A network of non-cooperative integrated pseudolite (PL)/satellite base station (SBS) transmitters covering an open area. The network comprises a first plurality (K) of integrated pseudolite/satellite base station (PL)1/(SBS) transmitters, located in an open area A, and a second plurality (M) of non-cooperative integrated PL2/SBS transmitters, located in an open area B. K and M are integers. Each PL transmitter is co-located with one SBS. Each SBS provides a satellite timing synchronization signal. Each integrated active (transmitting) PL/SBS transmitter transmits its position location as a part of its message. The first plurality (K) of integrated PL1/SBS transmitters includes a substantially sufficient number of active integrated PL1/SBS transmitters in order to fill out satellite shades of coverage and to substantially cover the area A. Each integrated PL2/SBS transmitter continuously detects a plurality of ranging signals transmitted by each active integrated PL1/SBS transmitter. Each integrated PL2/SBS transmitter includes a processor including an algorithm comprising at least the following logic: each integrated PL2/SBS transmitter does not transmit if the plurality of active integrated PL1/SBS transmitters substantially covers the area B; and at least a plurality sub-of integrated PL2/SBS transmitters starts transmitting, if a plurality of integrated PL1/SBS transmitters does not substantially cover the open area B.
