The speed of service, and the path of navigation judges the position that next second guider carrier will be reached；
C, CPU element calculate the movement from current time to next second guider carrier with reference to the path of navigation
Line segment, and the moving process by guider carrier on the movement line segment splits into several continuous fragments, this several
Corresponding fragment can constitute continuous navigation picture, then by the touch-screen of guider manipulate unit in 1 second once and
Latency period shows the navigation picture of each fragment.
In said process B, if the gps receiver of guider can not normally receive gps signal, guider
CPU element judges next second according only to translational speed information and the path of navigation from guider anticipation carrier
The position that guider carrier will be reached.
In above-mentioned technical proposal, the mobile line segment include the straightway corresponding with linear pattern section and with section of turning round
Corresponding curvilinear lengths.
The device have the advantages that：1st, the method for the display navigation picture of guider of the invention, will be shown
Guider carrier moving process by being updated once every second, be changed into per second and update multiple, make display along path of navigation row
The process entered is more continuous, the defect that the vision of navigation picture during real-time navigation is paused or jumped is eliminated, while can be accurate
In real time the position of location navigation image, has carried out precision navigation.2nd, in the present invention, neighbouring high building or massif etc. are received in gps signal
During the high influence of topography, guider can with according to before carrier move speed, the speed of service of predictive vector future time period,
According to the velocity information and path of navigation, the location and time that guider carrier will be reached is judged, it is ensured that normal navigation, also
Ensure that precision.3rd, in the present invention, CPU element is calculated from current time with reference to path of navigation and carried to next second guider
The mobile line segment of body is practical including the straightway and with turn round section corresponding curvilinear lengths corresponding with linear section
Property is strong, it is adaptable to complicated highway section.
