To find out what is going on inside high-precision GNSS “rovers”, I interviewed GNSS manufacturers. While there are many different approaches, there are common elements, and a kind of “dominant design.” That these instruments can deliver cm precisions often seems like a bit of magic, but I hope this three part series helps demystify it—users feel more confident about these “magic boxes” if they know more about how they work.

Desert Botanical Garden (DBG) in Aarizona is one of my favourite places to visit. An extensive and beautiful collection fo desert flora from all over the world. Read how DBG bilt a digital twin with high precision GNSS and GIS. Honored to have been able to help put together this case study.

It recently test drove a flexible and precise GNSS field mapping system. It has three GNSS receiver/antenna options, field mapping software, 3rd party mapping software support, survey-grade precision, and some features that (as far as I can tell) are unique to the industry. https://gogeomatics.ca/zeno-test-rrive/ #gnss #AssetMapping #GPS #GIS #surveylife

Does #EUSpace come to mind if you think about archaeology? Well, it should!

Earth Observation & #GNSS are key to protecting and preserving our cultural heritage thanks to accurate positioning tools to locate the sites & EO monitoring of the land to preserve the excavations.

Free and global; 10cm-20cm positioning in real-time. This is the potential for the Galileo High Accuracy Service (HAS). While not survey grade precision, this provides a highly valuable option for GIS and asset field mapping. While still in beta, the early results look promising. #gnss #galileo #mapping #GIS Cover story in xyHt Magazine https://www.xyht.com/gnsslocation-tech/has-potential/

It was only 5 years ago when no-calibration (GNSS+IMU) tilt compensation for surveying and constuction rovers first hit the market. And now, it is an almost universal feature for new rovers. I spent some time looking at the adoption and impact of this technology; when users recommend to use it, and when not to.

Oh, and that 'click-baitey' title on the magazine cover was not my idea 🙄

No autonomous free-for-all on all roads and highways any time soon, but there are present day AV applications that can and are being implemented. There is a growing market for defined zone applications.

Mapping Planet Earth For Better Positioning - ESA’s GENESIS Mission

https://www.esa.int/Applications/Navigation/Mapping_planet_Earth_for_better_positioning_ESA_s_GENESIS_mission <-- shared article
“ESA’s Navigation Directorate is planning a new satellite whose results will enable the generation of an updated global model of Earth – the International Terrestrial Reference Frame, employed for everything from land surveying to measuring sea level rise – with an accuracy down to 1 mm, while tracking ground motion of just 0.1 mm per year. This improvement, at a stroke, will have a major impact in multiple Navigation and Earth Science applications, including an enhancement on the precision of the Galileo navigation system. This mission, called GENESIS, is being proposed to ESA’s Council of Ministers in November 2022…”
