Description of the invention: [Technical field of the invention] The present invention is a power saving method applied to a satellite navigation device, such as a personal digital assistant. A satellite navigation device for navigating, in particular, a power saving method for causing a satellite navigation device to perform a normal mode or a power saving mode according to a displacement state. [Prior Art] ❿ In general, to be in a personal digital assistant ((Personal Digital sslstant In the provision of satellite positioning services in PM), it is necessary to install a global satellite system to carry out the necessary signal injection, Wei and processing to obtain the current position coordinates and to navigate; η. Global satellite positioning The system (G1〇bai System; GPS) was built by the US government and initially provided only military direct = open to commercialization. The US Global Satellite (four) system is composed of three ^^ The composition of the 'partial part is space' is operated by twenty-four positioning satellites in six, the satellite is at a height of 20,000 kilometers, and twelve hours around the earth = one degree to ensure that each The satellites can be used at the same time and time to form the virtual azimuth coordinates in space. 1290229 Please refer to the third figure, which is the control flow chart of the power saving mode of the present invention, and the following steps are included. Start to expand, when the position parameter is less than the threshold value, the displacement state of the S3i. star navigation device is the stop state SS2; then the control panel group enables the satellite navigation device to execute the dependency S33 according to the stop I state; finally, the whole process is ended. The satellite (4) system is 3 seconds, which means that the global positioning system module receives 20 pieces of position data per minute. It is assumed that the door root value of 2 3 % is set to 1 minute for 1 minute. As shown in the fourth figure. , is a flow chart of the invention-only return to the power-saving mode, at least includes the following steps: starting from the beginning 'although the user temporarily parked on the roadside, and the satellite navigation device is in the normal mode; S曰4b this satellite The silk can be called the personal assistant; the movement of the touched car is more than 3 meters S42'. This step is judged by the control module according to the i-point position parameter, and the position parameter is based on the position data. ==Quantity, last-Pen position 2=Set normal mode S43. Wl· version is the transfer wire S and the charm guide continues to execute =3 ', then the stop state is determined and the satellite navigation device enters the succession at least one end of the whole process Lighting module and sound module; finally,
