Method And Apparatus For Determining An Error Estimate In A Hybrid Position Determination System

View page
US Patent:
6420999, Jul 16, 2002
Filed:
Oct 26, 2000
Appl. No.:
09/697781
Inventors:
Alkinoos Vayanos - San Diego CA
Assignee:
Qualcomm, Inc. - San Diego CA
International Classification:
G01S 502
US Classification:
34235703, 34235702, 701214, 701215
Abstract:
A method and apparatus that allows correlations between a selected parameter and the error in a pseudo range measurement to be exploited. A database is established in which the amount of error estimated for particular pseudo range measurements to a beacon is maintained. Clusters are defined. Each cluster is associated with a range of values for the selected parameter. Pseudo range measurements are then associated with a particular cluster based upon the value of the selected parameter at the time (or proximate to the time) the pseudo range measurement was taken. As more estimates of the pseudo range measurements are made, the size of the clusters (i. e. , the range of values of the selected parameter) can be reduced. Due to the correlation between the selected parameter and the errors in the pseudo range measurements, reducing the size of the clusters reduces the variance of the error estimates. The mean value of the error estimates is used to correct the error in future pseudo range measurements.

Method And Apparatus For Determining Location Using A Coarse Position Estimate

US Patent:
6429809, Aug 6, 2002
Filed:
Jan 30, 2001
Appl. No.:
09/773207
Inventors:
Alkinoos Vayanos - San Diego CA
Peter Gaal - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04B 7185
US Classification:
34235703, 34235702
Abstract:
Corrections to a coarse position estimate of the pseudorange receiving device are made based upon knowledge of the amount of error present in inaccurate information (e. g. , the old Almanac and/or Ephemeris) used to estimate the coarse position.

Method And Apparatus For Locating Gps Equipped Wireless Devices Operating In Analog Mode

View page
US Patent:
6430415, Aug 6, 2002
Filed:
Mar 29, 1999
Appl. No.:
09/280337
Inventors:
Parag A. Agashe - San Diego CA
Samir S. Soliman - San Diego CA
Alkinoos Hector Vayanos - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04Q 720
US Classification:
455456, 455 671, 3423571, 34235708
Abstract:
An apparatus and method for locating a remote station operating in analog mode, and that may not have a sense of network time, using an inverted GPS approach. The invention also enables remote stations operating in analog mode that do not know true GPS time to determine their own location. A time stamp, reflecting the approximate time a satellite range measurement is made, is assigned to the measurement at either the remote station or elsewhere in the network. The difference between true GPS network time and the measurement time is treated as a variable âerrorâ in measurement, the length of which is unknown. This variable error is determined and used in determining the physical location of the remote station.

Method And Apparatus For Providing Accurate Position Estimates In Instances Of Severe Dilution Of Precision

View page
US Patent:
6505122, Jan 7, 2003
Filed:
Aug 3, 2001
Appl. No.:
09/922472
Inventors:
Alkinoos H. Vayanos - San Diego CA
Assignee:
Qualcomm, Incorporated - San Diego CA
International Classification:
G01S 500
US Classification:
701213, 34235701
Abstract:
Techniques for providing an improved position estimate for a device in instances of relatively large dilution of precision. In a method, position estimates for a number of transmitters (e. g. , GPS satellites and/or base stations) and a set of initial measurements (e. g. , pseudo-ranges) are initially received. An Update Vector for a current device position estimate is computed. Non-convergence of the current device position estimate toward a target position estimate is detected and, if true, the Update Vector is adjusted (e. g. , reduced in magnitude by a scaling factor) to increase the likelihood of convergence to the target position estimate. The current device position estimate is then updated based on the (possibly adjusted) Update Vector. Non-convergence may be detected based on the number of iterations performed without reaching the target position estimate and/or phase reversal in two consecutive Update Vectors. The scaling factor may be increased with each detected event indicative of non-convergence.

Method And Apparatus Providing Improved Position Estimate Based On An Initial Coarse Position Estimate

View page
US Patent:
6570530, May 27, 2003
Filed:
Jun 11, 2001
Appl. No.:
09/878934
Inventors:
Peter Gaal - San Diego CA
Alkinoos Vayanos - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
G01S 514
US Classification:
34235702, 34235706
Abstract:
Techniques for determining the location of a device based on an initial coarse position estimate for the device, which is derived based on initial (less accurate) estimates of the position of a plurality of transmitters. In one method, the coarse position estimate for the device and revised (more accurate) position estimates for the transmitters are received. A revised position estimate for the device is initialized (e. g. , to the coarse position estimate). An update vector is next computed based on the initial and revised position estimates for the device and the initial and revised position estimates for the transmitters. The revised position estimate for the device is then updated based on the update vector. The computation for the update vector and the updating of the revised position estimate for the device can be repeated a number of times to achieve a more and more accurate estimate.

Peter Gaal - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04B 7185
US Classification:
34235706, 34235702

Method And Apparatus For Estimating Velocity Of A Terminal In A Wireless Communication System

View page
US Patent:
6718174, Apr 6, 2004
Filed:
Oct 26, 2001
Appl. No.:
10/044194
Inventors:
Alkinoos Vayanos - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04Q 720
US Classification:
4554561, 342104, 34235705
Abstract:
Techniques to estimate the velocity of a terminal in a wireless communication system. Movement by the terminal results in a Doppler shift in the frequency of each transmitted signal received at the terminal. In one method, the positions of the terminal, a base station, and each of two or more satellites are initially determined. A residual rate of change of pseudo-range may also be determined for each satellite, e. g. , based on (1) an estimated baseband frequency error that includes the Doppler frequency shift due to the terminals movement and (2) an estimated Doppler frequency shift due to movement by the satellite. A set of equations is then formed based on the determined positions of the terminal, the base station, and the satellites and the determined residual rates of change of pseudo-ranges for the satellites. The velocity of the terminal may thereafter be estimated based on the set of equations.

Transport Format Combination Selection For Compressed Mode In A W-Cdma System

View page
US Patent:
6747958, Jun 8, 2004
Filed:
Nov 13, 2001
Appl. No.:
09/993381
Inventors:
Alkinoos Hector Vayanos - San Diego CA
Serge Willenegger - San Diego CA
Josef Blanz - Munich, DE
Assignee:
Qualcomm, Incorporated - San Diego CA
International Classification:
H04J 1300
US Classification:
370252, 370335, 370342
Abstract:
Techniques for determining valid (i. e. , supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that âTFC qualificationâ may be accurately performed. In a first scheme, Tx_power_requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative âbinsâ that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.
