This invention relates to a method and system for monitoring and enhancing the power of GPS P(Y) signals based on civilian signal tracking. The method employs a carrier tracking loop to stably track civilian satellite navigation signals, generating a local carrier with the same frequency and phase as the GPS satellite navigation digital signal. The GPS satellite navigation digital signal is then orthogonally mixed with the local carrier to output the in-phase branch signal u. I (n) and the orthogonal branch signal u Q (n); the in-phase branch signal u I (n), Orthogonal branch signal u Q (n) Perform low-pass filtering and incoherent integration respectively to obtain the average power P of the baseband signal in the in-phase branch. IB Average power P of baseband signal in orthogonal branch QB The average power P of the baseband signal in the same phase branch IB Average power P of baseband signal in orthogonal branch QB The power enhancement state of the current P(Y) signal is determined by comparing it with the weak-state power threshold of the in-phase branch, the strong-state power threshold of the in-phase branch, the strong-state power threshold of the quadrature branch, and the weak-state power threshold of the quadrature branch.

The present application discloses a kind of hibiscus compound extract, its preparation method and application.The composite extract includes hibiscus exosome, hibiscus traditional active ingredient, snowbank flower extract and microalgae extracellular polysaccharide, wherein the hibiscus exosome and hibiscus traditional active ingredient are simultaneously extracted from hibiscus raw materials by integrated extraction process.The preparation method includes raw material pretreatment, integrated extraction, separation and purification, synergistic compounding and post-processing, and two types of active substances are efficiently and synchronously obtained by optimizing solvent, temperature, time and purification parameters.The composite extract exhibits excellent anti-aging, anti-inflammatory and moisturizing effects in cosmetics, and has excellent effects of regulating intestinal flora and enhancing immunity in functional foods.The process produces significant synergistic effect by combining specific synergistic components, and the effect is much better than single component or simple mixture, realizing the maximization of plant resources and the synergistic promotion of efficacy.
