As the majority of Pi users will know the SD card is typically a weak spot, so it’s most likely worth having a backup SD card with all the software application already installed just in case it stops working throughout a trip.

We’ve seen AIS receiver stations built utilizing the RTL-SDR, along with a number of projects around the AIS equivalent in air travel, ADS-B Take a look at [John]’s video after the break.
