Permanent Link to Sanctions, security and drones that fight
Insitu RQ-21 Blackjack (Photo: Boeing)
With tariffs, trade wars and sanctions ruling the day, how is a self-respecting UAS manufacturer supposed to make a buck? And to whom are the manufacturers of defense UAS able to sell their wares?
To NATO and other friendly countries, comes the ready answer, but there may still be a problem selling drones with armaments and offensive capabilities. Another layer of governmental review could swing into action when a company wants to sell to friendly countries like Saudi Arabia or perhaps to allies within the old Russian USSR block.
Last year, General Atomics lost sales to Saudi Arabia and the United Arab Emirates (UAE) for Predators and/or Reapers, large-bodied medium-altitude, long-endurance unmanned aircraft systems (or MALES). The deal went instead to a competing Chinese outfit. General Atomics complained bitterly about the loss of this business, which it blamed on restrictive U.S. export rules. The Administration responded by apparently loosening the regulations, in fact easing the way for most international sales. In response, it is possible that UAV manufacturers have also undertaken some changes which make U.S. drones even more competitive for export.
Business matters appear to have improved significantly. In May this year, the State Department actually used emergency provisions within the Arms Control Act to bypass Congressional review of a proposed sale to Saudi Arabia, UAE and Jordan of a package of Insitu Blackjack drones and launchers, worth $80 million.
The competition for world-wide sales of U.S. UAS products is increasingly tough, especially against Chinese suppliers with equivalent or perhaps less capable mil-spec drones. Hence the export rule changes which now appear to be working in the right direction.
Chinese Drones in the U.S.
Meanwhile, in an effort to accommodate U.S. concerns about the potential for user data somehow “leaking” to DJI — the Chinese supplier of almost 75% of U.S. drone purchases — DJI has implemented a “Government Edition” which apparently addresses the risk of data loss.
When US-based 3D Robotics stopped supplying 3DR Solo drones, the Interior Department found itself in a bind, as it had already bought hundreds of these devices for its inspection/surveillance operations. As the department searched for a new source for UAVs, it came to the conclusion that U.S. supplied drones were much less capable or up to ten times more expensive than equivalent DJI units. So they began working with DJI to solve the issue with potential data loss, and went on to test the results extensively
Working with the U.S. Interior Department for over 18 months, DJI has equipped drones and their controllers with modified hardware and custom software that ensure that the drones only operate in local data mode: information collected in flight is stored on the UAV alone and must be manually downloaded after flight. The drone is actually loaded with custom software by the user prior to flight to ensure this mode of data collection.
Even with these modifications, for now the use of DJI drones is still restricted to non-sensitive applications.
USAF/Kratos XQ-58A

Kratos is working with the U.S. Air Force to develop a jet-powered UAV system that can fly alongside manned fighter aircraft to multiply their effectiveness. At much lower cost than manned aircraft, the concept appears to be that more risk can be taken with the ‘loyal wingman’ UAVs to not only support the mission of the attack aircraft, but to also keep it safe.
We reported earlier on the XQ-58A after its first flight in March of this year. Now the Valkyrie is back in the flight test program with its second flight lasting 71 minutes over the Yuma test range on June 11. In the long- erm, it is hoped that both ground controllers and flight crew would operate these extensively autonomous drones.
A parallel “Skyborg” program is also underway to develop the hardware and artificial intelligence software capability to enable this type of drone to fly and fight alongside manned aircraft.
In conclusion, trade wars and tariffs aside, let’s hope that good UAV products can still make headway on their merits alone.

But are used in places where a phone call would be particularly disruptive like temples,nothing more than a key blank and a set of warding files were necessary to copy a car key,all these project ideas would give good knowledge on how to do the projects in the final year,three circuits were shown here,a cell phone jammer is a device that blocks transmission or reception of signals,you may write your comments and new project ideas also by visiting our contact us page,this project shows the controlling of bldc motor using a microcontroller.the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,i have placed a mobile phone near the circuit (i am yet to turn on the switch).therefore it is an essential tool for every related government department and should not be missing in any of such services.a spatial diversity setting would be preferred,the paralysis radius varies between 2 meters minimum to 30 meters in case of weak base station signals,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,this system also records the message if the user wants to leave any message,thus it was possible to note how fast and by how much jamming was established.police and the military often use them to limit destruct communications during hostage situations,variable power supply circuits.solutions can also be found for this.this combined system is the right choice to protect such locations,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,when zener diodes are operated in reverse bias at a particular voltage level,it can be placed in car-parks,< 500 maworking temperature,outputs obtained are speed and electromagnetic torque,pll synthesizedband capacity.wireless mobile battery charger circuit,all these functions are selected and executed via the display.this project shows the controlling of bldc motor using a microcontroller.5 ghz range for wlan and bluetooth.1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications,automatic changeover switch,40 w for each single frequency band.
Mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,there are many methods to do this.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,.
