More Sea Hippies and DIY UAVs

Bit of an update on the Sea Shepherds post. First, nix one high speed vessel

from the fleet. Having a high speed intercept ship such as Brigitte Bardot or the former Ady Gil in the fleet makes a lot of operational sense, but running a 35 meter trimaran at speed in 6 meter seas, probably doesn’t so much.

Second, the post responses on this topic always amaze me. It is interesting how one non-governmental organization can be characterized in the comments by terms varying as widely as maritime eco-terrorist organization, vigilante group, hippies, and fishery enforcers.

Additionally, I’ve been corresponding with Jimmy Prouty, the creator of the Osprey UAS, who provided some corrections on my posted assumptions and additional information on his equipment. Some of the Osprey’s specs are competition sensitive and not readily available except to clients, but there are some interesting tidbits shown in the email excerpts below:

First, the Osprey is not at all modeled after the Scan Eagle. It is an optimized airframe with a high aspect ratio wing designed for maximum efficiency and range and it’s similarity with the Scan Eagle is only that it has a long wing and round fuselage.

For the most part, all of our aircraft are designed as airframes that can be adapted to any number of uses. While videography and vertical photography are the most popular uses we also have them being employed in nuclear/biological/chemical detection system test that would detect those agent in the event of a spill/disaster.

We also do custom airframe development and are currently working on three new designs of various sizes and capabilities. The Osprey has proven to be a very capable airframe and has seen a great deal of use in various areas including the development of cooperative soaring where two aircraft search for thermal lift and communicate the conditions with each other. The Osprey’s design lets it turn off the motor and circle autonomously in lift, conserving the main battery and greatly extending its range. A good example of this in nature is the sand hill crane – it thermals up to high altitude and then glides off looking for its next thermal during its migration. Ed note: I’m not sure if there are many thermals in the Southern Ocean, but this is certainly a useful capability for a STUAS

We work with clients to get them the range that they desire as we did with the Sea Shepherd. Advancing technology in Power systems (batteries, motors, etc) is really letting is stretch our legs. Low cost, reliable autopilots such as the AttoPilot have matured and become extremely reliable to the point that we can duplicate flight paths within 1 square meter accuracy while still being able to reroute ourflightpath or call the plane home with the click of a mouse. EO payloads are also evolving rapidly and have a lot of great use.

One of the biggest benefits of companies such as ours is that we can produce a high quality product for general use at a very affordable price with absolutely no cost to the taxpayer. The majority of the major UAS manufacturers rely on government funding (DARPA etc.) to develop their products and then turn around and sell them to the taxpayer at greatly inflated prices. We’ve proven that we (small business) can do it for a minimal investment, provide a high quality, safe product, and get the consumer exactly what they want.

Third, your assumption on the range of the video system are also off base. There are commercially available units that will provide excellent video reception well beyond the the 10km are reported in your article. There are several hobbyists that fly 25+ miles via video goggles and they don’t have access to the higher end video equipment that can be deployed our airframes. The system can also provide geo referencing to give GPS location for any picture or video that is shot during the flight for later review which doesn’t require a video downlink.

Hangar 18

has an interesting concept and I wish them well in their effort to commercialize affordable, yet tactically useful UAVs. STUAS of all types, including rotary wing platforms capable of launching from a vessel as small as a CB-90 are rapidly improving in performance and capability and will rapidly proliferate throughout the world’s navies (and non-state navies).
