Mechatronics (Electro-mechanical System Design)

Complex electro-mechanical and electro-opto-mechanical system design is an interdisciplinary problem involving electrical, optical, mechanical, control, and software engineering. SDL has teams of experts in all of these fields who have demonstrated the ability to develop working solutions which meet requirements.


  • System-level design
  • Sensor selection, modeling, and simulation
  • Actuator selection, modeling, and simulation
  • Custom printed circuit board design and fabrication
  • Structural design and fabrication
  • Embedded, real-time code
  • Disturbance rejection
  • Dynamic systems modeling (first principles, control systems, flexible body dynamics, ray tracing)
  • Design and analysis (MATLAB/SimuLink/Simscape/Simmechanics, ADAMS, NASTRAN)
  • Hardware-in-the-loop (HIL) testing and development
  • Model validation (system/parameter identification)
  • Closed-loop and feedforward control system performance validation testing



Space Based Infrared System

SBIRS High is a two-tier remote sensing satellite system working with other US defense systems to provide global below- and above-the-horizon detection as well as tracking and discrimination of missiles in their boost, post-boost, midcourse and reentry phases of flight.


Dynamic Ionosphere Cubesat Experiment

Twin CubeSats mapped the geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere.


Tropospheric Emission Spectrometer-Focal Plane Opto-Mechanical Assembly

SDL designed, fabricated, and tested the re-imaging optics and focal plane mechanical support/cryogenic isolation FPOMA for TES, a high-resolution infrared imaging Fourier transform spectrometer.


Cyrogenic Latching Instrument Connector

CLIC is a remotely-operated device that provides active, inexpensive thermal switch capabilities when combined with SDL’s thermal links. It does not require power when latched and is suitable for cryogenic environments.
