Mission Brief

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.
