SWISSto12 Deploys 5-Meter Deployable Antenna for Direct-to-Device Broadcast from GEO Satellites
2026-05-06
Swiss satellite communications company SWISSto12 has signed a contract with German space subsystem consortium HPS/LSS to manufacture a large deployable reflector subsystem for the NEASTAR-1 mission. The reflector, with a diameter of 5 meters, operates in the L-band and will be deployed in orbit after launch, integrated with SWISSto12's HummingSat small GEO satellite platform. The mission aims to achieve direct-to-device media broadcasting from a single geostationary orbit, replacing distributed low Earth orbit constellation solutions. The project is jointly funded by the European Space Agency, the German Aerospace Center, and the EU's Horizon 2020 program, aiming to strengthen European end-to-end space system capabilities. The combination of the HummingSat platform with a large deployable L-band reflector creates a new category of space systems for direct-to-device services, enabling operators to obtain critical wide-coverage network capabilities without relying on large satellite constellations. HPS/LSS joins SWISSto12's German supply chain network, including companies such as ASP, AST, and DLR, and this collaboration demonstrates how European industrial cooperation can support next-generation connectivity technologies.

SWISSto12部署5米可展开天线，实现GEO卫星直连设备广播
瑞士卫星通信公司SWISSto12与德国空间子系统联合体HPS/LSS签约，为NEASTAR-1任务制造大型可展开反射器子系统。该反射器直径5米，工作在L波段，发射后在轨展开，将与SWISSto12的HummingSat小型GEO卫星平台集成。任务目标是从单颗地球静止轨道实现直接面向设备的媒体广播，替代分布式低轨星座方案。该项目由欧空局、德国航天局及欧盟“地平线2020”计划共同资助，旨在强化欧洲端到端空间系统能力。HummingSat平台与大型可展开L波段反射器结合，开创了面向直接到设备服务的空间系统新类别，运营商无需依赖大型卫星星座即可获得广覆盖关键网络能力。 HPS/LSS加入SWISSto12德国供应链网络，包括ASP、AST、DLR等企业，此次合作体现了欧洲工业合作如何支撑下一代连接技术。
