What are the errors of the single point solution, floating point solution, and fixed solution in the

The single-point solution is that the mobile station and the base station cannot be connected with each other when the RTK is working, and only the mobile station is working, and there is generally no data display.

The accuracy of the floating-point solution is relatively high, sometimes barely within 10cm, and this accuracy can also be used if you are measuring fish ponds or mountains.

The fixed solution is the most accurate data, with an accuracy of 3-5cm, which can basically be used as a root point or directly used for lofting.

It's actually confidence.

Generally speaking, the fixed solution is the best, the floating-point solution is secondary, and the single-point solution has not been convergent calculated, so it cannot be used as a basis, the single-point solution is generally meter-level (generally more than one meter) error, the floating-point solution is tens of centimeters (the accuracy will be higher and higher with time, and the accuracy is getting better and better), and the fixed solution is generally one or two centimeters.

The single-point solution is generally meter-level (generally more than one meter) error, the floating-point solution is tens of centimeters (the accuracy will get higher and higher with time, and the accuracy will get better and better), and the fixed solution is generally one or two centimeters.

This can't be said to be how much the error is, this is actually a matter of confidence, you mainly observe the beating of the data, generally speaking, the high confidence level is sure that the data is not cheap, so the fixed solution is the best, the floating point solution is second, the difference decomposition is the last, and the single-point solution She has not carried out convergence calculations, so he can not be used as a basis, and what is the error, generally look at her h and v, if you think it is appropriate, give a yo.

The single-point solution is that the mobile station and the base station cannot be connected with each other when the RTK is working, and only the mobile station is working, and there is generally no data display.

Floating-point solution: It is a relatively high accuracy, sometimes barely within 10cm, if you measure fish ponds or mountains, this accuracy can also be used.

The fixed solution is the most accurate data, with an accuracy of 3-5cm, which can basically be used as a root point or directly used for lofting. Quietly.

Difference decomposition: There is a signal, but due to various reasons, such as the number of satellites is too small or the location of the mobile station is too poor, the accuracy of the intersection data is very low, and the general deviation is a few meters or more than ten or twenty meters.

For example: fixed solution: its positioning accuracy is within 1 cm, which can meet the topographic map surveying and mapping, construction lofting and root point measurement of various scales in addition to the first level control measurement and other high-precision requirements of the surveying and mapping work.

Floating-point solution: If the positioning accuracy of the floating-point solution is less than the meter, the plane and elevation error are generally in the meter according to experience, which can meet the surveying and mapping work with the accuracy requirement not greater than the meter; If the positioning accuracy is greater than meters, the plane and elevation errors are generally 1-3 meters for land beams.

The positioning accuracy of differential decomposition and single-point solution is generally between 5-10 meters, and sometimes it is larger, so it is generally not used.
