  G500M-Mini GPS Tracker

  To get the position of the receiver, when the receiver clock clock and the GPS standard are strictly synchronized, the location is to be solved. The position is 3 unknown variables, and 3 independent equations are required to solve. However, in the actual situation, it is difficult to be strictly synchronized when the receiver clock clock and the GPS standard are strictly synchronized. In this way, we take the receiving machine time and GPS standard time deviation as an unknown variable. In this way, it takes 4 independent equations to solve. 4 observation satellites. Figure 1 GPS positioning schematic diagram (not considered the time deviation) assume that the receiver position is (xu, yu, zu), and the time deviation of the receiver is TU, the distance deviation caused by the time deviation is the pseudo -distance observation value obtained. We can get the connected equation (5) to the upper -style linear, that is, in the real position (xu, yu, zu), the Taylor level is expanded, ignoring the high number of items, and the formula (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual actual (6) is the actual reality. The computing formula of the overlapping formula is the change in the real position (xu, yu, zu) less than a certain threshold. Finally, it can be obtained as a basis for adjusting the time deviation of the receiving machine. The calculation is generally used by matrix. To solve this equation, we also need to know the positions of 4 satellites (XJ, YJ, ZJ) in advance, and the satellite position can be obtained from the star calendar of the satellite. GPS Satellite Star Calendar gives this star's star calendar, which can calculate the real -time position of the satellite according to the Star calendar, and the star calendar gives out the parameters of eliminating satellite star clock errors, relativity errors, self -rotation errors, ionization layers and stream layer errors. The position calculated based on these parameters can basically eliminate the above errors. The basic steps to solve the position of the satellite position are: calculate the average angle speed of the satellite operation ① Calculate the naturalization time; ② Calculate the flat point angle of the observation time; ⑥ Calculate the horn point distance; ⑦ Calculate the righteous item of the swimming; ⑧ Calculate the closing the correction of the promotion distance angle, satellite diameter, and track inclination; The position. It is particularly worth pointing out that when calculating the near -point corner VK of the satellite, formula (7) should be used, E as the eccentricity rate, and EK is the satellite closer to the point angle. Some reference books to calculate the formula of the true near -point angle of the satellite will cause the problem of the quirky issue of the near -point angle of the satellite, so that the satellite is correct. After the above calculations are performed, further eliminate various errors according to the error parameters of the broadcast in the star calendar. In this way, we get a complete process of using the GPS Star calendar for navigation positioning and solution.
