Abstract
A method and system for determining a path taken by a vehicle are disclosed. A path portion is determined from a plurality of position estimates of the vehicle using a satellite positioning system. From the position estimates a determination is made that the path includes a poor satellite signal zone and the path portion is combined with a predetermined path portion corresponding to the poor satellite signal zone to provide the determined path.
Claims15
A method of determining a path taken by a vehicle, comprising:
- receiving satellite signals from a satellite positioning system;
- determining a path portion from a plurality of position estimates of the vehicle using a satellite positioning system;
- determining that the path includes a poor satellite signal zone;
- identifying a predetermined path portion corresponding to the poor satellite signal zone in a database comprising information for a plurality of poor satellite signal zones;
- retrieving the predetermined path portion from the database;
- providing the determined path by inserting the predetermined path portion corresponding to the poor satellite signal zone into the path portion;
- and
- calculating a distance travelled by the vehicle from the determined path.
A system for determining a path taken by a vehicle, comprising:
- a database comprising information for a plurality of poor satellite signal zones;
- a receiver for receiving satellite signals from a satellite positioning system;
- and
- one or more processors arranged to:
- determine a path portion from a plurality of position estimates of the vehicle using said satellite signals;
- determine that the path includes a poor satellite signal zone;
- identify a predetermined path portion corresponding to the poor satellite signal zone in the database;
- retrieve the predetermined path portion from the database;
- provide the determined path by inserting the predetermined path portion corresponding to the poor satellite signal zone into the path portion;
- and
- calculate a distance travelled by the vehicle from the determined path.
A vehicle configured to determine a path the vehicle has taken, comprising:
- a receiver for receiving satellite signals from a satellite positioning system;
- a database comprising information for a plurality of poor satellite signal zones;
- and
- one or more processors arranged to:
- determine a path portion from a plurality of position estimates of the vehicle using said satellite signals;
- determine that the path includes a poor satellite signal zone;
- identify a predetermined path portion corresponding to the poor satellite signal zone in the database;
- retrieve the predetermined path portion from the database;
- provide the determined path by inserting the predetermined path portion corresponding to the poor satellite signal zone into the path portion;
- and
- calculate a distance travelled by the vehicle from the determined path.
