Intelsat 37e

Wiki

Intelsat 37e was built by Boeing (Hughes) and is based on the BSS-702MP platform. It will be powered by two solar wings, each with three panels of ultra triple-junction gallium arsenide solar cells. With a service life of 15 years, the satellite will use C-band, Ku-band, and a steerable Ka-band capacity that will allow it to replace the Intelsat 901 spacecraft currently operating in the 18 degrees E location that Intelsat 37e will set up shop.

Wiki

BSAT-4a sports 24 Ku-band transponders and will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition. Based on the SSL 1300 platform, the satellite is designed to provide service for 15 years or longer, adding to B-SAT’s three other satellites, BSAT-3a, BSAT-3b, and BSAT-3c, although they are currently providing a 2K broadcasting service. B-SAT has started 4K/8K test broadcasting from the BSAT-3 series and will provide a new service, 4K/8K regular broadcasting service by BSAT-4a starting in December 2018.
