Non-Terrestrial Networks (NTN)

Don't let legacy VSAT isolate your network

Raemis™ 3GPP Rel-17+

The NTN Core Platform

Druid Software provides market-leading 3GPP-compliant Raemis™ core network software engineered specifically for Non-Terrestrial Network (NTN) operators and sovereign satellite infrastructure. As the most widely deployed NTN cellular core platform in the market, Raemis easily scales to support hundreds of millions of subscribers while guaranteeing complete data sovereignty and operational independence.

Platform Architectural Capabilities

Dual-Mode Broadband & IoT Convergence (5G NR + NB-IoT)

Raemis features a dual-mode 4G EPC and 5G Core engine on a unified cloud-native platform. It concurrently processes Data over NAS (DONAS) and Non-IP Data Delivery (NIDD/NEF) for IoT endpoints while managing high-throughput 5G NR data, IMS voice and 3GPP Rel-18 Voice over NB-IoT sessions over shared satellite payloads.

Multi-Tenant Infrastructure Sharing & Global Roaming

Incorporates native Multi-Operator Core Network (MOCN) sharing and core network slicing with isolated User Plane Functions (UPFs). Satellite operators can operate as a centralized core broadcasting partner PLMNs or integrate seamlessly with MNOs via 3GPP standard N2, N3 and S1 interfaces and SEPP gateways.

Distributed Edge & Feeder-Link Optimization (CUPS)

Decouples control signaling from user traffic using Control and User Plane Separation (CUPS). Core control functions (AMF/SMF/MME) are centralized in regional clouds while lightweight edge UPFs deploy directly at teleport gateways for local internet breakout, minimizing latency and feeder-link congestion.

Flexible Deployment & Hardware-Agnostic Silicon Freedom

Built on a lightweight, containerized architecture that runs transparently at ground stations or regeneratively on satellite payloads. Software is ported to efficient ARM, RISC-V, and x86 architectures under Yocto Linux, optimizing power consumption for spaceborne hardware.

Core Network Solutions for Non-Terrestrial Network Operators

Key Differentiators for Sovereign NTN Operators

  • Most Widely Deployed Core: Trusted globally with active deployments across commercial, public safety, enterprise, and non-terrestrial networks.
  •  Store & Forward Signaling: Buffers signaling messages during LEO satellite hand-offs and feeder link reconnections to ground stations, ensuring uninterrupted session continuity.
  • Inbound & Outbound Roaming: Enables terrestrial cellular subscribers to seamlessly connect to sovereign satellite coverage in remote locations via 3GPP SEPP gateways and T7 interfaces.
  • Multi-Operator Core Network (MOCN): Enables multiple defense branches, public safety agencies, or commercial mobile operators to securely share non-terrestrial radio access infrastructure.
  • Next-Gen Voice over NB-IoT: Actively collaborating with innovation partners to deploy 3GPP Release 18 Voice over NB-IoT, extending voice functionality over satellite data networks.

Secure Your Sovereign NTN Infrastructure

Store & Forward Signaling

Buffers signaling messages during LEO satellite handoffs and feeder link reconnections to ground stations, eliminating session drops and ensuring continuous user connectivity.

Global IPX / Roaming Interconnect

Supports standard IPX/GRX clearinghouse interfaces, 3GPP SEPP gateways, and dynamic PLMN ID broadcasting, letting visiting subscribers roam automatically onto satellite coverage.

Autonomous Subscriber Authority

Maintains total authority over subscriber credentials and provisioning via local or geo-redundant Master Subscriber Databases (HSS/UDM) guaranteeing complete data sovereignty.

Mission-Critical Quality of Service

Granular 5QI policy controls, REST APIs, and native MCPTT/MCData support ensure deterministic traffic prioritization for maritime, defense, and emergency sector operations.

Platform Architecture & Hardware Agnostic Scale

Massive Cloud-Native Scalability

  • Scales to Hundreds of Millions: Built on an architecture of cloud-native, stateless network functions that scale seamlessly from compact edge servers up to deployments supporting hundreds of millions of users.
  • Geo-Redundant Resiliency: Geo-redundant subscriber databases and distributed network function clusters protect against site failure while maintaining high-throughput performance.

 Complete Data Sovereignty

  • Localised Data Breakout (UPF): Keep critical user plane traffic strictly within national borders or secure private data centers using flexible local breakout options.
  • Autonomous Subscriber Database: Maintain total authority over subscriber credentials and provisioning via local or geo-redundant Master Subscriber Databases (HSS/UDM).

Transparent, Regenerative & Silicon Freedom

  • Transparent & Regenerative Cores: Centralize core functions at sovereign ground stations or deploy containerized core components directly on-board orbital satellite payloads.
  • ARM, RISC-V, & x86 Support: Software-only core ported to run efficiently on low-power ARM and RISC-V processors under Linux environments (including Yocto Linux) for low-power spaceborne or tactical edge hardware.
