The exit row is awesome for leg room but terrible for attracting arm rest dominators.

Really enjoying being back in DC for a bit. Such a great city and fun seeing it so vibrant and active. Also so many cool map people to catch up with #GeoDC

Got my ticket for NORTH51 Conference and excited to get back to hanging with awesome geo-peoples and enjoying the Canadien Rockies 🎉. Come join the fun!

It was a ton of fun having a deep dive conversation with Daniel about GPS. There are a few hot takes on correction services and unit economics. If you get a chance check it out.

We've had a few questions about our testing results from the MapScaping episode. The short version, we use SparkFun Electronics RTK units as ground truth and mount test phones with vertically aligned antennas 31cm above each receiver. Then we run a variety of static and kinematic scenarios

Let the vehicular testing begin!!

When I was cross posting about ChatGPT knowing about Null Island an academic shared they'd written a whole peer reviewed article in IEEE about Null Island. Super fun to read! ieeexplore.ieee.org/document/98522…

Really appreciate the opportunity from @geoworldmedia to talk about the future of GNSS and the geopolitical backdrop helping driving it.

Vertical "Z" error is often the ignored sibling for the accuracy of GPS. We discuss vertical accuracy improvements with collaborative positioning. Continuing our quest for a resilient GPS network without new chips, satellites or terrestrial infrastructure medium.com/@zephr.xyz/squ…

Tons of fun talking with Mojtaba. Thanks for the opportunity to share the team's work!

This was a ton of fun. Jed is an amazing host. Stick around for the discussion of OSM as the Fremen of mapping.

Thanks to SpaceNews for letting us share the team's thoughts on jamming and spoofing. We've been doing a good bit testing in Ukraine and Israel in the last few months. The level of sophistication and power of EW attacks on GNSS are hard to overstate. spacenews.com/global-navigat…

Someone add geospatial coordinates to all this hotness already

Landing in SLC for #SOTM, and it is appropriate that the in-flight map would be OpenStreetMap. With the default styling no less. Definitely a cartographer business opportunity.

I'm open to new projects! With 15+ years as a Geospatial Consultant / Specialist, and experience in marketing geospatial products, I’m looking for new opportunities. If you need expertise in these areas or know someone who does, DMs are open. 😊 Please share if you can!

Impressive fast work by the Microsoft Azure and NASA VEDA teams to present a vision for an Earth Copilot

Thought I'd drop back into Twitter to share some open data. You can take or leave the perspective on building more accessible AR enablement. Geographers can't trying to make everything raster or vector 😂medium.com/@zephr.xyz/the…
