Rowland commented on Rowland's blog post New AreoHawk in Service"Sure thing. I think the key point is that this industry is complex and people always try and over simplify capabilities. As soon as you are dealing with the environment the cards are stacked against you."
Mike commented on Rowland's blog post New AreoHawk in Service"Rowland, please don't get me wrong - I was just pointing out that in scheme of things it is not a noteworthy cost factor. However, the statements of Kryzs and yourself are quite vaild and real issues and the approach is also valid. As is mine!…"
Rowland commented on Rowland's blog post New AreoHawk in Service"Mike, we agree but we found a significant increase in efficiency with our new UAV and were excited, so hence the focus on Sq/km. One thing we have found from years of commercial experience is that you do need to be able to do reasonably…"
Mike commented on Rowland's blog post New AreoHawk in Service"Kryzs, yes and no! Equal lighting can be sorted easily and effectively in post - I have software that does that automatically with great results and using RAW gives an even wider range of available adjustment.
I prefer slower planes anyway as…"

"Yes and no. If you require equal lighting and even more you are photomapping construction site, it is good to have one long flight.
Also because the smallest mishap would force you into option: repair SMALL issue on the field and make the second…"
Mike commented on Rowland's blog post New AreoHawk in Service"Krzys - the flight time is relatively trivial in the scheme of things - unless we are talking days. Getting to the site, good ground control and photo processing are where the real time is taken - so as far as marketing goes the km2/hour is a…"
ModeratorKrzysztof Bosak commented on Rowland's blog post New AreoHawk in Service
"Yes they use the AUW very efficiently. What most ppl dont realise on this market is that the more elongated the surface is, the easier is to get high total surface. As a result we have photo_width*(flight_time*airspeed) surface best case, but this…"

"That's a very pretty airframe, I like!"
Rowland commented on Rowland's blog post New AreoHawk in Service"Oops and I have been told off by one of our staff, the acquisition was complete at 42 min not 36. I recall 36 min for the task complete and we continued for another 6 min for some extra. This was the first time I had flown for a…"
Rowland commented on Rowland's blog post New AreoHawk in Service"Yes processing is king, especially with wide angle lens. Its taken 18 months for Areo to fully optimise for this type of aquisition. Its hard to say what the side overlap is, I think you're right - 50% is about right but…"
ModeratorKrzysztof Bosak commented on Rowland's blog post New AreoHawk in Service
"Nice example. 3 legs and... by eye... 50-60% side overlap? That sounds reasonnable."
Rowland commented on Rowland's blog post New AreoHawk in Service"We have a wider horizontal viewing angle and 20 Megapixel sensor and we are not flying a strict grid nav waypoint flight plan. In NZ the terrain is very copmplex. Attached is the evidence. Gorund speed ranges from 50 - 90…"
ModeratorKrzysztof Bosak commented on Rowland's blog post New AreoHawk in Service
"Assuming 65.5deg horisontal viewing angle, from 600m AGL you have ground photo width best case 772m.
From 14.6mpix digicam you have 17.5cm/pixel resolution from that altitude, BTW.
With that high altitude, merely 80% overlap and camera looking wide…"

New AreoHawk in Service
Posted on October 22, 2011 at 5:30pm 15 Comments 0 Likes
RQ-84Z AreoHawk is now is service in NZ after a months trial in Canada and NZ. We are acquiring 8 Sq/km in 36 min from 400-600 AGL and endurance 90 min+ -in 25 km 'hr winds.
Sensor is Sony Nex-5, Migrating to Sony Nex-7 in one week (when they arrive). Our Terrain Aware IP allows for dynamic operations factoring in wind direction, DEM, overlap requirements and acquisiton rate depending on ground speed.
No need for catapult. Parachute recovery (automated) and…
