>>12304738Here's a dissertation from UCLA, can skim through to find some good descriptions of pulsar nav methodology:

But the tl;dr is essentially: I start by knowing where I started, and what time it was. Then, lock on to the pulsar signals to determine their reference signals, then by comparing my received signal to that reference, I can use the phase and doppler shift of the received signal to determine my position and velocity.
