[ros-users] EKF Error

[sam weiss]

We are currently trying to run the ros ekf package with two input sources,
odom motor data, and gps data. The gps data is remapped to the visual
odometry message. We are receiving this error when running the EKF:
[ERROR] 1274121205.429497000: filter time older than vo message buffer

What is the cause of this error?
