Smart sensor modules are combined using a Controller Area Network (CAN) to form the Aircraft-Integrated Meteorological Measurement System, or AIMMS-20, which delivers precise real-time meteorological data at rates up to 20Hz (temperature, humidity, wind). A minimum of four modules are combined to form an AIMMS-20 system: 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.


  • Provides real-time measurement of the 3-dimensional wind vector with excellent frequency response
  • Provides temperature, humidity and pressure data
  • Includes output of high-precision aircraft attitude data (bank angle, pitch angle and true heading)
  • A fully integrated package with all components necessary for stand-alone operation to minimize the cost and complexities pertaining to installation and FAA certification
  • Full support for aerodynamic calibration to minimize the time and effort necessary to analyze flight-calibration data
  • Unrivalled price-performance ratio for airborne meteorological observation
  • Can be integrated with a host data system, or operated independently using internal FLASH memory to store information for post-flight transfer
  • Rugged construction with hermetically sealed sensor electronics for in-service reliability


  • Aerial application of pesticides
    • Wind data critical for monitoring off-target drift potential
    • Spray optimization (flight line offsets taking wind drift into account to improve spray targeting)
  • Weather observation in support of wild land fire operations
    • Fire weather forecasting
    • Prescribed burn management
    • Fire aviation support
  • Atmospheric observation for scientific research
