1. Advantages of vehicle temperature tracker

1. Global positioning. The large number and uniform distribution of vehicle temperature tracker satellites ensure that at least 4 vehicle temperature tracker satellites can be observed simultaneously anywhere on Earth at any time. To ensure the realization of global all-weather continuous navigation and positioning services (except thunder and lightning should not be observed).

2, high positioning accuracy. The relative positioning accuracy of the vehicle temperature tracker can reach 10-6m within 50km, 10-7m within 100-500km, and 10-9m within 1000km. In 300-1500m engineering precision positioning, the plane position error of the solution is less than 1mm when observed for more than 1 hour. Compared with the side length measured by the ME-5000 electromagnetic wave rangefinder, the side length difference is up to 0.5mm, and the calibration error is 0.3mm.

3. Short observation time. With the continuous improvement of the vehicle temperature tracker system, relatively static positioning within 20km takes only 15-20 minutes; When the distance between each mobile station and the reference station is less than 15KM, the observation time of the mobile station is only 1-2 minutes. When real-time dynamic positioning mode is adopted, each station observation takes only a few seconds.

4, no need to see between the stations. vehicle temperature tracker survey requires only open space and does not require the stations to be visible to each other, so it is no longer necessary to build a tower.

5, the instrument is easy to operate. With the continuous improvement of vehicle temperature tracker receiver, the degree of automation of vehicle temperature tracker measurement is getting higher and higher, and some of them have tended to be "silly".

6, can provide global unified three-dimensional geocentric coordinates. vehicle temperature tracker level can meet the fourth level accuracy, in addition, vehicle temperature tracker positioning is calculated in the global unified WGS-84 coordinate system, so the measurement results of different locations around the world are interrelated.

7. Strong adaptability. The vehicle temperature tracker is more adaptable and requires very little of the environment. Such as deserts, mountain tops, isolated islands and so on.

2. Disadvantages of using vehicle temperature tracker

1. vehicle temperature tracker cannot be 100% positioned, and indoor positioning is even less accurate. vehicle temperature tracker will also be affected by many aspects, including buildings, viaducts, radio waves, etc. Generally speaking, the more empty the vehicle temperature tracker is, the more accurate the positioning.

2. Affected by the state of satellites in the sky. Do not use the vehicle temperature tracker once or twice or one or two days to determine the quality of the vehicle temperature tracker, because the sky satellite status is different every day, maybe the same place, the signal is full in the morning, but it can not be located at night. You can't even locate it for days on end.

3, can not be located indoors. Since the vehicle temperature tracker receives the signal directly from the satellite, it cannot be used indoors. But basically indoor positioning is meaningless, at least I can't navigate at home.

4, the vehicle temperature tracker instrument is different, the effect may be very different.
