Positioning with the Global Positioning System [PDF]
International Astronomical Union Colloquium, 1980 AbstractThis year (1980) the U. S. Department of Defense has scheduled to have in operation six satellites of the Global Positioning System (GPS), which will provide timing and three dimensional position recovery potential to North America during certain segments of a day.

Research on Multi-sensor Fusion Localization for Autonomous-rail Rapid Tram
Kongzhi Yu Xinxi Jishu, 2022 Traditional positioning methods, such as GNSS (global navigation satellite system) and location base service, have large positioning error when applied in complex traffic scenarios such as like tunnels buildings and viaducts.

A Novel Deep Learning Approach to 5G CSI/Geomagnetism/VIO Fused Indoor Localization
Sensors, 2023 For positioning tasks of mobile robots in indoor environments, the emerging positioning technique based on visual inertial odometry (VIO) is heavily influenced by light and suffers from cumulative errors, which cannot meet the requirements of long-term ...

GeoNotes: A Location-based Information System for Public Spaces [PDF]
, 2002 The basic idea behind location-based information systems is to connect information pieces to positions in outdoor or indoor space. Through position technologies such as Global Positioning System (GPS), GSM positioning, Wireless LAN positioning ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,
