A method to realize NAVSOP by utilizing GNSS authorized signals
نویسندگان
چکیده
Navigation via signals of opportunity (NAVSOP) is able to realize positioning by making use hundreds different that are all around us. A method NAVSOP for low earth orbit (LEO) satellites proposed in this paper, which the global navigation satellite system (GNSS) authorized utilized as signal (SOP). At first, carrier recovery technique studied under premise pseudo-code unknown. Secondly, a based on characteristics Doppler frequency shift recognize satellites. Thirdly, extended Kalman filter (EKF) estimate orbital parameters using phase measurements. Finally, evaluated generated data simulator. The simulation results show can successfully GNSS signals.

In this study, a new method of signal tracking technique in Global Navigation Satellite System (GNSS) is proposed. It is based on a combination of the autocorrelation function (ACF) with another cross correlation function in order to eliminate or reduce the power of the side peaks in ACF of Binary Offset Carrier (BOC) modulated signals. These types of modulated signals are adopted by both GNSSs...

متن کاملA Carrier Estimation Method Based on MLE and KF for Weak GNSS Signals
Maximum likelihood estimation (MLE) has been researched for some acquisition and tracking applications of global navigation satellite system (GNSS) receivers and shows high performance. However, all current methods are derived and operated based on the sampling data, which results in a large computation burden. This paper proposes a low-complexity MLE carrier tracking loop for weak GNSS signals...
