In order to enable a geopositioning receiver of a user to resolve phase ambiguities without necessarily using multi-frequency observations, assistance data is developed thanks to measurements made at a reference network (10, 12, 14) and sent to the receiver of the user. The assistance data used preferably consist of transmitter clock values associated with the carrier code sliding combination (Θeme) or with data sufficient for reconstructing said values. The transmitter clock values associated with the carrier code sliding combination (Θeme) can be reconstructed from iono-free transmitter clock values (heme) and clock biases (C′eme), for example. |
