[F&E]: Calculate ionospheric TEC

[gofrito]

Description:

We use pypride (orig. code) to retrieve the ionospheric TEC based on the location of our antennas and uplink ground stations. We used the class ion: in classes.py

class ion(object):
"""
Class containing ionospheric TEC-maps
"""
We retrieved these two variables:

• UT_tec: list = iono.UT_tec
• fVTEC: list = iono.fVTEC

Can we use a similar call to the new pride class to retrieve the ionospheric maps and calculate the TEC?

Suggestions for implementation:

No response

Sorry, I missed the notification for the issue!

We have io.IonexInterface, which is an interface for ionex files. As of 1.2.10, you give it the path to an ionex file, and it can give you a list of regular grid interpolators for all the TEC maps it includes. I was a little bit confused about it not giving you the UTC epochs of the maps, so I went to the implementation of the ionospheric delay and I found a bug #19

I will fix this bug so that, instead of returning a list of grid interpolators, the read_data_from_ionex_file function returns a dictionary with the epochs of the TEC maps as keys, and the regular grid interpolators as values.

About this question: if you are just interested into calculating the TEC for a station, you can load an ionex file with IonexInterface, get the grid interpolator for your epoch of interest, and evaluate it at the coordinates of your station. That will give you the vertical TEC.
