A new technology center from the Israel Ministry of Defense will develop and manufacture GPS-free navigation technology. The ministry's Directorate of Defense Research and Development and Israel Aerospace Industries recently inaugurated the center. (IAI)

Israel’s Ministry of Defense opened a new research center to develop navigation systems that don’t rely on easily disrupted GPS.

As militaries across the world work to provide stronger GPS signals and alternatives, the Advanced Navigation Technology Center, opened with state-owned Israel Aerospace Industries, will manufacture highly accurate inertial sensors.

“These sensors will enable the production of next generation navigation systems, and will significantly increase their performance and capabilities,” a March 10 ministry statement said.

Brig. Gen. Yaniv Rotem, head of research and development at the ministry’s Directorate of Defense Research and Development, said the center will aid Israel’s technological independence.

The goal is to field an independent solution for navigation that can go longer periods of times, through all its missions, without using GPS.

Avi Elisha, general manager for IAI’s division for electro-optical and navigation systems, said the center will use the company’s unique technologies. “Only a handful of countries have this technology, which is a game-changer in the field of inertial navigation.”

Beyond helping in GPS-denied environments, IAI systems and sensors that work without satellites also provide more accurate navigation, offering the measurements of a gyroscope and from sensors that track acceleration and distance traveled, according to Zalman, head of technologies and research and development at IAI’s navigation division. The company did not provide his full name for security reasons.

In contrast, he pointed out that satellites don’t provide physical dimensions, just measures from space. “If there is a rocket launcher or tank or missile, you need to know the azimuth [measurement] to move the turret or elevation of the gun to fire, so navigation gives you the azimuth and roll and the altitude,” he said. “When you fire something, you need navigation regardless of GPS because it gives you altitude to fire a rocket or missile or point the gun to a specific target, so that is the advantage of an inertial system.”

Finlandia prueba que Rusia interfiere los sistemas GPS

Finland to probe reports of Russia disrupting GPS during NATO drill

Finland's GPS signal was disrupted during NATO's recent military drills and Russia may have been the culprit, according to Finland's prime minister. The apparent jamming also affected air traffic in Norway.



Pilots in Finland and Norway lost GPS navigation signals during recent NATO's large-scale Trident Juncture exercise near Russia's western border.

Speaking to Finland's public broadcaster Yle on Sunday, Finnish Prime Minister Juha Sipila said that Moscow was likely to blame for the jamming.

"Technology-wise, it's relatively easy to disturb a radio signal, and it's possible that Russia was behind it," he was quoted as saying.



Sipila is known for often piloting his private jet himself for official trips

"We will investigate, and then we will respond," he added. "This is not a joke, it threatened the air security of ordinary people."

The 57-year-old Sipila, who is also an experienced pilot, said that the incident would be treated as a breach of Finnish airspace.

The goal of the alleged Russian interference was "to demonstrate the capabilities for such actions," he said.

Looking across the border

The disturbance targeted the Finnish region of Lapland and parts of Norway near the border with Russia.

The regional Wideroe airline confirmed its pilots had experienced GPS disruptions. But it said that pilots aboard civilian planes have several contingency systems to fall back when a GPS signal is lost.

Sipila's comment came four days after NATO forces ended their two-week Trident Juncture exercise. Operations took place in Norway, parts of Finland and Sweden, the North Atlantic and the Baltic Sea and involved some 50,000 participants.

Despite Finland not being a NATO member, soldiers from the Scandinavian country also took part in the drill, a decision that angered Moscow. Finland shares a 1,340 kilometer (833-mile) border with Russia.

Last week, Norwegian media outlet Barents Observerreported on the loss of GPS signals in parts of Norway's airspace. The Oslo authorities have already accused Russia of disrupting the navigation system during Russia's Zapad-2017 drills.

Nuevos equipos de navegación para las fuerzas australianas

Upgrade to Australian Defence Force Navigation Warfare Capability



JP 5408 aims to provide Global Positioning System (GPS) Navigation Warfare (NAVWAR) protection to selected legacy ADF platforms and land forces.

Minister for Defence David Johnston today announced Government approval of a critical project to upgrade and enhance the protected Global Positioning System (GPS) capability of the Australian Defence Force.

“The Government recognises that to ensure the ADF remains viable and robust we need to invest in force protection, countermeasures, protective security, system redundancy, lower signatures and stealth for our capabilities and systems,” Senator Johnston said.

GPS plays a vital role in providing accurate positioning, navigation, coordination, and targeting for the ADF and the ability to use modern GPS equipment is fundamental to operational effectiveness.

Senator Johnston said GPS jamming equipment has become easier to produce and deploy, and the ADF needed to continue to meet this evolving threat. JP 5408 Phase 3 (Platforms) Tranche 2 will enhance GPS on a range of ADF platforms by providing either protection or redundancy capabilities in response to GPS denial activities.

The total value of this project is in the order of $30 million.

Platforms to be upgraded include:

- Collins Class Submarines
- Hydrographic Survey Ships
- Survey Motor Launches
- Provision of Alignment Kits for Ground Based Air Defence systems
- Special Forces Rigid Hull Inflatable Boats
- Mine Hunter Coastal Ships.

“This project will strengthen the ADF’s ability to operate in a GPS denied environment and will increase the operational capability and safety of Australian service personnel.”

Senator Johnston said the project will include opportunities for Australian Industry partners to assist in the integration and maintenance of the protected GPS capability acquired under the project.

¿Hacia un GPS Arg?

La Fuerza Aérea proveerá un sistema GPS nacional 

Mantenido en reserva, se lleva a cabo con la colaboración de otros organismos como INVAP, CITEDEF, CONAE y el IUA. Asegurará las operaciones aéreas y brindará un sistema GPS, fundamental para la navegación aérea, naval y terrestre. 

 

La Fuerza Aérea realizó un proyecto que asegurará las operaciones aéreas y proveerá de un sistema GPS nacional, fundamental para la navegación aérea, naval y terrestre. Se llevó adelante con la colaboración de otros organismos como INVAP, CITEDEF, CONAE y el IUA. 

Este mecanismo mejorará las comunicaciones de las FFAA que hoy se encuentran saturadas, certificará las operaciones aéreas, así como también servirá de sistema de guía para armamento stand-off. El sistema consiste en la integración de diversos proyectos que están llevando a cabo los organismos y que se dividen en apariencia en tres niveles de acuerdo a la altura en que se encuentren. En el nivel más alto, la estratósfera, estará compuesto por una constelación de microsatélites de uso militar que se denomina Proyecto Antares. 

En un nivel más bajo, en órbita baja, estará una serie de UAV de gran tamaño que realizarán vuelos estacionarios, con el propósito de realizar reconocimiento y exploración. El UAV, de grandes dimensiones, cuenta con una envergadura alar de 90 mts y es capaz de tener una autonomía de seis meses en vuelo estacionario. Este proyecto se denomina Proyecto VENO (Vehiculo Espacial No Orbital). 

En la atmósfera completan el sistema diversos aviones con diferentes equipamientos como COMMINT, ELINT y radares de alerta temprana. Mientras que en la tierra, habrá radares fijos 3D y móviles.

Francia utiliza bombas de hormigón contra los tanques de Gadafi

La aviación francesa está recurriendo a bombas de práctica rellenas de concreto para destruir a tanques y otros blindados del ejército del dictador libio Muammar Gadafi.

Así lo confirmó el coronel Thierry Burkhard, portavoz del Estado Mayor francés, quien señaló que estas armas de 300 kg. (600 libras) se utilizaron por primera vez el 26 de abril, para destruir (en realidad, el término utilizado fue “aplastar”) a un blindado de Gadafi en las cercanías de la ciudad de Misrata.

La idea de utilizar estas bombas surgió de la necesidad de encontrar un arma que sirviera para dejar fuera de combate a un vehículo blindado sin que se generen explosiones, incendios o esquirlas que pudieran afectar a civiles en las cercanías (los famosos y lamentables “daños colaterales”)

Los proyectiles igualmente están guiados por láser o GPS que aseguran su precisión, y pueden viajar a una velocidad de 300 metros por segundo. La combinación de peso y velocidad parece ser suficiente para destrozar o inutilizar a un blindado sin que el mismo estalle.

Este tipo de armas resulta más útil en este momento del conflicto, cuando las tropas de Gadafi ocultan sus vehículos y artillería en medio de zonas edificadas, en las que se pueden hallar varios no combatientes.
