An NCOM decoder based in C for use with OxTS navigation systems, enabling users to decode the binary NCOM output.
This folder contains two library files NcomRxC.h and NcomRxC.c, which can be included in your project.
The folder contains a simple program that exports an NCOM file to a CSV file, using the library files in nav. The program opens a file stream (to read the file), and decodes the NCOM packets from this stream.
NB: This has been tested on the following platforms:
- Unix (MacOS)
- MINGW64 (Windows 10)
Please note there appears to be an issue running in Cygwin.
# First clone this repository
git clone https://github.com/OxfordTechnicalSolutions/NCOMdecoder.git
cd NCOMdecoder
# Change directory into example source code folder
cd example
# Run make, which includes library files in nav (specified in Makefile)
make
# Run executable, with example ncom data to create csv file
# Usage: NcomToCsv <input file> <output file> [<trig_file>]
./NcomToCsv 171019_031603.ncom 171019_031603.csv
The following table lists all the measurements available in a standard NCOM packet.
These can also be found in measurements.csv
