Processing of Space Surveillance Observations [PDF]
, 2021 This thesis covers the processing of different types of space surveillance measurements. The emphasis is on the initial build-up of a catalogue. Most experiments focus on the identification of objects from pairs of observations by testing whether these two observations could originate from the same object.

AN ANALYSIS OF THE INFLUENCE OF THE NUMBER OF OBSERVATIONS IN A RANDOM FOREST TIME SERIES CLASSIFICATION TO MAP THE FOREST AND DEFORESTATION IN THE BRAZILIAN AMAZON [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Remote sensing has been an essential tool in combating deforestation. However, the ever-rising deforestation rates require new remote sensing techniques. This paper presents a study to determine the effects on the accuracy of the data analysis of varying

LEO Object’s Light-Curve Acquisition System and Their Inversion for Attitude Reconstruction
Aerospace, 2020 In recent years, the increase in space activities has brought the space debris issue to the top of the list of all space agencies. The fact of there being uncontrolled objects is a problem both for the operational satellites in orbit (avoiding collisions)

Methods of validation of the ballistic structure of space surveillance system orbital segment
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019 Space activity brought about the space debris problem that constitutes a threat to active spacecraft. Nowadays the most efficient way of spacecraft protection against space debris is choosing the appropriate orbit parameters to prevent collisions of ...
