AIMMS
Aircraft-Integrated Meteorological Measurement System

The AIMMS - 20 delivers precise real-time meteorological data at rates up to 20Hz. Formed by a combination of four modules: an Inertial Measurement Unit module (IMU) that delivers six degree-of-freedom rate data at 40Hz; a GPS Phase Module that processes satellite navigation signals from two antennas; an Air-Data-Probe (ADP) that measures temperature, humidity, barometric pressure and the aircraft-relative flow vector; and, a Central Processing Module (CPM) to process GPS data, inertial signals and air-data information that yield accurate wind data when combined.
