POSITION DETERMINATION USING MEASUREMENTS FROM PAST AND PRESENT EPOCHS
First Claim
Patent Images
1. A method for determining a navigation solution comprising:
- storing a first portion of information acquired from one or more sources in a first epoch, wherein the stored first portion of information includes non-pseudorange measurements for at least one of the sources and is not sufficient to compute a navigation solution; and
obtaining a second portion of information subsequent to the first epoch, which enables use of the stored first portion of information in computing the navigation solution, the second portion of information comprising position information from at least one source among the one or more sources.

17. An apparatus comprising:
-
a memory to store a first portion of information acquired from one or more sources in a first epoch, wherein the stored first portion of information includes non-pseudorange measurements for at least one of the sources and is not sufficient to compute a navigation solution; and a processing unit configured to obtain a second portion of information subsequent to the first epoch, which enables use of the stored first portion of information in computing the navigation solution, the second portion of information comprising position information from at least one source among the one or more sources. - View Dependent Claims (18)

19. An apparatus comprising:
-
means for storing a first portion of information acquired from one or more sources in a first epoch, wherein the stored first portion of information includes non-pseudorange measurements for at least one of the sources and is not sufficient to compute a navigation solution; and means for obtaining a second portion of information subsequent to the first epoch, which enables use of the stored first portion of information in computing the navigation solution, the second portion of information comprising position information from at least one source among the one or more sources.

20. A non-transitory computer-readable medium comprising instructions which, when executed by a processing unit, perform functions, the instructions comprising:
-
code to store a first portion of information acquired from one or more sources in a first epoch, wherein the stored first portion of information includes non-pseudorange measurements for at least one of the sources and is not sufficient to compute a navigation solution; and code to obtain a second portion of information subsequent to the first epoch, which enables use of the stored first portion of information in computing the navigation solution, the second portion of information comprising position information from at least one source among the one or more sources.
