Cycle Slip Detection and Correction for Precise Point Positioning
Over the last years precise point positioning (PPP) has been receiving more attention as it provides a cheaper way to achieve decimetre and centimetre precision levels when compared to the typical differential techniques. While differential techniques rely on two or more receivers to differentiate their observations and cancel out most errors, PPP only uses undifferenced observations from a sin...
متن کاملGPS Cycle Slip Detection and Correction at Measurement Level
Carrier phase measurements are much more precise than pseudorange measurements and can be used to achieve very accurate positioning solutions. However, carrier phase measurements require resolution of integer ambiguities before precise positioning can be achieved. The GPS receiver can keep track of the integer number of cycles as long as the receiver maintains lock to the satellite signal. Howe...
متن کاملInertial Aided Cycle Slip Detection and Identification for Integrated PPP GPS and INS
The recently developed integrated Precise Point Positioning (PPP) GPS/INS system can be useful to many applications, such as UAV navigation systems, land vehicle/machine automation and mobile mapping systems. Since carrier phase measurements are the primary observables in PPP GPS, cycle slips, which often occur due to high dynamics, signal obstructions and low satellite elevation, must be detec...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Automated cycle-slip correction of dual-frequency kinematic GPS data
In order to attain high precision positioning and navigation results with GPS, cycle slips must be correctly repaired at the data preprocessing stage. Over the past decade a number of methods have been developed to detect and repair cycle slips. These methods invariably require user intervention for problematic cycle slips in portions of data, tuning of input parameters to data, or introduction...
