Pixhawk PX4 Support - Vehicle GPS block parameters

3 views (last 30 days)
In the example the sample time of this block is set to 1/250, but GPS outputs data between 1 to 10hz. Is this block already outputs a fusion/filtered with the inertial sensors?? If not, why the high sample time of this block? Thanks

Tony, This is the sample time of the block in the Simulink model. This is basically saying that the data will be sampled at 250 Hz - it has no bearing on how often new data is available from the hardware. You can easily set this to a different sample time in your model - but it won't change the output rate of the GPS module. The GPS block will just output the latest values, until they get updated by the GPS sensor publisher module.

The "GPS" block only outputs GPS data; Lat, Lon, Alt, etc... no inertial data.
