The challenge
Connectivity when
it matters most.
Modern organisations increasingly depend on online services, cloud platforms and reliable communications for day-to-day operations.
Severe weather, infrastructure failure and unexpected incidents can reduce the availability of terrestrial networks at precisely the point they are most needed. Remote locations and temporary operations can present the same problem for a different reason: suitable connectivity may simply not be available.
Resilient Multicom is being developed as a deployable communications platform that brings together terrestrial and satellite networks to provide alternative communications paths when reliance on a single network is not enough.
Communications Resilience
Reduce reliance on a single communications network.
Combine terrestrial and satellite connectivity within one managed platform.
Flexible Deployment
Take connectivity to where it is needed.
Support remote sites, incident response, temporary operations and high-demand environments.
System architecture
One platform. Multiple
communications paths.
Resilient Multicom brings together multiple communications technologies within a single deployable platform.
Satellite bearers in Low Earth Orbit and Geostationary Orbit complement available terrestrial networks. The platform can then provide local connectivity through services including Ethernet, Wi-Fi and private 5G.
At the core of the system, established routing technology handles network traffic and bearer failover, while the AmbaSat Gateway provides the supervisory and orchestration layer above it.

Gateway role
Supervisory intelligence
above the routing layer.
AmbaSat is developing the Gateway and associated interface and control functions for Resilient Multicom.
The architecture deliberately separates network routing from system supervision.
The Peplink MBX provides WAN/LAN routing, standard network services and bearer failover execution. Above it, the AmbaSat Gateway maintains a wider view of system state, bringing together monitoring information, orchestration policy and operational evidence.
This allows the Gateway to understand what communications resources are available, determine the appropriate action and request changes through the routing platform while maintaining a record of what happened and why.
Gateway orchestration loop
Monitor. Decide. Act. Record.
Monitor
Observe bearer availability, router state, local-service status and selected platform information.
Decide
Apply policy using communications availability, service priority, link condition and relevant system state.
Act
Request routing, priority, recovery or authorised control actions.
Record
Capture decisions, alarms, faults, operator actions and recovery evidence for later review.
The evidence trail is being treated as a core part of verification rather than simply a diagnostic log. Integration testing is intended to demonstrate both system behaviour and the evidence behind that behaviour.
Bearer diversity
Resilience through diversity
of communications paths.
No single communications bearer can be assumed to provide the right service in every location or operational situation.
Resilient Multicom is therefore designed to combine LEO, GEO and terrestrial connectivity, allowing available communications systems to be used and prioritised according to operational requirements.
Rather than replacing terrestrial communications, satellite connectivity provides additional paths where terrestrial networks are unavailable, overloaded or disrupted.
Deployable platform
Deploy. Connect. Manage.
Resilient communications need to be practical to operate as well as technically capable.
The platform is designed for remote monitoring and management, allowing communications services to be deployed where conventional infrastructure is unavailable or where additional resilience is required.
The system concept includes remote configuration and management, with the deployable platform intended to operate with minimal intervention once established at a site.
Operational scenarios
Connectivity for demanding
and unpredictable environments.
Resilient Multicom is being developed around practical operational scenarios where communications availability directly affects the ability of organisations to continue operating.
Emergency Response
Provide a deployable communications hub where existing infrastructure has been damaged or disrupted.
Business Continuity
Restore access to cloud systems, online applications and communications following an unexpected network interruption.
Remote Operations
Extend resilient communications to locations where suitable terrestrial connectivity cannot be assumed.
Temporary Operations & Events
Add communications capacity for temporary sites, exhibitions, sporting events and other high-footfall environments where conventional networks may become constrained.
Development programme
Developing and validating
a deployable resilient
communications platform.
Resilient Multicom is being developed through the European Space Agency ARTES 4.0 programme by Inotec Solutions and AmbaSat.
The project began in March 2026 and has progressed through system definition, equipment selection, software development and platform development.
The AmbaSat Gateway architecture and principal Gateway/router boundaries are now defined for integration testing. Verification is progressing from component-level development towards integrated testing with the router, representative communications bearers, interface functions and wider platform.
The activity is ongoing. Demonstration, testing and validation with prospective users form part of the programme leading towards final reporting planned for March 2027.

Verification
From component development
to integrated verification.
Resilient Multicom is more than a connectivity demonstration. The programme is also establishing how system behaviour can be verified and evidenced.
For the AmbaSat elements, current verification activity covers the supervisory architecture, Gateway-to-router monitoring and control, bearer-state awareness, prioritisation and failover behaviour, and the logging of decisions, alarms, operator actions and recovery events.
Remaining platform-dependent interfaces are being closed as representative bearer equipment, power controls and final platform interfaces become available.
AmbaSat contribution
Gateway, orchestration
and interface technology.
AmbaSat's role within Resilient Multicom centres on the supervisory intelligence and supporting interface functions that bring the communications system together.
Gateway Core
Supervisory orchestration, system-state awareness and local/remote Gateway management.
Monitoring & Policy
Aggregation of system information and policy-driven communications decisions.
Operational Evidence
Logging of events, decisions, alarms, operator actions and recovery activity.
Interface & Control
Supporting hardware and interfaces where required for functions that cannot be provided directly through the routing platform.
Routing execution remains within the Peplink MBX, while wider trailer and platform integration is led by Inotec Solutions.
Project ecosystem
Combining communications,
satellite and systems expertise.
Resilient Multicom brings together expertise in deployable communications platforms, satellite connectivity, network routing, system integration and intelligent orchestration.
Inotec Solutions is developing and integrating the wider deployable platform.
AmbaSat is developing the Gateway, orchestration software and associated interface/control functions.
The programme is supported through ESA ARTES 4.0.

Building resilience into
communications infrastructure.
Organisations increasingly depend on connectivity in environments where a single terrestrial network cannot always be relied upon.
AmbaSat is developing orchestration and Gateway technologies that combine satellite and terrestrial communications into resilient, manageable systems.
If your organisation operates in remote locations, supports emergency response, manages critical infrastructure or requires resilient temporary communications, we would welcome the opportunity to understand your requirements.
