1、Test conditions

l   Oblique plotting IMUIMU614E-P of   forsense

l   Base stationseptentrio-mosaic X5

l   Mobile base stationseptentrio-mosaic X5

l   RTK Antenna All-Channel Antenna

l   Centering rod2 m

2. Test point

Headquarters Roof of Forsense,Pudong New Area, Shanghai

3. Test method

The surveying IMU614E-P from Forsense israndomly selected. Each IMU module obliquely measures the base error of thepole at 8 coordinate points, each coordinate point at 35 degrees of inclinationand four directions near 15 degrees of inclination, respectively, to make errorstatistics.

Inorder to get the reference point of coordinate true value, the reference pointis collected as coordinate true value by bubble pair method at each location.

5. Conclusion

In the open scene with good RTK Positioning, the performance of primitive mapping

IMU in batch test is as follows:

Level error The error within 2.5cm accounts for 99%

The error within 3 .5cm accounts for 100

High error The error within 2.5cm accounts for 99%

The error within 3 .5cm accounts for 100
