“…STAP has obvious advantages compared to the SOP. Without increasing the antenna elements, the DoF of interference suppression can greatly increase, and its interference suppression capability has a quality improvement [28]. In addition, STAP could mitigate the impact of non-ideal characteristic in antennas to anti-jamming.…”

Interference multipath is an important factor to affect the anti-jamming performance for the global navigation satellite system (GNSS) antenna array receiver. However, interference multipath must be considered in practical application. In this paper, the antenna array model for interference multipath is analyzed, and an equivalent model for interference multipath is proposed. According to the equivalent interference multipath model, the influence of interference multipath on anti-jamming performance is analyzed from the space only processing (SOP) and space-time adaptive processing (STAP). Interference multipath can cause loss of the degree of freedom (DoF) of SOP. Through analysis of the equivalent model and STAP mechanism, it further reveals how the STAP can solve the interference multipath. The simulation experiments prove that the equivalent model is effective, and the analysis conclusion is correct. This paper also points out that the interference bandwidth is wider and more taps in STAP are required, under the same experiment conditions.

“…Broadcast and precise ephemerides refer to distinct antenna reference points and clock reference signals which must be considered in the comparison (Montenbruck et al, 2018). While broadcast orbit and clocks are referred to the B3 phase center as provided by CSNO (CSNO-TARC, 2022) and the B3I signal (Xue et al, 2021), the IGS reference products are based on an ionosphere-fee B1I/B3I combination and the corresponding antenna phase centers of the IGS antenna model (igs14_2188.atx).…”

Following GPS, GLONASS, and Galileo, the Chinese BeiDou-3 system (BDS-3) started to provide navigation services for worldwide users in late 2019. Other than the second-generation BeiDou-2 system (BDS-2), which is mainly composed of satellites in geostationary Earth orbits (GEOs) and inclined geosynchronous orbits (IGSOs), BDS-3 is also comprised of 24 medium Earth orbit (MEO) satellites in three orbital planes that provide a global coverage. As the youngest global navigation satellite system (GNSS), BDS-3 makes use of highly advanced signal modulations and offers open service signals on five different frequencies. Along with a favorable signal-in-space range error (Montenbruck et al., 2020), which matches or even exceeds that of GPS, BDS-3 recommends itself as a highly competitive navigation system for worldwide users.Other than GPS and Galileo, which refer the satellite clock offset information in their broadcast navigation data to an ionosphere-free dual-frequency signal combination, BDS-2 and BDS-3 provide satellite clock offsets for the B3 frequency. Except for the uncommon case of a B3 single-frequency user, satellite group delays

“…compared BDS-3 and BDS-2 broadcast ephemeris [17] . In 2021, Xue et al mainly analyzed the influence of clock errors on BDS-3 SISRE base on the data from January 1 to December 31 in the year of 2019 [18] , and Chen et al (2021) made a further comparison between BDS-3 SISRE and BDS-2 SISRE [19] . However, the existing studies on SISRE for different types of satellites including MEO, GEO and IGSO after the official launch of BDS-3 are insufficient, especially for the comparison between BDS-3 and other systems.…”

Being the first mixed-constellation global navigation system, the global BeiDou navigation system (BDS-3) designs new signals, the service performance of which has attracted extensive attention. In the present study, the Signal-in-space range error (SISRE) computation method for different types of navigation satellites was presented. And the differential code bias (DCB) correction method for BDS-3 new signals was deduced. Based on these, analysis and evaluation were done by adopting the actual measured data after the official launching of BDS-3. The results showed that BDS-3 performed better than the regional navigation satellite system (BDS-2) in terms of SISRE. Specifically, the SISRE of the BDS-3 medium earth orbit (MEO) satellites reached 0.52 m, slightly inferior compared to 0.4 m from Galileo, marginally better than 0.57 m from GPS, and significantly better than 2.33 m from GLONASS. And the BDS-3 inclined geostationary orbit (IGSO) satellites achieved the SISRE of 0.90 m, on par with that of the QZSS IGSO satellites. However, the average SISRE of BDS-3 geostationary earth orbit (GEO) satellites was 1.15 m, which was marginally inferior to that of the QZSS GEO satellite (0.91m). In terms of positioning accuracy, the overall three-dimensional single-frequency standard point positioning (SPP) accuracy of BDS-3 B1C, B2a, B1I, and B3I gained an accuracy level better than 5 m. Moreover, the B1I signal exhibited the best positioning accuracy in the Asian-Pacific region, while the B1C signal set forth the best positioning accuracy in the other regions. Owing to the advantage in signal frequency, the dual-frequency SPP accuracy of B1C+B2a surpassed that of the transitional signal of B1I+B3I. Since there are more visible satellites in Asia-Pacific, the positioning accuracy of BDS-3 was moderately superior to that of GPS. The precise point positioning (PPP) accuracy of BDS-3 B1C+B2a or B1I+B3I converged to the order of centimeters, marginally inferior to that of the GPS L1+L2. However, these three combinations had a similar convergence time of approximately 30 minutes.
