Abstract: A positioning method includes: receiving a positioning signal at a receiver from a positioning satellite; determining an angle of arrival of the positioning signal relative to the receiver; applying a phase correction to the positioning signal, based on the angle of arrival, to produce a phase-corrected signal; and determining a location of the receiver using the phase-corrected signal.

Abstract: A method of triggering an action includes: determining that a mobile device is under water by: determining that an amplitude of a satellite positioning system (SPS) signal, or a wireless communication signal, or a combination thereof, received by the mobile device is below a threshold amplitude; or comparing data from a motion sensor of the mobile device with motion sensor data characteristic of entering water; or a combination thereof; determining that the mobile device has an action-inducing relationship to water; and taking the action in response to determining that the mobile device has the action-inducing relationship to water.
