Cloudless climbs to 21km - sUAS News - The Business of Drones




Cloudless made another flight in an electric, unmanned plane at an altitude of up to 21 kilometres. Cloudless engineers successfully completed a 30-minute horizontal test flight at an altitude of over 13,000 meters.



The Cloudless startup, founded by two Polish engineers, performed another successful flight of a stratospheric UAV at an altitude of over 21 km in mid-December.









After less than an hour of ascent under a special balloon, a large – with a span of 5 meters – UAV was released. During the 2.5-hour flight, environmental parameters were tested, and then a landing was made at the planned location. The winter flight took place with the passage through the area of unfavourable weather conditions, such as icing and strong winds (jet streams). This is the fourth stratospheric exploration flight this year.



During the last flights, components such as photovoltaic panels, a new type of propulsion and new batteries were tested. In the last flight, in December, a test flight was also carried out, which lasted 30 minutes. This test confirms the theoretical assumptions and enables further work to be carried out towards longer and longer flights in the stratosphere.



Engineers also developed a system of stratospheric imaging of the Earth, the result of which are aerial photos (georeferential image data) with a resolution exceeding VHR (very high resolution) satellite imaging. Large-scale terrain mappings (thousands of hectares) can be delivered in one day. It is one of the few imaging solutions in the world from such high altitude using an unmanned aerial vehicle.



The designed UAV also allows placing sensors onboard for measuring the parameters of the atmosphere, e.g. pollution or dust after volcanic eruptions. Thanks to this, it will be possible to conduct measurements in conditions that would endanger conventional manned aviation. There are situations in which the airspace is closed due to volcanic ash dangerous for civil aviation. One such incident occurred in 2010, when the Eyjafjallajökull volcano erupted shutting off Europe’s airspace for several days.



Another application of the stratospheric plane is testing solutions intended for the space industry. For this purpose, cooperation has been established with the Polish company Thorium Space, with which the concept of research flights with innovative space telecommunications systems is being developed.



Stratospheric flights will allow for a better study of radio wave interference as it passes through the troposphere – the densest layer of the atmosphere.



In addition to research applications (environmental protection, meteorology, space engineering), Cloudless engineers use it to work on a pseudo-satellite (HALE / HAPS), i.e. a stratospheric aircraft that will be able to stay in the higher parts of the Earth’s atmosphere for a long time. Pseudo-satellites will fill the gap between aircraft and space satellites. Unmanned aerial vehicles powered by solar energy will be able to stay in the stratosphere continuously for weeks and months, and ultimately even a whole year.



Drones of this type are many times cheaper to produce and use than satellites, and they enable, among others, Earth observations with greater accuracy in real time. The absence of most weather phenomena in the stratosphere makes it possible to use 100% of the potential of solar panels.



The plane was completely designed and made by the Polish company Cloudless, it is an innovative research platform on a global scale. The plane has been approved for flights according to the latest regulations of the European Union Aviation Safety Agency. Preparatory work was supported by the Institute of Technology and Life Sciences – National Research Institute.

The Cloudless startup can boast of interesting achievements, so far they have done, among others the highest known flight of a drone released from a balloon at an altitude of 27 232 m above sea level. (on 30/03/2019), horizontal flight in the stratosphere using an electric drive, flight with photovoltaic panels or return to the planned landing sites with an accuracy of several dozen meters. Pseudo-satellite projects have been and are being developed worldwide by subsidiaries of such giants as Airbus, Facebook, Google, BAE Systems and HAPSmobile.

DJI Mini 2 Errors: What They Mean (And How to Fix Them) | Droneblog

Image
Nothing brings a drone operator down quicker (pun intended) than bad weather and drone error codes.  We wait until it gets better with the weather, eventually, although our highly anticipated day of flying is ruined.  However, drone error codes can be more than simply waiting out the issue or hoping it resolves itself. Error codes and the inability to fly the DJI Mini 2 because of these errors can be a nuisance, but, when those codes are decoded, explained, and suggestions on how to fix the issue come to the fore, things get easier. We’ll be looking at a laundry list of DJI Mini 2 error codes, what they mean, and the steps to fix them.  The codes will be listed numerically to locate specific codes easier within the article. These codes are: Code 10001Code 10016Code 10022Code 10023Code 30007Code 30008Code 30047Code 30049Code 30050Code 30055Code 30060Code 30064 Code 30085Code 30105Code 30168Code 30210Code 30224Code 30226Code 40002Code 40011Code 40012Code 40021Code 180016Code 180030Code 1...

DJI Transmission System (Everything You Need to Know)

Image
An essential feature behind a DJI drone that is often overlooked is the drone transmission system. I have personally flown multiple DJI drones from different generations, and I can say – good heavens, what a difference! DJI drones usually have the OcuSync transmission system, which is unique and proprietary to DJI. The transmission module is installed on all DJI drones and cannot be upgraded or changed, but it comes in different versions. And the flight range, penetration, controller compatibility, and a few more factors depend on it. Here, I’ll share with you everything you need to know about the DJI transmission system, why it matters, the difference between them, and how we can identify one. Behind DJI OcuSync: Factors & Analysis A transmission system in a drone is one of the most critical parts without which a drone cannot fly at all. It simply cannot make a connection between a drone remote controller and the drone itself. In consumer DJI drones, we have the OcuSy...

Autel EVO 2 Pro: 3 Most-Common Problems (With Solutions) | Droneblog

Image
The Autel EVO 2 Pro drone is a very powerful drone with many features, but it does have a few drawbacks that I have found while using it. Despite the issues I have experienced, the Autel EVO 2 Pro is still a great drone that I would recommend to anyone looking for a foldable drone with a 20MP camera. While the Autel EVO 2 Pro is a strong drone model overall, there are a few areas of weakness. The controller, lack of accessories, and flight characteristics could use some work on Autel’s end to get this drone to the top of its class. Even with the problems I have experienced, there are still many ways to fly the EVO 2 Pro issue-free. Let’s take a closer look at some of the issues you might experience and ways to work around them to get the footage you’re looking for. 1. Autel EVO 2 controller issues As a professional drone operator, I have used a few different drone controllers and think the controller that comes with the EVO 2 Pro is just too small and not balanced properly. Let’s discu...
