The week of April 20, 2026, features a diverse array of seven space missions across four countries, including the launch of the GPS III SV10 satellite with a groundbreaking laser communications demonstration, multiple Starlink deployments by SpaceX, and South Korea's first complete orbital flight of its solid-fuel launch vehicle. Additionally, Russia will conduct a Progress resupply mission to the International Space Station, marking a busy period in the global space launch schedule.
The most valuable insight for you is the first-ever demonstration of laser communications from a GPS satellite at medium Earth orbit via the Tesat-Spacecom SCOT80 optical communications terminal on the GPS III SV10 mission. This technology aims to replace the existing radio-frequency architecture with optical crosslinks capable of updating the entire GPS constellation simultaneously from a single ground station, offering significant advancements in satellite communication efficiency and security.
