Some defects in the area measurement
The Mu meter is an instrument for measuring the land area. The instrument has a perfect combination of high-precision GPS positioning system, accurate area calculation method and intelligent handheld computer system, realizing any irregular area of ​​real-time testing and dynamic graphics. Display and data intelligence processing and storage. It is a fully functional, highly-accurate instrument. When displaying the results, the Mu meter can be displayed in two units at the same time, that is, square meters and acres. The meter can measure multiple parameters at the same time: area, distance, perimeter, longitude, latitude, altitude, time, unit price, and total price.

The Mu device produced by Top Instruments contains GPS global positioning function. It can receive signals through satellites and measure the land area. However, there are still some flaws in its operation. 1. The key to the precise positioning of the GPS system is the precise calculation of the distance between the satellite and the receiver, ie according to the formula Distance = Speed* Time. However, in large cities or mountainous areas, due to the influence of high-rise buildings and trees on the signal, it also leads to non-linear propagation of signals, and there is a certain error in the calculation. 2. The difference in the position of the selected control point in the GPS measurement will affect the accuracy of the observation point. When the instrument interferes in receiving signals, the point coordinates may produce a certain error. 3. There is a difference between GPS measurement results and conventional measurement results in different models of GPS measurement results, and sometimes there is a large difference.
