Abstract:
1. An integrated positioning apparatus for use in a carrier, comprising: a processing module, arranged for executing a navigation program, and for generating a control signal while a preset condition is met; a satellite positioning module, arranged for providing satellite positioning information; an inertial positioning module, including an inertial detection module for detecting a position vector and a rotation angle, and a magnetic detection apparatus being an electronic compass for providing direction information, wherein the electronic compass of the inertial positioning module generates inertial positioning information based on the position vector, the rotation angle, and the direction information; a transmission interface, connected to the processing module; and a switching module, arranged between the transmission interface and the satellite positioning module, and between the transmission interface and the inertial positioning module, wherein the switching module is selectively switched to a first status or a second status based on the control signal received from the processing module, and the switching module is switched to exclusively connect the transmission interface to the satellite positioning module for transmitting the satellite positioning information to the processing module for use by the navigation program while the switching module is in the first status, and the switching module is switched to exclusively connect the transmission interface to the inertial positioning module for transmitting the inertial positioning information to the processing module for use by the navigation program while the switching module is in the second status, such that the navigation program respectively uses either the satellite positioning information or the inertial positioning information for navigation; wherein the preset condition is determined according to a condition that a resolution of a navigation map used by the navigation program is enhanced over a preset value.
