This repository contains the ROS packages for the Vectornav INS & GPS devices.
NOTE: Currently only Vectornav VN100 with version
2.1.0and3.0.0has been tested. Please open an issue if you need support for other versions.
The following parameters for vnpub node:
Required:
~serial_port (string, required): The device name of the Vectornav device. For example, /dev/ttyUSB_IMU.~serial_baud (int, required): The baudrate of the Vectornav device. For example, 115200.~frame_id (string, required): The frame id of the Vectornav device. For example, robot_imu_link.Optional:
~acc_bias_enable (bool, default: false): Enable service to calibrate accelerometer bias.
~set_acc_bias_seconds (double, default: 2.5): Time in seconds to take samples for accelerometer bias calibration.
~async_output_rate (int, default: 200): The rate of the async output. For example, 200.
~fixed_imu_rate (int, default: 800): The fixed rate of the IMU data. For example, 800.
~adjust_ros_timestamp (bool, default: true): Use sensor timestamp instead of ROS timestamp to mitigate USB communication issues.
~map_frame_id (string, default: map): The map frame id of the Vectornav device. For example, map.
~linear_accel_covariance (double[9], default: [0.01, 0, 0, 0, 0.01, 0, 0, 0, 0.01]): The covariance of the linear acceleration.
~angular_vel_covariance (double[9], default: [0.01, 0, 0, 0, 0.01, 0, 0, 0, 0.01]): The covariance of the angular velocity.
~orientation_covariance (double[9], default: [0.01, 0, 0, 0, 0.01, 0, 0, 0, 0.01]): The covariance of the orientation.
~rotation_reference_frame (double[9], default: [1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0, 0, 1.0]): The rotation reference frame of the Vectornav device. For example, [1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0, 0, 1.0] for NED frame.
The following topics are published by the vnpub node:
~data (sensor_msgs/Imu): The IMU data with standard ROS messages.~mag (sensor_msgs/MagneticField): The magnetic field data with standard ROS messages.~gps (sensor_msgs/NavSatFix): The GPS data with standard ROS messages.~odom (nav_msgs/Odometry): The odometry data with standard ROS messages.~temperature (sensor_msgs/Temperature): The temperature data with standard ROS messages.~atm_pressure (sensor_msgs/FluidPressure): The atmospheric pressure data with standard ROS messages.~ins_status (vectornav_msgs/InsStatus): The INS status data with custom ROS messages.The following services are provided by the vnpub node:
~set_acc_bias (vectornav_msgs/SetAccBias): Set the accelerometer bias to [0.0, 0.0, 9.81] with mean of samples taken during set_acc_bias_seconds seconds.~reset_acc_bias (std_srvs/Empty): Reset the accelerometer bias to zero.NOTE: The services are only available if
acc_bias_enableis set totrue.
