After communicating with BDStar’s technology, we got BDStar’s method of measuring RTK accuracy:
1. Put RTK at a certain point for a month, filter and average the data of one month to get the average value, and take the average value As the expected value of the modified point (based on the relationship between statistical data and probability data), the expected value is taken as the true value. This point is used as a standard point to test the accuracy of RTK.
2. Accuracy: Latitude and longitude and height are marked separately; the latitude and longitude data measured by RTK are converted into two-dimensional plane coordinates, and a circle is drawn with the origin of the coordinates. All points within a range fall in the circle, and the radius of the circle is used as the accuracy. The height is also to fit the statistical data, 1
as the precision.
