Abstract
A method and an apparatus for operating a satellite positioning system (SPS) receiver in a client/server architecture. In one example of a method a first plurality of pseudoranges is determined at a first time and a second plurality of pseudoranges is determined at a second time which is after the first time. The first and the second pluralities of pseudoranges are stored. After the second time the first and the second pluralities of pseudoranges are transmitted to a location server normally in one transmission. The location server then determines a first position from the first plurality of pseudoranges and a second position from the second plurality of pseudoranges. In one particular example the first and second pseudoranges are transmitted in response to a predetermined type of event and the location server stores a collection of differential GPS data which has been collected over time.

Claim
1. A method for operating a satellite positioning system (SPS) receiver, said method comprising: determining a first plurality of pseudoranges at a first time; determining a second plurality of pseudoranges at a second time which is after said first time; storing said first plurality of pseudoranges and storing said second plurality of pseudoranges; transmitting after said second time said first plurality of pseudoranges and said second plurality of pseudoranges.
2. A method as in claim 1 further comprising determining whether a predetermined type of event has occurred and transmitting said first plurality of pseudoranges and said second plurality of pseudoranges in response to determining that said predetermined type event has occurred.
3. A method as in claim 2 wherein said predetermined type of event is one of (a) a sensor detects a condition; or (b) a memory limit is reached; or (c) a predetermined number of pluralities of pseudoranges has been stored; (d) a predetermined period of time has lapsed since a last set of pseudoranges was transmitted; or (e) a command from an external source over a communication link.
4. A method as in claim 1 further comprising: receiving in said SPS receiver first SPS signals from which said first plurality of pseudoranges is determined; determining a first receipt time when said first SPS signals were received at said SPS receiver; receiving in said SPS receiver second SPS signals from which said second plurality of pseudoranges is determined; determining a second receipt time when said second SPS signals were received at said SPS receiver; transmitting said first receipt time and said second receipt time. WO 99/57576 PCT/US99/08085 -21
5. A method as in claim 4 further comprising: determining whether a predetermined type of event has occurred and transmitting said first plurality of pseudoranges and said second plurality of pseudoranges and said first receipt time and said second receipt time in response to determining that said predetermined type of event has occurred.
6. A method as in claim 5 wherein said predetermined type of event comprises a predetermined period of time which has lapsed since a last set of pseudoranges was transmitted.
7. A method as in claim 6 wherein said predetermined period of time can be varied.
8. A method as in claim 7 wherein varying said predetermined period of time causes an interval of time between said first plurality of pseudoranges and said second plurality of pseudoranges to be varied.
9. A method as in claim 4 wherein said first plurality of pseudoranges and said second plurality of pseudoranges are part of a series pluralities of pseudoranges which are determined and stored sequentially over time and then transmitted as a collection of data
10. A Satellite Positioning System (SPS) receiver comprising: a SPS RF (radio frequency) receiver which receives SPS signals; a processor coupled to said SPS RF receiver, said processor determining a plurality of pseudoranges from said SPS signals, wherein said processor determines a first plurality of pseudoranges from SPS signals received at a first time and determines a second plurality of pseudoranges from SPS signals received at a second time which is after said first time; a memory coupled to said processor, said memory storing said first plurality of pseudoranges and said second plurality of pseudoranges; WO 99/57576 PCTIUS99/08085 -22 a transmitter coupled to said memory, said transmitter transmitting said first plurality of pseudoranges and said second plurality of pseudoranges after said second time
11. A SPS receiver as in claim 10 wherein said transmitter transmits said first plurality of pseudoranges and said second plurality of pseudoranges in response to a predetermined type of event
12. A SPS receiver as in claim 11 wherein said SPS RF receiver receives first SPS signals from which said first plurality of pseudoranges is determined and said SPS RF receiver receives second SPS signals from which said second plurality of pseudoranges is determined and wherein a first receipt time when said first SPS signals were received is determined and stored in said memory and a second receipt time when said second SPS signals were received is determined and stored in said memory and wherein said transmitter transmits said first receipt time and said second receipt time
13. A SPS receiver as in claim 12 wherein said first receipt time and said second receipt time are determined from SPS signals
14. A SPS receiver as in claim 12 wherein said first receipt time and said second receipt time are determined from time signals received in a cell based communication signal which is received by a communication receiver which is coupled to said processor
15. A method of determining position from satellite positioning system (SPS) information, said method comprising: receiving a first plurality of pseudoranges which were determined from first SPS signals received at a first time; receiving a second plurality of pseudoranges which were determined from second SPS signals received at a second time which is after said first time; determining a first position from said first plurality of pseudoranges and determining a second position from said second plurality of WO 99/57576 PCT/US99/08085 -23 pseudoranges, wherein said first plurality of pseudoranges and said second plurality of pseudoranges were received in one transmission after said second time
16. A method as in claim 15 wherein said one transmission occurs after a predetermined type of event
17. A method as in claim 15 further comprising: storing a first plurality of pseudorange corrections for a corresponding first correction time and storing a second plurality of pseudorange corrections for a corresponding second correction time; determining said first position also from said first plurality of pseudorange corrections and determining said second position also from said second plurality of pseudorange corrections.']
