## Product Overview Using commercial aircraft can be expensive , using remotely piloted aircraft systems to gather local weather conditions aloft can tremendously cost e ffective , effic ient, and safe . The ability to accurately define and forecast such local conditions depends on the quality of available upper

- air data. Because of this, local weather measurements are required to determine weather forcasts. The ARIM320 is a weather

- sensing solution for measuring mission

- critical data, which is able to deliver that data to ground personnel using satellite telemetry. Accurate wind measurement from an airborne platform poses a challenging problem given the fact that the aircraft is moving many times faster than the wind being measured. As a result, the wind signal of interest is only a small portion of the measu red air

- motion data and is dominated by the motion of the aircraft itself. Under these circumstances, precision wind measurement to an accuracy better than 0.5 m/s (1 knot) requires acquisition of the true airspeed to better than 0.7 knots accuracy, flow direction (sideslip) to better than 0.1 degree accuracy and true heading to better than 0.2 degree accuracy. The ARIM320 system delivers this level of performance in a small, integrated, light

- weight package that is easy to calibrate with the pressure boom molded d irectly into the airframe and the electronics safely sealed within the electronics bay. The TD100E & M M icroclimatology M ission C onfiguration uses Brican’s high performance composite aircraft platform fit ted with an electric motor and LiPo batteries for extended duration flight of approximately 4 hours in the air. The TD100 aircraft carries a modified version of Aventech’s ARIM320 Digital Air Probe sensor suite. The cli matology payload package provides the user with the ability to review and react to sam pled data in real

- time via an online interface (in the form of a Ground Station readout). This will allow the Ground Station Operator to interact with the aircraft in

- situ and add additional waypoints based on real

- time data feedback and therefore re

- task or extend the scope of the mission or survey area while the aircraft is still in flight.

Payload Description The ARIM320 is an air data measurement system capable of providing:

- Static Pressure (Ps)

- Total Pressure (Pt)

- Indicated Air Speed (IAS) / Altitude (IA)

- Calibrated Air Speed (CAS) / Altitude (CA)

- True Air Speed (TAS) / Altitude (TA)

- Equivalent Air Speed (EAS) / Altitude (EA)

- Angle of Attack (AOA)

- Angle of Sideslip (AOS)

- Total Air Temperature (TAT)

- Outside Air Temperatur e (OAT)

- And Impact Pressure The ARIM320 evaluates the parameters listed above from a base set of aerodynamic, meteorological, GPS code and carrier

- phase, and inertial measurements which include:

- Pitot Pressure

- Static Pressure

- AOA Differential Pressure

- AOS Differential Pressure

- Temperature

- Humidity

- GPS Time - GPS Position (Latitude, Longitude, and Altitude)

- GPS Velocity

- Three

- axis Accelerations (X, Y, Z)

- Three

- axis Rates (Roll, Pitch, Yaw) Combining the GPS carrier

- phase information with the acceleration and rate information using Aventech’s proprietary Extende d Kalman Filter (EKF) algorithm subsequently provides:

- Airframe Attitude (Roll, Pitch, Yaw)

- True Heading (TH)

- Course Heading (CH)

- Three

- Dimensional Winds. Integrated inertial ly - aided GPS attitude system provide s :

- Aircraft Attitude (Roll, Pitch, and Yaw)

- Inertial Velocity

- Wind Speed and Wind Direction

- Rate of Climb (ROC)

- Flight Path Angle (FPA) The air

- data, GPS, inertial sensors and all analog and digital processing electronics are all fully integrated into a single miniature Air Data Probe enclosure which is mounted within the fuselage of the airframe. The probe only requires power in, and provides all acquired air data measurements via a digital communications interface.
