Unlike dual-frequency users who reduce ionospheric delay by using the ionospheric elimination combination, SF users need to use external data sources such as the global broadcast ionospheric model to reduce the ionospheric delay. Moreover, with the arrival of 25th solar cycle, the increasing of solar activity level is further affecting the performance of ionospheric correction. To conduct a comprehensive evaluation of ionospheric models during the 25th solar cycle, we assessed four models: three operational models recommended by interface control documents (BDGIM, GPS Klobuchar, and NeQuick-G), as well as the NTCM-G model, which is based on Galileo broadcast coefficients. Our analysis utilized datasets from both continental and oceanic regions over the period from January 2020 to December 2023. For continental regions, the GNSS TEC data obtained from 33 individual monitoring stations are used as a reference data source. For oceanic regions, the TEC data obtained from JASON-3 altimeters are selected as the reference value. According to the comparison between JASON-3 TEC dataset and TEC dataset obtained from the four tested ionospheric models, the assessment demonstrates that the performances of tested models are strongly affected by solar activity. Specifically, BDGIM, Klobuchar, NTCM-G and NeQuick-G exhibit the RMS values of 4.36, 5.67, 5.06 and 5.84 TECU in low solar activity in 2020, and 9.99, 13.44, 10.64 and 9.50 TECU in high solar condition in 2023, respectively. In addition, as the validation against International GNSS Service (IGS) final Global Ionospheric Maps (GIMs) products shows, the average global RMS values of BDGIM, Klobuchar, NTCM-G and NeQuick-G are 5.23, 8.43, 4.95 and 6.22 TECU, respectively. BDGIM performs the best in low latitudes, NeQuick-G shows the highest accuracy in the northern mid to high latitude regions, NTCM-G exhibits the best performance in southern mid and high latitudes, and Klobuchar performs the worst across all latitudes.</div></div>","PeriodicalId":50850,"journal":{"name":"Advances in Space Research","volume":"75 10","pages":"Pages 7654-7667"},"PeriodicalIF":2.8,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143906864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we obtain the ground deformation rate field information of Yan’an New Area, Shaanxi Province, based on the Small Baseline Subsets-Interferometric Synthetic Aperture Radar (SBAS-InSAR) technology, and analyze the causes of subsidence in the study area using multi-source remote sensing data; combining the optical image and exponential model, we detect and identify the engineering landslides in Yan’an New Area. In addition, we considered the effects of stratigraphic lithology, filling depth, surface temperature, precipitation and soil moisture on landslide deformation, and combined the Particle Swarm Optimization-Back Propagation (PSO-BP) neural network model to predict the time-series deformation values of landslides. The study shows that: (1) the ground settlement in Yan’an New Area after the mountain filling and city building project is mainly distributed in the filling area, and the radar line-of-sight deformation rate of Yan’an New Area from 2019 to 2022 is −44.92 ∼ 19.24 mm/a, mainly distributed in the center of Qiaoergou, Gaojiagou, and Tanyaogou area.

In addition to precipitation, changes in soil moisture and surface temperature can accelerate the subsidence of engineered landslides.

A decisive novelty was added by introducing the curvature of the mirrors, that allows the reconstruction of the observed light curve given the attitude of the satellite. Measurements of the Ajisai’s light flux have been acquired using a high frequency (5/10 kHz) linear-detection optical photometry technique from the MéO telescope at Grasse station on the Plateau de Calern site of Observatoire de la Côte d’Azur. A procedure to extract individual flashes from the observed flux and identify the associated mirror on which the reflection occurred has been developed. The analysis of the observed flashes confirmed the validity of the model and allowed us to reconstruct the attitude of the satellite. The satellite rotation has been expressed as a function of the rotation spin axis, the rotation period and the rotation angle around the axis. A method to determine each parameter directly from single pass observations is proposed to fully constrain the satellite attitude using photometry.

The influence of multipath on float precise point positioning (PPP) solutions is pronounced, with positioning discrepancy in the east, north, and vertical components of 2.4 mm, 0.6 mm, and 2.7 mm, respectively, even for 24-hour solution. The shortening 4-hour solutions further magnifies the impact of multipath correction, with discrepancy of 6.4 mm, 3.2 mm, and 9.3 mm. Accuracy of float PPP solutions is improved with multipath hemispherical map (MHM) correction, with more than 87.1 % of stations being better consistent with IGS products. In addition, MHM correction improves the ambiguity fixing rate by 1.1 %, 3.6 %, and 5.8 % for 24-hour, 8-hour, and 4-hour solutions, respectively. The advantages of MHM correction are also validated by the stacking solutions, and the white noise and colored noise for the 8-hour and 4-hour fixed PPP could be significantly reduced.

This paper investigates the complex optimization problem of multi-impulse orbital transfer involving a chaser and a target. The chaser is subject to constraints on impulse magnitude and time, while the target may experience uncertain disturbances, causing it to deviate from the nominal orbit. The complexity of this problem imposes a significant computational burden on numerical methods, making it challenging for spacecraft to autonomously plan trajectory transfers in real time. To mitigate this burden, we propose a robust, fast, and autonomous algorithm for the optimization challenge, which can rapid plan transfer trajectories. Even if the terminal conditions suddenly change, our algorithm can quickly adjust the trajectory based on observed states without the need to completely re-plan. The algorithm comprises an intelligent trajectory generator and a Lambert transfer algorithm. The intelligent generator is based on a reinforcement learning (RL) method called contrastive-pre-trained Reinforcement Learning (CPRL), which emulates human learning habits to avoid the temporal credit assignment with long time horizons and sparse rewards during the training phase. When the chaser reaches an admissible range, determined by the impulse constraints and geometric relations of the conic curve, the algorithm adopts the Lambert transfer to complete the mission. Compared to traditional genetic and particle swarm algorithms, our method achieves a significant improvement in computational speed. Even with deviations, the average mission success rate remains at 96.8%.

This has led to various studies aimed at utilizing RTM techniques to quantify and map a range of biophysical and biochemical properties at different scales. Most literature reviews have predominantly focused on 1D models, such as PROSAIL, overlooking the more robust 3D models. This paper provides a detailed systematic review on the progress, gaps, and opportunities associated with both 1D and 3D RTM models in the context of remote sensing of terrestrial biomes. The review reveals a skewed distribution of research efforts between the Global North and South, with a significant concentration of studies conducted in the United States, China, and Germany, while fewer investigations have been conducted in Africa. Furthermore, most studies have primarily utilized MODIS and Landsat sensors, focusing on plant attributes such as Leaf Area Index (LAI) and chlorophyll content. These studies have been predominantly conducted in grassland and forest landscapes. Overall, the findings indicate that PROSPECT and PROSAIL have been the most popular models over the past two decades. In the realm of 3D models, the Discrete Anisotropic Radiative Transfer (DART) and Forest Light Interaction Model (FLIGHT) models have been the most popular. These models have been primarily utilized through the look-up table (LUT) method, followed by the hybrid approach combining machine learning and RTMs. Understanding both 1D and 3D models offers an opportunity to assess the current state of research and identify future opportunities in the application of radiative transfer modeling for ecological remote sensing.
