Hi Everyone-
I am an oceanographer and I am using a ship-tethered aerostat to acquire imagery of the ocean. I have a Canon EOS 5DSR mounted on my aerostat and I want to transfer stills (jpegs) from the aerostat to the ship. I trigger the camera using a python script that's running on an odroid. I store the images on an external drive and I need to transfer images from the aerostat to the ship so we can monitor the field of view and adjust position, altitude if necessary.
I have been using a ubiquiti wireless point-to-point (5 GHz) but it's very unreliable. I have to reset each antenna and reconfigure each time. Annoying as well.
Can anyone recommend an alternative?

Dan,
aerostat or blimp this is exactly what I have built to harvest airborne energy (project by New York Academy of Sciences and some guys).
Tell me what is a distance between your ship and aerostat and at what altitude it is flown.
If distance is low you can arrange for tethered data transfer and charging at the same time.
WiFi enabled SD card is one solution, pointing directional dish antenna (Yaga inside) to your aerostat (8 years old technology)
I have tested $10 used HP WiFi printer coming with SD memory slot to emulate WiFi SD card for me, since you can establish WiFi connection to SD card inserted into printer from WiFi tablet.
Either way distance makes the difference.
Google and a number of companies already have had plans to establish Internet access
via network of aerostats (self-configurable mesh network) for off-grid, off-telephony regions.
Could you attach some images of your aerostat ?
Hi Dan,
Did you come up with a solution to this problem?
I imagine that the aerostat and ship move quite a bit in all directions.
What kind of antenna are you using on your ubiquiti system?
