The invention discloses a positioning system based on a gyroscope, a GPS and a three-axis magnetic sensor. The positioning system comprises the gyroscope, the GPS, the three-axis magnetic sensor, a collection circuit, a microcontroller, a storage, a wireless communication module, a display terminal and a power module. The invention further discloses a positioning method based on the gyroscope, the GPS and the three-axis magnetic sensor. According to the positioning method, output data of the GPS, the gyroscope and the three-axis magnetic sensor are synchronously collected, and integrated positioning data are calculated through the output data of the gyroscope and the three-axis magnetic sensor; when the GPS outputs GPS positioning data, the GPS positioning data are displayed through the display terminal; when the GPS does not output the GPS positioning data, the integrated positioning data are displayed through the display terminal, and the problems that a GPS of an existing vehicle-mounted mobile terminal is easily disturbed, signals are easily interrupted, and positioning cannot be accurate are effectively solved.
Description
technical field [0001] The invention relates to positioning technology, in particular to a positioning system and method based on gyroscopes, GPS and three-axis magnetic sensors. Background technique [0002] The current mobile terminal positioning systems such as vehicles mainly use GPS. GPS receives satellite signals, extracts original measurement and demodulates the data to obtain current position information, and displays the position on the display terminal in combination with electronic maps, but GPS is easily interfered. , such as under viaducts, large buildings, semi-open spaces and indoors, the signal is easily interrupted and cannot be located, causing great application problems. Contents of the invention [0003] The invention provides a positioning system and method based on a gyroscope, a GPS and a three-axis magnetic sensor, and solves the problems that the GPS of an existing mobile terminal such as a vehicle is easily interfered, the signal is easily interru...
