The satellite launch operator, Arianespace , reported that this launch is a record for the Arian-5 launch vehicle in terms of payload to geostationary orbit . Together with the EchoStar 18 satellite, the weight of two satellites at launch was 9840 kg, and with the addition of the weight of adapters of the ACU and Sylda 5 - 10 731 kg [2] .
The launch, scheduled for June 8, 2016, was postponed one day before the start due to the identification of problems in the fuel line through which cryogenic fuel was pumped from the ground tanks into the upper stage of the launch vehicle [3] [4] .
The re-launch attempt, which was originally scheduled for June 16, was postponed for another day to complete the work on replacing and setting up the launch pad equipment. A day later, on June 17, the start was interrupted due to poor weather conditions (strong wind at high altitudes) [5] .
The launch of the Ariane-5 launch vehicle took place on June 18, 2016 at 21:38 UTC from the ELA-3 launch complex at the Kourou cosmodrome. 42 minutes after launch, the BRIsat satellite was launched into a geo-transfer orbit with indicators of 263 × 35 758 km, inclination of 5.97 ° [1] [6] [7] [8] .
