Timing related settings
mode base time 60 1.5 2.5
Automatically generate the reference point coordinates if
the positioning time reaches 60s or when the horizontal
accuracy is superior to 1.5m and the vertical accuracy is
superior to 2.5m. Automatically set the reference point
coordinates to repeatedly calculate and generate the new
reference point coordinates after power off and restart
Mode base lat Lon height
Manually set the reference point coordinates to lat, lon,
height (the reference point coordinates are not changed
after power off and restart)
For example: lat=40.07898324818, lon=116.23660197714,
height=60.4265
Note: If the position is south latitude, enter a negative
value in Lat; if the position is west longitude, enter a
negative value in lon
