Detailed Description

Handles the creation and updating of GNSSPerception instances from sensor_msgs::msg::NavSatFix messages.

This class provides methods to register subscriptions to GNSS topics and update GNSSPerception objects.

Member Function Documentation

create()

std::shared_ptr< PerceptionBase > create ( const std::string & )

overridevirtual

Creates a new empty GNSSPerception instance.

Parameters

sensor_id

Name or identifier of the sensor. Currently unused, reserved for future extensions.

Returns

Shared pointer to a newly created GNSSPerception.

Implements PerceptionHandler.

create_subscription()

rclcpp::SubscriptionBase::SharedPtr create_subscription ( rclcpp_lifecycle::LifecycleNode & node, const std::string & topic, const std::string & type, std::shared_ptr< PerceptionBase > target, rclcpp::CallbackGroup::SharedPtr cb_group )

overridevirtual

Creates a subscription to an GNSS topic that updates a target GNSSPerception.

The subscription receives sensor_msgs::msg::NavSatFix messages on topic and writes the content into GNSSPerception::data, updating inherited metadata (stamp, frame_id).

Parameters

node	Lifecycle node used to create the subscription.
topic	Topic name to subscribe to.
type	ROS message type name. It must be "sensor_msgs/msg/NavSatFix".
target	Shared pointer to the GNSSPerception to be updated.
cb_group	Callback group for executor-level concurrency control.

Returns

Shared pointer to the created subscription.

Implements PerceptionHandler.

group()

std::string group ( ) const

overridevirtual

Returns the group managed by this handler.

Returns

The string literal "gnss".

Implements PerceptionHandler.
