Abstract

Wind parameter indication device and method for providing an indication of wind speed and wind direction. The device is deployed along an aerial trajectory toward a ground surface, such as after being ejected from an aircraft in flight. The device includes an anemometer, an altimeter, a compass, a processor and a transmitter. The anemometer obtains local wind speed and local wind direction measurements along the trajectory. The altimeter obtains altitude measurements along the trajectory. The compass obtains direction measurements along the trajectory. The device may further include an accelerometer, for obtaining acceleration measurements along the trajectory. The processor determines a wind speed value and a wind direction value associated with a predetermined altitude of the device. The transmitter transmits the determined wind speed value and wind direction value to a remotely located receiver. The device may further include a stabilizing decelerator to stabilize and decelerate the device along the trajectory.

Dependent claims

A wind parameter indication device for providing wind speed and wind direction to a remotely located receiver, wherein said device is ejected in midair to fall along an aerial trajectory from a landing approach height until a ground surface, characterized in that said device operates independently of external data sources, said device comprising:

a compass, operative to continuously obtain direction measurements along said trajectory;
an anemometer, operative to continuously obtain local wind speed and local wind direction measurements along said trajectory using the direction measurements obtained by said compass;
an altimeter, operative to continuously obtain altitude measurements along said trajectory;
a processor, coupled with said anemometer, with said altimeter, and with said compass, said processor operative to determine the altitude measurement corresponding to at least one predetermined altitude of said device relative to said ground surface, after said device has reached said ground surface, and to then determine a wind speed value and a wind direction value associated with said at least one predetermined altitude based on the obtained measurements;
and
a transmitter, coupled with said processor, said transmitter operative to transmit said wind speed value and said wind direction value associated with said at least one predetermined altitude to said remotely located receiver.
