Struct sbp::messages::navigation::msg_gps_time::MsgGpsTime

pub struct MsgGpsTime {
    pub sender_id: Option<u16>,

GPS Time

This message reports the GPS time, representing the time since the GPS epoch began on midnight January 6, 1980 UTC. GPS time counts the weeks and seconds of the week. The weeks begin at the Saturday/Sunday transition. GPS week 0 began at the beginning of the GPS time scale.

Within each week number, the GPS time of the week is between between 0 and 604800 seconds (=606024*7). Note that GPS time does not accumulate leap seconds, and as of now, has a small offset from UTC. In a message stream, this message precedes a set of other navigation messages referenced to the same time (but lacking the ns field) and indicates a more precise time of these messages.

Fields

sender_id: Option<u16>

The message sender_id

wn: u16

GPS week number

tow: u32

GPS time of week rounded to the nearest millisecond

ns_residual: i32

Nanosecond residual of millisecond-rounded TOW (ranges from -500000 to 500000)

flags: u8

Status flags (reserved)

Implementations

impl MsgGpsTime

pub fn time_source(&self) -> Result<TimeSource, u8>

Gets the TimeSource stored in the flags bitfield.

Returns Ok if the bitrange contains a known TimeSource variant. Otherwise the value of the bitrange is returned as an Err(u8). This may be because of a malformed message, or because new variants of TimeSource were added.

pub fn set_time_source(&mut self, time_source: TimeSource)

Set the bitrange corresponding to the TimeSource of the flags bitfield.
