From aerial drones to deep-sea AUVs, the ability to sense motion precisely and reliably is foundational in unmanned systems. Silicon Designs Inc. (SDI) MEMS DC accelerometers provide a proven solution for unmanned systems engineers seeking low-noise performance, environmental resilience, and long-term stability in their sensing architecture.
Real-Time Sensing for Autonomous Platforms
Unlike piezoelectric sensors, which only detect high-frequency dynamic motion, SDI’s MEMS DC accelerometers provide accurate readings of both dynamic and static acceleration. This capability is essential for unmanned systems requiring continuous motion awareness, even when stationary.
A benefit of MEMS DC accelerometers is their ability to measure both static (DC) and dynamic (AC) acceleration, ensuring continuous, real-time monitoring. This makes them invaluable inertial navigation system applications, providing accurate acceleration data even in GPS-denied environments.
Built for Harsh Conditions and Long Missions
MEMS DC accelerometers from SDI are engineered for durability and stability. With minimal drift over time and low sensitivity to temperature changes, they are ideal for long-term deployment in unmanned systems that may be exposed to mechanical shocks, extreme temperatures, and long operational cycles.
Key advantages:
- Rugged MEMS construction survives vibration and impacts
- Low-impedance outputs ensure signal integrity
- Low noise, high-sensitivity detection improves system feedback and safety
- U.S.-based manufacturing, ensuring a stable supply chain and high-quality production standards
OEM-Friendly and Standards-Compliant
Designed with system integrators in mind, SDI’s accelerometers feature analog outputs for easy integration with flight controllers, onboard processors, and sensor fusion systems. Compliance with military standards, including MIL-STD-883 and MIL-PRF-38534, ensures they meet the rigorous demands of unmanned defense and aerospace applications.
In the world of unmanned systems, whether in the air, on the ground, or beneath the sea, precision motion sensing is vital. Applications like inertial navigation, autonomous stability control, and platform alignment depend on accelerometers that deliver real-time, reliable data, especially in GPS-denied or high-vibration environments.
