Having worked on gps chipsets, one of the corrections that need to be applied is for relativistic effects,those calculations are happening in every GPS chipset as it needs to iterate down to a very precise position estimation of the satellites in order to produce an estimation of your position.
There is no magic involved, relativity/time-dilation is not a disputed effect.
As an example, clone https://github.com/gnss-sdr/gnss-sdr https://github.com/gnss-sdr/gnss-sdr
and search for "relativistic correction"
- nyc111 8y agoThanks, but I don't know how to do this. Is there a way I can see the code without cloning?
- sokoloff 8y agoGo to that github URL, click on the green "Clone or Download" button and download a zip file of the code. Unzip and search away.
