Closed MrBourriz closed 1 year ago

MrBourriz commented 1 year ago

1-plots the satellite skyplot using precise ephemerids sp3, it's possible? 2- How to read sp3 files.

Thanks for your questions. While some SP3 functionality currently exists with a tutorial here, I would suggest waiting for version 0.2.0 to be released which greatly simplifies how to answer your questions.

Both questions will be easy and possible once #127 and #130 are pulled into main and we release gnss_lib_py v0.2.0. Once those pull requests are merged in, I'll comment on this issue pointing you towards the relevant SP3 tutorial. Those changes should happen in less than a week.

Please make sure that you've updated to version 0.2.0 of gnss-lib-py that we've recently released.

  1. The ephemeris downloader tutorial shows an example of how to download an SP3 file based on a specific date/time and then how to visualize that information using plot_skyplot.
  2. We added an SP3 tutorial on how to read sp3 files using glp.Sp3().

I'm closing this issue now thanks to the additional functionality we released in version 0.2.0, but feel free to post any questions/problems you have using the new sp3 functions.
