A Novel Sampling Approach in GNSS-RO Receivers with Open Loop Tracking Method
Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...
متن کاملCalibration of Magnetometers with GNSS Receivers and Magnetometer-Aided GNSS Ambiguity Fixing
Magnetometers provide compass information, and are widely used for navigation, orientation and alignment of objects. As magnetometers are affected by sensor biases and eventually by systematic distortions of the Earth magnetic field, a calibration is needed. In this paper, a method for calibration of magnetometers with three Global Navigation Satellite System (GNSS) receivers is presented. We p...
متن کاملA Novel Residual Frequency Estimation Method for GNSS Receivers
In Global Navigation Satellite System (GNSS) receivers, residual frequency estimation methods are traditionally applied in the synchronization block to reduce the transient time from acquisition to tracking, or they are used within the frequency estimator to improve its accuracy in open-loop architectures. There are several disadvantages in the current estimation methods, including sensitivity ...
متن کاملA Concurrent Dual-Band Low Noise Amplifier for GNSS Receivers
In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...
متن کاملMultipath Mitigation Performance Comparison of Strobe Correlators in GNSS Receivers
This paper introduces effective methods of decreasing multipath errors by utilizing strobe correlators designed for GPS coarse-acquisition (C/A) code for future modernized signals including the BOC (n,n) modulation used for GPS L1C, Galileo E1 and the GLONASS new CDMA signal. The implementation and performance of different types of strobes are compared and discussed. The strobe concept is espec...
