Driver for UM982 / UM980

• Driver for UNICORECOMM UM882/UM980 GPS
• Support NMEA, extended NMEA Instruction Set: PVTSLN, GNHPR, BESTNAV
• Support ASSIC Instruction Set Only now
• Get as much location information as possible ( more than stantad NMEA sentence )

Language

• English ( English version will be coming soom )
• 简体中文

Installation

pip install um982-driver

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

Examples

demo.py

from um982.assic_driver import UM982Driver
import serial

if __name__ == "__main__":
    um982_driver = UM982Driver()                # Instantiate the driver object
    ser = serial.Serial("/dev/ttyACM0", 921600) # Open the serial port
    while True:
        msg = str(ser.read_all(),'utf-8')       # Read UM982's output
        um982_driver.decode(msg)                # Decode
        # Output position-related information
        print(um982_driver.bestpos_lat)         # Latitude
        print(um982_driver.utm_x)               # UTM coordinate x (positive eastward)
        print(um982_driver.bestpos_latstd)      # Standard deviation of latitude, can also be seen as the standard deviation of UTM coordinate x
        print(um982_driver.bestpos_lon)         # Longitude
        print(um982_driver.utm_y)               # UTM coordinate y (positive northward)
        print(um982_driver.bestpos_lonstd)      # Standard deviation of longitude, can also be seen as the standard deviation of UTM coordinate y
        print(um982_driver.bestpos_hgt)         # Elevation (positive upward)
        print(um982_driver.bestpos_hgtstd)      # Standard deviation of elevation measurement
        # Output speed-related information
        print(um982_driver.vel_east)            # Speed in the UTM x direction
        print(um982_driver.vel_east_std)        # Standard deviation of speed in the UTM x direction
        print(um982_driver.vel_north)           # Speed in the UTM y direction

        print(um982_driver.vel_up)              # Vertical speed
        print(um982_driver.vel_up_std)          # Standard deviation of vertical speed
        # Output attitude-related information
        print(um982_driver.heading)             # Heading
        print(um982_driver.pitch)               # Pitch
        print(um982_driver.roll)                # Roll
