TDoA - Time difference of arrival

Inputs:

1. wav files with GNSS timestamps from KiwiSDRs which are generated by kiwiclient
2. positions of the used KiwiSDRs. This information is stored in the directory gnss_pos and put there by kiwirecorder.py

Prerequisites

• This code should work on linux and on OSX
• Install octave (>=4.2.2) + signal package: in octave: pkg install -forge signal

Download / Installation

• Initial checkout: git clone --recursive https://github.com/hcab14/TDoA.git
• Update to latest master branch: git pull --recurse-submodules
• For now everything is contained in the git repository, i.e., nothing is installed in /usr etc.

Running the example octave script

• in octave: [tdoa,input]=proc_tdoa_DCF77;
• this should produce two files in the png subdirectory
