To combine Fig. 3 and Fig. 4 to introduce the method for application of this locating device below.

Fig. 3 shows the synoptic diagram that obtains motion path according to the use locating device of one embodiment of the present invention.In Fig. 3, in order to obtain an absolute motion path of locating device, locating device receives a gps signal from gps signal source 301 at the initial position P1 with gps signal earlier, obtains the absolute coordinates P1A (N39 °, E115 °) of position P1.This gps signal source can be the various sources that can launch gps signal such as satellite or base station.Simultaneously, locating device is gathered the primary data information (pdi) of this position, and to this set positions relative coordinate P1 (0,0).Then, locating device enters into the zone that does not have gps signal in company with moving object, and according to instruction, at a plurality of position P2, P3, P4 gather the primary data information (pdi) of this position respectively, calculate the relative coordinate of each position.These relative coordinates can all be based on the relative coordinate of initial position P1, also can be based on the relative coordinate of a record position.After the relative coordinate that obtains each position, a complete relative motion path has just obtained.And in order to obtain the absolute motion path, only need add on the basis of the relative coordinate of each position and can obtain the absolute coordinates P1A of initial position P1 the absolute coordinates of each position, thereby obtain complete absolute motion path.

Preferably, the next one that initial position is adjacent does not have the distance between the collection position of gps signal should be as much as possible little, to reduce initial relative error.Preferably with near the position that gps signal is arranged at the edge in no gps signal zone as initial position, shortening the distance in the zone of gps signal is arranged between the adjacent positioned position, thus the as far as possible little error of introducing.

Preferably, if the tester does not manually begin not have the gps signal location in certain position control, locating device can start raw data acquisition unit image data automatically immediately and position when entering does not have the gps signal place.

Certainly, also can be in motion process one or several have the position of gps signal to obtain the absolute coordinates of this or several positions, thereby combine each position relative coordinate and obtain the absolute coordinates of each position.

If be merely acquisition relative motion path, then need not to accept gps signal.Only can calculate the relative coordinate of each position through the data of raw data acquisition unit collection.Certainly, the gps signal receiving element also just can save.

Fig. 4 shows the synoptic diagram according to the use locating device correction of movement path of one embodiment of the present invention.In order to improve bearing accuracy; If the user can be known one or the relative coordinate accurately of several positions in the motion path through other means; For example use ruler, laser, drawing etc., the relative coordinate of position P3 is modified to P3' (9 ,-1) through manual input; Other each position P2 then, the relative coordinate of P4 just can be proofreaied and correct through the difference that on the basis of former relative coordinate, adds P3' and P3.Certainly, the position that obtains accurate coordinate is many more, and the value that is corrected is also just accurate more.If what be corrected all is relative coordinate, then initial position also can be used as one and has the reference position of accurate relative coordinate and need not to be corrected, because the relative coordinate of other positions all is based on the relative coordinate of this initial position and is fixed.And if what be corrected is absolute coordinates, and the absolute coordinates of initial position do not obtain through gps signal, and promptly initial position can not be as a reference position in absolute coordinate system, thereby it also need be corrected.

If the user can be known one or the absolute coordinates accurately of several positions in the motion path through other means, then for the relative motion path that only obtains, thereby the absolute coordinates that can obtain each position as stated above obtains the absolute motion path; And for the situation that obtains the absolute motion path; Through or the absolute coordinates of several positions that the user is manually imported; And so as to the absolute coordinates that pass through the gps signal acquisition that obtains the absolute motion path together as benchmark, just can proofread and correct the absolute coordinates of other positions.Based on the algorithm that the absolute coordinates of a plurality of positions is proofreaied and correct motion path, can use the error correction algorithms of various known mathematics.

One of the manual input of user or the accurate coordinate of several positions can be imported through the load module that is positioned on the processing terminal, also can this load module confession user input at any time in the process of motion be set on the locating device.This accurately coordinate through the processing terminal computing other position coordinateses are proofreaied and correct.

Above-mentioned processing terminal can be various general-purpose computations terminals with handled function, like computing machine, also possibly be the various data processing equipments with the supporting customization of this locating device.

Should be appreciated that the method for application of above-described locating device and various locating devices may be used to have fully the zone of gps signal, or the faint zone of gps signal.Above-mentioned locating device and method of application are particularly useful for that inlet chamber is interior, underground, the tunnel, wait environment under water; Be particularly useful in above environment, carrying out the certain physical parameters collection; Like network signal, air quality, radiation dose, chemical constitution etc., thereby obtain areal distribution information.Through this locating device and method of application thereof, make under the environment of no gps signal to obtain locating information and become possibility, also need active data harvester and method be provided in the industry that particular surroundings is located Information Monitoring for various.
