Project for vector calculus

Hello there,

So, for my project in Vector Calculus:

The suggestion is that we pick a certain "curve" within a country road. We are to log longitude, latitude and altitude while we drive this "curve" for approximately 15-20 seconds.

With the data from the latitude-longitude-altitude "logger", we are to perform the various vector calculus principles we have learned in class.

Instead of driving the road, I would like to attach whatever latitude-longitude-altitude logger to a boomerang, and get my curve through flight.

Does anyone know which sensor I should be looking for?

A bit about me:
I am currently an electrical engineering technician in product development for a motor-controls company. I mostly test hardware/software, which is designed by our in-house engineers. I am very comfortable with soldering, visual inspection of PCBs, schematics, and general electrical engineering knowledge.

Does anyone have a feasible idea for getting a gps unit onto a boomerang, and be ale to transmit the data to me in real-time?

Thanks in advance.

Good luck finding a sensor that can eliminate the spin....
