What is a 10Hz Sensor Data Export?
The Sensor Export function provides a CSV export of GPS and inertial data sampled at 10Hz.
How to Export 10Hz Sensor Data
-
Open an Activity in the OpenField Console.
-
From the Active Players box, right click on the athlete you want to export Sensor data for. If multiple exports are wanted, select multiple athletes before right clicking.
-
Select Export Sensor CSV.
- Exports are saved to the My Documents folder on your computer.
Sensor Export Parameter Definitions
|
Metric |
Explanation |
Units |
|
Timestamp |
A time stamp relative to the start of the file, with a millisecond resolution. |
|
|
Velocity |
Current – Filtered velocity. |
m/s |
|
Acceleration |
Acceleration derived from Velocity. |
m/s2 |
|
Odometer |
Accumulated distance. |
m |
|
Latitude/Longitude |
The magnetic facing of the unit, derived from the IMU corrected magnetometers. |
degrees |
|
HeartRate |
Heart rate derived from the pickup pulses received from paired devices. |
bpm |
|
PlayerLoad |
3D player load derived directly from the calibrated accelerometer values. This is a filtered differential of the acceleration vector. |
AU |
| Positional Quality |
A parameter specific to Catapult that is calculated by taking the Signal to Noise ratio (SNR) from each satellite, sorting these according to their numerical value and providing them with a weighting factor. Stronger satellites are given a higher weighting in the quality total. |
% |
|
HDOP |
The dilution of precision which measures how much the geometrical arrangement of the satellites being measured will affect the precision of the result. |
|
|
#Sats |
The number of fixed satellites per data point. |
