Remapping is necessary when the GNSS Antenna is relocated

1.Please do not move the GNSS antenna's location if not necessary (even just only a small move will affect the signal easily)

2.Not metal objects around the GNSS antenna

3.Try to ensure that no obstacle around the GNSS antenna (e.g. Tall trees)

4.Do not place the GNSS antenna close to the glass which will affect signal receiving and cause RTK issue furtherly
