Abstract

An electronic device comprising: a sensor; a communication unit; and at least one processor configured to: receive a first speed measurement from the sensor; receive, via the communication unit, speed information transmitted by an external device; calculate at least one correction parameter based on the first speed measurement and the speed information; and adjust a second speed measurement that is received from the sensor based on the correction parameter.

Claims
