Smartphone decimeter challenge

Matlab package for the Google Smartphone Decimeter Challenge at ION GNSS+ 2021.

This project was part of my Master's Thesis at ENAC (École Nationale de l'Aviation Civile). The thesis report and presentation can be found in master_thesis and the paper can be downloaded here.

Installation

This code uses the following external packages:

• Submodules
  • EKF (private)
  • INS (private)
  • magnitude (private)
  • android-measurements
  • gps-measurement-tools/NmeaUtils
• Yet not supported
  • Orekit. See this tutorial on how to integrate Orekit within MATLAB.

Usage

• Make sure you have the input data saved in your workspace with the following structure:

Observations:   {workspace_path}/data/sdc-data/{train or test}/{campaign_name}/{phone_name}_GnssLog.txt
Groundtruth:    {workspace_path}/data/sdc-data/train/{campaign_name}/SPAN_{phone_name}_10Hz.nmea
Navigation:     {workspace_path}/data/sdc-data/brdc/{campaign_name}/BRDC00WRD_R_{datetime}_01D_GN.rnx
Verizon OSR:    {workspace_path}/data/sdc-data/corrections/Verizon/OSR/{campaign_name}/{OSR_filename}.rnx
SwiftNav OSR:   {workspace_path}/data/sdc-data/corrections/SwiftNav/OSR/{OSR_filename}.obs

⚠️   Make sure to have the OSR RINEX files in version 3.03 or above.

• Set your workspace as the parent directory that contains this project. Your workspace should look like the following:

/some/directory/
        |-- data/
                |-- sdc-data/
                        |-- brdc
                        |-- corrections
                        |-- train
                        |-- test
        |-- smartphone-decimeter-challenge/

• Select the desired configuration in the class Config.
• Run main.
