Using laser-guided imaging to peer through dense jungle forests, Tulane University researchers have uncovered vast unexplored Maya settlements in Mexico and a better understanding of the ancient civilization’s extent and complexity.
The new research, published in the journal Antiquity, was led by Tulane University anthropology doctoral student Luke Auld-Thomas and his advisor, Professor Marcello A. Canuto.
The team used lidar, a laser-based …

Aerodata AG has announced that it has been granted a Supplemental Type Certificate (STC) by the European Union Aviation Safety Agency (EASA) for its advanced GPS Anti-Jamming and Anti-Spoofing solution. This certification applies to installations integrated with Garmin 5000 avionics in a Cessna® Citation Latitude® jet.
With the growing threat of GPS jamming and spoofing in both civil and military aviation, Aerodata has developed a robust solution to ensure continuous GPS availability. As attacks on GPS systems continue to increase, this Anti-Jamming and Anti-Spoofing technology is crucial in maintaining safe and …

ArkEdge Space, a Japanese space start-up based in Tokyo, providing comprehensive solutions from planning and design to mass production and operation of small satellite constellations, has been selected by the Japan Aerospace Exploration Agency (JAXA) as the project provider for the Feasibility Study (Part 1) on the Low Earth Orbit PNT (Position, Navigation, Timing) System (LEO-PNT) to be conducted by JAXA. The project commenced on the 11th of October, 2024.

LEO-PNT is a constellation of small satellites, orbiting at an altitude of 900-1,200 km. This is lower than the conventional Global …

The objective of this study is to create a new platform for the automated detection of irregularly shaped man-made marine objects (ISMMMOs) in large datasets derived from marine aerial survey imagery. Readers may recall that we published the first part of the paper in October issue. We present here the concluding part
