GPS-simualtor

GPS simulator, that takes a path in form of a csv file and outputs NMEA messages accordingly on a serial port. Built to aid high alititude baloons hardware tests. This website can generate flight data file compatible with the simulator.

Prerequisites

You need Python 3 to run this scipt, dependencies are listed in the requirements.txt file. You can install the with pip3 install -r requirements.txt.

Usage

You can run the scipt with Python or directly as an executable if your system matches the shebang path.

python3 -m gps_simulator.py [-h] [-b BAUDRATE] [-t TTY] [-f FREQUENCY] [-d] [-V] flight_path_file

Positional arguments:

• flight_path_file path to the flight path csv file, the columns has to be: unix_timestamp, latitude, longitude altitude, (in ISO 6709 string Annex H format) without coulumns headers.

Optional arguments:

• -h, --help show this help message and exit
• -b BAUDRATE, --baudrate BAUDRATE output serial baudrate (bps)
• -t TTY, --tty TTY file path for desired usb tty output
• -f FREQUENCY, --frequency FREQUENCY frequency of simulated NMEA messages (Hz)
• -d, --dump dump NMEA messages to file instead of sending them to serial
• -V, --verbose print NMEA messages to screen before sending
