Why does my altitude drift when I ride in a velodrome?
Altitude deviation is a phenomenon that occurs in the velodrome. It can be caused by environmental factors such as barometric pressure, temperature or air density that may vary. While in a velodrome, you usually have a constant altitude*. The drift phenomenon can be set in post-processing treatment in Golden Cheetah Notio.
Top Menu -> Tools -> Altitude -> Constant (which equal to 0)
After selecting the constant altitude, it will automatically recompute the data and fix arbitrarily constant altitude to eliminate potential errors.
*Note: So that your elevation does not change when you ride on a velodrome, you must keep the same line and not go up or down in the corners.

The Golden Cheetah functionality to “Find intervals…” has been improved by adding a method to find laps in a velodrome (still in beta). It can be used for outdoor and indoor tracks. It is based on the Notio sensors. First, you will need to compute ...Is there a protocol to calibrate my Notio on outdoor velodrome?
Calibration on an outdoor velodrome is a big challenge. Especially because of environmental conditions. Yet, we have not determined a robust protocol for outdoor velodrome users. If you are a Notio user and you train on an outdoor velodrome, you will ...What does the Air density graph show?
This graph displays the Air density in kg per meter cubed (kg/m³). The changes during a ride are usually caused by a change in temperature and will also depend on the altitude. Generally, it will be closer to 1.15 kg/m³ in the summer and closer to ...I want to download Golden Cheetah Notio software.
