@Manu-Yareshimi The baud rate just sets the communication speed between the Omega and the GPS Expansion. This is unrelated to the number of GPS readings per second. I've never tried getting readings any faster than the default, but it looks like you will need to configure the GPS Expansion using AT commands to change the number of readings per second. I believe this is mentioned in the article you posted. It's also possible gpsd may not be able to keep up with faster readings. But let us know how it goes!
