| The images are stored on the two Raspberry Pi Zeros. The Image download station provides image download via two parallel Wifi links from the drone. The image download station is based on two [[https://www.gl-inet.com/products/gl-ar750/|GL-AR750]] access points. The datatransfer itself is handled by rsync via its rsync protocoll which doesnt rely on SSH. SSH is not used as the pi zero is not fast enough to encrypt the huge data we want to transfer for each flight. | The images are stored on the two Raspberry Pi Zeros.
