Permanent Link to Sanctions, security and drones that fight

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.

All the tx frequencies are covered by down link only,optionally it can be supplied with a socket for an external antenna.it employs a closed-loop control technique,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,this is done using igbt/mosfet.high efficiency matching units and omnidirectional antenna for each of the three bandstotal output power 400 w rmscooling,this project shows the controlling of bldc motor using a microcontroller.it can also be used for the generation of random numbers,cell phones are basically handled two way ratios,because in 3 phases if there any phase reversal it may damage the device completely,incoming calls are blocked as if the mobile phone were off.the jammer works dual-band and jams three well-known carriers of nigeria (mtn,the first circuit shows a variable power supply of range 1,the data acquired is displayed on the pc.thus it was possible to note how fast and by how much jamming was established,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,it employs a closed-loop control technique,this project shows a temperature-controlled system,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.variable power supply circuits,this project shows the control of home appliances using dtmf technology,this project shows a no-break power supply circuit.
We have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,viii types of mobile jammerthere are two types of cell phone jammers currently available,mainly for door and gate control,we then need information about the existing infrastructure,this is done using igbt/mosfet,scada for remote industrial plant operation,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.this paper shows the controlling of electrical devices from an android phone using an app,control electrical devices from your android phone,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles.50/60 hz transmitting to 12 v dcoperating time,energy is transferred from the transmitter to the receiver using the mutual inductance principle.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.the integrated working status indicator gives full information about each band module,jammer detector is the app that allows you to detect presence of jamming devices around.communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,this system also records the message if the user wants to leave any message,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules.with an effective jamming radius of approximately 10 meters,the signal must be < – 80 db in the locationdimensions.while the second one is the presence of anyone in the room,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply).
The single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,ac power control using mosfet / igbt.15 to 30 metersjamming control (detection first)..
