Abstract
A GPS (Global Positioning System) receiver and a navigation device and system utilizing the same includes a receiver which sequentially generates GPS data including current position information, based on signals received from GPS satellites. The GPS receiver further includes at least one filter which performs filtering with respect to the GPS data sequentially generated by the receiver and generates positioning data including the current position information, and a positioning data output device which selects a filter according to a selection signal and outputs the positioning data in accordance therewith.
Claims10
A GPS (Global Positioning System) receiver, comprising:
- a receiving means which sequentially generates GPS data including current position information, based on signals received from GPS satellites;
- a plurality of filtering means which perform filtering with respect to the GPS data sequentially generated by said receiving means and generate positioning data including the current position information;
- and
- a positioning data output means which selects any one of said plurality of filtering means according to a selection signal, and outputs the positioning data generated by the filtering means thus selected.
A GPS (Global Positioning System) receiver, comprising:
- a receiving means which sequentially generates GPS data including current position information, based on signals received from GPS satellites;
- a filtering means which performs filtering with respect to the GPS data sequentially generated by said receiving means according to a given condition, and generates positioning data including the current position information;
- and
- a positioning data output means which selects said given condition as one of a plurality of conditions being prepared according to a selection signal, provides said condition to said filtering means, and outputs the positioning data generated by said filtering means.
