Usage

UM982 Configuration

It is necessary to enable the serial port output of the UM982 for PVTSLN, KSXT, GNHPR, BESTNAV statements, with the command format as

<output statement name> <output COM port> <output frequency>

Specific command examples are as follows (output to UM982's COM2, baud rate 921600, output once every 0.05 seconds):

config com2 921600
PVTSLNA com2 0.05
KSXT com2 0.05
GPHPR com2 0.05
BESTNAVA com2 0.05

    um982_driver = UM982Driver()                # Instantiate the driver object
