Rajoituksia halvoille lentohärveleille @USA:
"Kauko-ohjattavilla lennokeilla on häiritty lentokoneita, tunkeuduttu Valkoisen talon alueelle ja yritetty toimittaa huumeita vankilaan. Yhdysvalloissa pohditaan nyt uusia sekä teknisiä että laillisia rajoituksia lennokkien käytölle, Bloomberg Business kertoo.
Yleistymään päin oleva tekniikka ovat geoaidat, paikannusteknologiaan perustuvat rajoitukset sille, pääseekö lennokki tietylle alueelle. Niiden suurimpia ongelmia on, etteivät geoaidat pysäytä halpoja lennokkimalleja, joissa ei ole gps-paikannusta. Lisäksi järjestelmät ovat toistaiseksi suhteellisen helposti hakkeroitavissa ja alttiita muillekin väärinkäytöksille.
Geoaita ei ole fyysinen este, ja se on siten myös näkymätön. Maailman tämän hetken suurin lennokkeja harrastekäyttöön valmistava yritys, kiinalainen SZ DJI Technology, sisällyttää valmistamiensa lennokkien järjestelmiin jo 6700 ”aidattua” aluetta, jonne niillä ei joko pääse tai, joissain harvemmissa tapauksissa, lennokin ohjaajaa vain varoitetaan alueesta.
Tänä vuonna lennokkien epäillään aiheuttavan yli tuhat ikävää välikohtausta esimerkiksi häiritsemällä lentoja tai tunkeutumalla kielletyille alueille. Kalifornialainen demokraattisenaattori Dianne Feinstein on tehnyt aloitteen kauko-ohjattavia lennokkeja koskevan lainsäädännön tiukentamisesta Yhdysvalloissa.
Ehdotuksen mukaan muun muassa yksittäisen lennokin sijainnin ja korkeuden pitäisi olla koko ajan tiedossa sen ollessa lennossa; sen pitäisi signaloida sijaintiaan jatkuvasti. – Tällaisen velvoittaminen on mielestäni oikeutettua, vaikka se nostaisi lennokkien valmistuskustannuksia, aloitetta kannattava demokraattisenaattori Richard Blumenthal Connecticutista sanoo. – Emmehän me myy halvempia autojakaan ilman turvavöitä ja –tyynyjä, hän perustelee."

'CIA launches secret drone campaign to hunt down top ISIS terrorists'

ShowImage.ashx


American commandos and the CIA have jointly launched a secret drone operation to track down and kill senior Islamic State (ISIS) terrorists in Syria, The Washington Post is reporting in Wednesday editions.

According to the Post, the campaign is an independently run initiative that is separate from the overall military effort being waged against the extremist movement by the US and other regional allies.

The new campaign is considered to be an escalation of the CIA's involvement in the war against ISIS. Thus far it has yielded results, including the recent killing of a British national thought to be behind ISIS' social media efforts.

According to the Post, American counter-terrorism officials say that the secret plan is the latest indication that decision-makers in Washington now view ISIS as a more menacing threat than al-Qaida.

US officials told the Post that while the CIA has taken a more active role in identifying and locating so-called "high-value targets," the actual targeted killings of these individuals is being carried out by special forces - also known as Joint Special Operations Command (JSOC).

The US military confirmed on Friday that a British hacker who was one of ISIS's top computer experts and active in encouraging people abroad to carry out "lone wolf" attacks was killed in Syria by a US air strike.

Junaid Hussain of Birmingham, England, was killed on Aug. 24 by a US military air strike on the Islamic State stronghold of Raqqah, said Air Force Colonel Pat Ryder, a spokesman for US Central Command.

Hussain had been involved in "actively recruiting ISIL sympathizers in the west to carry out 'lone wolf' style attacks," Ryder said, using an acronym for the militant group that has seized large parts of Syria and Iraq.

The CIA has pioneered the use of drones to intercept senior terror suspects. Its growing involvement in the war against ISIS is a reflection of the Obama administration's frustration over the failure to curb ISIS' expansion through the use of conventional military means, The Washington Post reported.

The JSOC also has an extensive track record in eliminating top terrorist suspects, including al-Qaida leader Osama bin Laden.

Just as we’re getting used to the idea of drones flying overhead, the University of California-San Diego has figured out how to make them invisible.

While making a drone literally invisible isn’t possible, covering it in a sheet that reflects its surroundings — like a fluid mirror — has a similar effect. The UCSD researchers just published their work in the journal Progress In Electromagnetics Research and, yes, they can do that.

Onko kiinalla omaa GPSää vastaavaa paikannusjärjestelmää?
 

DARPA recently conducted an experimental demonstration of Robotic Landing Gear. Replacing standard landing gear, the adaptive system consists of four articulated, jointed automated legs that are able to bend and fold up next to the helicopter’s fuselage while in flight. Each leg has an integrated force-sensitive contact sensor in its foot. During landing, each leg extends and uses the sensor to determine in real time the appropriate angle to assume to ensure that the helicopter stays level without risking the rotor touching the landing area.

Having the ability to land on and take off from angled, irregular and moving surfaces would greatly expand the effectiveness of helicopters across many military and national security missions.

Robotic Landing Gear is being developed by the Georgia Institute of Technology with funding originally from DARPA’s Mission Adaptive Rotor (MAR) program, which concluded last year.

Kätevä. Mitä pitemmälle mennään, sitä monikäyttöisemmäksi dronet tulevat.

We’ve seen aerial robots constructing things with rigid elements before, but that’s hard, because your localization and control has to be dead-nuts accurate, and the weight of the stuff that you’re hauling around puts severe limitations on the endurance. So the researchers—the project is a collaboration between ETH Zurich’s Institute for Dynamic Systems and Control and architecture firm Gramazio Kohler Research—decided to try something different. Their idea of using rope (specifically, polyethylene fiber, which has a high strength-to-weight ratio) takes into account what quadrotors are good at, and for many applications (like lightweight bridges), tensile structures are as good as (or better than) rigid ones.

Lockheed Martin is to support Britain's Desert Hawk III unmanned aerial vehicles and establish them as a core defensive capability for the country's military.

Desert Hawk III is a small drone from the company's Skinks Work team and was used by British Army forces in Afghanistan for enhanced situational awareness, security and counter-IED operations, threat detection, route reconnaissance and battle damage assessment.

"Desert Hawk has served the U.K. military well in providing intelligence, reconnaissance and surveillance to tactical warfighters," said Jay McConville, Lockheed Martin director of business development for Unmanned Solutions. "We look forward to continuing this record of success through the award of the Desert Hawk Core Support Program, and we continue to enhance its capabilities based on user feedback.

"Desert Hawk's maturity and proven performance, as well as the enhanced capabilities now available, make it a crucial asset on the modern battlefield."

Desert Hawk III is battery powered, weighs 8 pounds and can fly for 90 minutes with a 2-pound payload.

Lockheed Martin recently upgraded Desert Hawk III through longer endurance, updated sensor payloads and operation using the company's mobile ground control system.

"Desert Hawk has proved its worth on operations in Afghanistan, providing our armed forces with vital intelligence and allowing our commanders to stay one step ahead of the enemy," said Defense Secretary Philip Dunne.

"We recognize that unmanned and remotely piloted air systems are increasingly important in today's operational environment, and our protected Defense budget and �Pounds 160 billion (about $248 billion) investment in equipment has allowed us to bring Desert Hawk into our core program."

Lockheed Martin did not disclose the value of the Ministry of Defense contract.

6:15-10:45 kaveri kertoo RQ-11 Raven minilennokista USMC käytössä.

Muutamia huomioita jotka koskevat varmasti suurinta osaa tuon kokoluokan laitteita
-Kantamat jolta operoidaan on lyhyitä vaikka maksimit voivat olla kohtuullisia
-Pidemmän kantaman mahdollistamat viestiyhteydet saattavat olla hankalia käyttää
-Sensorit eivät välttämättä sovellu tarkkaan paikanmääritykseen. Tärinä ja sääolot aiheittaa virhettä sensorin suunnanmääritykseen jolloin kohteen sijaintia ei voida automaattisesti määrittää.

Raven on pienempi kuin PVn Orbiter IIB, mutta kuitenkin samaa kokoluokkaa ja samat tekijät todennäköisesti vaikuttaa operointiin.

Over the course of the ongoing wars in Iraq and Afghanistan, roadside Improvised Explosive Devices have become the scourge of the United States military’s ordinance disposal units. The IED is a staple weapon of asymmetric warfare tactics, providing an inexpensive, easy to build and difficult to detect weapon capable of inflicting painful losses on a technologically and numerically superior enemy. With the evolution and proliferation of drone technology, ordnance disposal units are now facing a new and worrisome threat, the Flying IED.

This situation was brought to the forefront when a small drone crashed into a tree on the South Lawn of the White House in January. A radar system designed to detect flying objects such as airplanes, missiles and larger military drones failed to pick up the small two foot diameter quadcopter drone as it entered the restricted area around the White House. The drone was operated by a government employee for recreational purposes and was not deemed a threat to the First Family but the event drew the attention of military planners and IED disposal specialists.


If the White House radar system could not detect this small device, it is unlikely military radar systems protecting military installations would detect a weaponized drone. Even though the White House incident was declared an accident and not a threatening situation, military officials are concerned by the possibility that civilian and military targets could be vulnerable to drone attacks. The U.S. Central Command announced recently that it had attacked a remotely piloted aircraft described as a model planes in the possession of operatives for the Islamic State as it was being loaded into the trunk of a car. How operatives planned to use this miniature aircraft is unknown but it is speculated that its use was either for surveillance or as a weapon.

“I personally believe that the unmanned platform is going to be one of the most important weapons of our age,” Navy Capt. Vincent Martinez, commander of the Navy Surface Warfare Center (NSWC) EOD Technology Division, said. “I’m going to have to start thinking about not only how to diffuse the payload but how I defuse the platform. When I walk up on that platform, is it watching me, is it sensing me, is it waiting for me?”

The market for military drones is expected to almost double by 2024 to beyond $10 billion (8.9 billion euros), according to a report published Friday by specialist defence publication IHS Jane's Intelligence Review.

"The global defence and security market for Unmanned Aerial Vehicles (UAVs) will expand at 5.5 percent per year over this decade, from the current figure of $6.4 billion," according to the analysis.

"Unmanned systems are here to stay," said Derrick Maple, principal analyst on unmanned systems for the London-based group.

"These systems are well established, combat proven and are an essential and expanding element of future operations across the globe."

Israel was the top exporter of UAVs last year, but is set to be overtaken by the United States through sales of General Atomics Predator series and Northrop Grumman Global Hawk, said the report.

Western Europe is forecast to reach $1.3 billion in sales by 2024 as it seeks to reduce its reliance on US and Israeli imports, it added.

However, it also faces competition from China, Russia, India, South Korea and Japan -- whose combined sales are predicted to reach $3.4 billion by 2024.

The market is being driven by demand for new technology and different ways of using UAVs, according to Jane's.

"Operators are now moving to expand their mission sets beyond visual surveillance and reconnaissance, and are introducing sophisticated intelligence and electronic warfare systems, as well as a wider range of munitions," said Huw Williams, unmanned systems editor for IHS Jane's.

"As technology matures, we are set to see Unmanned Combat Air Vehicles (UCAVs) come in to service," he added.

"These will feature 'stealthy' characteristics and advanced payloads and weaponry. They will operate alongside manned aircraft and eventually even replace them in many roles."

Drones were used extensively by the US military during its operations in Afghanistan, but have since been increasingly used in civil applications.

MQ-9 Reapereille irtosi myyntilupa Espanjaan.
4kpl, huoltoa, logistiikkaa ja koulutusta yht. 243 miljoonaa dollaria.
Ei aiota edes aseistaa. Pelkkä ISR-alusta. Käyttö homeland, rauhanturvaus, counterinsurgency ja counter-terrorism.

http://www.defensenews.com/story/de...q9-reaper-drone-unmanned-system-buy/73470488/

Todella tyyristä on edelleen. Ei liene meillä varaa hankkia puolen F-35:n hintaista ISR-alustaa, joka ei muuta tekisi kuin liihottelisi vuorokauden kerrallaan vakoilemassa. Hollannilla on tosin sama 4kpl MQ-9:aa aseistamattomana tulossa 16-17 käyttöön.

Brimstonea ja JDAMia muiden muassa pystyisi käyttämään, joten sinänsä ihan mielenkiintoinen vehje.
