Mission Readiness
Confidence before
commitment
Mission logic, systems, procedures and
possible responses must be ready for the
encounter.
Digital twins + onboard sensing & perception
Turning spacecraft encounters into controlled, predictable outcomes.
Vimotek connects mission-specific digital twins with onboard sensing and perception to help operators ensure operational confidence, execute proximity operations and manage proximity events before and during missions.
Spacecraft Encounters
Operators face encounters they initiate — and encounters they do not control.
Operational contexts
Whether planned or unplanned, both contexts centre on the same operational challenge: understanding and managing relative behaviour between spacecraft in close proximity.
Proximity Operations
Intentional encounters with a defined objective.
Rendezvous, inspection, docking, servicing, logistics, assembly, debris handling, terminal events and robotics.
RPO
Proximity Events
Encounters the operator does not control.
Unexpected or ambiguous approaches, anomalous manoeuvres, interference and other nearby-object behaviour.
SSA / SDA
Operational demands
Spacecraft encounters place particular demands on readiness, effectiveness and resilience because outcomes depend on relative motion, close-proximity behaviour and limited room for correction.
Confidence before
Mission Effectiveness
Achieve the intended
outcome
Planned proximity operations must achieve
their intended objective precisely and
repeatably.
Mission Resilience
Preserve mission
objectives
The mission must remain effective when
conditions become unexpected or depart
from plan.
Spacecraft Encounter Capability
Three complementary systems
for controlled, predictable encounters.
Vimotek connects mission-specific digital twins with onboard sensing and perception to help operators develop and maintain readiness, execute proximity operations and manage proximity events.
Encounter systems
Digital Twin Platform
& Mission Environment
Orbittwin
Mission-specific digital twins for spacecraft encounters.
Model spacecraft, sensors, CONOPS and scenarios; validate mission logic and sensor/GNC behaviour, rehearse operations, evaluate alternatives and support planning before and during operations.
Multi-physics simulation · Synthetic sensor data · Contact physics · SIL/HIL · Scenario scripting
Onboard Sensing
& Perception System
Navcam
Onboard perception for precise proximity operations.
Target acquisition, tracking, characterisation and relative state estimation for rendezvous, inspection, docking, servicing and robotics.
Target acquisition · Target tracking · Characterisation · Relative state estimation
Onboard Sensing
& Perception System
Sentinel
Onboard awareness and assessment for proximity events.
Detect, monitor and assess nearby objects and anomalous proximity behaviour, enabling earlier understanding and response preparation.
Nearby-object detection · Behaviour monitoring · Object characterisation · Proximity assessment
Operational fit
Different mission situations create different operational needs. Vimotek systems can be used independently or combined to reduce development and integration risk, support better-informed decisions and strengthen mission readiness, effectiveness and resilience.
Preparing a complex spacecraft operation
- Need
- Confidence that mission logic, sensors, GNC, procedures and edge cases will work as intended.
- System
- Orbittwin
- Value
- Validate, rehearse realistic scenarios, compare alternatives and reduce development and integration risk.
When operations change after launch
- Need
- A way to evaluate new manoeuvres, software changes, anomalies or response options before committing.
- System
- Orbittwin
- Value
- Test alternatives in mission context and support better-informed operational decisions before implementation.
Rendezvous, inspection, docking and servicing
- Need
- Reliable relative perception and confidence in the operational approach.
- Systems
- Navcam + Orbittwin
- Value
- Support precise, repeatable proximity operations with onboard perception and mission-specific validation.
When another spacecraft approaches unexpectedly
- Need
- To understand what is happening, how the situation is developing and whether action may be required.
- Systems
- Sentinel + Orbittwin
- Value
- Detect and assess nearby-object behaviour, evaluate its significance and prepare an informed response.
Vimotek
Built around spacecraft encounters.

Engagement Pathways
Start where it fits your mission.
For commercial, institutional and defence missions where spacecraft encounters must be prepared for, executed and managed with confidence.
Co-develop
Develop capability
through programmes
Partner through European and national initiatives to define, develop and validate capability for spacecraft encounters.
Demonstrate
Validate capability
in mission context
Run a focused pilot, test flight or in-orbit demonstration to assess performance, workflows and mission fit.
Deploy
Deploy systems
in operational missions
Integrate Vimotek systems into commercial, institutional or defence missions, from individual spacecraft to constellations.
Fly with Confidence
Discuss your mission with us.
Whether you need to validate a mission concept, prepare a proximity operation or manage a proximity event around an in-orbit asset, Vimotek can help make spacecraft encounters safer, more predictable and better understood.
