Or, you can send a signal between the two stations by an RF link. If I recall correctly, you'd need to compensate for propagation variations, but, a two way scheme might work for that. I think I have a paper somewhere that talks about how they did that for VLA.
You need to either transmit at the same frequency alternating or transmit at different frequencies, but dual frequency such that you can compensate for any dispersion in order to aviod first grade dispersion errors.
Also, care must be taken in calibrating the stations own contributions to asymmetry. A de-tuned LC tank in the receiver path for one receiver for instance shifts the delay asymmetrically.
But done with some care you should be able to get fairly good results if you pick suitable frequencies, have line-of-sight and similar "good" conditions.
