I would like to see more modifications of the Garmin astro that people have made to make it fit in a rocket.
There was a pretty extensive article about this by Mike Konshak in a recent Sport Rocketry. Typically it involves removing the case and using a different method to connect the antenna (hardwire or right-angle SMA IIRC.) Or maybe that was a 54mm, I don't recall.I've heard that it's possible to fit one in a 38mm rocket. Does anyone have details?

Here's what I did:
Not much as I was putting it in the nose cone that has a 2.78" coupler tube that a hair over 18" long. You can see the nose cone standing next to it on the floor.

JD:
Nice work. Do you think your layout can fit in a 38mm tube? The Garmin specs page says:
Unit dimensions, WxHxD: 1.4" x 1.17" x 3.3" (3.5 x 2.97 x 8.4 cm)
So, it might be close.
Thanks
Do you think there is any benefit to mounting the GPS antenna horizontally, the way it came oriented on the dog collar?
