GPS navigation apparatus
First Claim
1. A GPS navigation apparatus comprising:
- a GPS signals receiver for acquiring positional data;
a memory for storing positional data comprising a locus of tracking points including a start point, a destination point, and a plurality of intermediary locations points;
a registrar for storing and recalling a selected one of a loci of tracking points;
a route conversion selector for selecting a conversion type from among a plurality of conversion types, for converting said selected locus of tracking points into a new return route, and wherein each new return route is dependent upon the conversion type;
a position data extractor for automatically extracting those data from the selected locus of tracking points designated by the selected type of conversion and creating the new return route based on said automatic data extraction; and
a display for graphically illustrating the new return route as a start point, a destination point, and new route data derived from said automatic data extraction.

Abstract
In a GPS navigation apparatus, a procedure of preparation of route for navigation using a specific point (WAY-POINT or MARK-POINT) established and registered by the tracking function is simplified. A TRACK list picture is read out from a MENU picture by the predetermined operation, and a desired TRACK name is designated from the list. When a type the specific point is selected by the predetermined operation to designate conversion from the TRACK to a ROUTE, position data of the START POINT, the specific point of the selected type, and the DESTINATION POINT, of the designated TRACK name are extracted, and interpolation data connecting the positions by straight line in the time series sequence is produced to construct a ROUTE for navigation. Conventionally, the selection has been made by each POINT unit, however, an automatic conversion in a batch in a TRACK unit is employed, and thus a route creating operation is extremely simplified.
