Types of Global Positioning System Surveys

110
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...

Introduction to Global Positioning System

128
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,...

Energy of a Satellite in a Circular Orbit

2.4K
Thousands of artificial satellites orbit the Earth every day at various distances from the Earth. Satellites that orbit the Earth below an altitude of 1,600 km are considered to be orbiting in low-Earth orbit (LEO). Research satellites and Earth observation satellites are usually placed in LEO, and mostly orbit the Earth in elliptical orbits. Navigation satellites are placed in medium-Earth orbit (MEO), ranging from 2,000 km to 36,000 km from the surface of the Earth. Meanwhile, communication...

Circular Orbits and Critical Velocity for Satellites

3.0K
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.
Nicolaus Copernicus (1473-1543) first suggested that the Earth and all other planets orbit the Sun in...

Errors in Global Positioning System01:26

Errors in Global Positioning System

101
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,...

Area of Science:

  • Space technology
  • Animal ecology
  • Internet of Things (IoT)

Background:

  • The International Cooperation for Animal Research Using Space (ICARUS) satellite IoT system was launched in 2020.
  • Observing animal life, including migration, conditions, and mortality, is crucial for conservation and ecosystem health.
  • Existing low-power wide-area networks (LPWANs) face challenges in space communications.

Purpose of the Study:

  • To detail the system design of the ICARUS satellite IoT system.

  • To address limitations of conventional LPWANs in space-based animal tracking.

Main Methods:

  • Utilizing miniature on-animal sensors ('wearables for wildlife') to collect environmental and health data.
  • Developing and implementing random-access, very-low-power, wide-area networks (RA-vLPWANs) for global data transmission.

Main Results:

  • RA-vLPWANs enable uncoordinated multiple access at very-low-signal power and low signal-to-noise ratios.
  • The ICARUS system effectively transmits artificially intelligent summaries of animal and environmental data globally.
  • The system overcomes limitations of traditional LPWANs for space communication.

Conclusions:

  • The ICARUS system represents a significant advancement in using satellite IoT for wildlife research and conservation.
  • RA-vLPWANs are a viable solution for low-power, long-range IoT communication in space.
