Release notes from gnss_lib_py

v1.0.4

2025-04-08T06:11:48Z

Updates to keep the library up-to-date and compatible with Google Colab.

Version Changelog:

dependency updates
speeding up parsing of NMEA logs (thanks @sandroklarer-pingpong)

v1.0.3

2024-08-27T01:03:20Z

In line with user requests, we are now updating our GNSS library to support Python 3.12! The library is still compatible with Python 3.9, 3.10, and 3.11 across Linux, MacOS, Windows, and Google Colab (Python 3.10). But, if you wish to continue using Python 3.8, we recommend that you stay with v1.0.2.

Version Changelog:

Added compatibility for Python 3.12 and removes compatibility for Python 3.8, addressing #164
Updated functions in gnss_lib_py to enable Python 3.12 compatibility
Expanded tutorials and documentation throughout

I hope you all enjoy the new release!

v1.0.2

Version Changelog:

Convert elevation and azimuth to ENU unit vectors
Compute DOP for NavDatas with elevation and azimuth data
Patched bug where NavData and Visualizations modules were not in ReadTheDocs.
Removes NaN rows that georinex outputs when parsing Rinex Nav data files
Fixes #155
unifies the conftest.py testing file for all modules
checks for NaN pseudoranges in EKF

adds test for returning NaN values in an int array

v1.0.1

2024-01-29T23:04:57Z

Minor bug fix:

Fixes initialization of num_cols when NavData is initialized.

Related updates made to docs and tests

v1.0.0

2024-01-19T22:49:38Z

We are finally releasing version 1.0.0! This release changes file and directory structure to improve the longevity of the codebase and allow for continued expansion of its capabilities.

No significant changes will need to be made in code for users using the import gnss_lib_py as glp convention except for the instances of the concat, sort, loop_time, interpolate, and find_wildcard_indexes functions which used to be class functions of NavData but are now independent functions with the first argument being the navdata object(s) on which to perform the action.

Detailed Changelog

breaks navdata into navdata and operations
rewrites concat, sort, loop_time, interpolate, find_wildcard_indexes so their independent functions and not class functions
adds concat ability to concatenate an arbitrary number of NavData instances rather than just two
breaks out components of visualizations into independent files
updates ReadMe, etc. with updated directory structure
creates uniform tutorial structure with a notebook file at least for each file in gnss_lib_py
updates python packages

v0.2.3

2024-01-11T05:58:34Z

This release mainly expands robustness of the automatic ephemeris downloader, extends compatibility of the rinex_obs parser to all observation codes, and adds parsers for raw android data.

Ephemeris Downloader

Expands file download options to enable downloads for:

rinex_nav: present - Jan 1, 2013
sp3 : present - May 24, 2012
clk : present - Oct 14, 2012
Also adds secondary sources for WUM0MGXFIN clk, wum clk, and BRDM00DLR_R rinex nav for outlier days when those files weren't uploaded to CDDIS

Rinex Observation Files

allows rinex_obs to load all possible observation codes
z-tracking observations may have empty carrier_phase and raw_doppler_hz rows
fixes #139

Android Raw Files

differentiates the Google Smartphone Decimeter Challenge into google_decimeter.py and GNSSLogger parsers into android.py
updates unit_test directories according to the above change
adds parsers for data obtained from the GNSSLogger Android app includingRaw, Fix and all sensors
adds recommended filters for raw GNSS data from android phones
adds new NavData classes for the 2023 version of the Google Smartphone Decimeter Challenge
