Hi!
RetardoSat:
1.Come three samples (method work)
- X: X position of receiver.
- Y: Y position of receiver.
- Z: Z position of receiver.
- ClK: seconds.
2. With Kepler paremeters calculates the satellite position, the
distance between the satellite and the receiver and the signal delay.
3. Send to the output (t) the calculated delay.
float *out = (float*)output_items[0];
const float *inx = (const float *) input_items[0];
const float *iny = (const float *) input_items[1];
const float *inz = (const float *) input_items[2];
const float *inTOW = (const float *) input_items[3];
for(int i=0;inoutput_items;++i){
...
...
}
Reloj:
*Precision = tiempo inicial
**Tasa = sample rate
