SSTL demonstrates new GNSS-R capabilities

The successful demo consolidates concept designs for a proposed land-sensing ESA Scout mission, HydroGNSS

Surrey Satellite Technology Ltd. (SSTL) has successfully demonstrated GNSS reflectometry (GNSS-R) from its 18-kg DoT-1 satellite. SSTL has pioneered the new field of GNSS-R with successful payloads on board TechDemoSat-1 and the CYGNSS constellation, and is continuing to develop the technology and data analysis in pursuit of this new science.

The GNSS-R payload onboard the DoT-1 satellite is incorporated within a new small-form-factor Core Avionics module integral to all SSTL’s future satellite platforms. This innovation paves the way for any SSTL satellite that can accommodate a nadir pointing antenna to become part of a GNSS-R small-sat constellation.

GNSS reflectometry is an Earth-observation technique that uses GNSS signals as L-band radar sources, allowing the satellite to take measurements of ocean wind speeds, polar ice and hydrological land parameters, at a higher spatial resolution and an order of magnitude lower cost than other methods.

“GNSS-R is a powerful new science that can contribute valuable data to help monitor changes in our global climate, and I am really pleased with the success of our DoT-1 demonstration.,” said Phil Brownnett, managing director of SSTL. “We now have an advanced instrument design and deep expertise in this new field, and I am hopeful that SSTL’s HydroGNSS concept will progress to a full mission to support the global climate-control challenge.”

HydroGNSS mission

The GNSS-R technology demonstration from SSTL’s DoT-1 satellite is also an important stepping stone for a proposed European Space Agency (ESA) Scout Mission Concept called HydroGNSS, which comprises two 40-kg satellites that collect data continually in near-polar orbits, taking hydrological measurements over the whole globe.

The HydroGNSS mission concept makes advanced use of new GNSS reflectometry techniques such as Galileo signals, dual polarization, and coherent signal acquisition to measure four Essential Climate Variables (ECVs) over land: soil moisture, inundation, permafrost freeze/thaw, and biomass. HydroGNSS has been down-selected by ESA for a concept study; the finally selected Scout mission will commence in 2021.

The below animated video illustrates the HydroGNSS mission.

SSTL’s GNSS-R instrument collects and processes measurements into a “delay Doppler map” (DDM) that can be corrected and inverted into Level 2 products such as ocean wind speed, as has already been successfully demonstrated by the SSTL GNSS-R instruments onboard the TechDemoSat-1 and CYGNSS missions.

The plot below shows results from data gathered by the DoT-1 satellite on Aug. 12, and shows simultaneous DDMs from four separate GPS satellites. As this is a forward scattering technique, the stronger signals with redder peaks indicate a calmer ocean with lower wind speeds. Approximately 40 minutes of data were collected from the Pacific to the Antarctic to the Southern Ocean.

Soil moisture measurements

Data from the SSTL GNSS-R instruments onboard the CYGNSS mission have demonstrated the potential for soil moisture measurement by GNSS reflectometry, and preliminary work shows that GNSS-R also has good sensitivity for freeze/thaw sensing in the active zone of permafrost. Unseasonal changes in the permafrost cycles could potentially release larger quantities of methane, which risks exacerbating global climate change.

GNSS-R can also be used to assess biomass, a measure of forest density which acts as a vital sink for removing carbon dioxide from the atmosphere. In addition to longer term climate observations, soil moisture and inundation measurements from GNSS reflectometry can provide important information for short-term operational purposes, for example, towards Numerical Weather Prediction and flood warnings following rainfall events.

The development of SSTL’s new GNSS-R instrument was funded in part by the European Space Agency.

New US Army PNT office welcomes industry on GPS-denied solutions

The U.S. Army is opening a new office and laboratory to develop agile position, navigation and timing solutions to reduce soldiers’ dependence on GPS, according to reports in C4ISRNET and Defense News.

The new PNT modernization product office will focus on developing and deploying solutions that keep soldiers operating in areas where the GPS signal has been denied, degraded or spoofed. The office will open Oct. 8, and will use an open-systems architecture.

The new office will also host an Open Innovation Lab, a space where commercial entities can work with the Army to develop PNT solutions. Within lab, the Army has set aside space for the CMOSS (C4ISR/EW Modular Open Suite of Standards) Lab and the Network Cross-Functional Team’s Orion Forge at Aberdeen Proving Ground in Maryland.

The lab will be physically separated from the more classified areas of the site to encourage engagement with industry. Technologies to be explored include radio frequency systems, GPS, alt-nav, chip-scale atomic clocks, other timing technologies and celestial navigation.

According to the reports, the technologies will be fielded fast, with new solutions every five years. This is in contrast to the usual method of a decade spent developing technologies meant to last 20 years so that soldiers can always combat adversaries’ capabilities.

UK hits reset on how to deliver satnav

The United Kingdom will explore new options for satellite navigation and timing capability to support critical infrastructure, it announced in a press release.

The Space-Based Positioning Navigation and Timing Programme (SBPP) will explore new and alternative ways to deliver vital satellite navigation services to the U.K. for transport systems, energy networks, mobile communications, and national security and defense.

The SBPP also aims to boost the British space industry and develop the U.K.’s own capabilities in these services.

UK GNSS program reinvented

The new program follows the work of the UK GNSS program, which concludes Sept. 30. UK GNSS began in 2018 as a result of Brexit and the U.K.’s departure from the Galileo program.

UK GNSS is an exploration programme that has developed outline plans for a conventional satellite system as an alternative to American GPS or the EU’s Galileo. The program will now be reset as the SBPP to build on this work to consider newer, more innovative ideas of delivering global satnav and secure satellite services to meet public, government and industry needs.

In 2018, the government announced an 18-month program, led by the UK Space Agency, to develop a conventional GNSS, which could meet U.K. security requirements and support the U.K.’s sovereign space and cryptography sectors.

Work completed by the UK GNSS Programme so far has developed cutting-edge British expertise in areas such as spacecraft and antenna design, satellite and ground control systems, systems engineering and simulation, which have wider applications across the space sector, in addition to supporting specialist U.K. jobs and industrial GNSS capability.

SBPP program to meet everyday needs

The refocused SBPP program could include technology that supports people’s everyday lives, such as emergency services to locate incidents, financial services companies to regulate exchanges on the U.K. stock market, or energy networks to ensure households receive power. Satellite navigation systems are also necessary to unlocking future technologies such as driverless cars, smart cities and artificial intelligence.

Capitalizing on the ingenuity of British businesses and academics, the program will explore the use of different kinds of satellites at various levels of orbit by exploiting technologies offered by companies at the cutting-edge of innovation such as OneWeb, Inmarsat and Airbus.

A Cabinet Office Study examining the need for a U.K. space-based system for secure positioning, navigation and timing concluded that any solution would need to examine more options and further work is needed to determine what form a potential system takes so it provides value for money.

To meet U.K. industry and government needs for resilient global navigation and timing while also providing value for money to the public, the new SBPP will consider collaboration with international allies to share satellite navigation services, costs and technology.

“Satellites underpin so many of the services that we all use every single day, from precise train timetables on our phones and satnavs in our cars,” said Business Secretary Alok Sharma. “Through our Space-Based Positioning Navigation and Timing Programme, we will draw on the strengths of the U.K.’s already thriving space industry to understand our requirements for a robust and secure satellite navigation system. This includes considering low-orbiting satellites that could deliver considerable benefits to people and businesses right across the U.K., while potentially reducing our dependency on foreign satellite systems.”

“I am delighted to see a further boost to the U.K.’s already thriving space industry,” said Scotland Office Minister Iain Stewart. “The U.K. government works closely with industry and academia to support the sector. We have high ambitions for the U.K. to be a global sector leader. The U.K. government is expanding its plans to understand requirements for a satellite navigation system. Satellite navigation provides the core services that we all use every day such as our mobile networks and is the key to unlocking further technical innovation in the future. This new programme will potentially pave the way for greater independence from foreign systems such as the United States’ GPS or the EU’s Galileo system which will allow greater opportunities for British businesses.”

“Our work to date has developed cutting-edge U.K. expertise in satellite navigation spacecraft, antenna design and control systems, while supporting high-skilled jobs,” Graham Turnock, CEO of the UK Space Agency said. “Now is the time to drive this work further to look into wider, more innovative ways of delivering this important national capability — to help protect our critical infrastructure and put the U.K. at the forefront of the development of new space technologies.”

Currently, the U.K. is entirely dependent on foreign systems for these critical navigation services. SBPP will enable to the U.K. to build on its thriving space industry, home to global players such as Inmarsat, Airbus, Surrey Satellites (SSTL) and others, to become a global leader in space navigation technologies, developing new opportunities for businesses in the U.K. and overseas and creating new highly skilled jobs.

The government has made clear its ambitions for the U.K. to become a globally competitive space power and is taking action through the newly established National Space Council, emerging National Space Strategy and the Integrated Review of Security, Defence, Development and Foreign Policy, to create the conditions for a strong, secure and innovative space sector that delivers for the British people.

A government-backed study from London Economics estimated that sustained disruption to existing satellite navigation capabilities would likely cost the U.K. economy £1 billion per day. Investment in space technology and services will enable the U.K. to build back better, unleashing the country’s global competitiveness and underpinning growth and high-skilled jobs.

With new space program, UK continues march to more holistic PNT

News from the British government appears to be a part of the United Kingdom’s diversification away from primary reliance on GNSS for positioning, navigation and timing (PNT) services, and toward a more diverse set of sources.

The nation has previously undertaken establishment of a National Timing Centre for distribution of time from suites of atomic clocks and has long transmitted an eLoran timing signal from a government facility in Anthorn.

Thursday’s press release, titled “Government to explore new ways of delivering ‘sat nav’ for the U.K.,” reinforces the government’s commitment to space-based PNT, but not necessarily from GNSS.

OneWeb satellites

The announcement follows significant criticism in Parliament of the nation’s purchase of a 45% share of the bankrupt communications satellite company OneWeb, with the India’s Bharti Holdings having the majority stake. OneWeb had 74 of its planned 648 satellites in orbit when it declared insolvency. With new ownership and financing in place, it plans to resume operations and launch another 36 satellites in December.

Prime Minister Boris Johnson’s motivation for making the investment was to offset Britain’s post-Brexit exclusion from Europe’s Galileo system. The idea was that OneWeb assets in low earth orbit (LEO) could provide a global British PNT capability.

This concept faced political and technical opposition from the start. Many technologists in the U.K. and elsewhere doubted that the constellation could be easily adapted to provide sufficiently accurate PNT services. The doubts were so serious that the senior career civil servant responsible for signing the agreement to invest in OneWeb took the very unusual step of refusing to do so without written direction from the political appointee she worked for.

Before the OneWeb investment, the U.K. government had been studying establish of its own GNSS like America’s GPS and Europe’s Galileo. Sources say the required investment was much higher than the nation wanted to make and would provide little added capability beyond that available from extant systems.

According to Thursday’s press release, the UK GNSS effort was exploratory and will end this month. It will be “reset” as the Space-Based Positioning Navigation and Timing Programme (SBPP). This project “will explore new and alternative ways that could be used to deliver vital satellite navigation services to the United Kingdom which are critical for the functioning of transport systems, energy networks, mobile communications and national security and defence, whilst boosting the British space industry and developing the U.K.’s own capabilities in these services.”

While the press release is short on detail, it does mention satellites at low earth orbit and that “a wider range of options” will be examined. This could suggest redoubling efforts on getting PNT from OneWeb, and/or investing in regional PNT satellites.

Galileo again?

The press release also says SBPP will “consider collaboration with international allies to share satellite navigation services, costs and technology.” This may signal reengagement with Europe on involvement with Galileo.

Some observers have said that Brexit did not have to automatically mean that the U.K. was excluded from the Galileo project. European Union membership is not required for participation in the European Space Agency which is responsible for Galileo. Switzerland and Norway, for example, are not EU members, but are members of ESA and sit on its governing board.

The U.K. government has been very concerned with PNT and GNSS vulnerability since at last 2012 when large solar flares became part of its National Risk Register. In 2017 a London Economics Report found that a five-day GNSS disruption would cost the nation more than $1.3B per day.

This most recent announcement indicates that Britain is still intent on going its own way and diversifying PNT sources, while still acknowledging the ongoing importance of GNSS and keeping its options open with allies.

Dana Goward is president of the Resilient Navigation and Timing Foundation. He is the proprietor at Maritime Governance LLC. In August 2013, he retired from the federal Senior Executive Service, having served as the maritime navigation authority for the United States. As director of Marine Transportation Systems for the U.S. Coast Guard, he led 12 different navigation-related business lines budgeted at more than $1.3 billion per year. He has represented the U.S. at IMO, IALA, the UN anti-piracy working group and other international forums. A licensed helicopter and fixed-wing pilot, he has also served as a navigator at sea and is a retired Coast Guard Captain.

The U.S. Federal Aviation Administration (FAA) has made it easier for drone pilots to quickly and safely access controlled airspace by adding 133 air traffic facilities to the Low Altitude Authorization and Notification Capability (LAANC) system. The expansion is based on feedback from the drone community.

LAANC is an automated application and approval system for drone pilots requesting to fly below 400 feet in controlled airspace.

As the FAA continues to modernize the national airspace to accommodate more users, the agency made LAANC accessible for 726 airports and 537 facilities, covering 81% of eligible airspace.

LAANC is a collaboration between the FAA and the unmanned aircraft systems (UAS) industry which directly supports the safe integration of drones into the nation’s airspace. The service is accessible to all pilots who operate under the FAA’s small drone rule.

GNSS reflectometry measurements improved with COVID-19 pandemic

Parked cars near ground station decreased accuracy from 2 to 4 centimeters

A new study shows that the quality of GNSS reflectometry measurements may have improved significantly during the pandemic because of the lack of cars parked near the ground station, according to Science Daily. GNSS reflectometry is used for earthquake early warning systems, determining flood risks, and many other geodesy applications.

The study, carried out by geodesists from the University of Bonn, investigated the location of a precise GNSS antenna in Boston, Massachusetts.

GNSS reflectometry works well if the surrounding ground is flat, like the surface of a mirror, study author Jürgen Kusche explained to Science Daily. “But many GNSS receivers are mounted on buildings in cities or in industrial zones. They are often surrounded by large parking lots — as is the case with the antenna we investigated in Boston.”

The researchers show that parked cars significantly reduced the quality of the elevation data by scattering the GNSS signals, causing them to be reflected several times before they reached the antenna, like a cracked mirror. This reduces signal intensity and provides “noisy” data — hard to correct with pattern recognition because the parked cars change positions every day.

“Before the pandemic, measurements of antenna height had an average accuracy of about 4 centimeters due to the higher level of noise,” Makan Karegar told Science Daily. “During the lockdown, however, there were almost no vehicles parked in the vicinity of the antenna; this improved the accuracy to about 2 centimeters.”

While GNSS stations were historically installed in sparsely populated regions, recent installations have been in urban areas to support engineering and surveying work.

“Our study recommends that we should try to avoid installation of GNSS sensors next to parking lots,” Karegar said.
