GPS Tools ========= *by Hauke Daempfling <haukex@zero-g.net> at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), Berlin, Germany, <http://www.igb-berlin.de/> (legal information below)* This is a collection of various tools for __logging and parsing GPS NMEA data__ as well as (despite the name of the project) __general and device-specific data logging tools__, especially for use with a __Raspberry Pi__. It is by no means a complete application, but its individual parts do work and can hopefully be useful. Featuring: * A general-purpose serial logging daemon with USB hot-plugging support * Instructions on how to build a standalone NTP server synchronized to GPS * Miscellaneous tools and information on getting things running on a [Raspberry Pi](http://www.raspberrypi.org/) The scripts are written in [Perl](http://www.perl.org/) (at least v5.10 but a current version is *strongly* recommended!) and are intended for use on \*NIX systems (some scripts may work on Windows but that is untested). These tools currently live at <https://bitbucket.org/haukex/hgpstools/>. There is also an issue tracker there. In general, you can get each tool's documentation via `perldoc <filename>`. In a few places, not every configuration option is documented, and you may still need to have a look at the code. The following gives some starting points, but note this list is not complete, have a look around this repository to discover all the available scripts. * **`INSTALL-RPi.md`** Instructions on how to set up the serial logging daemon (mentioned below) on a Raspberry Pi, including general-purpose instructions on doing the initial setup of a Raspberry Pi. * **`RPi3_Adafruit-GPS_NTP-chrony.md`** Instructions and tools to build a standalone GPS-synchronized NTP server with a Raspberry Pi 3, an Adafruit "GPS Hat", and `chrony`. * **`ngserlog.pl`** and the `serloggers/*` scripts A generic serial port logger with support for hot-plugging USB/RS232 adapters. In combination with a configuration script such as `ngserlog_nmea.pl`, it processes NMEA data, and can be run as a daemon. Various other loggers have been added as well, and those configurations can be copied and adapted to log other kinds of data.
