Detailed Description

Base class for a global position measurement provider.

Member Function Documentation

reset()

void px4_ros2::GlobalPositionMeasurementInterface::reset ( )

inline

Notify the FMU that the global position estimate has been reset.

Increments the reset counter for horizontal position (latitude and longitude) to signal the EKF of a discontinuity in external position data (e.g., loss of tracking or reinitialization). Future measurement updates will contain the incremented counter. This prevents the EKF from rejecting future measurement updates after an inconsistency in data.

update()

void px4_ros2::GlobalPositionMeasurementInterface::update

(

const GlobalPositionMeasurement &

global_position_measurement

)

const

Publishes a global position measurement to the FMU. Throws an exception if the following conditions are not met:

1. The sample timestamp is defined.
2. Values do not have a NAN.
3. If a measurement value is provided, its associated variance value is well defined.

   Parameters

   global_position_measurement

   The global position measurement to publish.

   Exceptions

   px4_ros2::NavigationInterfaceInvalidArgument

   if the conditions above are not met.
