Problem
Current satellite communications rely on simple bent‑pipe links that merely relay data without intelligent routing, leading to inefficient bandwidth use, high latency, and limited scalability for emerging space‑based internet services.
Solution
Ephemeris Net develops a dedicated networking layer for space assets that defines how data is routed, prioritized, and transmitted across orbital constellations. By implementing protocols optimized for the dynamics of low‑Earth orbit and geostationary networks, the platform enables high‑capacity, low‑latency links between satellites, ground stations, and user terminals. The infrastructure supports dynamic path selection, congestion management, and fault tolerance, allowing service providers to build reliable space‑internet offerings without redesigning each satellite payload. Integration is provided through standardized APIs and software‑defined networking components that can be deployed on existing satellite platforms, accelerating the rollout of next‑generation space connectivity.
Target Audience
Primary customers are satellite operators, space‑based internet service providers, and defense agencies that require scalable, high‑performance networking for constellations of communication satellites.
Features
- Space‑optimized routing protocols that account for orbital mechanics, Doppler shift, and intermittent connectivity
- Software‑defined networking (SDN) control plane for real‑time path selection and bandwidth allocation across constellations
- Built‑in congestion control and quality‑of‑service (QoS) mechanisms to guarantee latency‑sensitive traffic
- Fault‑tolerant link management with automatic rerouting around failed nodes or adverse space weather conditions
- Open APIs and SDKs for seamless integration with satellite payloads, ground stations, and terrestrial network operators
