Santa Claus will be performing a ceremonial fly-by of the International Space Station (ISS) on Dec. 24. The visit will honor the 20th anniversary of continuous life on the ISS, a milestone achieved in November.
The official NORAD Santa Tracker at NoradSanta.org will allow users to track Santa’s journey all day on Dec. 24. New for this year, visitors will be able to see the ISS orbiting the planet in its precise real-time location by zooming out on the 3D Santa Tracker app. Other updates include additions to Santa’s traditional garb, including a face mask and space helmet.

“The ISS is a spectacular example of what humans can accomplish when we work together,” said Hannah Pinkos, lead developer of the app. “2020 has been a tough year, but I think this special trip is Santa’s way of reminding us to believe in ourselves.”
NORAD, the North American Aerospace Defense Command, is a United States and Canada bi-national organization that defends North America by tracking objects flying in and around its airspace 24 hours a day using radar, satellites and fighter jets. Each year, it joins corporate partners in taking on a special mission to also track Santa’s sleigh. The app shows Santa’s position reflected on a digital twin of the Earth provided by Cesium, a Philadelphia-based geospatial software company.
“Cesium is rooted in aerospace, so it’s especially meaningful to us that our technology will allow millions of people to enjoy this event in real-time from the safety of their homes,” added Cesium CEO Patrick Cozzi.

Startup Angsa Robotics was named the overall winner of the Galileo Masters 2020 competition for its autonomous rubbish robot.
According to Angsa Robotics, “Clive” is Germany’s first autonomous rubbish robot. It can move independently and detect and localize individual objects based on its unique artificial neural network architecture, which enables it to clean grass and gravel areas. In addition, individual objects such as crown caps or cigarette butts are targeted for collection, but insects are spared.
The robot’s target use cases include cleaning festival venues after events and the daily cleaning of parks and other green spaces. It can be used where conventional sweeping machines designed for flat asphalt surfaces cannot be used, Angsa Robotics said.
Precise localization via GNSS is essential to its operation, Angsa Robotics added. With better localization, “Clive” can plan a more efficient path and clean a given area faster.
“Angsa Robotics is another concrete example of the innovation and applications that GNSS is enabling for the benefits of business, society and the environment,” said Rodrigo da Costa, executive director of the European GNSS Agency (GSA). “The combination of precise GNSS localization with further state-of-the art techniques such as artificial intelligence and robotics captures in a nutshell the spirit of the three challenges in this year’s edition of Galileo Masters.”
The Galileo Masters’ network of 101 partners from 18 countries focuses on the regional implementation of the competition to ensure a high level of diversity while enhancing both job growth potential and regional development opportunities. At the 2020 Space Awards, seven challenge winners were honored by representatives of the European Commission, GSA, the German Aerospace Center (DLR), and the German Federal Ministry of Transport and Digital Infrastructure.
The Galileo Masters, founded by AZO, DLR and the Bavarian State Ministry of Economic Affairs and Media, Energy and Technology, annually awards the best services, products, and business ideas using satellite navigation in everyday life.

According to the company, its lidar imagery was used to generate as-built conditions of a steep ravine to aid in long-term monitoring of the slopes under which a natural gas pipeline was buried.
A narrow road traversing the top of the ravine through which the pipeline was installed was of concern since the instability could be dangerous. Loss of vegetation along the buried pipeline’s path also makes the area especially susceptible to slides after heavy rainfall.

The RTL-400’s high-resolution point cloud data of the 13-acre ravine area was captured in 10 minutes, RedTail Lidar Systems said. The as-built digital elevation model (DEM) created from the lidar point cloud can be compared to future DEMs to determine if any changes have occurred in the slope’s topology, which would serve to identify hazards and provide input for slip mitigation.
RedTail Lidar Systems is a division of 4D Tech Solutions, a company focused on providing innovative technology-based solutions to address government and commercial customer needs.

My last column described a new National Geodetic Survey (NGS) webtool for obtaining geodetic information about a passive mark in their database. The column highlighted some features that may be of interest to GNSS users. It provides all of the information about a station in a more user-friendly format. This column highlights an ArcGIS web application that incorporates various California specific datasets and NGS data layers to assist surveyors planning vertical control surveys. The GNSS Leveling Web Application was provided to me by Jay Satalich, chief, Office of Surveys, Caltrans (see box titled “Linkedin Notification from Jay Satalich).

Supervising Transportation Survey (Chief, Office of Surveys) at State of California, Department of Transportation:
“GNSS Leveling Web Application” [is] an Esri ArcGIS online web app created for my “GNSS Leveling” students at College of the Canyons. Designed as a practical tool when planning vertical control surveys using GNSS. National datasets include: National Spatial Reference System (layers: satellite visibility, stability, and vertical control source), geology, and GEOID18 (layers: GEOID18 height, difference between GEOID18 and GEOID12B, and GEOID18 uncertainty). California-specific datasets include: oil/gas/fracking/injection wells, fault lines, oil fields, groundwater basins, and landslide areas. The NOAA National Geodetic Survey data layers were created and published by Brian Shaw. People who influenced development of this app include Dave Zilkoski, Kevin M Kelly, Ken Hudnut, David D Jackson, Ross S. Stein, and Arthur Sylvester.
The box titled “GNSS Leveling Web Application” depicts a map of the Los Angeles area that provides the list of published marks in NGS’ database with an overlay of the uncertainty of NGS’ hybrid geoid model GEOID18. Plotting the published marks from NGS’ database is very useful for surveyors reconning marks for a GNSS survey project. The attributes allow users to quickly identify stations that have published heights from leveling adjustments projects (labeled as ADJUSTED) and those that have heights published from GNSS adjustments projects (labeled as GPS OBS). (See here for definition of attributes.)

As you can see from the list of layers, the web application enables users to select the layers that are pertinent to their survey project requirements. The application is designed for California surveyors but the concept is transferable to other States. For example, the following layers are not just for California surveyors: Arizona water wells, Louisiana oil and gas well, U.S. oil and natural gas wells, Principal Aquifers of the United States, and, of course, all of the NOAA NGS data layers.
One layer that is very important to California users is the layer that provides the fault activity in their region. The box titled “Fault Activity Map of California: Pre-Quaternary and Quaternary Faults – Quaternary Faults” depicts the list of published marks in NGS’ database with an overlay of the fault activity map.

The application also has a feature that lists the marks that were involved in the development of NGS’ hybrid geoid model GEOID18. (see the box titled “GNSS Leveling Web Application GEOID18 GPS on Bench Mark Layer”). Clicking on a mark’s icon provides information and statistics about the mark (see boxes titled “GEOID18 GPS on Bench Mark Layer — PID EW6989” and “Information for GPS on Bench Mark for PID EW6989”). This is one of the layers that provides information for the entire CONUS region. All this information is available from NGS’ website but this application incorporates all of NGS’s data as well as the local information in one application. This web application is very useful to a surveyor planning a survey project and/or providing information to a field reconnaissance team.

Individuals interested in participating in NGS’ GPS on Bench Mark program should register for NGS’ Dec. 10 webinar, which will discuss the status of the program. See the box titled “GPSonBM Transformation Tool Campaign Update — 12 months remaining” for the information on the webinar. Users can register for the webinar here. I would encourage all users to access the web application tool developed by Jay and/or NGS’ website before participating in the next NGS GPS on Bench Mark webinar.
Almost all of my columns have focused on establishing accurate GNSS heights. Most of my 45 years of working in the field of geodesy has been focused on heights; that is, leveling-derived orthometric heights, GNSS-derived orthometric heights, and geoid heights. Gravity is very important to estimating all of these types of heights. Recently, a colleague sent me a video proving Galileo’s famous gravity experiment. It’s an older video (November 2014), but it’s really fascinating. You can see the entire video here. Another individual pointed me toward the same experiment performed on the Moon during the Apollo 15 mission. What’s amazing to me is that over 400 years ago an individual spent time studying the effects of gravity and developing the concept of acceleration due to gravity. I wonder what the world would look like today if Galileo would have just accepted Aristotle’s theory of gravity (which states that objects fall at speed proportional to their mass) and decided to focus on other tasks. Saying that, I am amazed that most geospatial users do not realize the importance of gravity (and physical geodesy) in the development of the geospatial products and services that they use daily; and, how critical it is that more research is required to meet future geospatial needs. The advancements in satellites and computers have enabled geodesy to expand into many different disciplines. Geodetic science and technology now underpin many sciences, large areas of engineering (such as driverless vehicles and drones), navigation, precision agriculture, smart cities, cellular telephones, and location-based services. (See the GPS World First Fix column about the shortage of American geodesists).
When I end one of my presentations, I always emphasize that Geodesy Provides the Foundation for all Geospatial Products and Services, and Integrated and Collaborative Organizations Create Geospatial Solutions. Geodesy is just as important today as it was 400 years ago.
I hope everyone stays safe during this COVID-19 pandemic and enjoys the holidays.
SPH Engineering has partnered with Daewoo Engineering and Construction (E&C). Through the partnership, SPH will support Daewoo’s data management projects through its Atlas artificial intelligence (AI) platform, which enables aerial imagery storage, map creation, change tracking, object detection and territory segmentation.
Photogrammetry data is expected to become one of the key components for storage and processing, SPH added.
According to the companies, Atlas will enable Daewoo Engineering and Construction to set up an online archive of drone imagery and photogrammetry products, track changes and generate reports, automate object detection and measure the identified objects of interest. The platform also will increase data availability for participants of construction workflow.
“Atlas can be definitely used in various fields, but it will be a groundbreaking platform, especially in the field of construction survey,” said Geunmok Song (Alex), digital construction team manager at Daewoo Engineering and Construction.
“When we introduced Atlas back in spring, first of all we wanted to support our existing UgCS customers with an easy-to-use AI tool to store and process data collected with our software integrated to a UAV,” said Alexei Yankelevich, R&D director at SPH Engineering. “We are proud that Daewoo Engineering and Construction, the representative of Korea, has opted for our solution.”
Cobham Aerospace Connectivity has been selected by General Atomics Aeronautical Systems Inc. (GA-ASI) and the U.S. Army to provide the anti-jam GPS systems for the MQ-1C ER Gray Eagle Extended Range (GE-ER) unmanned aircraft system (UAS) platform.
As part of a multi-domain operation equipment suite that is compatible with existing GE-ER aircraft, the DACU-8 capability provides assured positioning, navigation and timing to the Gray Eagle ER UAS, weapons and sensors. According to Cobham, this modification to the Gray Eagle ER UAS ensures the platform can provide reconnaissance, surveillance and target acquisition and attack capability, even in a GPS contested environment.
The digital antenna control unit (DACU) and controlled radiation pattern array antenna system were chosen for their performance in jammed and benign environments, as well as their ability to output direction finding to on-board systems, Cobham said. This direction-finding capability allows the system to perform as a sensor, enabling the platform to identify, locate and respond to the jamming threat.
“GA-ASI and Cobham collaborated very closely on integration activities and on-platform performance evaluations to deliver cutting edge technology for the U.S. Army,” said Matt Cadwell, North America sales director at Cobham. “Cobham is very proud to support GA-ASI’s leadership through the ‘survive, persist and thrive’ evolution in denied environments. The DACU-8 capability ensures GE-ER’s ability to persist in a contested environment, providing critical RSTA capability in a contested environment, supporting the Army, as well as the joint force.”
The U.S. Space-Based Positioning, Navigation and Timing (PNT) Policy tasked the NASA Administrator to develop and provide requirements for the use of GPS and its augmentations to support civil space systems. NASA is exploring the viability and enhancement of GPS and GNSS signals in the Space Service Volume and beyond to support operational U.S. missions and civil space systems. Spirent GNSS solutions and expertise will support testing of the GNSS receivers intended to be deployed in the upcoming lunar exploration, the company said.
“For over two decades, NASA and other space users have selected us to provide leading-edge test and development solutions for missions ranging from short suborbital flights to weeks-long orbits beyond geosynchronous altitudes,” said Ellen Hall, president at Spirent Federal Systems. “Working collaboratively with our customers enables us to meet their demanding test and development needs with the trusted solutions for which Spirent is known.”
