What improvements will GPS III bring to high -precision surveying? When? Will these improvements require any changes in equipment and/or processes?
Tony Agresta, Nearmap
“The biggest impact of GPS III to high precision surveying will be a full constellation of L5 satellites. Triple frequency will bring faster convergence times and better accuracy in more difficult conditions. GPS III will better align with Galileo and BeiDou with L1C which means better availability in restricted sky conditions. Users will want to have equipment capable of supporting these new signals, in antenna and receiver HW as well as the signal processing done on board.” Tony Agresta

“Of all the improvements brought by GPS III, the new L1C signal will probably have the biggest impact on high-precision surveying. Compared to L1 C/A, L1C brings better reception in difficult environments, improved availability thanks to the “pilot” component, enhanced resilience to jamming attacks, and better interoperability with Galileo, BeiDou and QZSS. Many receivers do support L1C already, but the benefits will become more tangible as the GPS III constellation grows.” Jean-Marie Sleewaegen

The months-long wildfires raging in Australia have killed at least 25 people. Millions — possibly 1 billion — animals have died. More than 2,000 houses have been destroyed. Around 150 fires are still burning in New South Wales and Queensland, with hot and dry conditions accompanied by strong winds fueling to the fires’ spread.
With this conflagration rocking the continent down under, satellite imagery has become important to understanding the scope of the disaster. Here are some of the recent captures.
As seen from the ISS
“Talking to my crew mates, we realized that none of us had ever seen fires at such terrifying scale,” European Space Agency astronaut Luca Parmitano tweeted on Monday, sharing photos taken from the International Space Station.
The astronaut posted images showing what he described as “an immense ash cloud” captured at the time the ISS was flying toward sunset.
An immense ash cloud covers Australia as we fly toward the sunset.
Another social media image, shared widely, was interpreted as a map showing the live extent of fire spread, with large sections of the populous eastern coastline molten red. Because of widespread misinterpretation, the original poster then explained that the image was a 3D visualization and not a photograph of Australia, and showed some areas where fires have been extinguished.
NASA and the U.S. Geological Survey’s Landsat 8 satellite imagery from Jan. 9 shows Kangaroo Island, home to nature reserves. The images were taken using the Operational Land Imager (OLI) on Landsat 8. Using natural-color observations, the images show burned land and thick smoke covering the island, of which at least 156,000 hectares have burned.

The U.S. National Oceanic and Atmospheric Administration (NOAA) satellites are also capturing images, including the resulting plumes of smoke.
Maxar collected satellite imagery Jan. 12 of the wildfires in New South Wales (NSW). The imagery shown below focuses on the area near the town of Eden, and demonstrates the value of the shortwave infrared (SWIR) sensor.
In an image taken with Maxar’s normal RGB color imagery, the smoky air prevents a clear view of the fires and the hot spots. With Maxar’s WorldView-3 satellite, however, the team is able to penetrate through the smoke using its SWIR sensor for a detailed look at the fire lines and burned vegetation.
With SWIR imagery, burning areas are apparent and show up in a glowing orange-red. Healthy vegetation shows up in shades of blue, and burned vegetation appears in shades of brown.

Copernicus Sentinel-3 imagery
Europe’s Copernicus Sentinel-3 mission has captured the multiple bushfires burning across Australia’s east coast.
In the above image, captured on Nov. 12, 2019, at 23:15 UTC (Nov. 13, 09:15 local time), the fires burning near the coast are visible. Plumes of smoke can be seen drifting east over the Tasman Sea. Hazardous air quality owing to the smoke haze has reached the cities of Sydney and Brisbane.
Flame retardant was dropped in some of Sydney’s suburbs as bushfires approached the city center, and many residents were evacuated. Firefighters continue to keep the blazes under control.
The Copernicus Emergency Management Service – Mapping was activated to help respond to the fires. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.
Quantifying and monitoring fires is fundamental for the ongoing study of climate, as they have a significant impact on global atmospheric emissions. Data from the Copernicus Sentinel-3 World Fire Atlas shows that there were almost five times as many wildfires in August 2019 compared to August 2018.
The U.S. Department of Transportation on Wednesday released updated guidelines for autonomous vehicles.
“Ensuring American Leadership in Automated Vehicle Technologies: Automated Vehicles 4.0” (AV 4.0) was announced by U.S. Transportation Secretary Elaine L. Chao in a keynote speech at CES 2020 in Las Vegas.
AV 4.0 unifies efforts in automated vehicles across 38 federal departments, independent agencies, commissions and executive offices, providing high-level guidance to state and local governments, innovators and stakeholders on the U.S. government’s approach toward autonomous vehicles.
“AV 4.0 will ensure American leadership in AV technology development and integration by providing unified guidance for the first time across the federal government for innovators and stakeholders,” Chao said.
AV 4.0 establishes federal principles for the development and integration of automated vehicles, consisting of three core focus areas: prioritize safety and security, promote innovation, and ensure a consistent regulatory approach.
It also outlines ongoing administration efforts supporting autonomous vehicle technology growth and leadership, as well as opportunities for collaboration including federal investments in the sector and resources for innovators, researchers and the public.
“AV 4.0 brings all of the important work happening on automated vehicle technologies across the federal government under one unified approach. The federal principles released today help foster an environment for innovators to advance safe AV technologies, and put the U.S. in a position of continued leadership in the future of transportation,” said U.S. Chief Technology Officer Michael Kratsios.
The USDOT is preparing for emerging technologies by engaging with new technologies to address legitimate public concerns about safety, security and privacy without hampering innovation, the department said in a press release.
With the release of “Automated Driving Systems 2.0: A Vision for Safety” (ADS 2.0) in September 2017, the USDOT provided voluntary guidance to industry, as well as technical assistance and best practices to states, offering a path forward for the safe testing and integration of Automated Driving Systems.
In October 2018, “Preparing for the Future of Transportation: Automated Vehicles 3.0” (AV 3.0) introduced guiding principles for autonomous vehicle innovation for all surface transportation modes, and described the USDOT’s strategy to address existing barriers to potential safety benefits and progress.
“AV 4.0 builds on these efforts by presenting a unifying posture to inform collaborative efforts in automated vehicles for all stakeholders and outlines past and current federal government efforts to ensure the United States leads the world in AV technology development and integration while prioritizing safety, security, and privacy and safeguarding the freedoms enjoyed by Americans,” the press release stated.
AV 4.0 will be published in the Federal Register for public review and comment. More information on the USDOT’s work on automated vehicles can be found at https://www.transportation.gov/av/4.

Augmenting GPS with other systems was suggested as the most promising area of improvement in a recently released memo establishing a Defense Science Board task force on positioning, navigation and timing (PNT).
On Dec. 16, the Department of Defense released a memo from Undersecretary Michael Griffin to the chair of the Defense Science Board. In it he outlined terms of reference for a year-long study of defense “position, navigation and timing control.”
Setting the stage for the effort, Griffin, who serves as undersecretary for research and engineering, outlined some challenges of relying too heavily on GPS. “The current system has less susceptibility to jamming and spoofing, but challenges remain — slow fielding of user M-code capability, cyber and kinetic threats. Degradation can occur in canyons, cities, and high signal multipath environments.”
He also seemed to indicate that, while further improvements to GPS were possible, they would likely yield only marginal returns and be very expensive.
“While performance and resilience continue to improve, the system has matured to the point that these changes have resulted in incremental improvement to overall system performance,” Griffin said. “The cost of the system and ongoing upgrades have experienced significant growth, making it hard to increase the density of the satellites to address the more challenging environments.
The memo suggests that, rather than focusing entirely on continual improvements to GPS, adding other systems to a PNT architecture for users will likely be more effective and economical.
One such addition may well be leveraging thousands of planned commercial communications satellites to also provide PNT.
“A future multi-mission constellation that can transmit and receive RF signal[s] across a broad spectrum will allow both the ability [to] provide and deny communication and PNT globally and will provide support to all essential warfighting missions,” Griffin said.
This idea is already being explored by Army Futures Command in partnership with the University of Texas at Austin’s Radionavigation Laboratory.
Yet Griffin cautions that using commercial communications satellites may or may not be a good idea. The memo asks the group to evaluate the benefits and risks of the military depending upon commercial systems.
Reinforcing the theme of focusing on architecture, Griffin’s final question to the study group deals with “the performance and resilience benefits” of adopting other PNT sources such as portable atomic clocks, visual sensors, and terrestrial-based navigation and timing.
This parallels the recently released DoD PNT Strategy, which calls for a wide diversity of PNT sources to create an architecture for greatly increased resilience and mission assurance. It envisions a multi-layered architecture of PNT sources with GPS providing a global layer, wide-area terrestrial systems like DARPA’s STOIC or eLoran for the regional layer, and short-range systems, interials, sensors and clocks providing the local layer.
The task force’s efforts are to conclude no later than February 2021, with a report by August of that same year.
A copy of Undersecretary Griffin’s memorandum is available here.
BCM4776 chip utilizes 30 new L5 signals to deliver higher navigational accuracy and yield
Photo: Broadcom
Broadcom introduced in 2017 the first mass-market implementation of dual frequency: BCM4775. This chip makes use not only of the classic L1 frequency broadcast by every satellite, but also of the more advanced L5 signal broadcast by a subset of the satellites.
The use of this enhanced L5 signal improves the accuracy of GNSS in an urban scenario, as it mitigates the main source of error: the reflections in the nearby buildings, also known as multipath. It also improves GNSS in an open-sky scenario, allowing submeter accuracy, a previously unmet performance bar in smartphones until now. Ever since, the BCM4775 has been adopted in flagship smartphones, smartwatches and fitness devices.
Given the unabated need for better precision and accuracy, Broadcom has introduced its second-generation dual-frequency GNSS solution — the BCM4776.
The new chip is capable of using the new BeiDou-3 constellation’s B2a signals (the Chinese indicator for L5). It will be able to track 30 new L5 signals (60 percent more) with a significant impact on accuracy. End users will experience much higher reliability of the submeter accuracy inherent to dual-frequency L1-L5.

Second generation dual-frequency GNSS will be used for innovative lane-level driving navigation instructions, allowing driving applications to know which highway lane the vehicle is in. Expect instructions like “move one lane to the right so you don’t miss your next highway exit” or “move one lane to the left to take the pool lane and save 10 minutes.”
Qualcomm Technologies unveiled at CES 2020 its newest addition to the company’s portfolio of automotive products — the Qualcomm Snapdragon Ride Platform.
Snapdragon Ride is an advanced, scalable and open autonomous driving solution consisting of the family of Snapdragon Ride Safety system-on-chips (SoCs), Snapdragon Ride Safety Accelerator and Snapdragon Ride Autonomous Stack.
CES 2020, the massive annual consumer electronics show, is taking place Jan. 7-10 in Las Vegas.
Snapdragon Ride aims to address the complexity of autonomous driving and ADAS by leveraging its high-performance, power-efficient hardware, industry-leading artificial intelligence (AI) technologies and pioneering autonomous driving stack to deliver a comprehensive, cost and energy efficient systems solution.
The unique combination of Snapdragon Ride SoCs, accelerator and autonomous stack offers automakers a scalable solution designed to support three industry segments of autonomous systems, namely L1/L2 Active Safety ADAS for vehicles that include automatic emergency braking, traffic sign recognition and lane keeping assist functions; L2+ Convenience ADAS for vehicles featuring Automated Highway Driving, Self-Parking and Urban Driving in Stop-and-Go traffic; and L4/L5 Fully Autonomous Driving for autonomous urban driving, robo-taxis and robo-logistics.
The Snapdragon Ride Platform, based on the Snapdragon family of automotive SoCs and accelerator, is built on scalable and modular heterogeneous high-performance multi-core CPUs, energy efficient AI and computer vision (CV) engines, industry-leading GPU.
The platform with combination of SoCs and accelerator can be used as needed to address every market segment offering industry-leading thermal efficiency, from 30 Tera Operations Per Second (TOPS) for L1/L2 applications to over 700 TOPS at 130W for L4/L5 driving.
The platform can therefore result in designs that can be passively or air-cooled, thereby reducing cost, and increasing reliability, avoiding the need for expensive liquid cooled systems and allowing for simpler vehicle designs, and extending the driving range for electric vehicles. The Snapdragon Ride SoCs and accelerator are designed for functional safety ASIL-D systems.
Snapdragon Ride is expected to be available for pre-development to automakers and tier-1 suppliers in the first half of 2020. Qualcomm Technologies anticipates Snapdragon Ride-enabled vehicles to be in production in 2023.
While the company believes the next wave of innovation may be in the L2+ Convenience ADAS segment, the hardware solutions utilized in Snapdragon Ride from a single system-on-chip (SoC) for an Active Safety ADAS system driven by regulatory mandates to a highly scalable architecture of multiple SoCs and dedicated autonomous driving accelerators allowing for fully autonomous self-driving systems.
Qualcomm Technologies’ family of ADAS SoCs and accelerators are built on the fundamental approach of heterogeneous compute capabilities designed for application requirements.
These ADAS SoCs and accelerators effectively manage a large amount of data from onboard systems, leveraging Qualcomm Technologies’ next generation AI engines; image signal processors for camera sensors; enhanced digital signal processors (DSPs) for sensor signal processing; high-performance CPUs for planning and decision making; cutting-edge GPU technology for high-end visualization and immersive user experience; dedicated safety and security subsystems across the SoC and autonomous driving accelerator.
Through the autonomous driving accelerator, Qualcomm Technologies brings energy efficient compute capabilities to mainstream vehicles, which has so far been largely unavailable to the automotive industry due to exceptionally complex and expensive thermal solutions that are fundamentally unscalable because of their power consumption requirements.

HERE is also working across a partner ecosystem — including reference station operators, chipset manufacturers, module makers, hardware vendors, mobile network operators and system integrators — to jointly improve the positioning accuracy to centimeter levels, and in more challenging environments such as urban canyons.
Automotive use cases
Autonomous driving. For safety, it’s critical that automated vehicles are designed with high levels of redundancy in positioning systems. If an automated vehicle gets caught in bad weather conditions which are degrading optical sensor operations, <0.2m positioning accuracy available via HD GNSS increases safety and operation time in autonomous mode.
Assisted driving. In case of an obstacle on the road, HD GNSS combined with HERE HD maps provide obstacle indication and avoidance functionality.
Mobile device use cases
Road lane guidance and improved ETAs on mobile devices. If a driver is unfamiliar with the roadway, HERE HD GNSS, combined with precision HERE map data, shows the driver the correct lane and path to navigate to the destination fast and safely.
Improved gaming and augmented reality experience. Location-based games are growing and widely popular, however they currently rely on less accurate positioning technologies that inhibit next generation use cases. HERE HD GNSS bring exciting opportunities to design the next version of games with sub-meter positional accuracy.

Hexagon/NovAtel announced that shipments of next-generation ground uplink station (GUS) signal generators have commenced in fulfillment of its contract with the United States Federal Aviation Administration (FAA) to support the FAA’s safety of life wide-area augmentation system (WAAS) navigation service.
Developed by the FAA for civil aviation, WAAS is a safety-critical navigation aid that provides integrity monitoring and differential corrections for all phases of flight. The next-generation NovAtel GUS signal generator replaces the legacy product that has operated successfully for more than 15 years and ensures continued operation for years to come.
Along with the GUS signal generator modernization, the contract includes ongoing engineering support services for the complete portfolio of NovAtel ground reference receiver products deployed by the FAA.
“We have a long-standing relationship with the FAA and worked very closely with the WAAS program team to deliver this critical next-generation technology for SBAS modernization,” stated Jonathan Auld, NovAtel Vice President of Engineering and Safety Critical Systems. “We’re very pleased to continue our commitment to support the FAA and their safety of life WAAS service.”
