The code that I wrote using Python's gpsd library takes approximately between 0.1 and 1 seconds to collect a data packet. I am working on a fix so that we can collect data from the stream much faster.
That does appear a bit slow, indeed.

Instead of gpsd, the Python libraries pynmea2 and serial seem to work for our purposes with very few lines of code.
I felt gpsd was a massive overkill for.our purposes, so this is cool. I'll take a look tomorrow.

Although the GNSS receiver receives a bunch of data, not much of that data is useful for us. According to my tests it only receives a timestamp 3 times per second, and it only receives location data 1 time per second. This is consistent with various online sources.
Description
The requirements for the GPS receiver are in the following issues:
The work is in the coloradocube/balloonsat/gps directory.
