Re: [Talk-us] Website showing the best time to survey with GPS.

[Mateusz Konieczny]

Note that for a typical GPS, especially GPS in smartphone I would expect that
this effects will be not really noticeable in affecting accuracy.

Maybe except massive solar storms like
https://en.wikipedia.org/wiki/Solar_storm_of_1859

I tried to check sources, but quick search found nothing really good, except 
some things
like
https://www.utdallas.edu/news/2013/5/16-23761_Solar-Flares-May-Interrupt-GPS-Navigation-Research_article-wide.html
 

"If a flare is particularly large, the resulting turbulence in our upper 
atmosphere 
could disrupt radio signals and GPS navigation, for example."

what seems to confirm that you need really unusual activity to have results.

[Talk-us] Website showing the best time to survey with GPS.

[Eric H. Christensen via Talk-us]

I was told there was a website that forecasted the best times to do survey work 
with GNSS based upon diversity of satellites in the sky, solar activity, etc. 
Does anyone know what site this is?

Thanks,

[Talk-us] Next Mappy Hour July 10!

[Martijn van Exel]

Hi all,
The next OSM US Virtual Mappy Hour will be on July 10 at 6pm PT / 9pm ET!
As always the Mappy Hour is a great place to catch up with your fellow mappers, 
and learn something new. 
I am always looking for volunteers to do a 5 minute presentation on something 
they are working on. This can be a personal mapping project, a local mapping 
group update, something interesting going on at your company.. As long as it's 
OSM related!
See the OSM wiki for more details on how to join -->

See you then!
