Weight: 1.3 oz., (38 g), not including interface cable or remote antenna

  • Operating temperature: -30C to +85C (internal temperature)
  • Storage temperature: -40C to +90C

Typical current draw: 115 mA typical @ 5.0 VDC

 

This is the GPS we will include on our balloon.  It's lightweight, and sits inside of our payload capsule while we run the GPS antenna to the outside of the box.

There are multiple models of the GPS 25.

Which model you choose depends on what voltage you want to use and which features you need.

Pros

Lightweight because it's just the GPS circuit board. No LCD.

Takes anywhere from 3.6-6 VDC unregulated

Cons

Hard to tell if and when it's working because their is no LCD.

Doesn't have a built in antenna. So you need to include a trailing antenna unlike the GPS 35 models
