  Israel Plans Anti-Missile Nano Satellite Constellation

  By ARIE EGOZI TEL AVIV: Israel is planning constellations of nano satellites, built by Israel Aerospace Industries (IAI), that will allow almost continuous coverage of “areas of interest,” which are likely to include Iran, Syria, Lebanon and other countries, according to experts that are not connected in any way to the program. IAI refused to comment. The first nano satellite was developed by IAI and was launched into space in 2017 as part of a scientific experiment. The 5-kilogram satellite — approximately the size of a milk carton — is equipped with special cameras able to identify various climatic phenomena, and a monitoring system that allows the choice of areas to be imaged and researched. ”We are developing the capability to launch a constellation of Nano satellites. The large number of satellites will give us the capability for a much higher rate of revisits, and actually a continuous monitoring of areas of interest.” says Opher Doron, general manager of IAI's Space Division. The nano satellites optical payloads are smaller and the quality of their optical payloads is lower. ”But by using a temporal resolution method this problem is dealt with in a very effective way,” Doron claims. “This method is not directly related to the quality of the sensor but is based on the frequency of revisits over a site.“ The other problem with smaller satellites is color. “Resolution is, of course, very important but we also work on improving the color quality of the images, Doron said. “A good intelligence expert does not need color to extract, the needed intelligence from a satellite image, but when it comes to decision-makers, color is of great importance.” What underpins all this? It takes a ballistic missile 12 to 15 minutes to travel from Iran to Israel. The earlier a launch is detected and the earlier the trajectory of the missile can be plotted, the better the chances to intercept it far from its designated target. Today, low orbit Ofeq spy satellites visit “areas of interest” in wide intervals so their optical or radar payloads cannot keep a persistent watch. When it comes to the ballistic missile threat, this is a major problem. Israeli sources say that some 30 minutes are needed from the command to prepare a ballistic missile for launch until it is ready for launch, and this if the protection silos are well equipped. If the enemy is aware of the “visiting” time of the spy satellites over his territory this can be the perfect time to avoid detection of the preparations until the launch itself. Once launch occurs, Israel is supposed to get warnings from Lockheed Martin's Space-Based Infrared System (SBIRS),the US constellation of geosynchronous earth orbit (GEO) satellites. The U.S also deploys an X-band radar system in southern Israel to improve detection of ballistic missiles. This complements the layer supplied by the Green Pine radar, part of the Israeli Arrow missile interceptors. The first nano satellite was launched from India on the PSLV-C37 launcher with 103 other nano satellites. The plan to build and launch nano satellites first emerged a decade ago. A joint company of IAI and Rafael would undertake the mission. But that plan was deserted. Yizhak Ben Israel, chairman of the Israeli space agency, served in the Israeli air force and later was in charge of developing Israel's most advanced and classified military systems at the development directorate in the Defense Ministry. He notes that, although nanosats possess much less exquisite capabilities than SBIRS or other large satellites, “when you use a constellation of such satellites the combined capability can be very effective in missions like locating missile launchers.” The other advantage of nano satellites is their price: “You go from hundreds of million of dollars for a full size imaging satellite to some millions of dollars when it comes to a nano satellite.” Not directly related to the nano satellite program but part of Israel's space effort, IAI teamed with British start-up company Effective Space to make a fleet of special satellites weighing roughly 880 pounds that can refuel other satellites in space. IAI signed an agreement for technological and financial cooperation with the smaller company. While Effective Space is headquartered in London, its CEO, Arie Halsband, was general manager of IAI's space division before starting his own company. https://breakingdefense.com/2018/10/israel-plans-anti-missile-nano-satellite-constellation

  Kratos Targets Ground System ‘Revolution’

  We think that p-LEO is a big deal. And there's got to be a revolution that has to hit the ground segment, says Phil Carrai, president of Kratos's space, training and cyber division. By THERESA HITCHENSon August 17, 2020 at 1:20 PM WASHINGTON: As DoD and commercial industry scramble to develop small satellite constellations in Low Earth Orbit for everything from high-speed communications to near-real time Earth observation, Kratos is quietly working to solidify a central role providing the new ground systems required to make them work. While there is enormous military and commercial interest in the proliferation of small LEO satellites, known as p-LEO, not nearly as much attention has been paid to the radically different ground-based infrastructure to support those constellations. But the necessary changes in ground architecture will be monumental, and extremely lucrative for those companies at the crest of that wave. “We think that p-LEO is a big deal. And there's got to be a revolution that has to hit the ground segment,” says Phil Carrai, president of Kratos' space, training and cyber division. “We think this is kind of our play for the next many years. ... We've been making some substantial investments in that, in the sense of taking what was analog and stovepiped and moving it into a digital, dynamic, cloud infrastructure.” Kratos, headquartered in San Diego, is a mid-tier company with $750- to $800 million in annual revenue, and is perhaps best known in the defense arena right now for its low-cost attritable drones. Its XQ-58A Valkyrie is one of the top contenders for the Air Force's high-profile Skyborg program to build autonomous drones that can mate with piloted aircraft for a variety of missions; it also is providing an airframe, based on its Mako UTAP-22, as a subcontractor to Dynetics in DARPA's Gremlins program to develop drone swarms. But space-related work is the firm's bread and butter. Kratos' space, training and cyber Division is the company's biggest, Carrai said, with a large, but often behind-the-scenes, footprint in both the military and commercial satellite communications markets. Indeed, while Valkyrie's role in the Air Force's Advanced Battle Management System (ABMS), which is developing new technologies to support command and control of future all-domain operations, has been well documented, Kratos space-related comms systems and ground equipment are actually playing a bigger part as subsystems within many other company's offerings, company officials explained in a teleconference with Breaking D. “Our space portfolio really is all about communications and the ground segment, if you will, so that's been our heritage,” Carrai said. “Probably 90 percent of US satellite missions use our technology in one form or fashion. So, we are rather unique in the sense that we can claim the US Air Force and SMC [Space and Missile Systems Center] as one of our largest customers, and, probably in our top 10 or top five, Intelsat and SES are also very large customers.” The advent of 5G mobile telecommunications networks, and its promise of hyper-connectivity through the Internet of Things including from space, has mesmerized DoD and the Intelligence Community, as well as industry. The chief benefit of tying together satcom and wireless and terrestrial networks, for both national security and commercial communications, is expanded reach to hard-to-access areas. For example, satellite signals have trouble penetrating areas like ‘urban canyons'; laying fiber and erecting cell-towers in rural and harsh terrain such as mountainous regions is very costly if not impossible, but satellite communications is relatively simple. The challenge is integrating currently incompatible (in more ways than one) and heavily stovepiped networks in a seamless fashion that allows near-instantaneous roaming among them. That is why the ground system issue is so important. “We think that there's a substantial change that needs to take place from the ground perspective,” Carrai said. Not only will there need to be “way more sites” to connect to fast-moving LEO satellites due to the simple laws of physics, but satellite ground stations will need to be configured more like terrestrial communications nodes with machine-to-machine operations ensuring the best link to any one satellite at a given place or time. Chris Badgett, Kratos VP for Technology, explained that this kind of “dynamic resource allocation or that dynamic situational awareness” is particularly important to military users in order to provide jam-proof communications. In essence, this would allow a military radio to ‘jump' from one frequency being jammed to another that is open. Today, if ‘changing the channel' is possible, it is up to a solider or sailor or Marine to figure that out and manually flip switches. The ultimate goal is to automate that frequency and network ‘hopping' capability so that users don't even notice that it's being done. The mess that is the world of DoD satcom terminals is a long-standing sore-thumb for operators, particularly in the Army. As Breaking D readers know, DoD currently maintains 17,000 terminals with “approximately 135 different designs,” as the Government Accountability office found. Those terminals operate across diverse platforms—such as ships, backpacks, vehicles and aircraft — all with differing system requirements, so that for the most part each terminal system (i.e. each type of radio) is tied to only one satellite network and one type of platform. And while fixing the current problem is already a Herculean task, it could be a show-stopper to Dod's vision of future all-domain operations, linking sensors and shooters provided by all the services together via a Joint All-Domain Command and Control (JADC2) network. “The major obstacle that we have from a ground system standpoint is the current ground architectures have all been designed and developed in a very stove-piped and mission-specific sense. And so each ground system was designed for the mission that it was supporting,” said Frank Backes, senior VP for Kratos Space Federal Solutions. “Where we're going now with a joint, or combined, capability is the integration of those ground systems. And therein lies the complexity. “How do you take a legacy-based architecture that was very stovepipe designed and integrate it together into a common system that gives you enterprise-wide control of the infrastructure, and also gives you the awareness of all the systems? It's very easy to become overwhelmed in the information that a combined system provides,” Backe added. As Breaking D readers know, sorting out those answers is what Gen. Jay Raymond, head of the Space Force, set out to do with his Vision for Enterprise Satellite Communications (SATCOM). That is aimed at creating a seamless network of military and commercial communications satellites in all orbits, accessible to troops, vehicles, ships and aircraft via ground terminals and mobile receivers that would automatically “hop” from one satellite network to another. Carrai said Kratos believes that ultimately the “current analog stovepipe infrastructure that exists today” must simply be replaced. What is needed for integrated satcom is “a roaming modem or a roaming terminal,” and the ability to integrate satellite-provided imagery into the network, a “kind of a virtual antenna.” “If you don't have that capability, you're not going to be resilient, it's going to cost a lot of money, and you're going to create a huge exposure because everybody's going to know what antennas are used for what purpose,” he added. All that said, Carrai opined that partly because of push from the Space Force, the stovepipe problem with milsatcom networks is beginning to change. “It's still a struggle,” he said, because “there's a lot of drive from the spacecraft manufacturers to link the ground system with it. You know, that's what makes it a multibillion dollar system.” In addition, he said, the scramble by commercial satcom operators to get on the 5G bandwagon is forcing them to figure out how to open up proprietary networks. “Commercial operators all see that 5G and data is their future, not broadcast, he said. “The commercial operators are going to lead if not the defense side because they have to interoperate with the telecom operators if they're going to survive.” https://breakingdefense.com/2020/08/kratos-targets-ground-system-revolution

  FRENCH ARMED FORCES BOOST THEIR SECURE, HIGH-THROUGHPUT SATCOM CAPABILITIES WITH THALES TECHNOLOGIES

  The French defence procurement agency (DGA) has awarded Thales a major contract to design and build the ground segment for the next-generation Syracuse 4 satellite communication system for the French armed forces. From 2023, the armed forces will benefit from interoperable communication capabilities with improved throughput, availability, threat protection and end-to-end connectivity. This contract will enable French armed forces to meet their initial strategic capability objectives for the Scorpion vehicle programme, the Charles De Gaulle aircraft carrier and the Rafale combat aircraft. An instrument of national power, space is strategically important for the defence authorities: military satellite capabilities enable forces to operate independently, with greater precision and with the highest levels of security. With the development of expeditionary missions and a growing operational need for advanced in-theatre communications, commanders and deployed forces on the move must be able to access and share information quickly. For urgent interventions and broader operations, forces need end-to-end, high-throughput mobile communication systems that are protected and secure with 24/7 operation and a high level of availability. Syracuse 4 will benefit from Thales's expertise in satellite communication systems, which the company has built up as a technology orchestrator and integrator in France and internationally. It will rely on the System21 highly secure transmission system to guarantee the availability and confidentiality of all communications and protection against jamming, interference, interception, detection and cyberattacks. As Thales Alenia Space will participate in the design of the ground segment, it will be responsible for the management of the mission and will enable the consistency of this kind of management in the frame of the onboard and ground contract for Syracuse 4 program. As prime contractor for the Syracuse 3 ground segment since 2004, Thales has deployed over 1,000 satcom stations worldwide and is a NATO approved supplier with its System21 protected and secure transmission system. https://www.thalesgroup.com/en/group/press-release/french-armed-forces-boost-their-secure-high-throughput-satcom-capabilities
