6.  Common Commands Setup 

UB4B0M supports simplified ASCII format. Simplified ASCII format without checksum bits 

makes it easier for users to enter commands. All commands consist of a command header 

and configuration parameters (if the parameter part is empty, the command has only one 

header), and the header field contains the command name or message header. 

UB4B0M is simple and easy to use, and the common commands are shown in the 

following table: 

Table 6-1 Common Commands 

Command 

Description 

freset 

Restore factory settings 

version 

Query version number 

config 

Query the serial port status of receiver 

mask BDS 

Mask (disable) tracking of Beidou satellite system. BDS, GPS, 

GLONASS and Galileo can be disabled separately 

unmask BDS 

Unmask (enable) tracking of Beidou satellite system. BDS, 

GPS, GLONASS and Galileo can be enabled separately.   

By default, all satellite systems are tacked. 

config com1 115200 

Set com1 baud rate as 115200 

Com1, com2 and com3 can be set respectively as any one of 

9600, 19200,   

38400, 57600, 115200, 230400, and 460800 

unlog 

Disable all output from the current serial port 

saveconfig 

Save settings 

mode base time 60 1.5 2.5 

The reference point coordinates are automatically generated 60 

seconds after positioning or when the horizontal accuracy is 

better than 1.5m or the elevation accuracy is better than 2.5 m. 

After power off and restart, the new reference point coordinates 

will be calculated and generated again. 

mode base lat Lon height 

Manually set the reference point coordinates as: lat, lon, height 

(the coordinates do not change after the power off and restart) 

e.g. 

lat=40.07898324818,   

lon=116.23660197714,   

height=60.4265 

Note:

 The longitude and latitude coordinates can be obtained 

through the bestpos command; if it is the southern latitude, lat 

value is negative; if it is the western longitude, lon value is 

negative. 

mode base 

Set as base station 

mode movingbase 

Set as rover station 

mode rover 

Rover mode by default (The command can switch the receiver 

from the base station mode to rover station mode)
