SYSTEM AND METHOD FOR THREE DIMENSION LOCATION DETERMINATION
摘要
The location of an asset can be determined in three dimensions using pressure data from reference sensors in combination with conventional two-dimensional location technology, such as GPA or TDOA. In a building, reference sensors are distributed on multiple floors and transmit accurate pressure readings to a receiver. The asset also has a pressure sensing element and transmits the pressure at its location to the receiver. The asset pressure value is compared with the reference pressure sensor values to determine the floor in a building on which the asset is located. Thus, the combination of accurate two-dimensional location technology and pressure sensors can accurately determine the location of an asset in three dimensions.
