The continuously available satellites of European Galileo currently reach more than 25. To explore the rationality and reliability of the l-band and satellite laser ranging(SlR) data processing strategies, we design the Galileo l-band, the SlR-only, and the combined l-band/SlR dynamic precise orbit determination(POD) strategies by using the normal equations(NEQs) stacking, and investigate their continuity and stability by employing the Galileo l-band data and SlR observations for the time span of the whole year of 2023, based on the Bei Dou/GNSS analysis center platform of Shandong University by using the modified Bernese GNSS Software Version 5.4. The orbital consistency of the l-band 1-day solution is the best with the Three-dimensional Root-Mean-Square(3D-RMS) values of 3.6 cm compared with the Center for Orbit Determination in Europe Multi-GNSS Experiment(COM) orbits, the corresponding values is 1.4 cm, 2.5 cm, and 2.3 cm in Radial, the Tangential, and the Normal(RTN) direction, respectively. While the SlR-only 9-day arc length is optimal with the RTN values of 5.3 cm, 30 cm, and 38.2 cm,as well as the 3D-RMS values of 48.9 cm. Encouragingly, the difference of the orbital accuracy between the combined l-band/SlR multi-day solution and the COM orbits is reduced by 0.5 cm and 0.9 cm, 0.6 cm and 1.2 cm in T-, and N-direction for the 3-and 5-day solution respectively. The corresponding values improve 0.7 cm and 0.9 cm, 1.4 cm and 1.8 cm for the 3-and 5-day orbital overlaps difference between the combined l-band/SlR and the l-band solution. Take the E09 satellite as a case study, the SlR-only orbital accuracy is regularly optimized as the multi-day arc lengthens and with the sites ***, the SlR residuals of its three types of orbits further demonstrate the positive contribution of SlR to the combination of the GNSS and SlR techniques.

The article addresses the output-feedback control issue for a class of multi-input multi-output(MIMO)uncertain nonlinear systems with multiple event-triggered mechanisms(ETM).Compared to previous event-triggering studies,this paper aims to trigger both the output and filtered *** nonlinear dynamics are approximated using fuzzy logic systems(FlSs).Then,a novel kind of state observer has been designed to deal with unmeasurable state problems using the triggered output *** sampled estimated state,the triggered output signal,and the filtered signal are utilized to propose an event-triggering mechanism that consists of sensor-to-observer(SO)and observer-to-controller(OC).An event-triggered output feedback control approach is given inside backstepping control,whereby the filter may be employed to circumvent the issue of the virtual control function not being differentiable at the trigger *** is testified that,according to the lyapunov stability analysis scheme,all closed-loop signals and the system output are ultimately uniformly constrained by our control ***,the simulation examples are performed to confirm the theoretical findings.
