after a bit more research iv found i need to use the non linear least squares method in MATLAB, but still having trouble coding it. if the ranges from the satellites were perfect i could use the simultaneous equations 0 =...

Can someone please shed some light on the exact method for finding the two points at which the spheres created by the GPS signals from 3 different satellites intersect? I have been working on a uni project for 4 days now and still can't get this relatively simple part of my MATLAB code to work...

hmmm, think i figured it out from the derivation. ax,ay,az are the body accelerations and xdotdot, ydotdot and zdotdot are the Earth axis accelerations. still, if someone could confirm that would be appreciated.

Pieter you must be in my class, I have the same assignment. In class he gave us the equations: ax (x is subscript)= xdotdot - (2v/r0)*zdot - (v/r0)^2*x ay = ydotdot az = zdotdot + (2v/r0)*xdot - (v/r0)^2 but he was very vague about the symbol meanings. i don't know what ax refers to, as...
