Class GpggaParser

java.lang.Object

avcl.translate.TelemetryFileTranslator

avcl.translate.GpggaParser

All Implemented Interfaces:

TelemetryTranslatorInterface

public class GpggaParser
extends TelemetryFileTranslator

Parses GPGGA lines. GPGGA is a standard NMEA format; format is $GPGGA,092204.999,4250.5589,S,14718.5084,E,1,04,24.4,19.7,M,,,,0000*1F where field 1 = UTC time, hhmmss.sss, latitude in form ddmm.mmmm, N/S indicator, longitude in format dddmm.mmmm, E/W, position fix where 0=invalid, 1 = valid SPS, 2 = valid DGPS, 3 - valid PPS, satellites used, hor dilution of precision, altitude, and altitude units. In the above string, lat = 42.505589S, lon = 147.185084 E, alt = 19.7, units = meters. Fields are comma delimited. Converts gpgga file to avcl document

GpggaParser

public GpggaParser()

Used by GUI through TelemetryTranslatorInterface i/f

Exception

Method Detail

toString

public String toString()

Description copied from interface: TelemetryTranslatorInterface

Returns a string description of the translator, suitable for user viewing in GUIs.

Specified by:

toString in interface TelemetryTranslatorInterface

Specified by:

toString in class TelemetryFileTranslator

Returns:

String description of the translator

getDefaultAvclDocument

public AVCL getDefaultAvclDocument()

Creates a mostly-filled-out AVCL document that lacks only the telemetry data.

Overrides:

getDefaultAvclDocument in class TelemetryFileTranslator

Returns:

a default AVCL telemetry mission specific to this type of vehicle

parse

public void parse()

After the constructor has been called, we've created a file writer that we can send events to. Theoretically we can also set up a listener pattern so that we can notify more than one recipient of our parse events, but there is no need for that here, at least for right now.

Specified by:

parse in interface TelemetryTranslatorInterface

Specified by:

parse in class TelemetryFileTranslator

main

public static void main(String[] arguments)

Test case entry point.

Parameters:

arguments - command line arguments if any

getTelemetrySampleRate

public double getTelemetrySampleRate()

Description copied from class: TelemetryFileTranslator

Accept data no more frequently than this

Specified by:

getTelemetrySampleRate in interface TelemetryTranslatorInterface

Overrides:

getTelemetrySampleRate in class TelemetryFileTranslator

Returns:

the minimum time (in seconds) between telemetry data points
