IMU614E-P Surveying and Mappin g IMU Batch Test Repor t of Forsense

1、Test conditions

^{l   Oblique plotting IMU：IMU614E-P of   forsense}

^{l   Base station：septentrio-mosaic X5}

^{l   Mobile base station：septentrio-mosaic X5}

^{l   RTK Antenna ： All-Channel Antenna}

^{l   Centering rod：2 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
