float-solution calculation

Hi,

I am a student doing research in GPS survey with unmanned-vehicle system

I want to know is it possible to calculate float-solution in single-epoch with double-difference carrier phase measurement?

I have tried using code and phase measurement to calculate float solution
(dx,dy,dz and ambiguity vector)

but the results are not very well,

so I want to use phase measurement only

Can someone please give me some suggestion?

Thanks for your reading!

 

Hi, eggy
Did you solve the issues.?? If you solved the problem regarding please share with me. such as how did your form double difference and how did you apply least squre of kalman filtar for float solution?? please if you have matlab code provide me.
Thanks in advence
