GPS plays role in black hole image

Headshot: Tracy Cozzens

Tracy Cozzens

On April 10, the world looked in awe at the first image of a black hole. The image was captured by a world-spanning network of radio telescopes that together, using Orolia atomic-clock technology, create the Event Horizon Telescope.

It zeroed in on the supermassive monster — 6.5 billion times the mass of the sun — in Galaxy M87 to create the image.

As Innovation Editor Richard Langley explains, the technique used to capture the image — very long baseline interferometry (VLBI) — relies on GPS. (VLBI was the topic of Langley’s Ph.D. thesis.)

VLBI links two or more radio telescopes that can be many kilometers apart, or even on different continents. VLBI is used in both geodesy and astronomy. There is also a practical GPS link to the Event Horizon Telescope. From the second of six simultaneously published open-access papers on the result: “All timing is locked to a 10-MHz [hydrogen] maser reference and synchronized with a pulse-per-second (PPS) Global Positioning System (GPS) signal…”

“[T]he long-term drift of the maser [is] compared to GPS, measured by differencing [and plotting] the 1 PPS ticks from the maser and local GPS receiver. The vertical width of the trace is due to variable ionospheric and tropospheric delays of the GPS signal, while the long-term trend represents the frequency error of the maser. The drift measured from this plot, and its effects on the fringe visibility, are removed during VLBI correlation.”

From the third paper: “In order to reconstruct the brightness distribution of an observed source, VLBI requires cross-correlation between the individual signals recorded independently at each station, brought to a common time reference using local atomic clocks paired with the Global Positioning System (GPS) for coarse synchronization.”

Quantum magnetometer senses its place

Scientists continue to search for new technologies to serve the PNT mission. One novel way to augment GPS comes from a newly developed technology involving a quantum magnetometer.

Researchers at Lockheed Martin call it Dark Ice; it uses magnetic sensing as an alternative means of determining location without use of satellite signals.

Mike DiMario and his team have developed a prototype magnetometer that uses a synthetic diamond the size of a salt crystal to measure the direction and strength of nearly imperceptible magnetic field anomalies. They overlay that data with maps of Earth’s magnetic field, supplied by the National Oceanic and Atmospheric Association, to produce precise location information.

Special quantum-level impurities in the molecular structure of the diamond, where intermittently a carbon atom drops out and its neighbor is a nitrogen atom, enable the detection of magnetic field waves. These nitrogen vacancy (NV) centers are hyper-sensitive magnetic sensors. When illuminated by a laser, the diamond emits more or less light depending on the surrounding magnetic field’s strength.

Position + Direction. Dark Ice differs from current magnetic sensors aboard ships and planes in that it can measure both the field strength and the direction the field is pointing. “The real advantage of this quantum-based technology is its ability to produce a true magnetic field vector, while at the same time having a very large dynamic range and bandwidth,” DiMario explained.

Project development “was like peeling an onion: with each new layer removed, the team advanced. We had no idea of the expected outcome, other than what system modeling, the laws of physics and good engineering could predict. There was always something we could not have predicted or even thought of.”

In addition to developing this navigational capability, the team has also demonstrated that Dark Ice can harness Earth’s magnetic field to transmit communications across barriers intended to block all traditional signals, and track moving vehicles in real time.

Unjammable. “This project was designed for times when extenuating circumstances might prohibit your use of traditional GPS signals, and you need something that is unjammable, passive and always available. The Earth’s magnetic field meets this description if we can adequately sense and make use of it,” DiMario said.

He wants to downsize Dark Ice to hockey-puck size for convenient use on multiple platforms. “In real-world conditions, if I can get within 200 meters of GPS accuracy, that would be a huge success,” he claimed. Such precision would serve as a backup or verification to GPS, not a sole-means navigation system.

With its powerful sensing capabilities and small size, Dark Ice could function as the most reliable way to do things like identify hard-to-find watercraft in search-and-rescue missions and fly aboard aircraft in the battlefield. Navigation, search and communications — all in one compact sensor.

The precision-guided projectiles demonstrated various short-, mid- and long-range capabilities.

Besides satellite navigation, Raytheon’s precision weapon systems incorporate laser guidance, high-definition radars, advanced seekers and other technologies.

Designed to be fired from the Navy’s five-inch guns, Excalibur N5 is the sea-based variant of the extended-range, precision munition used by ground forces around the globe. The Excalibur weapon provides accurate, first-round effects at all ranges in all weather conditions.

“Excalibur N5 answers the Navy’s need for a sea-launched, precision-guided projectile,” said Sam Deneke, Raytheon Land Warfare Systems vice president. “N5 doubles the range of the Navy’s big guns and delivers the same accuracy as the land-based version.”

Excalibur is a true precision weapon, impacting at a radial miss distance of less than two meters from the target. Widely used by U.S. and international artillery forces, Excalibur has been fired more than 1,400 times in combat.

The precision-guided projectile was co-developed by Raytheon Company and BAE Systems Bofors.

Besides N5, Raytheon has developed other variants such as the laser-guided Excalibur S, Excalibur HTK and Excalibur Shaped Charged Trajectory.

Orolia SecureSync to synchronize FAA’s enroute radar systems

Orolia, a provider of resilient positioning, navigation and timing (PNT) solutions, announced that its SecureSync time and synchronization servers have been selected to support enroute radar systems across the U.S.

The selection comes as part of the Federal Aviation Administration’s (FAA) move towards a Next Generation Air Transportation System (NextGen). NextGen is about halfway through a multi-year investment and implementation plan.

The FAA plans to keep rolling out NextGen technologies, procedures and policies through 2025/2030 and beyond.

While NextGen will rely heavily upon GNSS to increase capacity, efficiency, and safety in the National Air Space (NAS), many technologies including legacies such as radar will be integrated into the system for maximum robustness to error and disruption.

The FAA employs a variety of radar types for short-, medium- and long-range air traffic control requirements. These diverse radars require different types of timing signals and outputs to suit their operations.

SecureSync. Orolia’s SecureSync provides the necessary timing outputs and signals to meet these requirements. The time server’s ability to provide resilient, accurate and reliable timestamps for the data that it receives from radars is used to quickly organize the data for the aircraft control user interface.

The only time and synchronization device approved by the Defense Information Systems Agency (DISA) for use in U.S. Government networks, Orolia’s SecureSync provides reliability, security and flexibility to synchronize critical aviation operations. SecureSync combines multi-GPS/GNSS signal synchronization, options for alternative signals and BroadShield GPS anti-jamming/spoofing protection for transportation systems. SecureSync combines Orolia’s precision master clock technology and secure network-centric approach with a compact modular hardware design.

The FAA selected Orolia for the competitive program based on its proven timing and synchronization technology and its ability to offer multiple output options as commercial off-the-shelf (COTS) products that do not require additional research and development time or investment.

“Consistently accurate timestamps and the synchronization of thousands of real-time flight data points are essential for safe and efficient enroute air traffic operations,” said Jean-Yves Courtois, CEO of Orolia. “Orolia is proud to support the FAA’s radar data and aircraft control user interface requirements to improve air travel services nationwide.”

More About the SecureSync COTS Product. Built-in time and frequency functions are extended with up to 6 input/output modules. Included with the base unit is a 1PPS timing signal aligned to a 10 MHz frequency signal without any 10 MHz phase discontinuity.

A variety of internal oscillators are available, depending on requirements for holdover and phase noise. On-board clocks synchronize to a variety of external references as standard, factory-installed or upgradable options.

Users may add alternate signals of opportunity to GPS or GNSS input references to improve resilience, or use them for indoor applications and choose from a variety of option cards to add to configuration of timing signals, including additional 1PPS, 10 MHz, time code (IRIG, ASCII, HaveQuick), other frequencies (5 MHz, 2.048 MHz, 1.544 MHz), telecom T1/E1 data rates, multi-network NTP and PTP. Modules can be customized for exact requirements.

To support network time synchronization, SecureSync supports the latest features of network time protocol (NTP) and precision time protocol (PTP, IEEE-1588v2). An optional multi-port NTP configuration allows for operation across 4 isolated LAN segments. Up to 6 PTP ports can be added to operate in various PTP deployments.

SecureSync is a security-hardened network appliance designed to meet rigorous network security standards and best practices. It ensures accurate timing through multiple references, tamper-proof management and extensive logging. Robust network protocols are used to allow for easy but secure configuration.

Features can be enabled or disabled based on network policies. Installation is aided by DHCP (IPv4), AUTOCONF (IPv6), and a front-panel keypad and display. The 1 RU chassis supports multi-GNSS (GPS/ Galileo/GLONASS/BeiDou/QZSS) input.

Options include SAASM, supporting L1/ L2, available for authorized users and required for the US DoD, and BroadShield GPS jamming and spoofing detection. The unit is powered by AC on an IEC60320 connector. DC as back-up, or primary, is available.
