@Eric-Katzfey 

In reference to the above-mentioned topic, does Starling2 currently utilizes only one tracking camera sensor (AR0114) for VIO? In addition, how does Triple tracking camera configuration utilized for the system VIO functionality?

@navin_kaviyarasu Our currently supported VIO method is only single camera. Our upcoming solution which we are actively testing and tuning is based on OpenVINS and works with multiple cameras.

@Eric-Katzfey What are the camera placement positions for the Dual Tracking Camera option for Starling2? Is it 1x front forward facing camera + 1x rear downward facing camera or 1x front forward facing camera + 1x rear backward facing camera?

@navin_kaviyarasu It is 1x front forward facing camera + 1x rear downward facing camera. We'll update the documentation to make that clear.
