Function Documentation

static void mavlink_msg_altitude_decode	(	const mavlink_message_t *	msg,
		mavlink_altitude_t *	altitude
	)

inlinestatic

Decode a altitude message into a struct.

Parameters

msg	The message to decode
altitude	C-struct to decode the message contents into

Definition at line 340 of file mavlink_msg_altitude.h.

static uint16_t mavlink_msg_altitude_encode	(	uint8_t	system_id,
		uint8_t	component_id,
		mavlink_message_t *	msg,
		const mavlink_altitude_t *	altitude
	)

inlinestatic

Encode a altitude struct.

Parameters

system_id	ID of this system
component_id	ID of this component (e.g. 200 for IMU)
msg	The MAVLink message to compress the data into
altitude	C-struct to read the message contents from

Definition at line 147 of file mavlink_msg_altitude.h.

static uint16_t mavlink_msg_altitude_encode_chan	(	uint8_t	system_id,
		uint8_t	component_id,
		uint8_t	chan,
		mavlink_message_t *	msg,
		const mavlink_altitude_t *	altitude
	)

inlinestatic

Encode a altitude struct on a channel.

Parameters

system_id	ID of this system
component_id	ID of this component (e.g. 200 for IMU)
chan	The MAVLink channel this message will be sent over
msg	The MAVLink message to compress the data into
altitude	C-struct to read the message contents from

Definition at line 161 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_altitude_amsl ( const mavlink_message_t * msg )

inlinestatic

Get field altitude_amsl from altitude message.

Returns: This altitude measure is strictly above mean sea level and might be non-monotonic (it might reset on events like GPS lock or when a new QNH value is set). It should be the altitude to which global altitude waypoints are compared to. Note that it is not the GPS altitude, however, most GPS modules already output AMSL by default and not the WGS84 altitude.

Definition at line 289 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_altitude_local ( const mavlink_message_t * msg )

inlinestatic

Get field altitude_local from altitude message.

Returns: This is the local altitude in the local coordinate frame. It is not the altitude above home, but in reference to the coordinate origin (0, 0, 0). It is up-positive.

Definition at line 299 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_altitude_monotonic ( const mavlink_message_t * msg )

inlinestatic

Get field altitude_monotonic from altitude message.

Returns: This altitude measure is initialized on system boot and monotonic (it is never reset, but represents the local altitude change). The only guarantee on this field is that it will never be reset and is consistent within a flight. The recommended value for this field is the uncorrected barometric altitude at boot time. This altitude will also drift and vary between flights.

Definition at line 279 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_altitude_relative ( const mavlink_message_t * msg )

inlinestatic

Get field altitude_relative from altitude message.

Returns: This is the altitude above the home position. It resets on each change of the current home position.

Definition at line 309 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_altitude_terrain ( const mavlink_message_t * msg )

inlinestatic

Get field altitude_terrain from altitude message.

Returns: This is the altitude above terrain. It might be fed by a terrain database or an altimeter. Values smaller than -1000 should be interpreted as unknown.

Definition at line 319 of file mavlink_msg_altitude.h.

static float mavlink_msg_altitude_get_bottom_clearance ( const mavlink_message_t * msg )

inlinestatic

Get field bottom_clearance from altitude message.

Returns: This is not the altitude, but the clear space below the system according to the fused clearance estimate. It generally should max out at the maximum range of e.g. the laser altimeter. It is generally a moving target. A negative value indicates no measurement available.

Definition at line 329 of file mavlink_msg_altitude.h.

static uint64_t mavlink_msg_altitude_get_time_usec ( const mavlink_message_t * msg )

inlinestatic

Send a altitude message.

Parameters

chan	MAVLink channel to send the message
time_usec	Timestamp (milliseconds since system boot)
altitude_monotonic	This altitude measure is initialized on system boot and monotonic (it is never reset, but represents the local altitude change). The only guarantee on this field is that it will never be reset and is consistent within a flight. The recommended value for this field is the uncorrected barometric altitude at boot time. This altitude will also drift and vary between flights.

altitude_relative	This is the altitude above the home position. It resets on each change of the current home position.
altitude_terrain	This is the altitude above terrain. It might be fed by a terrain database or an altimeter. Values smaller than -1000 should be interpreted as unknown.
bottom_clearance	This is not the altitude, but the clear space below the system according to the fused clearance estimate. It generally should max out at the maximum range of e.g. the laser altimeter. It is generally a moving target. A negative value indicates no measurement available. Get field time_usec from altitude message
