Geostationary Transfer Orbit Launch Services
Browse 52 launch windows targeting Geostationary Transfer orbit. Compare rideshare slots, providers, and book your CubeSat deployment.
Geostationary Transfer Orbit (GTO) is an elliptical orbit used as the intermediate step to reach geostationary orbit (GEO) at 35,786 km altitude. GTO launches are dominated by heavy-lift vehicles including SpaceX Falcon 9/Heavy, Arianespace Ariane 5/6, and ULA Atlas V, which deploy communications satellites and hosted payload missions requiring the stable 24-hour orbital period of GEO.
GTO rideshare opportunities are more selective than LEO rideshare, typically targeting hosted payload agreements where a secondary payload rides alongside a primary GEO comsat. Payloads in GTO must withstand high radiation environments in the Van Allen belts during the transfer phase, requiring radiation-hardened or tolerant electronics.
For organizations planning GEO communications or space domain awareness missions, GTO hosted payload programs provide a cost-effective alternative to dedicated GTO launches. NewSpace Market lists current GTO hosted payload opportunities, ride-share agreements, and provider contacts, allowing mission planners to evaluate options across multiple operators on a single platform.
