Patent number: 9322926Abstract: According to certain aspects, the invention includes using acquisition channel results from a number of satellites to achieve composite weak acquisition. According to certain other aspects, the invention also includes solving for an improved position estimate and, with a sufficiently accurate, either initial or improved position estimate, also solving for GPS system time using a composite of acquired signals from a plurality of satellites. Within commonly experienced initial position and time uncertainties, the geometric range changes are fairly linear, which allows the point of convergence of ranges to solve for GPS position and subsequently for time with reasonable accuracy, which is the equivalent to obtaining frame sync without any data demodulation or preamble matching.Type: GrantFiled: March 30, 2012Date of Patent: April 26, 2016Assignee: QUALCOMM TECHNOLOGIES INTERNATIONAL, LTD.Inventors: Phanikrishna Sagiraju, Steven Gronemeyer

Patent number: 9287921Abstract: A method for soft frame synchronization in a navigational receiver is provided. A distance between bits of a sync pattern received by the navigational receiver and a known sync pattern is computed. A probability of detection value for the received sync pattern based on the distance is assigned. A confidence level for the received sync pattern using the probability of detection value is computed. The confidence level is compared with a confidence threshold. If the confidence level is greater than or equal to the confidence threshold, the confidence level of the received sync pattern is updated to generate a credibility of the sync pattern. The credibility of the received sync pattern is compared with a predetermined credibility value and, if the credibility of the received sync pattern is greater than or equal to the predetermined credibility value, synchronization of the navigational receiver is performed using the received sync pattern.Type: GrantFiled: August 12, 2014Date of Patent: March 15, 2016Assignee: Samsung Electronics Co., LtdInventors: Mohamed Youssef, Bruce McCullough, Steven Gronemeyer
