Abstract
The evaluation of signal structure is an important phase of the signal structure design in the process of GPS modernization, Galileo and BDS construction. The new generation navigation signals of global navigation satellite system (GNSS) have the characteristics of diversification of signal structure, large bandwidth and complicated receiving method. Based on this, a new generation signal structure evaluation system (NGSSES) was proposed. The NGSSES is flexible to configure, and the bandwidth and sampling rate can up to 250 and 150 MHz, respectively. The output signals have the power of resolution of 0.5 dB. The performance of code and carrier tracking accuracy of BOC(14,2) under single channel and channel combining tracking methods, multipath of TMBOC(6,1,4/33) under matching and non-matching methods are evaluated using NGSSES. The anti-jamming performance of BOC(14,2) and AltBOC(15,10), compatibility of BDS B1 BOC(14,2) and GPS L1M BOC(10,5) are also evaluated using NGSSES. The experimental results verified the feasibility and effectiveness of NGSSES.
