I am working on a satellite tracking application where I can read NMEA data from file.
Here are the NMEA sentences I have:
$GPRMC,104426.591,A,5920.7019,N,01803.2893,E,0.117980,320.93,141204,,*0F $GPGGA,104427.591,5920.7009,N,01803.2938,E,1,05,3.3,78.2,M,23.2,M,0.0,0000*4A $GPGSA,A,3,05,24,17,30,02,,,,,,,,5.6,3.3,4.5*34 $GPGSV,3,1,12,30,72,254,30,05,70,125,39,24,37,083,43,02,36,113,45*7B $GPGSV,3,2,12,04,32,059,34,01,27,307,00,14,26,256,00,06,24,219,00*7F $GPGSV,3,3,12,17,22,135,40,25,20,311,31,09,19,159,25,20,08,346,34*7C
And where I need help is I have to get the "satellite position" from the sentence in lon/lat.
I know the GSV data contains azimuth and elevation, but I don't now how to convert it to lon/lat coordinates.
Can somebody help me?
