configure the sampling frequency of gps receiver of "matlab mobile sensor" App

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

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.

So what would be the best way to incorporate the two measurements?

If you wanted to plot the two data points IMU and GPS.Speed (For example), would simply try to interpolate the time series on the GPS data points to fill in the gaps?

This moring, I did a sensor log of the Acceleration and GPS and I wanted to plot the Acceleration and GPS Speed over time. But because the two series aren't the same dimension, I have been contemplating how to navigate that.
