Hello, EEVblog peoples ! always thanks you for your kind help.
I have a question about define user position from GPS Satellite positions.
Now, I have following data.
GDOP
1st Satellite X, Y, Z coordinates and Pseudo Range of 1st Satellite.
2nd Satellite X, Y, Z coordinates and Pseudo Range of 2nd Satellite.
3rd Satellite X, Y, Z coordinates and Pseudo Range of 3rd Satellite.
4th Satellite X, Y, Z coordinates and Pseudo Range of 4th Satellite.
I have tried already for one week. but, Still I couldn't define and calculate the user position.
I have used following information to calculate.
pr = sqrt( (x-X)^2 + (y-Y)^2 + (z-Z)^2 )
(

might be, only with these information, define user position is impossible ?
Please, let me know !
