# Fused global position in WGS84. |
|
# This struct contains global position estimation. It is not the raw GPS |
|
# measurement (@see vehicle_gps_position). This topic is usually published by the position |
|
# estimator, which will take more sources of information into account than just GPS, |
|
# e.g. control inputs of the vehicle in a Kalman-filter implementation. |
