Hi Said,

What is affordable for you?

For some $330 you can get a L1 GPS receiver outputting carrier phase
measurements at 5Hz. This receiver also have a 10MHz tcxo driving the
whole receiver. Pseudorange measurement rms of a few dm. Carrierphase
rms below 1cm.

Btw... the Oncore VP did carrierphase measurements.
