  1. On June 26, the U.S. National Oceanic and Atmospheric Administration (NOAA) released the summary of the results of Commercial Weather Data Pilot (CWDP) Round 2. View the summary here. In Round 2, NOAA evaluated GNSS radio occultation data from two U.S. commercial space companies: GeoOptics and Spire. NOAA concludes that, based on the results of CWDP Round 2, the commercial sector is able to provide radio occultation data that can support NOAA’s operational products and services. “As a result, NOAA is proceeding with plans to acquire commercial RO data for operational use,” the summary states. According to GeoOptics, the report highlights the unique qualities of its commercial GNSS-RO data and its ability to improve weather and space weather forecasts around the world. “As today’s report demonstrates, commercial satellite data will enable NOAA to make significant improvements in forecasting worldwide within the consistent budget limitations under which it operates,” said GeoOptics CEO Conrad Lautenbacher. NOAA anticipates release of a request for proposals soon for operational purchase of commercial radio occultation data, continuing an acquisition process that began in April with NOAA’s release of a draft Statement of Work. NOAA has requested $15 million in FY 2021 to support Commercial Data Purchase. The FY 2021 Budget also requests $8 million for CWDP to investigate new commercial technologies beyond radio occultation. By moving into this next phase of engagement with U.S. industry, NOAA is leveraging commercial space sector capabilities to support its operational products and services and to continue to improve its weather forecasting capabilities. NOAA plans to implement additional rounds of the CWDP to evaluate commercial capabilities beyond radio occultation data for potential operational use. source: https://www.gpsworld.com/noaa-report-supports-gnss-ro-for-weather-and-space-forecasts/
  2. Septentrio has launched the mosaic-T GPS/GNSS receiver module, built specifically for resilient and precise time and frequency synchronization under challenging conditions. According to the company, its multi-frequency, multi-constellation GNSS technology — together with AIM+ Advanced Interference Mitigation algorithms — allows mosaic-T to achieve maximal availability even in the presence of GNSS jamming or spoofing. This compact surface-mount module is designed for automated assembly and high-volume production. “We are excited to expand our mosaic GNSS module family with mosaic-T, which will provide critical infrastructure and mission-critical PNT applications with accurate, reliable and resilient timing solutions,” said Francois Freulon, head of product management at Septentrio. Septentrio mosaic-T delivers timing with nanosecond-level accuracy and has additional inputs for an external high-accuracy clock, the company added. Septentrio, headquartered in Leuven, Belgium, designs and manufactures multi-frequency multi-constellation GPS/GNSS positioning technology for demanding applications. source: https://www.gpsworld.com/septentrio-launches-mosaic-t-gnss-receiver/

  4. SBG Systems has announced the third generation of its Ellipse series of miniature inertial sensors. The renewed product line benefits from a 64-bit architecture, allowing high precision signal processing. All of the INS/GNSS devices now embed a dual-frequency, quad constellations GNSS receiver for centimetric position and higher orientation accuracy. SBG Systems manufactures miniature high-accuracy inertial navigation systems with inertial measurement unit (IMU) design, calibration and filtering. All improvements made in the high-end lines could naturally benefit the Ellipse miniature line. The Ellipse series includes four models. Ellipse-A is a motion sensor Ellipse-E provides navigation with an external GNSS receiver Ellipse-N is a single-antenna RTK GNSS/INS Ellipse-D is a dual-antenna RTK GNSS/INS With its new 64-bit architecture, the third-generation Ellipse series enables the use of high-precision algorithms and technology used in high-end inertial systems such as rejection filters and FIR filtering. All Ellipse miniature INS are now RTK-enabled without extra cost, and output raw data for post-processing. All these features are made possible in a small, robust aluminum-enclosure box version, as well as in the 17-gram OEM version. The 17-gram OEM version of the Ellipse-D can provide drones with high-end features. Its dual antennas gives UAVs robust instant heading for take-off. Dual antenna is achievable with a very short baseline, down to 50 centimeters. Integration is enabled with ROS and PX4 drivers , full API, and free phone and email technical support. Ellipse-D Ellipse-D is the smallest dual-frequency, dual-antenna RTK GNSS/INS device offered. With its dual-frequency RTK GNSS receiver, the Ellipse-D provides a centimeter positioning. Dual frequency provides more robust heading and position computation than single-frequency receivers. It also allows high performance in attitude (0.05°) and in heading (0.2°). With its dual-antenna capability, Ellipse-D provides precise heading in a few seconds, in all dynamic conditions, and even in challenging GNSS conditions. It is also immune to magnetic disturbances. Ellipse-D is a quad-constellation receiver, simultaneously using signals from GPS, GLONASS, BeiDou and Galileo to enable navigation in challenging conditions. Designed with high quality industrial-grade components, Ellipse inertial sensors are highly tested and calibrated in dynamic and temperature for consistent, repeatable behavior in all conditions. source: https://www.gpsworld.com/sbg-systems-advances-gnss-ins-with-3rd-generation-ellipse/
  5. The big news in the geospatial world at the moment is Facebook’s acquisition of Mapillary. For those unfamiliar, Mapillary is a darling of the mapping world and one of the highest-profile geospatial startups of the last decade—launched in 2013, their mission was to create a global street-level imagery dataset to rival Google Street View. Mapillary was the prototypical “venture-scale” business — preposterously ambitious, technically impressive, inarguably valuable for the world, and plausibly monetizable. What Mapillary accomplished in a short seven years is simply staggering. Google, with an enormous head start and untold resources at the ready to support Street View announced last year that they’ve collected over ten million miles of street imagery. Mapillary, on the other hand, crossed three million miles of mapped streets in 2018 and has more than doubled the number of images in their catalog in the years since (to over one billion!), putting them squarely in the same conversation as Google. That’s an insane accomplishment for any company, let alone a startup who, over its lifetime, raised ~$25M or about half of the annual compensation package for a typical member of Google’s C-Suite. In addition, they’ve created some stuff I deeply admire as a member of the broader open source geospatial community. Two quick examples: OpenSfM, a popular computer vision engine for stitching together overlapping images to reconstruct places in 3D. Vista, a free 25K image dataset labeled for semantic segmentation — one of the largest such open datasets in existence. What is Facebook Up To, Exactly? If you predicted Facebook would acquire Mapillary, congratulations — you are probably alone. Apart from a public image that stands in cartoonish opposition to Mapillary’s ethos of grassroots community building and radical openness, Facebook doesn’t really do maps, do they? Google, Apple, and Microsoft have invested billions into consumer mapping applications and acquired numerous companies to support those efforts. Any of those three behemoths would have felt like natural landing spots for Mapillary. But Facebook? What’s that about? Unless you are already tapped into the seedy underworld known as the “geospatial industry,” you can be forgiven for not knowing that Facebook actually does do maps. In this incredible paper¹ released j̶u̶s̶t̶ ̶l̶a̶s̶t̶ ̶m̶o̶n̶t̶h̶ just over a year ago², researchers found that Facebook has contributed over 800,000 kilometers of mapped roads to OpenStreetMap (if you’re unfamiliar, it’s one of the largest crowdsourcing projects in history). They rank third in kilometers mapped behind Mapbox/Development Seed (1.69M) and Apple (1.64M). And beyond directly contributing cartographic features to OSM, they’ve publicly released an open source, AI-assisted road mapping tool called RapID that is an impressive thing to witness in action. They also support the OSM Foundation at the highest corporate giving level and have had a formidable presence at the annual OSM conference the past few years. Still — the mere fact Facebook has dipped its gargantuan toes into the mappy water doesn’t explain why they would bother with acquiring Mapillary. complete story: https://medium.com/@joemorrison/why-on-earth-did-facebook-just-acquire-mapillary-9838405272f8
  6. This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does not come to an abrupt halt at the bottom of the gravitational pit. Instead, a path can be traced out again but you do not end up in the universe that you started in. Like I said, it’s a map of the multiverse.
  7. The United States Space Force’s GPS III program reached another milestone with the successful core mate of GPS III Space Vehicle 08 at Lockheed Martin’s GPS III Processing Facility in Waterton, Colorado, April 15. With core mate complete, the space vehicle was named in honor of NASA trailblazer and “hidden figure” Katherine Johnson. The two-day core mate consisted of using a 10-ton crane to lift and complete a 90-degree rotation of the satellite’s system module, and then slowly lowering the system module onto the satellite’s vertical propulsion core. The two mated major subsystems come together to form an assembled GPS III space vehicle. Despite the COVID-19 pandemic, the Space and Missile Systems Center (SMC) and its mission partner Lockheed Martin ensured that SV08 core mate took place, in accordance with all Centers for Disease Control and local guidelines to minimize exposure or transmission of COVID-19. The GPS III Processing Facility’s cleanroom high bay was restricted to only key personnel directly supporting the operation. “Core mate is the most critical of the GPS space vehicle single-line-flow operations,” said Lt. Col. Margaret Sullivan, program manager and materiel lead for the GPS III program. “Despite the restrictions presented by the COVID-19 pandemic, our team adapted and worked tirelessly to achieve this essential milestone.” Katherine Johnson. When the core mate operation is successfully completed, a GPS III satellite is said to be “born.” In keeping with the team’s tradition of naming GPS III satellites after famous explorers and pioneers, SV08 was named “Katherine Johnson” in honor of the trailblazing NASA mathematician and “human computer” who designed and computed orbital trajectories for NASA’s Mercury, Apollo and space shuttle missions. One of four African-American women at the center of the nonfiction book by Margot Lee Shetterly and the movie Hidden Figures, Johnson was awarded the Presidential Medal of Freedom in 2015 for her groundbreaking contributions to the U.S. space program. Other GPS III satellites have been named in honor of explorers including GPS III SV01 “Vespucci” after Amerigo Vespucci; GPS III SV02 “Magellan” after Ferdinand Magellan; and GPS III SV03 “Columbus” after Christopher Columbus. Next up, performance tests. The next step for the newly christened “Katherine Johnson” is the post-mate Systems Performance Test (SPT) scheduled to begin in August. SPT electrically tests the performance of the satellite during the early phase of build and provides a baseline test data set to be compared to post-environmental test data. GPS III SV08 is currently scheduled to launch in 2022. GPS III is the most powerful GPS satellite ever developed. It is three times more accurate and provides up to eight times improved anti-jamming capability over previous GPS satellites on orbit. GPS III brings new capabilities to users as a fourth civilian signal (L1C), designed to enable interoperability between GPS and international satellite navigation systems, such as Europe’s Galileo system. GPS III satellites will also bring the full capability of the Military Code (M-code) signal, increasing anti-jam resiliency in support of the warfighter. These continued improvements and advancements to the GPS system makes it the premier space-based provider of positioning, navigation, and timing services for more than four billion worldwide. GPS III SV03 to Launch June 30. Launched in December 2018 and August 2019, GPS III SV01 and SV02 became part of today’s operational constellation of 31 satellites, on January 13 and April 1, 2020 respectively. GPS III SV03 is scheduled to launch on June 30. The SMC, located at the Los Angeles Air Force Base, California, is the center of excellence for acquiring and developing military space systems. Its portfolio includes the GPS, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems, and space situational awareness capabilities. source: https://www.gpsworld.com/gps-iii-sv-08-born-with-core-mate-complete-named-katherine-johnson/
  8. Researchers have developed an algorithm that can distinguish between volcanic and non–volcanic clouds using high-resolution satellite imagery. Called the Cloud Growth Anomaly (CGA) technique, the algorithm uses geostationary satellite data to detect fast growing vertical clouds caused by volcanic output. Volcanic ash produced by eruptions are a major threat to airplanes. In 2011, for example, Grímsvötn erupted, closing Iceland’s air space. Volcanic ash can cause significant damage to airplanes including in-flight engine failure. Researchers noted that “volcanic clouds produced by explosive eruptions can reach jet aircraft cruising altitudes in as little as 5 minutes.” Ten or more eruptions occur each year with a plume reach at or above jet cruising altitudes. Despite this threat, the authors of this study further note that “90% of the world’s volcanoes are not regularly monitored for activity.” Geostationary weather satellites such as Himawari-8 and the GOES East and West satellites provide high resolution data that can be used to detect ash plumes. Currently, Volcanic Ash Advisory Centers (VAACs) tend to manually analyze satellite imagery due to limitations with discerning ash plumes from meteorological clouds using multispectral infrared-based techniques. In this latest study, the CGA technique uses infrared measurements on satellite imagery “to identify cloud objects and compute cloud vertical growth rates from two successive images” produced within 60 minutes of each other. The CGA method was applied to 79 different explosive volcanic events from 30 volcanoes between 2002 and 2017. The success rate of the CGA in correctly identifying ash clouds varied depending on whether it was applied to the latest generations weather satellites. On older satellites, the accuracy rate was about 55%. For new generation satellites such as Himawari-8, the accuracy rate rose to 90%. source: https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2018EA000410
  9. Volcanoes present potential hazards not only to human life around these features but also to scientists studying them. With the increase usage of unmanned aerial vehicles (UAVs), or drones, scientists now have a powerful tool to better monitor active volcanoes without getting into a dangerous situation. While being safer to use than traditional monitoring, UAVs can also help deliver vital data to better learn about volcanoes that can help better predict eruptions and how they may disrupt travel and other activities. Among the many benefits, rotary and fixed-wing drones can provide aerial survey around major volcanoes. This includes using optical and thermal imaging capabilities to provide detailed surveys and monitoring for any shifts in volcanic activity. Recently, the German Research Centre for Geosciences (GFZ) in Potsdam carried out a survey over the Santa Maria volcano in Guatemala, where the lava dome, including viscous lava emitted, were observed. Results of this survey demonstrated that the lava dome has two types of active growth and change, something not observed previously, which included slow expansion and extrusion of lava in the dome. Interestingly, the types of cameras allowed the researchers to make measurements that scientists often want without having to deploy equipment on the volcano, including measuring lava flow velocity, movement patterns of the lava dome, and surface temperature of the volcano. This was all done using high resolution stereo photographic equipment. This also allowed a 3D model of the volcano to be made that also included temperature estimates throughout the volcano. The key demonstration is that some of the most dangerous volcanoes could not only be monitored more safely but the data could also be used to predict potential eruptions, as changing properties could be nearly continuously monitored through the deployment of UAVs.[1] This research is similar to an earlier work that also mapped an active volcano using 3D imagery and thermal imaging, demonstrating some similar results.[2] There have been many other research projects deploying UAVs. This includes using UAVs to monitor active eruptions such as on Mount Etna in Sicily, including measuring the volume of lava flow. In this case, a digital elevation model (DEM) was created using points from optical monitoring that was then used to create a 3D map and volume estimate on how much lava was flowing from an eruption event. This can help monitor the scale and size of eruptions, helping to provide data on how dangerous given volcanic events could be to human life and property.[3] Additionally, it was shown that UAVs are useful for long-term monitoring as volume changes in a volcano. In a study in Indonesia, UAVs were used to monitor and measure volume loss and gained during explosions using photogrammetry measurements. The study demonstrates the importance of structure mapping and long-term monitoring of volcanoes.[4] While most studies have used UAVs near volcanoes, or even sometimes flying them inside the area of a volcano, other work has also used high altitude fixed-wing UAVs, which flew outside of visible line of sight, to monitor plumes which can disrupt air travel. In the study that was carried out in Guatemala, plume‐detection and measurement was utilized used sensors carried by a UAV, which also captured atmospheric data that could combined with the plume data. Measuring the plumes and potential hazardous ash and tephra enables a safe way to monitor how dangerous plumes could be to air travel. The work demonstrates that multi-scale data, including near and farther away, are needed to better monitor volcanoes, where understanding plumes during an eruption are also critical for safety.[5] Increasingly over the last decade, UAVs have been utilized to monitor different aspects of volcanoes, including their active states and as they expand their lava domes prior to eruption. Additionally, monitoring plumes can provide a better way to give warning to flights and provide an indication on how dangerous volcanic eruptions could be to air travel. With increasing ways in which volcanoes can be monitored using UAVs, we should begin to learn more about volcanic behavior without having to put people and expensive instruments in potential harm. source: https://www.gislounge.com/monitoring-volcanoes-using-uavs/
