One mod DJI Phantom 2 users are doing to their drones to improve GPS is removing the original 2mm GPS antenna and replacing it with a Taoglas 4mm GPS antenna. It can be found at Digikey.com here, Taoglas GP.1575.25.4.A.02.
If you live in the US, for less than $10 shipped and an hour or so of your time you can improve the GPS reception of your Phantom 2!
This modification does take some soldering skills and patience. You do not want to accidentally break the GPS module as its around $175… With that said, it isn’t too difficult to do as long as you take your time.
Disclaimer: Perform this modification at your own risk. This article is only a guide for entertainment purposes. Drone Garage is not responsible for any damage that YOU do to your drone. Also, be aware that this modification may void your warranty.
Let’s get started!
- Soldering iron & solder
- wire cutter (to cut plastic ridges from top shell)
- dremel and grinding tip to smooth and clean ridges from top cover
- box cutter or flat blade
If you have never opened up your Phantom before, check out this video by Simon Newton on how to do so. How to open the DJI Phantom 2, Vision, Vision+ (& how to remove the camera on Vision)
Once you have the cover removed here, set everything else aside since this is what you’ll be focusing on:
You’ll see four small screws holding the GPS module in. Carefully remove them to detach the GPS module.
And final results can be seen in the Youtube video here:
The video shows an improvement in GPS satellite acquisition indoors, but unfortunately I didn’t get full GPS satellite lock as I had with a different Phantom and the same mod.
UPDATE! GPS LOCK AQUIRED INDOORS IN LESS THAN 30 SECONDS!

This Phantom 2 is now for sale as well. It was a “parts” Phantom revived and upgraded! Sold to LF on Facebook via one of the Phantom Group pages!
For reference here are a few threads on Phantompilots.com of user success stories, tips, and conversation about the upgrade.
