What is multi-orbit networking?
Multi-orbit networking refers to architectures that combine satellites from multiple orbital regimes — LEO, MEO, and GEO — into a single, unified network infrastructure. Rather than choosing one orbit for all applications, multi-orbit systems route traffic to the optimal layer based on application requirements: low-latency LEO links for real-time applications, high-capacity GEO links for broadcast distribution, and MEO for balanced throughput and latency at intermediate cost.
Business drivers
No single orbit is optimal for all use cases. A maritime vessel needs ultra-reliable safety communications (Inmarsat L-band GEO), high-throughput crew internet (LEO Starlink or Ka-band HTS GEO), and IoT sensor connectivity (Iridium L-band LEO). An aeronautical operator wants low-latency passenger internet (LEO) combined with a resilient safety fallback (GEO SATCOM). Multi-orbit enables a single network provider to address all of these from one platform with dynamic policy-based routing.
Technical implementation
Multi-orbit terminals integrate multiple antenna systems (or a single reconfigurable antenna) capable of communicating with different satellite types simultaneously. Software-defined wide area networking (SD-WAN) manages the multi-link environment, applying Quality of Service (QoS) policies that route latency-sensitive traffic over LEO, cost-sensitive bulk data over GEO, and use MEO as an intermediary layer. Operators like Viasat (after the Inmarsat acquisition), SES, and Eutelsat all have multi-orbit strategies. SES' 'industry-first multi-orbit solution' brands itself as seamless LEO+GEO integration.
