On longer trips, I use a Garmin InReach GPS tracker. This uploads location every 2 minutes via satellite, and can also be used for two-way messaging.
You can visit the tracker using the following link, or view it on the map below.
You might notice that the position claimed by the tracker occasionally jumps hundreds of miles back to a previous position. This is a bug from Garmin that, 4 years on, they don’t seem to have any intention to fix.
