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 کاملReal-time Cycle Slip Detection and Repair for Network Multi-GNSS, Multi-frequency data processing
The GNSS community is experiencing a new era with the development of the multi-GNSS and multi-frequency industry. For high-precision GNSS data processing with the use of carrier phase measurements, quality control steps, such as, cycle slip detection and repair, are essential. With the correct detection and repair of the cycle slips, the carrier phase measurements will not be lumped by the unkn...
متن کاملAutomated 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...
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 کاملPrecise Point Positioning Using Triple GNSS Constellations in Various Modes
This paper introduces a new dual-frequency precise point positioning (PPP) model, which combines the observations from three different global navigation satellite system (GNSS) constellations, namely GPS, Galileo, and BeiDou. Combining measurements from different GNSS systems introduces additional biases, including inter-system bias and hardware delays, which require rigorous modelling. Our mod...
