   basically do whatever you want with this code.
 
   This example shows how to configure the U-Blox GNSS to output multiple messages at different rates:
-  PVT is output once per measurement;
-  POS_ECEF is output every second measurement;
-  VEL_NED is output every third measurement.
+  PVT is output every second;
+  POSECEF is output every five seconds;
+  VELNED is output every ten seconds.
 
   Feel like supporting open source hardware?
