Abstract
An integrated split-spectrum pseudolite/satellite base station (SS-PL)/SBS transmitter comprising a satellite base station and a split-spectrum pseudolite (SS-PL) transmitter co-located with the satellite base station. The satellite base station provides a timing synchronization signal. The satellite base station also provides a self-surveying capability for the split-spectrum pseudolite (SS-PL). The split-spectrum pseudolite (SS-PL) generates a split-spectrum sideband signal that minimizes interference with the reception of at least one satellite signal by the satellite base station.

An integrated split-spectrum pseudolite/satellite base station (SS-PL)/SBS transmitter comprising:
- a satellite base station;
- a split-spectrum pseudolite (SS-PL) transmitter co-located with said satellite base station;
- and
- a connection line between said satellite base station and said (SS-PL) transmitter;
- wherein said satellite base station provides a timing synchronization signal;
- and wherein said satellite base station provides a self-surveying capability for said split-spectrum pseudolite (SS-PL);
- and wherein said connection line is used to transmit synchronously a set of satellite data from said satellite base station to said (SS-PL) transmitter;
- and wherein said integrated split-spectrum pseudolite/satellite base station (SS-PL)/SBS transmitter transmits a message including said synchronized satellite data.
A method of generating a split-spectrum sideband signal by an integrated split-spectrum pseudolite/satellite base station (SS-PL)/GPSD transmitter having a delay D identification number;
- said method comprising the steps of:
- providing a timing synchronization signal by said satellite base station;
- providing a self-surveying capability for said split-spectrum pseudolite (SS-PL) by said satellite base station;
- using a connection line to transmit synchronously a set of satellite data from said satellite base station to said (SS-PL) transmitter;
- generating a split-spectrum sideband signal by said integrated split-spectrum pseudolite/satellite base station (SS-PL)/GPSD transmitter;
- and
- using said integrated split-spectrum pseudolite/satellite base station (SS-PL)/SBS transmitter to transmit a message including said synchronized satellite data;
- wherein said split-spectrum sideband signal includes a set of position coordinates for said integrated split-spectrum pseudolite/satellite base station (SS-PL)/GPSD transmitter having said delay D identification number.
An integrated split-spectrum pseudolite/satellite base station (SS-PL)/SBS transmitter comprising:
- a means for providing a timing satellite synchronization signal;
- a means for providing a surveying capability for said split-spectrum pseudolite (SS-PL);
- and
- a means for generating a split-spectrum sideband signal;
- wherein said means for providing said timing satellite synchronization signal and said means for providing said surveying capability for said split-spectrum pseudolite (SS-PL) are linked to said means for generating said split-spectrum sideband signal.
