International Classification:

G01S 3/14

US Classification:

34235702, 34235713

Abstract:

The present invention provides methods and systems that enable a mobile navigation receiver to accurately determine its trajectory with non-current ephemeris in stand-alone mode. In an embodiment, the receiver computes the position for the same location using non-current ephemeris and current ephemeris at different time instances. The receiver then determines a position correction by finding the difference between these two computed positions, and applies this correction to the trajectory generated with non-current ephemeris to obtain a more accurate trajectory. In another embodiment, the receiver computes an initial position of the receiver using non-current ephemeris and finds the difference between the computed initial position and an accurate approximation of the initial position. The receiver then shifts the subsequent receiver trajectory computed using non-current ephemeris by the difference to obtain a more accurate trajectory.

International Classification:

US Classification:

701400, 34235764, 34235766

Abstract:

Provided herein are methods and systems for efficient communication between a server and a client in an assisted navigation system. In one or more embodiments, the client, e. g. , a GPS receiver, receives a set of parameters for a satellite from the server via a wireless or wired connection. The set of parameters includes a force parameter, initial condition parameters and time correction coefficients for the satellite. The receiver uses the received parameters in a numerical integration to compute the position of the satellite at a desired time. The set of parameters needed for the integration is small compared to current methods which require sending more data to the client. Thus these parameters require less communication resources to transmit. To further reduce the amount of data that needs to be transmitted, reference parameters may be subtracted from the original parameters before transmission from the server. The receiver is able to reconstruct the original parameters from the received parameters and the identically computed reference parameters.

Inventors:

Wentao Zhang - Cupertino CA, US

Assignee:

Marvell International Ltd. - Hmailton

International Classification:

G01S 19/35

US Classification:

34235775

Abstract:

In embodiments of sync feedback for time to first fix (TTFF), satellite data signals are received from which a geographic position of a positioning-system device can be determined. The satellite data signals each include a time reference and ephemeris data that indicates an orbital position of a satellite. A sync feedback is generated that includes a time-free position fix determined from a satellite data signal before bit sync and/or frame sync of the satellite data signal are obtained. The sync feedback is then utilized as a feedback input to determine the bit sync and/or the frame sync of the satellite data signal.

Appl. No.:

12/917989

Inventors:

Wentao Zhang - Cupertino CA, US
Victor Lin - Fremont CA, US

Assignee:

Marvell International Ltd. - Hamilton

International Classification:

G06F 15/00

US Classification:

702150

Abstract:

In a method of implementing a positioning system a buffer is configured to store a buffer record for each of a plurality of position fixes determined by the receiver and a database is configured to store a database record for each of the position fixes. Buffer records are accumulated, with each buffer record corresponding to one of the position fixes determined by the receiver. A first threshold position near an area in which a degradation event occurs is identified and recorded in a first database record. A second threshold position near the area is identified in a second database record. The second threshold position is indicated by one of the position fixes outside of the area and is proximate to a position at which the degradation event ends.
