The reason to run it on a Mac laptop is to make the signal available to programs needing time and location services in a way that is flexible and device independent.

I use virtual machines, so I should be able to let a program running on any virtual machine connect to the gpsd host running on the Mac.

In my case on my Mac, I will be plugging in usb devices or possibly using a bluetooth connection. I already know I can listen to BT devices using things that appear on ports /dev/tty.BT* when the devices are paired with the Mac so I won't go into that here.

To get the DeLorme LT40 going I seem to need gpsd-emul (emul = Earthmate userland). Trying to ./configure that, it tells me I need libemul. That's in the separate emul tarball. They are on the berlios.de site.
emul:

Now that the dependencies are out of the way...
At version 2.94, gpsd builds out of the box on Snow Leopard.
unpack tarball

Where

I will be running gpsd in a docker container on Bellman to set up my Magnavox reference station.

gpsd home: http://gpsd.berlios.de/

I used to have extensive instructions on how to set up gpsd on an old Mac Book Pro. Now the instructions look like this, for now anyway. 

docker pull forcedinductionz/docker-gpsd
docker run -it -p 2947:2947 --device=/dev/ttyAMA0 forcedinductionz/docker-gpsd -D2 /dev/ttyAMA0

By using docker I avoid installation issues of getting it going on a Mac. I still have to configure it. Not able to do that at the moment. (My GPS receiver is packed in a box.)

What and why

gpsd is a service that listens to one or more gps receivers and makes the received data available over a network connection. It understands a wide variety of binary protocols.

Receivers

All the receivers I have currently are covered:

  • DeLorme Earthmate
  • Garmin
  • NMEA
  • SiRF
  • Trimble TSIP
  • UBX

What you get

Besides the daemon "gpsd", of course...

In /usr/local/bin, you will find

  • lcdgps
  • gpxlogger
  • gpspipe
  • gpsmon
  • gpsdecode
  • gpsctl
  • cgps

Position

Time

Python integration

I need to put a short python script here...
