Patent number: 9075141Abstract: The present invention uses a map database which is created with the view of optimization in terms of size and complexity, so that it can be easily embedded into a navigation chip. The optimized map database is referred to as a “mini-map” database. The mini-map database easily integrates with the position calculation routine. The algorithm for position calculation includes a map-matching component, which is referred to as the “mini-map-matching” (MMM) algorithm, which is implemented on the navigation chip. Application of the present invention includes any navigation system for vehicles and/or pedestrians. The navigation system may include an inertial sensor, such as a dead-reckoning (DR) sensor, for further improvement in calculated positional accuracy when satellite signals are degraded due to environmental factors.Type: GrantFiled: December 8, 2011Date of Patent: July 7, 2015Assignee: CAMBRIDGE SILICON RADIO LIMITEDInventors: Qutub Salman Syed, Jaime B. Colley, Stefan Witanis, Terence Douglas Macaulay

Patent number: 8954269Abstract: Methods and systems consistent with the present invention provide a host based positioning system. The host based positioning system includes a tracker hardware interface that connects to a dedicated hardware space vehicle tracker. The tracker hardware interface receives positioning information from the space vehicle tracker. The host based positioning system also includes a memory that includes a GPS library having a user interface, a tracker interface, and an operating system interface. A processor runs functions provided by the interfaces.Type: GrantFiled: August 23, 2010Date of Patent: February 10, 2015Assignee: CSR Technology Inc.Inventors: Clifford Yamamoto, Sebastian Nonis, Ashutosh Pande, Nikola Bulatovic, Stefan Witanis
