Problems solved by technology

However, the compass 72 of the GPS navigation device 9 cannot display the correct direction when the car body is stationary or running at a low speed. This is because the satellite positioning system 8 itself is constantly moving relative to the car body running at a low speed, causing its There is an error in the angle conversion of the transmitted positioning signal 801, but currently the data received for this kind of low-speed driving is mostly ignored or not used, so when the car body is running at a low speed, the compass 72 will jump or be inaccurate phenomenon, resulting in the inability to provide correct angle data

Abstract

The present invention relates to an angle mutual correction method of navigation equipment. The navigation equipment is mounted on a moving body, and has a sallelite location module and an electronic compass. The salletite location module is used for receiving a location signal, and converting it into a GPS location data. The angle mutual correction method of the navigation equipment includes the following steps: (A), detecting that moving speed of moving body is not higher than a preset value or not, if it is not higher than said preset value, making step (B), using an angle value measured by electronic compass to correct an angle value in GPS location data; and (C), outputting the corrected GPS location data.

Description

【Technical field】 [0001] The present invention relates to a correction method for a navigation device, in particular to a correction method for a navigation device that can obtain accurate angle data at any moving speed in conjunction with the Global Positioning System (GPS) positioning technology and its device. 【Background technique】 [0002] The global satellite positioning system (hereinafter referred to as GPS) is a combination of satellite system and radio wave technology, which can provide users with precise positioning, moving speed and time. The positioning principle is mainly to use a GPS navigation device to receive satellite system signals to determine the user The location and altitude are continuously transmitted by the satellite system in the sky to the GPS navigation device, and the GPS navigation device is also continuously receiving the latest data from the satellite system. [0003] Such as figure 1 As shown, the current GPS navigation device 9 mainly ha...
