Speed
We measure the speed of your run directly from the GPS. At 10 measurements per second, you get a much more refined measurement!
Acceleration
Results are output in multiples of gravity, or "g's", in three perpendicular directions. This is why it's important to specify how Ripxx is worn or oriented on what you're trying to measure. From these three measurements, your total acceleration vector is known.
Time
Each Ripxx unit is automatically synchronized to the same time from GPS satellites. Not only does this allow us to keep track of the local time and when you did your thing, it means that multiple Ripxx units are exactly synchronized. That means you can compare data between devices easily. You can even use multiple Ripxx devices to synchronously measure multiple points on the same body or vehicle!
Air Time
We compute your air time by understanding the accelerations you experience. A simple jump produces zero "g" (or close to it). The solution is more complicated when you're spinning and flipping though. Ripxx gets it and does the computation right!
Distance
Distance traveled is computed from the GPS measurements.
Jump
Because we can accurately determine your air time (even while rotating!), we can use this information to compute your jump statistics. So, we can compute stuff like jump height and distance.
Roll Rate
The three, perpendicular gyroscopes in Ripxx directly measure your roll rate. That means degrees per second. Because we measure three of them, we can also compute the overall rotation vector. Integrating this lets us calculate other cool stuff like your flips and spins.
Spins and FlipsOnce we measure your roll rates, determining spins and flips is done by integration. A fancy process that simply means we keep track of how long you're rotating and add it up. Degrees per second times seconds equals degrees - simple.
Vertical Drop
Ripxx gets this the same way we get overall distance traveledÉwe use the GPS. Accuracy is 3 or 4 meters.
Altitude
This is direct output from the GPS. Again, with 10 measurements per second on the GPS, we do it better than anyone. Accuracy is again 3 or 4 meters.
Slope
Tells you how steep the terrain was.
