🚀Two new Galileo satellites were launched into orbit, marking another successful mission in the collaboration between the European Commission, EUSPA - EU Agency for the Space Programme and European Space Agency - ESA and other numerous European entities in the space sector. 🛰️Galileo, the EU´s Global Navigation Satellite System (GNSS), provides improved navigation, positioning and timing information, designed to enable various satellite-based services and applications for a broad spectrum of sectors and users, ranging from: 🛫 aviation and 🌊 maritime to 🌱 agriculture and 📍location-based services. 💡Explore how #GNSS data are used to monitor and identify illegal fishing and environmental crimes at sea in our Success Story 👇 https://lnkd.in/e8MvX6xw #EUSpace 👇 https://lnkd.in/e3yPdd_g

On March 8, I spotted an unidentified ("UNID") geosynchronous object at longitude 33.8 E near PAN/NEMESIS-1 and EUTELSAT HOT BIRD 13B. It was not there 4 days earlier. The UNID likely is a commercial geosynchronous satellite that has just been relocated without the 18th STS having caught on to it yet. Or it could be something new. For now, it is unidentified. Imagery in this blogpost here: https://lnkd.in/eHHyDrfh UPDATE [CORRECTED]: I believe it is possible that the UNID could be the newly launched Chinese satellite WHG-01 (2024-040A). It was launched on 29 February. It could have been inserted into GEO at 33.8 E on March 6 near 11 UTC, a week after launch.

https://lnkd.in/gdY2qCqq The Philippines is being considered as a possible location for the next United States Geological Survey (USGS) Landsat ground station, the State Department has announced. The USGS has ground stations in South Dakota and Alaska, as well as Norway, Germany, and Australia. These locations serve as the primary data capture and Telemetry, Tracking, and Control (TT&C) facilities for the USGS Landsat satellite missions. We are looking at cooperation in all areas including satellite surveillance systems and yes Landsat ground station. The two states also tackled the potential for “expanded cooperation” on the use of space for maritime domain awareness. SeaVision is a web-based tool that uses satellite imagery, transponders, and infrared to track ships round the clock, providing near real-time and historical information on vessel positions and details, i.e., owner, operator, and port visit history. Such programs can help monitor and document vessels in the Philippines’ territorial waters and Exclusive Economic Zone. The Department of Foreign Affairs said the US has been providing free access to the system since 2021, which is presently being used by the Philippine Coast Guard, the Philippine Navy, Bureau of Fisheries and Aquatic Resources, and the National Coast Watch Center. The Philippines, in the same dialogue, said it is considering to sign on to the Artemis Accords, which establish guidelines to ensure safety and responsible behavior in outer space as countries explore the Moon and beyond. The two countries also agreed to stay in close communication on expanding commercial space ties and space situational awareness.

Fascinating update on what lies beneath the 🌊 in dumpsites off SoCal. Read on for important history we must learn from as we confront #plastic and #chemical threats to #oceanhealth and #humanhealth. “There is no away”.

Photogrammetry is based on the acquisition of two or more images taken from different angles, known as stereoscopy. It is similar to human perception of relief. We can define it as a method in which quantitative information, such as surface elevation, is retrieved from stereoscopic images. Such images are available from ground measurement campaigns, airborne campaigns, or satellite missions. #photogrammetry #stereoscopy #stereoscopic #images #MappingYourWay
