MAVLink ALTITUDE message.

The minimum supported MAVLink version is MAVLink 1.

Description

The current system altitude.

Encoding/Decoding

Message encoding/decoding are provided by implementing core::convert::TryFrom<Payload> for Altitude (encoding) and [IntoPayload] (decoding) traits. These traits are implemented by Message proc macro.

Fields

time_usec: u64

MAVLink field time_usec.

Timestamp (UNIX Epoch time or time since system boot). The receiving end can infer timestamp format (since 1.1.1970 or since system boot) by checking for the magnitude of the number.

altitude_monotonic: f32

MAVLink field 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_amsl: f32

MAVLink field altitude_amsl.

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 MSL by default and not the WGS84 altitude.

altitude_local: f32

MAVLink field altitude_local.

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.

altitude_relative: f32

MAVLink field altitude_relative.

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

altitude_terrain: f32

MAVLink field 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: f32

MAVLink field 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.

Implementations

Trait Implementations

impl Clone for Altitude

fn clone(&self) -> Altitude

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Altitude

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Altitude

fn default() -> Altitude

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Altitude

fn deserialize<__D>( __deserializer: __D, ) -> Result<Altitude, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Altitude> for Common

fn from(value: Altitude) -> Common

Converts to this type from the input type.

impl IntoPayload for Altitude

fn encode(&self, version: MavLinkVersion) -> Result<Payload, SpecError>

Encodes message into MAVLink payload.

impl MessageSpec for Altitude

fn id(&self) -> u32

MAVLink message ID.

fn min_supported_mavlink_version(&self) -> MavLinkVersion

Minimum supported MAVLink protocol version.

fn crc_extra(&self) -> u8

Message EXTRA_CRC calculated from message XML definition.

impl MessageSpecStatic for Altitude

fn spec() -> MessageInfo

Returns specification for this message.

fn message_id() -> u32

Message ID.

fn crc_extra() -> u8

Message CRC_EXTRA.

fn min_supported_mavlink_version() -> MavLinkVersion

Minimum supported MAVLink version for this message.

impl NamedType for Altitude

fn sid() -> SpectaID

fn named_data_type( type_map: &mut TypeCollection, generics: &[DataType], ) -> NamedDataType

this is equivalent to Type::inline but returns a NamedDataType instead.

fn definition_named_data_type(type_map: &mut TypeCollection) -> NamedDataType

this is equivalent to [Type::definition] but returns a NamedDataType instead.

impl PartialEq for Altitude

fn eq(&self, other: &Altitude) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Altitude

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&Payload> for Altitude

type Error = SpecError

The type returned in the event of a conversion error.

fn try_from( value: &Payload, ) -> Result<Altitude, <Altitude as TryFrom<&Payload>>::Error>

Performs the conversion.

impl Type for Altitude

fn inline(type_map: &mut TypeCollection, generics: Generics<'_>) -> DataType

Returns the definition of a type using the provided generics.

fn reference(type_map: &mut TypeCollection, generics: &[DataType]) -> Reference

Generates a datatype corresponding to a reference to this type, as determined by its category. Getting a reference to a type implies that it should belong in the type map (since it has to be referenced from somewhere), so the output of definition will be put into the type map.

impl Flatten for Altitude

impl Message for Altitude

impl StructuralPartialEq for Altitude
