Hmmm, I think I may know what you want, do you mean.......
1:Send a radio signal to a base(s) to say "I am going to send and ultrasonic pulse"
2:Base(s) then listen, and time the period to get that pulse, and so knows the distance to the base?
I think the speed of sound is 340.29 M/s in air at sea level so you should be able to calulate this. BUT there is a small problem Radio modules can have a variable delay from TX to RX, I know because I code for them, alot, this can vary up to 10uS depending on modules etc.... so you will have to take this into account.
Anyway, this sounds an interesting idea, how can we help? (If I have go the right end of the stick!)
