Claims39
A method comprising:
- storing a first portion of information acquired from one or more sources in a first epoch, wherein said stored first portion of information includes non-pseudorange measurements for at least one of said sources and is not sufficient to compute a navigation solution;
- and
- obtaining a second portion of information subsequent to said first epoch, enabling use of said stored first portion of information in computing said navigation solution.
A method comprising:
- storing a first portion of information acquired from one or more sources in a first epoch, wherein said stored first portion of information excludes information based on received satellite positioning system (SPS) signals and is not sufficient to compute a navigation solution;
- and
- obtaining a second portion of information subsequent to said first epoch, enabling use of said stored first portion of information in computing said navigation solution.
An apparatus comprising:
- a memory to store a first portion of information acquired from one or more sources in a first epoch, wherein said stored first portion of information includes non-pseudorange measurements for at least one of said sources and is not sufficient to compute a navigation solution;
- and
- a processing unit configured to obtain a second portion of information subsequent to said first epoch, enabling use of said stored first portion of information in computing said navigation solution.
An apparatus comprising:
- means for storing a first portion of information acquired from one or more sources in a first epoch, wherein said stored first portion of information includes non-pseudorange measurements for at least one of said sources and is not sufficient to compute a navigation solution;
- and
- means for obtaining a second portion of information subsequent to said first epoch, enabling use of said stored first portion of information in computing said navigation solution.
A 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 said stored first portion of information includes non-pseudorange measurements for at least one of said sources and is not sufficient to compute a navigation solution;
- and
- code to obtain a second portion of information subsequent to said first epoch, enabling use of said stored first portion of information in computing said navigation solution.
