how to open fusion gps function?

[liuchongxiao]

hi, many thaks for your work, I am using myself dateset, and my imu topic is "imu", gps topic is "fix", I change the lio_sam_default.yaml, and the gps topic and imu topic to the folowing:
pointCloudTopic: "velodyne_points" # Point cloud data
imuTopic: "imu" # IMU data
odomTopic: "odometry/imu" # IMU pre-preintegration odometry, same frequency as IMU
gpsTopic: "fix" # GPS odometry topic from navsat, see module_navsat.launch file
and I also change module_navsat.launch file as folowing :

my gps sensor type is: sensor_msgs/NavSatFix

however when I run the code, I can not see the Odom GPS in the rviz window, what else do I need change?
