Compact 3D Ultrasonic Wind Sensors & Tactical Weather Stations for UAVs & GCS

Anemoment

TriSonica Mini UAV Wind SensorAnemoment LLC is the developer of the world’s smallest and lightest three-dimensional ultrasonic anemometer – the TriSonica™ Mini. Our compact, robust meteorological instruments deliver unmatched precision and accuracy for use in unmanned aerial vehicles (UAV, UAS, drones) and other unmanned platforms, and are ideal for a wide range of applications, including environmental monitoring, precision agriculture and wind profiling.

TriSonica™ Mini 3D Ultrasonic Anemometer

Compact 3D Wind Sensor for UAVs

Ultrasonic UAV AnemometerThe TriSonica™ Mini is the world’s smallest and lightest 3D ultrasonic anemometer. Small enough to fit in the palm of a hand, it weighs just 50 grams and has no moving parts, making it an ideal ultrasonic wind sensor for UAVs and other SWaP (size, weight and power)-conscious systems.

The compact, lightweight system uses acoustic wave pulses to sense wind movements in three dimensions (pitch, roll and yaw), providing high-accuracy real-time wind data for small drones and other mobile platforms.

Four open measurement paths of just 35mm – engineered to provide minimal distortion of the wind field – provide measurement redundancy as the path with the most distortion is removed from the calculations.

The TriSonica™ Mini provides wind speed, direction and temperature data outputs, as well as measurement of all three air flow dimensions. Accurate measurement is maintained even at tilt angles of up to 15 degrees, making the anemometer ideal for moving platforms such as UAVs and USVs (unmanned surface vessels), as well as fixed locations such as UAV ground control stations (GCS).

The TriSonica™ Mini anemometer outputs an ASCII string via RS-232 that can easily be stored to a text file. Data emulation allows the system to be directly connected to existing off-the-shelf data loggers without costly changes to associated electronics. Data output is factory set to user requirements and includes the emulation of many common types of wind sensors, allowing the TriSonica™ Mini to be used as a convenient upgrade to older, bulkier devices.

TriSonica™ Mini Weather Station

Compact Solid-State Weather Monitoring for UAV GCS

UAV GCS Weather Station

The TriSonica™ Mini is also available as a Tactical Weather Station variant. In addition to the wind data provided by the regular TriSonica™ Mini, the Tactical Weather Station also provides humidity, pressure, 3D accelerometer, magnetometer and compass data. This in turn allows calculation of accurate dew point, air density, yaw, pitch, and roll figures.

The TriSonica™ Mini Tactical Weather Station is designed to be incorporated into UAV ground control stations and other space-constrained positions where high-accuracy environmental data is required.

Ultrasonic Anemometer Applications

Precision Agriculture

Compact Wind Sensor for DroneUnmanned aircraft are commonly used for precision agriculture applications such as airborne fertilizer and pesticide spraying.

Environmental conditions can affect spray deposits and coverage, and the miniature TriSonica™ Mini anemometer is an ideal lightweight solution for gathering information on wind speed, direction and other factors that can help decision-making for precision agriculture operations.

Drone Mounted Wind SensorAtmospheric Monitoring

The TriSonica™ Mini anemometer can be attached to a fixed-wing or quadcopter UAV in order to capture boundary layer profiles and assess changes in atmospheric surface layer turbulence.

Naval Vessel Wind Profiling

Landing unmanned helicopters and other UAVs on naval vessels is a challenging task that requires precise real-time knowledge of the surrounding wind conditions. The TriSonica™ Mini ultrasonic anemometer is an ideal solution for capturing the data needed to support such operations.
