To enhance the performance of location estimation in wireless positioning systems, the geometric dilution of precision (GDOP) is widely used as a criterion for selecting measurement units.Since GDOP represents the geometric effect on the relationship between measurement error and positioning determination error, the smallest GDOP of the measurement
Abstract Historically, the Latin American region presents evident social and educational inequalities that are represented in the educational trajectories of its youth populations; conditions that seem to be exacerbated in a pandemic.The objective of this text is to analyze the situation of secondary education in Latin America and in Argentina, in
With the development of science and technology, modern communication scenarios have put forward higher requirements for passive location technology.However, current location systems still use manual scheduling methods and cannot meet the current mission-intensive and widely-distributed scenarios, resulting in inefficient task completion.To address
This paper presents an orbit-to-ground model for efi live spade the atmospheric entry of ChipSats, gram-scale spacecraft that offer unique advantages over their conventionally larger counterparts.ChipSats may prove particularly useful for in-situ measurements in the upper atmosphere, where spatially and temporally varying phenomena are especially d
For decades, the armed conflict in Colombia has profoundly impacted across various domains, causing psychosocial, economic, environmental, political, and moral damages throughout the country.One of the most affected sectors has been education, which involves all stakeholders within the educational system, particularly teachers who have directly or
