Iridium Satellite Communications Inc. filed comments to the U.S. Federal Communications Commission (FCC) on Oct. 29 regarding outdated Ancillary Terrestrial Component (ATC) rules.
The company, operator of the Iridium satellite constellation — 66 low-Earth orbit satellites used for global voice and data communication from handheld satellite phones and other transceiver units — called for the rules to be removed by the FCC and replaced by new rules that better serve the spectrum ecosystem.
“Fifteen years ago, the FCC had a vision of satellite companies integrating terrestrial service into their core satellite business as a supplemental service. This vision has been never been successfully achieved — not once,” said Iridium spokesperson Jordan Hassin. “Instead, the result has been a constant whittling away at the rules to the point they have become irrelevant with a whole lot of collateral damage along the way. Given this history, it is appropriate for the FCC to consider the elimination of these outdated ATC rules while taking into account the realities of existing services and users.”
“ATC is an outdated concept that never developed as intended,” Rob McDowell, former commissioner of the FCC added.
The rules have resulted in proposals to get around them, such as Ligado, and significant fights over harmful spectrum interference to incumbent satellite systems. Ligado has sought to waive three gating criteria established by the FCC.
The Federal Aviation Administration’s (FAA) nationwide deployment of the Low Altitude Authorization and Notification Capability (LAANC) has exceeded all of the program’s original objectives.
Since the program began with a prototype system in November 2017, LAANC has processed more than 50,000 applications from drone operators for authorization to fly in controlled airspace. The system now covers almost 300 air traffic facilities serving approximately 500 airports, providing near-instantaneous approvals and allowing operators to quickly plan their flights. View a list of the participating facilities.
LAANC helps support the safe integration of drones into the nation’s airspace. The system uses airspace data provided through temporary flight restrictions, Notices to Airmen (NOTAMs) and unmanned aircraft system (UAS) facility maps that show the maximum altitude ceiling around airports where the FAA may authorize operations under Part 107, the small drone rule for commercial and public agency operators.
LAANC Service Suppliers
The FAA has approved 14 LAANC service suppliers. Instructions on how to apply are provided by each supplier:
Drone operators also can file for airspace authorizations using the FAA DroneZone, including for areas not covered by LAANC or when the operator holds a Part 107 waiver.

Drone surveying software Virtual Surveyor now eliminates the need for clients to use third-party applications to prepare data for processing. Released this week, Virtual Surveyor 6.1 now handles on-the-fly projections that previously required a separate software package to set the data in the proper coordinate system.
“We have developed a completely new project experience for users of UAV data,” said Tom Op ‘t Eyndt, managing director of Virtual Surveyor in Belgium. “Version 6.1 will save our customers time and money once spent converting their drone data for processing in Virtual Surveyor.”
Virtual Surveyor bridges the gap between UAV photogrammetric processing applications and engineering computer-aided design (CAD) packages. The software generates an interactive onscreen environment with UAV orthophotos and digital surface models where the surveyor selects survey points and breaklines to define the topography, creating highly accurate topographic products for CAD input up to five times faster than otherwise possible.
“Our value proposition has always been to enable surveyors to derive topographic information from drone data and deliver the light-weight meaningful CAD model that engineers need,” said Op ‘t Eyndt.
Prior to Version 6.1, users always had to start from an orthophoto and digital surface model (DSM). Now, surveyors can drag and drop all kinds of files into Virtual Surveyor: points, raster, vectors and point clouds. The point clouds are converted to a DSM for manipulation and processing, dramatically accelerating the time required to generate the CAD model.
“Not only is this faster, but it eliminates the expense of purchasing additional software,” said Op ‘t Eyndt.
Some customers asked to work only with a CAD file, he explained. Although they work with drone data most of the time, they occasionally had to create a surface or contours from a traditional survey. They asked if this could be done in Virtual Surveyor as it would save them from paying for a subscription to a CAD software.
Long-time Virtual Surveyor clients will find the entire project experience has been streamlined and improved with new capabilities in V6.1:
Start from any data set. Projects can now be initiated from Orthophotos, DSMs, Point Cloud or CAD files.
Convert coordinates on the fly. Users can input data in any coordinate system and convert it during processing to another system after the project has begun.
Developers of Virtual Surveyor have also added these features to V6.1:
Automatic creation of section lines. V6.1 automatically generates sections from road surfaces to survey transportation routes in minutes.
Transparent layers. Users can add topographic or cadastral data to their project and view it through the orthophoto layer to annotate or draw boundaries.
“Overall, users will experience a faster processing environment in Virtual Surveyor 6.1 especially during complex tasks, such as making terrain modifications or calculating volumes,” said Op ‘t Eyndt. “Our goal with this version has been to make professional land surveyors more efficient.”
Current subscribers to Virtual Surveyor will see their software being updated automatically.
NextNav’s Metropolitan Beacon System (MBS) service has been accepted for use by NASA. NASA will use NextNav’s MBS network as part of its CERTAIN (City Environment for Range Testing of Autonomous Integrated Navigation) facilities at NASA’s Langley Research Center in Hampton, Virginia.
CERTAIN supports, among other programs, Urban Air Mobility (UAM), an air transportation system with myriad applications from small package delivery drones to passenger-carrying air taxis.
The Federal Aviation Administration (FAA) believes that by 2022 there will be more than 700,000 drones delivering packages, monitoring traffic and aiding in search and rescue operations. NASA’s role is to provide research findings to reduce technical barriers associated with integrating unmanned aircraft systems into the national airspace system.
NextNav’s MBS system facilitates urban drone operations where satellite-based GPS signals may not be available. The need to reliably know a drone’s location horizontally and vertically is critical to ensure safe operations in urban air traffic corridors.
Uber in the Mix. Uber and Bell (formerly Bell Helicopter) plan to launch an on-demand mobility venture, or flying taxis, nationwide by 2023, so the need to precisely track vehicles moving throughout city airspace is imminent.
The move to such flying taxis would require a change to current FAA-controlled airspace separation requirements, according to Tom Prevot, Uber’s director of airspace systems. He stated that the Uber venture foresees takeoffs and landings from city vertiports every 24 seconds, requiring a considerable reduction in the minimum-distance standards of 1,000 feet vertically or 3 to 5 nm horizontally, as currently mandated in FAA order JO 7110.65.
Metro Beacons. “NextNav’s MBS system provides us with new tools for the development of navigation systems in environments where GPS has traditionally been challenged,” said Evan Dill, Safety-Critical Avionics Systems Branch of NASA. “We’re looking forward to working with MBS as we develop new approaches to the operation of unmanned systems in urban environments.”
NextNav’s wide-area terrestrial positioning network provides accurate and secure location services, critical for unmanned aircraft navigation. In addition, MBS complements and integrates seamlessly with GPS and provides a level of geo-redundancy ensuring a safe and efficient system for future air transportation in cities and urban areas, with particularly difficult challenges at low altitudes where solutions such as radar, GPS and ADS-B are unreliable or insufficient.
Delivered over a managed network on nationwide licensed spectrum with carrier-grade dependability and metropolitan-wide coverage, NextNav said its services are designed for public safety applications, E911, critical infrastructure, as well consumer, Internet of Things (IoT) and commercial applications that require reliable 3D geolocation indoors and urban areas or precise timing.

“We are proud to work with NASA and integrate MBS into its urban drone operations,” said Ganesh Pattabiraman, co-founder and CEO of NextNav. “The MBS system is designed for secure, reliable and consistent 3D geolocation capabilities, which are important for autonomous systems such as drones. NASA’s acquisition of the MBS system is an exciting milestone for MBS technology and a great partnership with NASA to address the key challenges in urban drone navigation and make it possible to explore new opportunities in unmanned operations.”
Update: The Camp Fire is now the deadliest fire in California history, claiming more than 50 lives.
DigitalGlobe’s WorldView-3 satellite collected new imagery of the deadly Camp Fire near Paradise, California.
The Camp Fire, which broke out Nov. 8, destroyed 90 percent of the town of Paradise. At least 29 people have died, making it the deadliest wildfire in the state’s history in more than 85 years, while more than 200 people are unaccounted for. Firefighters are still trying to contain the roaring blaze.
Here is a link to download a set of satellite images as well as a map graphic (PDF file). The satellite images include a couple of different views of the fire including:
A natural color overview of the area. The smoke from the wildfire obscures much of the area around Paradise and the surrounding communities.
Shortwave Infrared (SWIR) images of the area. SWIR images from our satellite can penetrate smoke caused by the fire and help clearly identify the fire lines and areas that have burned/are burning.
A rotated SWIR view of the fires, in case the orientation would be more useful for your graphic teams.
A reference image/map graphic (see PDF file) that should help you correlate the images to the locations on the ground.
Association recognizes key role the agency has played in furthering GPS.
The GPS Innovation Alliance (GPSIA), an organization dedicated to furthering GPS innovation, creativity and entrepreneurship, commends NASA — the U.S. National Aeronautics and Space Administration — on its momentous 60th anniversary. GPSIA celebrates the occasion by recognizing the vital role NASA has played in furthering and facilitating the growth of GPS around the world.
NASA has long been an integral supporter of GPS technologies, from its origins in the first space shuttle program, to the launch of the International Space Station (ISS), to the recent announcement of plans to develop an artificial intelligence-based GPS for space.
Throughout its history, NASA has played a critical role in the success of expanding GPS systems. NASA manages the Navigator GPS receiver, developed by its Goddard Space Flight Center, which has pushed GPS satellites out of lower earth orbit and beyond to enable high altitude applications and track weaker and more rural GPS signals with increased accuracy.
The Global Differential GPS System (GDGPS), a network of more than 350 GPS monitoring stations from 200 contributing organizations in 80 countries developed and operated by NASA’s Jet Propulsion Laboratory, provides an unparalleled combination of real time positioning accuracy and availability and acts as the largest network providing global, multiply-redundant, real time coverage of all GPS satellites at all times.
“GPS contributes immeasurable value to our economy and is used in almost every industry sector,” said NASA Administrator Jim Bridenstine. “It is crucial for our way of life on Earth — the way we communicate, navigate, conduct banking transactions, and so much more rely on our GPS systems. As NASA looks to its future endeavors in exploration and discovery, GPS will remain a cornerstone of technology to accomplish its missions. NASA looks forward to its continued work with the GPS Alliance.”
With the establishment of the National Executive Committee for Space-Based Positioning, Navigation, and Timing in 2004 and other governing bodies since, NASA has also acted as a thought leader on policy trends in the field, advising on and advocating for protections of GPS , one of the world’s most important and ubiquitous public resources.
“The alliance, on behalf of its members and the GNSS industry, congratulates NASA on six decades of cutting-edge innovation and wishes the agency continued success for many decades to come,” said J. David Grossman, executive director of the GPS Innovation Alliance. “As one of the most recognizable technologies in the world, GPS supports navigation, public safety, financial transactions and utilities and varied industries worldwide. We applaud NASA for its unwavering commitment to scientific innovation and to GPS around the globe, now and in the future.”
The GPS Innovation Alliance recognizes the ever increasing importance of GPS and other GNSS technologies to the global economy and infrastructure and is firmly committed to furthering GPS innovation, creativity and entrepreneurship. The GPS Innovation Alliance seeks to protect, promote and enhance the use of GPS.
