A new Japanese satellite, BSAT-4a and built by Space Systems/Loral, has arrived in Kourou, French Guiana, to be readied for launch by Arianespace. The satellite will be used for DTH broadcasting over Japan, and this will include 4K and 8K transmissions during the Tokyo Olympic Games in 2020.
BSAT-4a has 24 Ku-band transponders and will expand the availability of advanced television services. The satellite is based on the popular SS/L 1300 platform, which provides the flexibility to support a broad range of applications and technology advances. It is designed to provide service for 15 years or longer.
B-SAT has started 4K/8K test broadcasting from the BSAT-3 series and will provide new service, 4K/8K regular broadcasting service by BSAT-4a starting in December 2018.
The plan is for the satellite to be partnered with Boeing-built Intelsat 37e for a flight on September 1st. Intelsat 37e arrived at Kourou about a week ago.
The two satellites combined have a weight of some 10,000 kgs which would make the launch one of the heaviest ever – and perhaps a record – for an Ariane lift.
