Space-Grade Optomechanical & Positioning Systems
Complete optical assemblies are self-contained optical instruments designed to deliver a defined optical function as an integrated unit.
Custom alignment, motion control, and multi-axis positioning systems for mission-critical optical platforms.
Astravon develops custom optomechanical positioning solutions for space-grade optical components, assemblies, payload sensors, telescopes, and laser communication systems.
Our capabilities include hexapod positioning platforms, motion-controlled optical mounts, and integrated optical positioning systems for precise alignment, controlled movement, and long-term positional stability.
Each system is engineered around the mission’s optical tolerance, mechanical envelope, thermal environment, control architecture, and verification requirements.
What We Provide
Astravon designs and delivers custom optomechanical and positioning systems, including:
- 6-DOF positioning systems
- Hexapod positioning platforms
- Optical alignment and correction systems
- Motion-controlled optical mounts
- Tip-tilt, focus, translation, and rotational mechanisms
- Custom actuated optical assemblies
- Integrated optical positioning subsystems
- Sensor-assisted and closed-loop positioning solutions
Our hexapod platforms provide controlled positioning across six degrees of freedom for optical components, instruments, and payload assemblies. Systems can be developed for ground alignment, in-orbit adjustment, active calibration, or controlled repositioning during mission operation.
Astravon also develops motion-controlled mounts for mirrors, lenses, detectors, beam-steering elements, and other precision optical hardware. Depending on the application, the mount may integrate actuators, position sensors, flexures, bearings, locking features, control electronics, and mechanical interfaces.
The result is a complete optical positioning solution designed to deliver precise alignment, repeatable motion, predictable control, and positional stability.
Optical Positioning System Capabilities
Astravon develops positioning architectures for applications requiring translation,tip-tilt, focus, clocking, or multiple coupled degrees of freedom.
Depending on the mission, this may include:
- Coarse and fine positioning stages
- Multi-axis kinematic control
- Hexapod-based optical alignment
- Active mirror or sensor positioning
- Focus and boresight adjustment
- Beam-steering and pointing mechanisms
- Position feedback and closed-loop control
- Launch-lock or hold-down features
- Redundant or low-power operating concepts
The mechanical and motion-control architecture is developed directly from the optical tolerance budget. Actuator resolution, structural compliance, sensor accuracy, thermal drift, control logic, and optical sensitivity are evaluated at the system level.
Engineering Focus
Our systems are developed to meet mission-specific optical, mechanical, environmental, and control requirements, including:
- Alignment accuracy
- Motion resolution
- Repeatability
- Positional stability
- Optical line-of-sight stability
- Thermal behavior and drift
- Structural stiffness
- Launch vibration and shock resistance
- Vacuum-compatible material and lubricant selection
- Actuator and sensor integration
- Cable routing and electrical interfacing
- Verification and metrology planning
Astravon can support tolerance analysis, actuator selection, structural and thermal assessment, kinematic modelling, control-interface definition, prototype development, test planning, and qualification preparation.
Verification may include dimensional inspection, optical metrology, repeatability testing, stiffness measurement, thermal-vacuum evaluation, vibration testing, and functional performance testing before and after environmental exposure.
Typical Positioning Applications
Astravon supports positioning requirements including:
- 6-DOF alignment of optical assemblies and payload instruments
- Hexapod-based ground or in-orbit alignment
- Motion-controlled positioning of mirrors, detectors, and beam-steering elements
- Focus, tip-tilt, boresight, and optical path adjustment
- One-time deployment, periodic realignment, or closed-loop active control
Systems can be delivered as individual mechanisms or as integrated optical positioning subsystems with actuators, sensors, and control interfaces.
