A GPS module that runs up to 18 Hz, links to your Android phone, and gets power via USB.
This module comes with a holo sticker, and a remote, magnetic antenna for GPS data. Because the antenna is remote, the module itself can be stored in an armrest or even zip-tied to a roll bar.

- Micro USB cable (who doesn't have one in a drawer somewhere?)
Android only
For use in transportation vehicles only
Quarter included for size comparison only (don't be that guy)
Instructions can be found here

Customer Reviews
It consistently pulls in higher frequency than 18hz.
The magnetic base on the antenna is great.
I ended up using a shorter usb cable that I had laying around, I didn't want a bunch of cable under the dash
GPS_BT - 18Hz External GPS
GPS_BT - 18Hz External GPS
Mounted the antenna on top on the dash, parked inside the garage under the insulated aluminum roll up door and surrounded by 70 foot pine trees. Not a problem, all 18hz available!
The best way to get faster is seat time. The next best way is to analyze your seat time and find where you're losing time. Using just your phone, every app on the market seems to only store data as fast as the selected GPS, which with your phone GPS selected means you are limited to 1Hz. I went with Harry's and an OBDLink MX+ and was frustrated because steering and throttle inputs, as well as track position, are just about impossible to analyze because a 1s resolution is a huge amount of time on track.
I purchased this and it works flawlessly as an external GPS with Harry's Lap Timer. Now, I have both the OBDLink MX+ and this GPS as sensors in Harry's and the difference is night and day.
I took a few screenshots from Harry's from my fastest lap at MSR Houston with the phone GPS and then my fastest lap at ECR with this GPS and I've put them here for comparison.
Hopefully it's obvious from the photos, but the increased precision allows you to actually see your inputs to a much greater degree.
