planned a day in advance, but had to be postponed due to technical problems with the electrics of the ground systems. At the start, a Proton missile in the improved version 8К82КМ (phase IV) was used for the first time. In this, composite materials and lighter but more stable aluminum structures and a lighter telemetry system are used in the upper level, which should increase the payload in the geostationary orbit by 150 kg. 9 minutes and 41 seconds after the launch, the payload with the Bris-M upper stage was separated from the rocket and after 15 hours and 30 minutes and five burning phases of the upper stage the satellite was in an elliptical transition orbit between 3503 and 65,000 kilometers above the earth and one Inclination of exposed at 29.6 °. The Russian news agency Interfax reported that one of the four engines of the second stage of the Proton rocket switched off nine seconds too early, which had to be compensated for by the first burning phase of the Bris-M upper stage being 30 seconds longer.
The three-axis stabilized satellite with 72 Ku-band - and 4 C-band - transponders fitted to and from the position 95 ° from West Latin and North America provide telecommunications services and television. There it will complement the Intelsat 30 and Galaxy 3C satellites, which are deployed in the same position . The entire Ku-band of Intelsat 31 is operated by DirecTV Latin America in order to expand its television offerings and to offer backup and recovery capacity. The four C-band transponders for Intelsat's C-band infrastructure operate with downlink frequencies between 3400 and 3700 MHz and offer a large area of coverage over Latin America and the entire USA and parts of Canada . The satellite was built on the basis of the SSL 1300 satellite bus from Space Systems Loral (SSL) and has a planned service life of more than 15 years. For a functional test, the satellite was first brought to a position of 132 ° west.
