This shouldn't be much of a problem. Using a chiping rate of a couple of kHz should be enough for this application. The signal strength can be rather large, directive antennas can be used and the expected noise level is rather low. So there no need to use a high chipping rate to compensate for noise effects. Of course, using a higher chipping rate makes it also easier to get an higher accuracy, but I would start with something easy to do first, like a 100mW transmitter in the 70cm band with 10kHz chipping rate (or go to a sub-band, where 200kHz signals are allowed). With that kind of setup it should be possible to use something like RTL-SDR for the first experiments and then gradually upgrade to better hardware to improve accuracy.
