  1. 1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  2. 2. Monitoring deforestation in the Serranía de Chiribiquete in northern Colombian Amazon using time series analysis of satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Yuyang Qian; [2023]
    Keywords : Physical Geography and Ecosystem analysis; CCDC; Forest loss; Landsat; Sentinel-1; Change detection; NNP; FARC; Earth and Environmental Sciences;

    Abstract : Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring.

    Keywords : Precision Agriculture; Sentinel-1 SAR; Machine Learning; Winter Wheat; Harvest Prediction; RFI-filtering; Despeckling; Mathematics and Statistics;

    Abstract : Aiding farmers with their tremendous task of sustainably and cost-efficiently feeding the world is of utmost importance. Information technology plays a crucial role in supporting farmers and supplying them with accurate information about their crops. READ MORE

  4. 4. Flight dynamics multi-mission software development for optical link planning and execution

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Giacomo Dal Toso; [2023]
    Keywords : Generic Planning Tool; Visibility Service; Link Support Service; Visibility Windows; Flight Dynamics; Mission Planning;

    Abstract : The Generic Planning Tool (GPT) is a new software package being developed by the Flight Dynamics team at DLR. In an era where laser communications are becoming more and more relevant to data transmission for space missions, the GPT’s purpose is to compute highly accurate visibility windows and provide a wide variety of support information for both satellite-to-ground and inter-satellite links.

  5. 5. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Caroline Morin; [2023]
    Keywords : Optical remote sensing; Sentinel 2; Phosphorus; Total suspended matter; Turbidity;

    Abstract : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. READ MORE
