I do all three.
G5 GPS Navigator providing GPS location data to:
1) TMD-700 dual band two meter / four forty radio. Doesn't count on the
internet being in range.
2) Laptop using G5 GPS data for an aprs program to broadcast info via
internet, and for monitoring
APRS activity of my system. Cell phone provides internet and doesnt
count on relay via RF using ham radio.
Android sourced GPS
3) Android phone running APRS with GPS on and active. Incoming cell
phone may interrupt feed to laptop,
but auto resumes when call is disconnected.
When mobile from North West Indiana to middle Tennessee, it is not
unusual for one or two of the three options not to be performing due to
GPS signal loss, or cell phone tower signal loss. Most of the time one
or more is functioning.
All Lat / Long info from any source has the last two digits truncated.
This way the true location is off by a couple miles and helps reduce
theft while stationary during pit stops etc etc . But it is more than
good enough for family and friends tracking my trips.
Would suggest being APRS operational via a radio, and a android cell
phone if you want fairly constant coverage. At times, all those methods
will still have gaps.
Have considered using HF for APRS feed, but haven't got a round to it yet.
While those systems are active, I operate HF voice and enjoy qso's while
on the go. Using Kenwoods SkyCommand mode, I also enjoy using my HT to
operate the HF system in the mobile or at the base. It is KooL to let
the person on the other end on HF that you are on an HT and walking
