A comparison is made of the sensitivities for detecting hydrogen with Pt-coated single ZnO nanorods and thin films various thicknesses (20–350 nm). The show a current response approximately factor 3 larger at room temperature upon exposure to 500ppmH2 in N2 than ZnO. power consumption both types sensors can be very small (in nW range) when using discontinuous coatings Pt. Once Pt coating becomes continuous, required operate increases μW range. optimum film thickness under our conditions was...
Abstract Ionospheric delay, as one of the largest error sources in radio propagation, can only be corrected for this using ionospheric delay correction model Global Navigation Satellite System (GNSS) single‐frequency users. In paper, 2021 geomagnetic storm event is selected, and based on measured data from GNSS observatory, perturbation ionosphere by analyzed, it found that response to has obvious differences characteristics time different latitude regions. The performance global map (GIM),...

Abstract The tropospheric delay acquired by the Global Navigation Position System (GPS) Precise Point Positioning (PPP) is continuous and steady, less affected rainfall. Water Vapor Radiometer (WVR) can provide real‐time meteorological parameters but more sensitive to high‐frequency information in troposphere. To explore use of WVR‐retrieved assist other geodetic techniques for atmospheric correction, from WVR co‐located GPS at Shanghai, Beijing, Kunming, Urumqi stations China are compared....
