The invention is suitable for navigation field, and provides a method for displaying navigation images at crossroad, and a device and a GPS navigation apparatus thereof. The method comprises the following steps of: calculating the estimated time of arrival from a current position of a navigation object to a crossroad; determining whether the estimated time of arrival is in a response time range, and if the estimated time of arrival is in the range, sending a command to enlarge the navigation image at the crossroad; generating the correspondingly enlarged navigation image at the crossroad; anddisplaying the enlarged navigation image at the crossroad. The invention can display the crossroad image and vehicle travelling track with dynamic enlargement with voice guide, so as to remarkably facilitate the service.
Description
technical field [0001] The invention belongs to the field of navigation, and in particular relates to a display method and device for an intersection navigation picture and a GPS navigation device. Background technique [0002] The Global Positioning System (GPS) uses navigation satellites for timing, positioning and ranging, and can provide all-weather, all-round and continuous real-time high-precision three-dimensional space and speed for users at sea, land and air all over the world. and time information. The system is mainly composed of three parts, namely the space part, the ground control part and the user device part. The space part is composed of 24 satellites, which are distributed in 6 track planes. The ground control part is composed of the main control station responsible for managing and coordinating the work of the entire ground control system, the ground antenna that injects the search message into the satellite under the control of the main control station,...
