ESA provides new maps of Earth from reflected satnav

News from the European Space Agency

Your phone or satnav receiver routinely picks up signals from navigation satellites in order to tell you precisely where you are. But have you ever thought what happens to those satnav signals afterwards? A foresighted ESA inventor had the idea of using them as a tool for observing the Earth.

More than 120 satellite navigation satellites are in orbit, making up multiple constellations including Europe’s Galileo system, sending down a continuous rain of satnav signals for the benefit of users worldwide. Just like visible light, these microwave signals go on to reflect off Earth’s land and sea surfaces.

The traditional attitude to these reflected signals is to see them as something of a nuisance — known as multipath, they can confuse satnav receivers and reduce their overall accuracy.

But back in 1993 — at the same time as the US GPS satnav system reached its full constellation of 24 satellites — a young ESA microwave engineer called Manuel Martín-Neira came up with the idea of treating these satnav reflections as a scientific resource instead.

“My head of division asked me to come up with a budget-friendly way of increasing the overall sampling rate to build up a fuller picture of mesoscale phenomena, and that led me to start looking into making use of additional signals of opportunity, chiefly satnav signals.

“The initial reaction was mixed, because the forecast accuracy was not as precise as the ERS-1 altimeter could deliver — but on the plus side there would be a lot of these signals to make use of, and the performance has improved a lot since those early days.”

Inspiration from reflection

The basic idea of what Manuel christened the Passive Reflectometry and Interferometry System, or PARIS, comes down to a two-sided antenna. As the topmost side picks up a satnav signal from the satellites in orbit, the other side picks up the version of the signal bounced back from Earth.

By comparing this initial, overhead signal with its reflected equivalent using a process called interferometry — measuring tiny differences in signal phases – the extra travel time of this reflected beam can be determined, down to an accuracy of less than five centimetres, determining sea height and sea ice thickness.

Additional amplitude waveform processing can deliver further data on wind and wave measurements over the ocean, and soil moisture and biomass over land.

Satellite reflectometry has since grown into a thriving field. This summer, Manuel attended the latest international workshop on the method he first devised 26 years ago.

Reflectometry reaches space

“It’s been fantastic to have experimental evidence, and that’s really been made possible by the growing availability of smaller satellites,” explains Manuel.

“Because satellite reflectometry is a passive form of remote sensing, it makes for an attractive potential payload because it doesn’t need a lot of power to operate. Then one of the results is meteorology data that private companies intend to make money with by delivering to public agencies.”

In 2003, the UK-DMC satellite was the first mission to fly a reflectometry payload, followed in recent years by, for example, the UK’s TechDemoSat-1, NASA’s CyGNSS constellation to monitor hurricanes and the Spire global constellation of commercial nanosatellites.

“These satellites have really given the reflectometry community a wealth of signals, demonstrating what reflections look like over different surfaces including sea ice, forests, and even inland water bodies such as the Amazon River and its tributaries.

“In parts of the ocean near continental masses and within atolls we are seeing reflected signals from very calm waters which resembled a mirror, giving us very high precision down to 1 cm level. Such measurements could potentially complement current altimetry missions, by for instance measuring sea level rise.”

ESA activities taking flight

ESA meanwhile is active on reflectometry in various ways, having developed and tested a steerable airborne antenna called the Software PARIS Interferometric Receiver or SPIR, capable of steering separate antenna beams to build up a rapid surface picture, and differentiating between different signal sources, such as GPS from Galileo.

Manuel adds: “ESA’s GNSS Science Support Centre, based at the Agency’s European Space Astronomy Centre near Madrid, has been taking a keen interest in these activities.”

Missions are also in development, including a dedicated CubeSat with RUAG-Austria and the University of Graz called PRETTY (for Passive REflecTomeTry and dosimetry, which would also carry a radiation detector), and a small satellite pair called FSSCat from Spain’s Universitat Politècnica de Catalunya, backed through the Copernicus Masters competition, seen as a prototype for a future reflectometry constellation.

ESA’s Directorate of Telecommunications and Integrated Applications is also working with the Spire company to fly enhanced reflectometry instruments, starting at the end of this year.

When it comes to the thriving state of today’s reflectometry community, Manuel recalls the patenting of his idea as a turning point: ‘Having had this idea, which was not particularly well received, the proposal by ESA’s Patents Group to patent it made all the difference. It gave me a feeling of confidence, that somebody else at least saw the potential of this idea — and the rest is history.”

The defense segment is going from strength to strength — despite a phase not too long ago when defense spending appeared to be dropping. Widespread drone use received a boost with specialized equipment developed for defense forces applications.

The Predator Advances

The General Atomics Predator has gone from a long-distance loiter-and-observe UAV to frontline precision-strike capability, and has been adopted by many military forces around the world.

From first flights in 1994 to initial production in 1997, the Predator has now evolved into many configurations equipped with piston engine, turboprop and jet; line-of-sight radio and satellite command and control; synthetic aperture radar and multi-spectral targeting system; video, TV and thermographic cameras; and laser designators and other payloads.

From pure reconnaissance to various strike and attack configurations, the names have also changed. Predator, Reaper, Gray Eagle, Avenger, Protector, Guardian and SkyGuardian have a host of RQ/MQ designations. For instance, In the RQ-4 Global Hawk name, the “R” means reconnaissance, the “Q” means unmanned aircraft, and the “4” is the series.

The SkyGuardian version of the Predator is a certifiable variant anticipated to ultimately become fully authorized for controlled airspace. It will take part in the NASA Systems Integration and Operationalization (SOI) demonstration program in mid-2020, which will highlight commercial UAS missions using larger drones in the national airspace.

The Predator family has now been evolving for more than 25 years. Unfortunately, the popularity of the Predator family of military unmanned aircraft has led to recent headline news about Predators shot down in the Gulf of Hormuz, or crashed in Afghanistan — such is the price of success!

Global Hawk Gathers Intel

The Northrop Grumman Global Hawk has become a U.S. mainline, high-altitude intelligence gathering asset, deployed by both the U.S. Air Force (RQ-4 Global Hawk) and Navy (MQ-4C Triton). Other friendly nations have also shown various levels of interest in acquiring variants, including Germany, Australia, Canada, Japan and South Korea.

Northrop Grumman has reintroduced the Firebird as a contender in the airborne intelligence, surveillance and reconnaissance (ISR) field. The Firebird can be configured as unmanned (ground control), autonomous or piloted, and has payload flexibility through open architecture, plug-and-play integration.

The North Dakota UAS test range facility at Grand Sky has initiated procurement of two Firebird UAVs, which they intend to supply to their customers for mapping, inspection and monitoring applications using their extensive, long-range BVLOS capabilities.

Skyborg Equipped with AI

And then there’s this U.S. Air Force Skyborg program, which aims to drag the most possible out of artificial intelligence (AI) and automation in an airborne fighter support roll. Kratos has flown the drone hardware a couple of times – the XQ-58A Valkyrie is a “low-cost” unmanned aircraft designed to fly alongside front-line attack aircraft like the F-35 and F-18.

The Air Force Research Laboratory (AFRL) is researching the technology, new sensors, payloads and networking capability these drones will be outfitted with to fly alongside manned fighter jets.

A whole slew of other extremely capable drones are already being operated by the U.S. Army and Navy in a variety of support roles.

Anti-Drone Detection and Prevention

On the flip side, an entirely new related industry segment has come about in the last several years, usually adapting existing radar, sound, infrared or other ground detection systems.

This segment is aimed at circumventing unwelcome drone encroachment over sensitive facilities. Airports, governments, prisons, and energy and water utilities are among the facilities who want to prevent unwanted drones penetrating their airspace.

Solutions may be portable and short range, or ground-based and longer range, with the capability to take down an invading drone or detect where it came from and provide significant warning time.

One solution uses an attack drone that ensnares an intruder-drone in a net and brings it the defender’s location to support second-level investigations. Whatever the solution, drone defense is a growing field.

Tallysman has released its VSP600L VeroStar precision antenna at Intergeo 2019, which took place Sept. 17-19 in Stuttgart, Germany.

The VeroStar supports the full GNSS spectrum, as well as L-band correction services. The antenna provides low elevation satellite tracking with a high efficiency radiating element, the company said.

It features a light, compact and robust design, in addition to low axial ratios from zenith to horizon. According to Tallysman, the VSP600L VeroStar also provides high receive gain over the full GNSS spectrum from low GNSS band (1164MHz to 1300MHz) L-band correction services (1539MHz to 1559MHz) to high GNSS band (1559MHz to 1610 MHz).

The antenna also boasts a tight phase center variation, low current, invariant performance Fromm m+3 to 16VDC and high gain-to-noise at low elevation angles.



“The most unique feature of the VeroStar antenna is the high gain at low elevations,” Allen Crawford, director of key accounts at Tallysman, told GPS World at the show. “It can track low elevation satellites with a really high signal level, which is really important for those using correction services coming off of geostationary satellites. So as you go further away from the equator, you’re dealing with some very small link margins and you need those extra up to 4dB higher signal strength that this antenna provides.”

According to the company, it will soon be releasing embedded models of the VSP600L VeroStar.

At the show, the company also released an updated line of its helical antennas, including the single frequency HC771, dual frequency (plus L- band corrections) HC882 and the triple band (plus L- band corrections) HC975. The original line of helical antennas, which includes the HC600, HC871 and HC872, were released earlier this year.
