Field Number:

1. Total number of messages
2. Sentence Number
3. Satellite PRN number (01 to 32)
4. GPS Week Number (range 0 to 2^13 - 1), where:
   • 0 is the week of the GPS Week Number epoch on January 6th 1980;
   • 8191 is the week that precedes the next rollover on January 6th 2137; Note: the legacy representation started at the same epoch, but the number is 10-bit wide only, with a rollover every 19.7 years.
5. Eccentricity
6. Almanac Reference Time
7. Inclination Angle
8. Rate of Right Ascension
9. Root of semi-major axis
10. Argument of perigee
11. Longitude of ascension node
12. Mean anomaly
13. F0 Clock Parameter
14. F1 Clock Parameter
15. Checksum

Fields 5 through 15 are dumped as raw hex.

Fields

total_number_of_messages: Option<u16>

sentence_number: Option<u16>

satellite_prn_number: Option<u8>

gps_week_number: Option<u16>

This is the modern 13-bit representation of the GPS week number. Use AlmData::get_10bit_gps_week_number() to get the legacy 10-bit representation.

Implementations

impl AlmData

pub fn get_10bit_gps_week_number(&self) -> Option<u16>

Returns the 10-bit representation of the GPS week number (range 0 to 1023)

Trait Implementations

impl Clone for AlmData

fn clone(&self) -> AlmData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AlmData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AlmData

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<AlmData> for AlmData

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for AlmData

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

Serialize this value into the given Serde serializer.

impl Copy for AlmData

impl Eq for AlmData

impl StructuralEq for AlmData

impl StructuralPartialEq for AlmData
