Low-altitude altimeter and method |
摘要 |
A low-altitude altimeter (10) and a method of determining low altitudes for unmanned aerial vehicles (24). The altimeter includes at least two illuminators (12, 14), at least one sensor (16), and a computing device (18). The illuminators (12, 14) emit signals which are received by the sensor (16) in such a way that an angle at which they are received is determinable by the computing device (18). The computing device (18) processes each signal received by the sensor (16), determines the angle at which the sensor (16) received the signal, and, based thereon, determines the altitude of the unmanned aerial vehicle (24). When a first pair of illuminators are arranged along a fuselage axis, and a second pair of illuminators are arranged orthogonally to that axis, the computing device can combine first and second altitude, pitch angle, and roll angle measurements to provide a more refined altitude determination. |

1. An altimeter comprising:
at least two illuminators, with each illuminator operable to emit a signal; a downwardly orientable sensor operable to receive the signals emitted by the illuminators and sense data pertaining to angles from which the sensor received each of the signals; and a computing device in communication with the sensor and operable to determine the angle at which the sensor received each of the signals, and, based thereon, to determine an altitude. |
