Summary
The AIMMS (Aircraft Integrated Meteorological Measurement System) is a fully-integrated instrumentation system providing high-accuracy measurements of temperature, telative humidity, three-dimensional winds and turbulence. The embedded GPS / Inertial subsystem also provides measurement of inertial accelerations (X, Y, Z), inertial angular rates (P, Q, R), GPS time, position and velocity as well as attitude (roll, pitch, yaw).
