M10G-5883

Introduction

• M10G-5883 GNSS module integrates the u-blox 10th generation receiver chip – M10050, and the magnetic sensor – QMC5883L. It supports all L1 GNSS signals (GPS/GLONASS/Galieo/BeiDou) and can use up to 32 satellites simultaneously for navigation.
• The high-gain 18 x 18 x 4mm patch antenna provides the best balance between performance and small size.
• Built-in flash, parameters can still be saved when module lost power.

Specifications

• GNSS Receiver: U-BLOX M10 (M10050)

GPS Setup Tutorial For INAV

1. Connect the GPS to the serial port of the flight controller, and then config the sensors function of the port which you connected as “GPS”.
2. In the GPS configure page, setup as the picture below: Enable the GPS function; Setup the Protocol as UBLOX;
3. Save and reboot, you will see the GPS icon light up(Blue).

GPS Setup Tutorial For Ardupilot

1. Correctly connect the M10G-5883 to the GPS serial port on the flight controller (usually serial3), rx to tx, tx to rx. And then configure SERIAL3_PROTOCOL to 5 (usually this is the default value).

2. Although most of the time Ardupilot’s default parameters will work with GPS, it is recommended to check the following parameters:

   GPS_AUTO_CONFIG = 1

   GPS_TYPE = 1or2

   GPS_DELAY_MS = 200 (sensor data delay params for ekf fusion)

   GPS_RATE_MS = 200 (gps data output interval)

3. Reboot the flight controller. You should see “GPS: No Fix” on the HUD of the Mission Planner, which means the flight controller has correctly recognized the GPS. If not, it shows “No GPS”.
4. To use GPS data in EKF fusion, the following parameters need to be checked, but usually these are default values:

   EK3_SRC1_POSXY = 3

   EK3_SRC1_VELXY = 3

   EK3_SRC1_VELZ = 3

5. At this point, the GPS has been set up and can be tested outdoors in an open environment. It is worth noting that starting from firmware 4.3.2, Ardupilot will force some configurations on M10: turning off the use of BeiDou B1L/GLONASS/SBAS. These configurations are solidified in the code and cannot be modified by parameter settings.

Compass Setup Tutorial For INAV

1. Install the M10G-5883 according to the direction shown below, and correctly connect the SCL and SDA to the flight controller.
2. Set the Magnetometer as “QMC5883” on the Configuration page, save and reboot, and you will see the Mag icon light up (blue).
3. Also on the Configuration page, set “MAG Alignment” to “CW 180°flip“, save and reboot.
4. On the Calibration page, click “Calibrate Compass” and follow the prompts to calibrate the compass. After the calibration is completed, save and reboot again.
5. Put the drone towards the north and check whether the heading value is around 0°. In order to prevent interference during flight, it is best to keep the GPS module away from the power output cable.

Compass Setup Tutorial For Ardupilot

1. Install the M10G-5883 according to the direction shown below, and correctly connect the SCL and SDA to the flight controller.

2. If “QMC5883L” can be displayed on the SETUP-Compass page of Mission Planner, it means that the compass sensor has been correctly recognized by the ardupilot.

3. Find an environment without magnetic interference, click “Start” to start calibrating the compass sensor, and continue to rotate the drone around each axis until the calibration progress bar reaches 100%. After the calibration is completed, MAG_CAL_SUCCESS will be displayed and reminded to reboot the flight controller.

4. It is important to note that the default value of the COMPASS_AUTO_ROT is 2, which means that ardupilot can identify the compass installation direction and automatically set the direction parameters after completing the compass calibration. But sometimes unexpected situations may occur. When ardupilot can’t recognize compass direction correctly, the calibration progress bar will repeat over and over again, and the compass calibration cannot be completed. If this problem occurs, you can manually set the compass direction parameters and turn off the automatic recognition function:

   COMPASS_AUTO_ROT = 0

   COMPASS_ORIENT = 6
