Mission description

GovSat-2 is the second satellite for GovSat, the public-private partnership between SES and the Luxembourg government. The satellite is designed to address the needs of defense users at the highest Security and Service Assurance Level, adding new ultra-high frequency (UHF) channels in the X- and military Ka-bands, and will include other security features such as dedicated hardening, an advanced anti-jamming system, and embedded geo-location. GovSat-2 will be positioned over the European satellite arc, joining GovSat-1 in augmenting reliable connectivity services for government customers over the region. The satellite will be built by Thales Alenia Space on its Spacebus 4000B2 platform.

Guiana Space Centre, French Guiana

The Guiana Space Centre is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
