Как всё круто, какая польза от этого и ваще.
One pilot project in a protected area in Kenya saw a 96 percent reduction in poaching after it began patrolling with drones. Ditto with a WWF-funded project in Nepal, although in the Nepalese case, the drones were part of a larger overhaul in how rangers conducted their business. These successes, plus various other projects in the works, raise the possibility of a major advance in conservation — a leap enabled by drones.

И в процессе обсуждения на одном из форумов выступил человек с весьма интересным опровержением представленных цифр и фактов.
That's what Air Shepard, a South African based project, were trying to raise (https://www.indiegogo.com/projects/air-shepherd-drones-stop-elephant-rhino-poaching#/).
I came to slightly higher figures in my research. An extremely rough breakdown would look something like this:
- 2 x UAV Factory Penguin B/C or equivalent airframes, avionics, and ground equipment ~$240,000 USD
- 2 x stabilised thermal imager payloads ~$90,000 USD
- 2 x long range encrypted digital video links ~$50,000 USD
- 3 x professional UAV pilot salaries (required for proper fatigue management) ~$195,000 USD Ranger training, communication equipment, and infrastructure ~$50,000 USD
I imagine most people here would look at that figure a scoff. I admit I did too before I gained some experience. I know now that there's a few common mistakes that 'amateurs/hobbyists' typically make when estimating the cost of these sorts of projects.
They base project costs on material components, and ignore the extensive research, development, and refinement required to produce a system that will survive the harsh conditions in the field.
They assume solving the problem is as simple as getting a FLIR sensor in the air, and keeping it there for a reasonable amount of time.
They don't appreciate the need for things like reliable and encrypted video links. Poachers are both sophisticated, and well networked. If they can intercept your analog FPV system, it can lead them right to the assets you're attempting to protect.
They underestimate the technical expertise required to operate systems carrying extremely expensive payloads at night, underestimate the time required to properly train local operators, and don't budget for operator labour.
They don't take into account maintenance requirements. A 500 hour TBO (time between overhaul) only gives ~60 days of operations. An engine designed for hobby use might only have a TBO of 100 hours or less.
They don't take a holistic view of the workflow, and the equipment, ranger, and operator training this requires to develop.
I have no doubt that a tool can be provided to rangers for cheaper than this, but it's going to require collaboration (particularly among NGOs and researchers that have carried out field trials), mass production, and technological developments. I'm still actively working on it, but it's not an area that pays well, so my progress is hindered by a lack of resources.
Это всё к вопросу - насколько эффективны и дёшевы реальные, профессиональные БАК.
Возить коптером бумажки через реку - конечно бизнес, спору нет. Может быть полезный и недорогой.
Летать пенолётом за 100 баксов над саванной и высматривать браконьеров - тоже хорошо и полезно. Но вот на самом ли деле получаются такие результаты, о которых пишут?
Из личного опыта могу сказать, что в подавляющем большинстве случаев пилотируемый аппарат выходит дешевле.
