3.4.3. SkyHub installation on the drone#

Warning

Power off the system when connecting cables. To avoid short-circuiting or causing potentially harmful power fluctuations, it is recommended to power off the entire system before performing any cable plug-in or unplugging. Some of the payload sensors used are extremely sensitive to power changes and may be damaged.

3.5. Components#

SkyHub assembly kit contains the following components:

  • SkyHub onboard computer

  • SkyHub 3 smart cable with the dovetail

  • Altimeter mounting bracket

  1. Physical assembly of the SkyHub is complete. Check that all the connectors are secured tightly, with no loose movements.

3.6.1. Altimeter installation on the drone and connection to the SkyHub#

To install the altimeter sensor on the IF800 Tomcat, use the mountings provided with the sensor.

Note

At this points, mounting bracked should be already installed on the drone.

For your convenience, we have a library with 3D models you can download and print yourself in case the default ones are broken or missing: https://files.ugcs.com/s/fMpj5LJpobWeMFi

  1. Slide the altimeter vertically on the previously attached bracket.

Note

If you wish to detach the sensor, simply perform the same action in reverse. Place the altimeter in the vertical position and slide it up from the gimbal.

  1. Connect the cable to Connector 1 (yellow) on the SkyHub.

  1. Setup is complete. You can now proceed with the widget configuration.

3.6.2. Altimeter / Autopilot configuration within the CPM software#

Before proceeding further, power on both the drone and remote controller. Then, make sure that your computer and the controller are connected to the same network. This is required to establish the drone link connection between CPM on your computer and SkyHub on the drone.

Note

SkyHub will take a little more time to fully boot up. You can check whether it is ready by the indicator within CPM. As soon as the SkyHub indicator becomes green, you can proceed with the configuration.
