What have we learned about BeiDou from new laser observations?

29-04-2024

Recent enhancements in global satellite navigation have taken a significant leap forward thanks to the International Laser Ranging Service (ILRS), which now tracks an additional 20 BeiDou-3 satellites orbiting the Earth. This expansion from the initial four satellites under surveillance marks a major milestone for the BeiDou Satellite Navigation System (BDS), a critical component of the global navigation structure alongside GPS and Galileo.

Our team at the Associated ILRS Analysis Center has detailed these advancements in a new study, "Satellite Laser Ranging to BeiDou-3 Satellites: Initial Performance and Contribution to Orbit Model Improvement" by Zajdel et al., 2024. You can read more about the study here: GPS Solutions, Volume 28, 100 (2024). LINK

Analysis of the performance of various GNSS positioning concepts dedicated to precision agriculture

02-04-2024

Automated guidance systems for precision agriculture rely on GNSS and correction services to achieve high accuracy and precision during field operations. The study evaluated the performance of selected GNSS positioning services for precision agriculture in a field experiment. Three correction services were used: SF1, SF3 and RTK, which apply different positioning concepts, i.e. WADGNSS, PPP, and RTK, respectively. The tractor was autonomously steered along several defined paths in open-sky areas as well as near heavy tree cover. The vehicles reference route was determined using a robotic total station.
