Nextvision Nighthawk2 / Colibri2 / Raptor (with Trip2)
What you will need for this step
Skynode Enterprise (powered as described in Power Skynode)
Pixhawk Payload Bus (connected as described in Pixhawk Payload Bus)
Microhard Air Unit (optional - connected as described in Data Link Module
Cable provided with the Nextvision payload
Nextvision Nighthawk2, Colibri2 or Raptor payload (not included in the kit)
Nextvision Trip2 (not included in the kit)
Preparation
To access the payload settings you need to connect the payload via Ethernet to your computer. The default IP address for Nextvision is 192.168.0.201. This means you need to assign a static IP address on your computer's Ethernet that is in the same subnetwork (eg. 192.168.0.10) as the Nextvision camera. The next section goes through some of the payload settings that we will change to be compatible with the Auterion setup. These include:
The default Skynode Ethernet network is 192.168.168.0/24 instead of 192.168.0.0/24
The default Skynode video format is MP2TS instead of RTP
The default Skynode Nextvision protocol is mavlink extended
Network Settings

Mavlink Settings
Mavlink Ground Crossing Height Source: Mavlink Packet - SetGimbal
Execute Mavlink Flight Plan: disabled
Mavlink Heartbeat Source: GCS Port
System Mode Settings
Joy Movements During Pos. Modes: Disabled
System Mode After Track Loss: GRR (If a valid CFoV coordinate is available, a POI will be set on the last tracked location instead)
Tracker Settings
Enable Relocking (optional)
Camera Settings
Enable Full Ack Mode: disabled
Camera Initial Mode: Observation
These camera settings need to be set according to the position of the gimbal in relation to the vehicle:
Set to Belly or Nose according to vehicle
Enable Camera Image Flip if necessary for vehicle
Geo Calibrate according to vehicle, if there is a rotational offset between autopilot and gimbal a calibration is needed.
OSD Settings
OSD Mode: Disabled
OSD Mini Map: Disabled
RC Settings
Auterion Systems support the use of a RC to control the gimbal. If used:
Enable Remote Control
Select channels for the functions
Setup
Connect the camera to the Trip2 computer.
Connect the Trip2 computer to the Pixhawk Payload Bus Adapter Board using the JST-GH to Ethernet RJ45 cable that is provided with the payload.
Follow the instructions in General Setup. This section is the same for all payloads.
IP Settings with Microhard Air Unit module connected
The default Microhard DHCP server will assign an IP address in the range 192.168.168.100 - 192.168.168.200 to Skynode.
IP Settings without Microhard Air Unit module connected
In this case, there is no DHCP server that will assign an IP to Skynode, therefore you need to set a static IP, such as 192.168.168.100.
Login into Skynode via SSH
Create the file /data/override.env
Add the following environment variables
Reboot Skynode
Features
Tracking Mode: The gimbal follows the selected target
Point of Interest: The gimbal locks on a geo coodinate. It can be set by selecting the location on the map or on the video feed.
GRR: The system compensates for angular and translational movement of the platform. It will attempt to maintain the ground crossing location in the center of the image.
Observation: Similar to GRR, but the gimbal does not compensate for translational movement of the platform. For example: If the gimbal is looking north, and the vehicle turns, the gimbal will continue looking north.
LPOS: Gimbal remains in fixed position relative to the vehicle.
EO: Switch to electro-optical image sensor
IR: Switch to thermal image sensor
Switch between photo and video mode
Take a picture or start and stop recording a video
Open the settings
Zoom in
Zoom out
Current Field of View (changes with zoom)
Virtual Joystick, only shown if enabled in the settings
Current Angle of the gimbal
Cancel POI: Only shown if a POI is set
Center Field of View
Set Camera Projection in the camera settings -> Settings to enabled. This will display a projection of the field of view on the map, with the center of the field of view marked with a yellow marker.
In addition the center field of view coordinates are displayed on the upper edge of the video stream and the map. Selecting the coordinates will freeze them to make reading them easier.
Figure 8
For VToLs AMC offers the feature of flying in a figure of 8 to keep a point of interest in the field of vision without hitting the yaw limit of the gimbal. Simply set the 8 on the map, after setting a point of interest the 8 will automatically be realigned to keep the point always in the field of view.
