A Drone by Aero-hawk so cleverly named the Field Hawk


Aero-Hawk  announces the arrival of Field Hawk. A new to the market Unmanned Aerial Vehicle. With the Field Hawk Farmers get a drone capable of providing useful information using Wavelength Specific Filters to Notice Chlorophyll Health, Cell Structure, and Water content. The Field Hawk was designed in house out of tough nylon, using high quality parts. Rising to the challenge of gathering usable plant information at a low cost. The Field Hawk can come equipped with either a 2 or 4 Camera array capable of 60 to 120 gigabytes of information storage. These cameras paired with the powerful yet simple AeroHawk Maps application gives the farmer an edge in efficiency in today’s competitive market. The advanced Flight Controller Pixhawk 2 Cube is operating this aircraft that is capable of fully autonomous missions with a flip of a switch. With a simple 2-axis gimbal the M series cameras get a clear  8 Megapixel image every time the shutter is triggered  Aero-Hawk has developed a full package of Hardware, Software, and Online Support so the farmer can not only just see the data but also use it In his everyday operation. Go check it out at https://aero-hawk.com/ 

On a similar note we are also a distributor for the Pixhawk 2 in the North West of the US. 

Thank you!

Autonomous boat to sail across the Atlantic – Proof of concept

One year has passed since I launched the autonomous boat OpenTransat that has attempted to cross the Atlantic Ocean and I wrote an article about it. The boat is lost in the ocean after being hit by crazy storms, but I didn't give up. Currently, I am working on the next sailboat with improved hardware and software and a more robust construction. Below is the picture of the design which is not final yet – it will be further improved in several aspects.

You see, it's based on interesting concept – a rigid wingsail that's adjusted by a "flap". It works much like an airplane wing. It's not something new – it has been used even on manned yachts:

However, I had no experience with this thing and I wasn't confident enough to believe it can work. Before going to spend a lot of time building a new 2-meter boat that will be designed for extreme ocean conditions, I've decided to build a 65-cm model to test and tweak the concept. Along the path, I've learned skills necessary to build strong composite parts.

The carbon fiber/Kevlar hull is filled with a closed-cell polyurethane foam and painted with a special antifouling paint. This kind of paint doesn't give as smooth finish as a gelcoat or normal paint, but it prevents subaquatic organisms from attaching to the hull.

A waterproof servo is used for steering. As this is just a model for lake testing, the IP67 rating is acceptable here.

The boat uses the same custom hardware and navigation software as the final design. The hardware is optimized for low power consumption and it includes plenty of sensors to provide more insight of what's happening with the boat. The program can be uploaded over Wifi which makes life a lot easier – I can debug and overwrite the program from the shore or motorboat. The battery provides enough power for 8 hours of continuous operation.

The wingsail is made from a foam wrapped with carbon fiber.

And here's the finished boat:

Check out the video of the boat sailing on a lake:

I'm happy to see it works!

Sputnik GIS 1.3 by Geoscan has been released!

Hello everyone!

                In Geoscan we develop multidimensional spatial data visualization system – Sputnik GIS. It is a great tool for viewing and analyzing wide range of UAV survey results.

                Today we are glad to present you a new version of Sputnik 1.3. In this version, we improved TLS rendering algorithm and released new features.  Please check out the list of improvements and innovations below.

  1. TLS rendering – the speed of rendering along with detail level increased, high FPS is maintained. The chance of coarse objects (LOD) appearing during model rotation is reduced.
  2. Close to wall navigation is improved – we added first person camera mode and keys combination to move along vertical axis of object
  3. Export part of TLS model – we added tool to export interested part of TLS model to OBJ, 3DS and DAE. For DAE and 3DS formats, backward compatibility with Sputnik is implemented
  4. WMTS support -  along with support of WMS services, Sputnik 1.3 supports WMTS services. Thanks to this innovation, you can use the maps you created on the Mapbox service. Also you can use GetFeatureInfo function.
  5. OC3 and LAS support – now it is available to view OC3 (Photoscan point cloud format) and LAS ( Lidar)
  6. Color palettes – from new version it is available to style raster maps in *.geotiff format
  7. Photo selection – new feature of photo selection for specified point makes Sputnik a great tool for analyzing condition survey results.

Try out new features of Sputnik GIS!

You can download trial version of Sputnik 1.3 using this link - https://www.geoscan.aero/en/sputnik/
