I have noticed that the Matlab mobile sensor app allows the user the set the sampling rate.

However, it only applies to the sampling frequency of the IMU measurements, but not to the GPS receiver.

As shown in the below screenshot, there are 60,901 measurements of the orientation angle (from IMU), but only 22 position data.

Is there a way to set the sampling of the GPS receiver to the same rate as that of the IMU? so in this case, I will have 60901 measurements of the GPS data

Greetings Qiqin

Due to the way position data is collected, the GPS sensor may not read out at the sampling rate set by the user. The mobile device operating system (Android or iOS) generates new data points based on device movement and currently there is no way for users to control the rate of readout on MATLAB Mobile.

I hope this helps.

Best regards,

Suraj.
