Rendezvous has multiple tracking systems aboard. Most of them are on all the time, but some only really show useful information when I am on a trip.
Automatic Identification System
Automatic Identification System (AIS) is a VHF radio based broadcast system that allows individual boats to share their location with base stations. I am a mobile base station myself, and gather data from other boats within my antenna range.
AIS requires a base station with an internet connection to work reliably. If my internet connection is not reliable, then I rely on a base station somewhere else picking up my VHF broadcasts. As a result, this position may not be 100% accurate or current – check the time stamp.
I use a Garmin inReach Explorer+ while on longer trips. This sends out tracking data every 10 minutes using satellites, so it works just about anywhere.

The FloatHub device lives on board Rendezvous and uses its own internal GPS to track my location, along with local AIS data about the boats around me.
