چکیده
Abstract In recent years, we have witnessed a growing demand for GNSS receiver customization in terms of modification signal acquisition, tracking, and processing strategies. Such demands may be addressed by software-defined receivers (SDRs) which refers to an ensemble hardware software technologies allows re-configurable radio communication architectures. The crux the SDRs is replacement components through modules. this paper, assess quality observables acquired SDR against selected u-blox low-cost receiver. following, investigate performance level single point positioning that reached with ultra-low-cost compare it assessment revealed comparable carrier-to-noise density ratio significant out-performance over code pseudorange noise. experimentation domain proved offer position solution three-dimensional standard deviation error at 5.2 m mode noticeably poorer accuracy as compared results demonstrate there still room improvement.

Development and Positioning Accuracy Assessment of Single-Frequency Precise Point Positioning Algorithms by Combining GPS Code-Pseudorange Measurements with Real-Time SSR Corrections
We have developed a suite of real-time precise point positioning programs to process GPS pseudorange observables, and validated their performance through static and kinematic positioning tests. To correct inaccurate broadcast orbits and clocks, and account for signal delays occurring from the ionosphere and troposphere, we applied State Space Representation (SSR) error corrections provided by t...
متن کاملStudy and analysis of Differential GNSS and Precise Point Positioning
The Global Positioning system (GPS) is used for navigation and associated tasks in wide variety of applications. One of the primary modes of GPS operation is differential GPS. Differential GPS allows more accurate positioning than stand-alone GPS. Many new applications are possible because of the increased accuracy obtained through differential GPS. In this paper the techniques and methods of d...
متن کاملPerformance assessment of GPS/GLONASS single point positioning in an urban environment
In signal-degraded environments such as urban canyons and mountainous area, many GNSS signals are either blocked or strongly degraded by natural and artificial obstacles. In such scenarios standalone GPS is often unable to guarantee a continuous and accurate positioning due to lack (or the poor quality) of signals. The combination of different GNSSs could be a suitable approach to fill this gap...
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...

Dual-frequency Global Positioning System (GPS) Real-time Kinematics (RTK) has been proven in the past few years to be a reliable and efficient technique to obtain high accuracy positioning. However, there are still challenges for GPS single-frequency RTK, such as low reliability and ambiguity resolution (AR) success rate, especially in kinematic environments. Recently, multi-Global Navigation S...
