Abstract

A network, network device and method is disclosed. In one embodiment, a method includes transmitting communication signals from a first network node to a second network node, where the first and second network nodes comprise a network and each include a receiver portion and a transponder portion. The method further comprises receiving, by the first and second network nodes, position signals from a plurality of navigation beacons, and generating transmitter codes for the transponder portions using local code generators of the receiver portions.

Claims

1. A positioning device coupled to a network, comprising:

a receiver to receive position signals from a plurality of navigation beacons, said receiver to include a receiver code generator;

a transponder to receive and transmit communication signals, said transponder to use said receiver code generator as a transmitter code generator;

a processor coupled to the receiver and transponder; and

a memory coupled to the processor to store one or more instruction sequences, said instruction sequences to cause the positioning device to transmit said communication signals between said positioning device and another positioning device wherein the receiver code generator of the positioning device generates a unique transmitter code such that the transponder transmits a unique code for the positioning device within the network regardless of a position of the transponder of the positioning device and a position of the another positioning device.

2. The positioning device of claim 1, wherein a signal modulation process of said positioning device is reciprocal to a signal demodulation process for said positioning device.

3. The positioning device of claim 2, wherein said signal modulation process and signal demodulation process are based on modulo-2 addition.

4. The positioning device of claim 1, wherein said communication signals are generated by direct conversion using binary phase shift keying.

5. The positioning device of claim 1, wherein said receiver is a direct sequence spread spectrum positioning receiver.

6. The positioning device of claim 5, wherein said receiver uses correlators and pseudo random number (PRN) code tracking loops for synchronization, and wherein signals from said correlators and PRN code tracking loops are inputted to a complimentary code keying (CCK) modulator to generate said communication signals.

7. The positioning device of claim 6, wherein said signals from said correlators and PRN code tracking loops are combined and summed to provide a CCK signal.

8. The positioning device of claim 7, wherein said CCK signal is up-converted to change a frequency of the CCK signal to match a frequency of said communication signals.

9. The positioning device of claim 1, wherein said positioning device is addressable using one or more spatial parameters which include at least one of a position parameter and a velocity parameter.

10. The positioning device of claim 1, wherein said memory further includes a topology of the network, said topology to be updated in response to network topology changes.

11. The positioning device of claim 1, further comprising a master transmitter that sets the basic frequency and phase of said network and said positioning device.

12. The positioning device of claim 1, further comprising a plurality of navigation beacons which transmit position signals to said positioning device.

13. The positioning device of claim 12, wherein said communication signals are synchronized to said position signals.

14. The positioning device of claim 12, wherein said communication signals are used as ranging signals for other positioning devices coupled to the network, said other positioning devices to determine signal propagation time using signal time tagging.

15. The positioning device of claim 12, wherein said communication signals substitute for said position signals in determining position information.

16. The positioning device of claim 15, wherein said communication signals are used to provide frequency and signal phase assistance in the determination of position information.
