Brief description of the drawings
Fig. 1 is a kind of GPS positioning system figure of the invention.
Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
Embodiment one
As shown in figure 1, a kind of GPS positioning system, including
Acquisition module, for obtaining the multigroup gps coordinate in Preset Time.
Specifically, GPS module is per second to transmit a gps coordinate to MCU.In actual applications, with every ten seconds (ten groups altogether
Gps coordinate) it is a Preset Time, it is per second to be input into one group of gps coordinate to MCU, continuous ten groups are continuously input into MCU altogether
Gps coordinate.
Every group of gps coordinate is included：Time, longitude, latitude, speed, height, direction and number of satellite.
Computing module, for calculating that mobile device moves in Preset Time in L1 and multigroup gps coordinate
Benchmark gps coordinate.
Specifically, being apart from the computing formula that L1 is used：
L1=V*T；
Wherein：V is ten average speeds of speed that ten groups of gps coordinates in ten seconds include, T be Preset Time (
It it is exactly ten seconds).
The determination of the benchmark gps coordinate in ten groups of gps coordinates passes through respectively by ten longitudes and ten in ten groups of gps coordinates
Individual latitude carries out bubble sort respectively, and benchmark gps coordinate is constituted by a longitude and a latitude in an intermediate position.
Comparison module, for calculating benchmark gps coordinate successively and last group of gps coordinate in multigroup gps coordinate to first
The distance between group gps coordinate, will at first calculate the corresponding gps coordinate of distance less than L1/2 as effective gps coordinate, if
Multigroup gps coordinate is all higher than being equal to L1/2 with the distance of benchmark gps coordinate, then using benchmark gps coordinate as effective gps coordinate.
Specifically, the distance between last group of gps coordinate first in calculating benchmark gps coordinate and ten groups of gps coordinates
L2, compares L2 and L1/2, if L2 is more than or equal to L1/2 between calculating benchmark gps coordinate and second from the bottom group of gps coordinate
Apart from L2；The like, until the benchmark gps coordinate for calculating is small with the distance between ten groups of the one of gps coordinate group of gps coordinates
Untill L1/2, using this group of gps coordinate as effective gps coordinate；If in the benchmark gps coordinate for calculating and ten groups of gps coordinates
The distance between all of gps coordinate be all higher than being equal to L1/2, then using benchmark gps coordinate as effective gps coordinate.
Assume that it is to judge to calculate to the 3rd group of gps coordinate (namely third from the bottom group of gps coordinate) in the present embodiment
L2 is less than L1/2, then using third from the bottom group of gps coordinate as effective gps coordinate.
In an alternative embodiment, the distance between calculating benchmark gps coordinate and ten groups of gps coordinates L2 successively；
Come to ten L2, each L2 is not less than L1/2, therefore using benchmark gps coordinate as effective gps coordinate.
It is determined that mobile device accurate location and motion track when, can using by said system draw it is effective
Gps coordinate.
