Abstract
Identifying and estimating values of atmospheric conditions for use in estimating an altitude of a mobile device. Systems and methods for monitoring one or more conditions before estimating an altitude of a mobile device may receive a reference pressure that was determined using a measurement of pressure measured by a reference pressure sensor, and determine if a temperature condition is detected. After determining that the temperature condition is not detected, the systems and methods may compute a first estimate of an altitude of a mobile device using the reference pressure. After determining that the temperature condition is detected, the systems and methods may compute an estimate of a pressure at the location of the reference pressure sensor using the reference pressure, a first measurement of temperature that was used to compute the reference pressure, an estimated altitude of the location of the reference pressure sensor, and the reference altitude, and then compute a second estimate of the altitude of the mobile device using the estimate of pressure and a second measurement of temperature that was measured at another location that is different from the location of the refer…
