I recently bought a BU-353 G-STAR IV GPS receiver (common low cost GPS receiver in market). The update frequency according to the data sheet is 1 Hz. I set a baud rate of 4800 first and then 9600. But the map shows new position only after walking for 15 to 20 meters. Is this the norm? Is this because my GPS receiver's accuracy is 15 to 20 meters? Can I do any thing to obtain the current GPS location every second? i.e Can I update the resolution of the GPS dongle?
I am wondering why even the GPS in my smart phone seems to be at a higher resolution! The map shows continuous waypoints.
