Simple utility that writes NMEA (GPS) sentences to a file, which can then be played back later using a simulator utility.
Installation
[sudo] npm install -g nmea-gps-logger
Usage
gpslogger -o ./output_dir/ -b 57600 /dev/tty.GNS1000-GPS
# Usage: gpslogger [-v | --verbose] [-o | --output <output_dir>] <serial port address>

# Hint: on most POSIX systems, you can get a list of connected serial devices by running: ls /dev/tty*
