- When you need to use head tracking to control a gimbal or other devices.
- Head tracking works by having the ground-side goggles collect gyroscope, accelerometer, magnetometer, and other data, which is then transmitted wirelessly to the air unit. The air unit then outputs the control signal to the gimbal.
Ascent Goggles only supports Ascent series air units and cannot connect to the Avatar air unit system.
- This upgrade module is not included as a standard accessory, and you may need to purchase it separately.

- This depends on your needs. XT60 connectors are commonly used in RC models.
- Update both the ground-side receiver and the air unit in the Avatar / Ascent system to the latest versions.

¶ Step 3 Connect the Power Cable and Control Cable

- When using a GM V1 series gimbal, because version V3.6 added support for the Axis Lock function, all control channels must be set to CH01.

- GM V2 series gimbals do not require any additional settings. They can start working after the cables are connected.
- The head tracker module can output a PPM signal, allowing it to connect to a third-party radio transmitter.
- Avatar Goggles X and Goggles L are used here as examples.

When using a GM V1 series gimbal, make sure to set the channels to CH01 and write the settings to the device. Otherwise, head tracking will not be able to control the gimbal.
