Path is always behind GPS

[rayxie11]

‍Hello, I just saw your video on LIORF Mapping and I'm genuinely impressed. I implemented your code and the LiDar map produced was of extremely high quality. However, I do notice that during map generation that GPS location is much faster ahead of the generated path (blue line). Do you know what might be the issue causing this? Thank you so much!

@rayxie11 It may be caused by the accuracy of GNSS device.
