pub struct NavSatFix {
    pub header: Header,
    pub status: NavSatStatus,
    pub latitude: f64,

    pub position_covariance: [f64; 9],

}

Navigation Satellite fix for any Global Navigation Satellite System

Specified using the WGS 84 reference ellipsoid

Fields

header: Header

header.stamp specifies the local time for this measurement (the corresponding satellite time may be reported using the TimeReference message).

status: NavSatStatus

latitude: f64

Latitude [degrees]. Positive is north of equator

longitude: f64

Longiture [degrees]. Positive is east of the prime meridian.

altitude: f64

altitude [m]. NaN if altitude is not available.

position_covariance: [f64; 9]

Position covariance [m^2] defined relative to a tangential plane through the reported position. The components are East, North, and Up (ENU), in row-major order.

Beware: this coordinate system exhibits singularities at the poles.

covariance_type: CovarianceType

If the covariance of the fix is known, fill it in completely. If the GPS receiver provides the variance of each measurement, put them along the diagonal. If only Dilution of Precision is available, estimate an approximate covariance from that.

Implementations

impl NavSatFix

pub fn create_topic_with_name( participant: &DdsParticipant, name: &str, maybe_qos: Option<DdsQos>, maybe_listener: Option<DdsListener>, ) -> Result<DdsTopic<Self>, DDSError>

Create a topic using of this Type specifying the topic name

Arguments

• participant - The participant handle onto which this topic should be created
• name - The name of the topic
• maybe_qos - A QoS structure for this topic. The Qos is optional
• maybe_listener - A listener to use on this topic. The listener is optional

pub fn create_topic( participant: &DdsParticipant, maybe_topic_prefix: Option<&str>, maybe_qos: Option<DdsQos>, maybe_listener: Option<DdsListener>, ) -> Result<DdsTopic<Self>, DDSError>

Create a topic of this Type using the default topic name. The default topic name is provided by the Self::topic_name function.

Arguments

• participant - The participant handle onto which this topic should be created
• maybe_topic_prefix - An additional prefix to be added to the topic name. This can be None
• maybe_qos - A QoS structure for this topic. The Qos is optional
• maybe_listener - A listener to use on this topic. The listener is optional

pub fn create_sample_buffer(len: usize) -> SampleBuffer<NavSatFix>

Create a sample buffer for storing an array of samples You can pass the sample buffer into a read to read multiple samples. Multiple samples are useful when you have one or more keys in your topic structure. Each value of the key will result in the storage of another sample.

Trait Implementations

impl<'de> Deserialize<'de> for NavSatFix

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for NavSatFix

impl TopicType for NavSatFix

fn key_cdr(&self) -> Vec<u8>

return the cdr encoding for the key. The encoded string includes the four byte encapsulation string.

fn is_fixed_size() -> bool

fn has_key() -> bool

fn force_md5_keyhash() -> bool

fn hash(&self, basehash: u32) -> u32

fn typename() -> CString

The type name for this topic

fn topic_name(maybe_prefix: Option<&str>) -> String

The default topic_name to use when creating a topic of this type. The default implementation uses ‘/’ instead of ‘::’ to form a unix like path. A prefix can optionally be added
