It certainly uses some formulas to calculate power.
I want to know those formulas and calculations.
The GPS calculates changes in position and time. So basically the GPS can measure change in distance and change in time and using that information you can find the following:
Velocity = 'Change in Distance' / 'Change in Time'
Acceleration = 'Change in Velocity' / 'Change in Time'
Force = Mass * Acceleration [Mass is the vehicle weight you have to enter]
Power = Force * Velocity
In summary the GPS calculates velocity and force (where the force depends on the vehicle weight) and from those quantities power can be estimated.
