Filed:

Apr 15, 2010

Appl. No.:

12/761323

Inventors:

Michael O'Shea - Rancho Palos Verdes CA, US

Assignee:

Abalta Technologies, Inc. - Torrance CA

International Classification:

G01C 21/00

US Classification:

701400, 73178 R, 738659

Abstract:

A testing system is described. The testing system is adapted to evaluate navigation systems. The testing system includes: a recording system adapted to collect and record signals received and interpreted by a navigation system during field operation; a time-synchronized database adapted to receive and store data representing the signals collected and recorded by the recording system: wherein the stored data is able to be used to test operation of one or more navigation systems under test. A method of testing navigation systems includes: gathering data that would be received and interpreted by a navigation system during field operation, wherein the gathered data includes data associated with received radio signals; storing gathered data in a time-synchronized database; and using the stored data to test the operation of one or more navigation systems. A system adapted to test navigation systems includes: a recording system; a playback system; and a simulation system.

Appl. No.:

9/716489

Inventors:

Michael J. O'Shea - Chicago IL

Assignee:

Navigation Technologies Corporation

International Classification:

G06F16500

US Classification:

701211

Abstract:

A maneuver generation program for a computer-based navigation system. The navigation system provides a user with a series of maneuvering instructions to go from a first location to a second location in a geographic area. The series of maneuvering instructions are derived from a list of data entities that represent a route from the first location to the second location. The list of data entities includes data that represent a plurality of locations along the route at which maneuvering instructions may be provided. The maneuver generation program determines one and preferably no more than one maneuver type selected from a predetermined plurality of maneuver types for each location of the plurality of locations along the route. The maneuver generation program performs a series of tests upon data corresponding to each location. Each of the plurality of maneuver types is characterized by a unique set of tests selected from a predetermined superset of tests.
