Errors in Global Positioning System01:26

Errors in Global Positioning System

370
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Azimuths and Bearings01:19

Azimuths and Bearings

753
Azimuths and bearings are essential concepts in surveying, providing methods to express the direction of a line relative to a meridian. Azimuths refer to the clockwise angle measured from the north end of a reference meridian to the given line, ranging from zero to 360 degrees. This method gives a comprehensive directional reference within a full 360-degree circle, making it a straightforward way to communicate direction in various fields, including navigation, cartography, and...

Introduction to Global Positioning System

629
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Types of Global Positioning System Surveys

389
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

What is a Sensory System?01:31

What is a Sensory System?

101.7K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

423
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Aging Research

Background:

  • The brain's navigation circuit, involving place and grid cells, is well-understood through cellular and human research.
  • Spatial navigation relies on complex computations within dedicated neuronal systems.

Purpose of the Study:

  • To review how cognitive aging affects navigational computations across species.
  • To explore the relationship between aging, spatial navigation, and memory.
  • To identify potential early markers of neurodegeneration.

Main Methods:

  • Review of emerging evidence from rodents, non-human primates, and humans.
  • Analysis of behavioral and neuroimaging research on cognitive aging and navigation.
  • Integration of findings on spatial perception, memory, and behavior.

Main Results:

  • Navigational deficits in aging are not solely explained by general learning and memory impairments.
  • Aging affects different navigational computations unevenly, showing no uniform decline.
  • Navigational deficits may serve as sensitive indicators of impending pathological brain changes.

Conclusions:

  • Cognitive aging uniquely impacts spatial navigation systems.
  • Spatial navigation decline can be an early sign of neurodegenerative disorders.
  • Behavioral and neural markers of spatial navigation hold clinical potential for early diagnosis.
