tengo un archivo dat donde contiene unas coordenadas en gps con la veolcidad altura etc. con el editor hexadecimal he podido encontrar la linea exacta de cada coordenada y identificar la latitud y longitud pero no se descifrarlo, aqui dejo un ejemplo:
lineas del dat en hexadecimal
aqui las coordenadas reales:
lo que he podido deducir es lo siguiente:
-Las dos primeras lineas indica la coordenada incial ni idea de como sacarla ni si hay mas informacion.
- si una coordenada tiene la siguiente forma: 83 60 FF FF 06 00 02 00 00 55 00
las FF FF son la latitud y 06 00 la longitud.
-La parte que hay despues del 83 diria que tiene algo k ver con el tiempo
-las lineas que empiezan por 93 indican que se ha pasado del reposo a una velocidad x y viceversa.

lo que he podido deducir es lo siguiente:
-Las dos primeras lineas indica la coordenada incial ni idea de como sacarla ni si hay mas informacion.
- si una coordenada tiene la siguiente forma: 83 60 FF FF 06 00 02 00 00 55 00
las FF FF son la latitud y 06 00 la longitud.
-La parte que hay despues del 83 diria que tiene algo k ver con el tiempo
-las lineas que empiezan por 93 indican que se ha pasado del reposo a una velocidad x y viceversa.
