NAME
stw_GetGPS - cmd line tool to fetch GPS data
SYNOPSIS
stw_GetGPS [-hvmja]
DESCRIPTION
This application asks the GPS data structure via dbus from the ygpsd.
Structure T_DBUS_GPS_Data
typedef struct
{
charn acn_status[32];
// NONE = fix not available,
// NMEA = receiving valid nmea string from gps receiver
charn acn_latitude[32];
// Degrees notation: DD.dddddd
charn acn_longitude[32]; // Degrees notation: DD.dddddd
charn acn_altitude[32]; // Above/below mean-sea-level in meters
charn acn_time[32]; // hhmmss
charn acn_satellites[32]; // number of satellites used in solution
charn acn_quality[32]; // 0 = no reception - 1 good ,
charn acn_warn[32];
// V = GPS position is not valid
// A = GPS position is valid
charn acn_speed[32]; // Speed over ground km/h XXX.YYYYYY
charn acn_course[32]; // Degrees (0..360) XXX.YYYYYY
charn acn_date[32]; // ddmmyy
charn acn_UTC[64]; // MMDDhhmmYYYY
} T_DBUS_GPS_Data;
Therefore, the ygpsd needs to be up and running.
The application parses the information from the NMEA0183 strings GGA and RMC.
