This is the GPS we used to use on our secondary communication payload. It's lightweight, waterproof and durable.
There are multiple models of the GPS 35.
We went for the HVS ($189) model because the bare wire ends
allow you to solder on what you want (i.e. plugs, power adapters.)
We no longer use it because the Garmin 18 is lighter by almost
50% (the weights claimed by Garmin are not correct).
Has a built in antenna. So you don't need to include a trailing antenna like you do with the GPS 25 models.
Lightweight because it's just the GPS circuit board and an antenna. No LCD or battery.
Takes anywhere from 3.6-6 VDC unregulated
Hard to tell if and when it's working because their is no LCD.
