Any thoughts on how complex a receiver would need to be to produce a 1 pps signal that was locked to the carrier frequency it was receiving ? Lot's of comercial transmitting equipment is designed to use an external frequency standard and if a transmitter at a high altitude site was locked to a cesium source it could serve a typical metroplitan area. Locking an existing transmiiter to a cesium standard would not require any special signals or wave forms to be transmitted. To be usefull the receiver would need to produce a standard 1 pps output.
