Rugged Accelerometers for Defense Systems and Navigation Platforms
Silicon Designs’ defense accelerometers are trusted across ground, air, and maritime systems to deliver consistent motion sensing under shock, vibration, and real-world field conditions.
Built for Mission-Critical Sensing Across Defense Platforms
SDI accelerometers provide the reliability, precision, and mechanical resilience required for modern defense applications, including missile stabilization, vehicle health monitoring, and embedded sensing in inertial navigation systems. These sensors are used in both developmental testing environments and fully deployed military platforms.
Applications include:
- Missile flight stabilization and GN&C subsystems
- Ground vehicle shock and vibration analysis
- UAV and drone platform motion sensing
- Navigation in GPS-denied environments
- Redundant sensing for avionics and inertial navigation
- Defense simulation and test equipment
- Impact and launch event logging
- Surveillance platform monitoring
- Long-range guided system diagnostics
- Tactical equipment development and validation
Dependable Performance in Defense and Tactical Applications
Defense programs require sensors that can be trusted across high-impact scenarios and dynamic operating conditions. SDI accelerometers are engineered to maintain consistent output in applications where reliability, survivability, and mission continuity are critical.
Rugged Construction for High-G and Field Deployment
With durable packaging and shock-tolerant MEMS structures, SDI accelerometers perform reliably in ballistic, airborne, and vehicle-mounted systems subject to extreme acceleration and vibration profiles.
High Accuracy for Navigation and Control Systems
SDI sensors feature low noise and tight sensitivity tolerances, enabling precise motion detection in inertial navigation and GN&C systems, particularly where GPS access is intermittent or unavailable.
Reliable Output for Testing and Embedded Use
From test ranges to mission-ready deployment, SDI accelerometers deliver consistent signal integrity with minimal drift, supporting repeatable validation and real-time sensing in complex defense environments.
Reliable Accelerometers for Tactical and Navigation-Critical Systems
SDI MEMS DC accelerometers provide durable, low-drift motion data for defense platforms where shock, vibration, and mission-critical reliability are constant operational demands.
