Abstract (en)
[origin: WO2019220040A1] The invention is based on the observation that, considering the pedalling movement, the power developed by a cyclist takes the form of a permanent sine curve with a frequency that is double the pedalling frequency. This cyclic power variation results in a small oscillation of the speed of the cyclist, the amplitude of which can be observed through GNSS phase measurements which are more precise by an order of magnitude. A first aspect of the invention relates to a method for determining the pedalling cadence of a cyclist (10) on a cycle (12), wherein the pedalling cadence is extracted from an oscillation of GNSS signal phase measurements (16) taken on the cycle (12) via a GNSS receiver (14) or an oscillation of measurements calculated on the basis of the phase measurements.
