The goal is to perform sensor fusion using an extended kalman filter and my csv file has information of IMU and GPS data. When I now use the rqt_marble_plugin it doesn't display the /vehicle/gps submessage. The video stream from Bebop’s front camera is published on image_raw topic as sensor_msgs/Image messages. See full list on github. To export the image topic to jpegs, the bag needs to be played back and the frames extracted. Drive around faster than 5 m/s for a short period of time after powering on the OxTS unit to initialize the sensor. Can I somehow fix this? I would like to be able to publish this VehicleData msg and subscribe either to the whole topic or to subtopics. The topics starting with /piksi/ are published by the ROS driver and represent data that is available from the currently connected device.

Topics used to obtain information about the status of the FCU and aircraft power buses. Although NavSatFix provides many information, we use only (lat, lon, alt) and ignore all other data. Data is not published until the OxTS unit reports itself as being completely initialized. A well chosen acquisition with lots of loop closure constraints (for instance if your robot goes on a straight line and then back) can improve the quality of those corrections and become a reliable source of pose correction.
