The U.S. Space Force aims to better pinpoint the location of Earth’s true center using lasers on GPS satellites slated to launch in 2025. A set of laser retroreflector arrays, or LRAs, will be installed onto two GPS III satellites, called SV9 and SV10, as part of NASA’s Space Geodesy Program space sensor network. The ...

The Earth’s spin axis is not constant. It moves slowly over time relative to the Earth’s crust. This is caused by various processes on the surface and inside the Earth, such as the melting of ice masses or the uplift of land masses, as well as mass shifts in the Earth’s viscous mantle and core. ...

Along with providing stable navigation services worldwide, the Beidou global satellite navigation system developed by China has been monitoring the deformation of Lake Sarez in the seismically active zone of the Pamir Plateau in eastern Tajikistan for nearly three years, predicting potential earthquakes. “Forty donkeys, 10 scientists and 30 others spent 10 days transporting the ...

In order to maintain consistency with the International Earth Rotation and Reference System Service (IERS) and the International GNSS Service (IGS) reference frames, NGS has been working to implement the new International Terrestrial Reference Frame 2020 (ITRF2020) and IGS20 realizations in the U.S. National Spatial Reference System (NSRS). This will result in updated North American ...

Nie trzeba wcale lecieć w Kosmos, żeby badać jonosferę. Marek Czołpiński, student z Wydziału Geoinżynierii UWM za badania nad jonosferą otrzymał nagrodę w konkursie organizowanym przez Stowarzyszenie Geodetów Polskich oraz Główny Urząd Geodezji i Kartografii. „Analiza gęstości elektronów na wysokości orbity Swarm w kontekście sejsmicznych zaburzeń jonosferycznych” to tytuł pracy inżynierskiej, za którą Marek Czołpiński ...

Satellite Laser Ranging (SLR) is a very precise, laser-based method for determining the distance between a satellite and Earth with an accuracy of a few millimetres. SLR is primarily used in geodesy. This is because the precise measurement of satellite orbits helps to determine changes in Earth’s structure and rotation. The SLR method also makes ...

New maps have revealed a hidden hydrothermal system beneath a legendary lake in New Zealand. The Rotorua area is well known for hydrothermal activity, with the Tourism New Zealand website stating that clouds of steam drift around the lake’s shore, and that sulfur gives a “magical green-blue” color to the water. Researchers at GNS Science, ...

Geovation, Ordnance Survey’s (OS) award-winning open innovation hub, has opened nominations for round two of its Geospatial Innovation Awards to showcase the best in geospatial innovation and the impact it has on people, places and planet. The 2024 awards, which are open to international entries, build on the success of the inaugural awards earlier this ...

Oregon State University will receive $6.5 million in federal funding over a five-year period for research related to updating the National Spatial Reference System, a coordinate system that defines geographical elements ranging from longitude and latitude to height and orientation, the college said. OSU officials said common uses for the NSRS include surveying and mapping ...

A new scientific technique could significantly improve the reference frames that millions of people rely upon each day when using GPS navigation services, according to a recently published article in Radio Science.

Gravitational acceleration measurements were conducted in the Allgäu region of southern Germany by the Federal Agency for Cartography and Geodesy (BKG) in September this year. In high-altitude locations, helicopters were utilized to access the measurement points. These measurements play a crucial role in enhancing altitude determination through satellite-based methods such as GNSS. The elevations derived ...

Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth of a percent. The technique could help scientists understand the complex flows of water and air that cause the tiniest of tweaks to the planet’s spin. Earth’s rotation isn’t perfectly steady. The planet speeds up and slows down as ...

While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists at the University of Bonn have come up with ...

Naukowcy z Wojskowej Akademii Technicznej zaproponowali innowacyjną metodę pomiaru ubożenia wód podziemnych opartą na pomiarach GPS. To, jak zmienia się poziom wód podziemnych, będzie można monitorować zdalnie – nawet w najbardziej odległych częściach świata. Mimo że techniki teledetekcyjne się rozwijają, a obserwacje naziemne stają się coraz dokładniejsze, modele opisujące poziom wód gruntowych nadal nie są ...

“We need to use an external frame of reference when making measurements of the Earth’s position, tilt and speed of rotation, and that these supermassive black holes are our best indicator as they don’t really move.” These measurements, called Earth Orientation Parameters, are used by Global Navigation Satellite System (GNSS) satellites to help geodesists understand ...

Landslides and rockfalls are increasingly becoming a real threat to people and infrastructure in light of the changing climate and the associated changes in soil and rock structure. The more precise the measurement, the earlier hazards can be detected, and consequently damage can be limited or even avoided altogether. A team at the Institute of ...

There’s a massive “hole” in the Indian Ocean, researchers say—but it’s not the kind that could drain away all that water. Instead it’s a term geologists use to describe a spot where Earth’s gravity is lower than average. And a new study may have finally revealed its origins: it appears to be caused by plumes ...

Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground for the first time. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver, researchers at the University of Tokyo were able to calculate the receiver’s position in the basement of a six-story building. As GPS cannot penetrate rock or water, this ...
