Feature description
In NavSatStatus, there is a field for position covariance. Some GPS receivers also support velocity with a velocity covariance.
I'd like to request some fields added to report both the velocity and accuracy estimates of that velocity
Implementation considerations
There is some thought in other threads about re-adding the GPSFix message support. I'd like to get the ball rolling on this for ROS2 Iron, if possible, since there are two other tickets regarding the NavSatFix message. Seems like a good opportunity to bundle all the changes in one version bump.

Research direction
Start by locating the NavSatFix and NavSatStatus message definitions and reviewing the related tickets about re-adding GPSFix support. Clarify the proposed velocity and covariance fields, their compatibility with ROS2 Iron, and the required version bump; the issue does not define enough detail to establish completion criteria.
