Ublox GPS ground speed/course can not update consistently #10

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Activate the itow for class NAV-VELNED
2. Compare the two itows for class NAV-POSLLH and for class NAV-VELNED, they 
are different
3. When I print the ground speed/course, sometimes they update while sometimes 
they just stop updates, very inconsistent

What is the expected output? What do you see instead?
The ground speed/course should updates at the same time as the GPS longitude, 
latitude, altitude,etc. What I observe is they can not do that

What version of the product are you using? On what operating system?
1.7.1 and 1.8.1 versions, windows vista, Arduino 0021.

Please provide any additional information below.
when I disable the SOL message on Ublox, the ground course and speed update 
together with the latitude, longitude, etc.
