Abstract
A method of determining a GPS position fix. The method includes: (i) sampling received GPS signals and storing those samples; (ii) conducting preliminary processing of those GPS signal samples to determine the likelihood of being able to obtain a position fix during later, final processing of those GPS signal samples; and (iii) after step (ii), conducting final processing of those GPS signal samples to obtain a position fix.
Claims7
A method of determining a GPS position fix comprising the steps of:
- (i) sampling received GPS signals and storing those samples;
- (ii) conducting preliminary processing of those GPS signal samples to determine the likelihood of being able to obtain a position fix during later, final processing of those GPS signal samples;
- and
- (iii) after an intentional delay after step (ii), conducting final processing of those GPS signal samples or derivatives thereof obtained during step (ii) to obtain a position fix,
- wherein, upon a negative determination in step (ii), steps (i) and (ii) are repeated.
