Energy of a Satellite in a Circular Orbit01:11

Energy of a Satellite in a Circular Orbit

3.0K
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

5.5K
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...

Satellite Stem Cells and Muscular Dystrophy01:21

Satellite Stem Cells and Muscular Dystrophy

2.4K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Lewis Acids and Bases02:33

Lewis Acids and Bases

48.4K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Base Excision Repair01:54

Base Excision Repair

26.4K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Weak Base Solutions03:21

Weak Base Solutions

25.3K
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Summary

This study introduces a faster on-board orthorectification method using field-programmable gate arrays (FPGAs) and fixed-point arithmetic for rational polynomial coefficients (RPCs). The FPGA-based method is over 11,000 times faster than traditional PC implementations, enabling rapid satellite image processing.

Area of Science:

  • Remote Sensing
  • Geospatial Information Systems
  • Computer Engineering

Background:

  • Conventional rational polynomial coefficients (RPC)-based orthorectification is too slow for time-sensitive applications like disaster response.
  • Existing methods struggle to meet the demands for rapid satellite image processing.

Purpose of the Study:

  • To develop and validate a high-speed, on-board orthorectification method for satellite imagery.
  • To accelerate orthorectification processing speed using field-programmable gate arrays (FPGAs) and fixed-point (FP) arithmetic.

Main Methods:

  • Modified the RPC algorithm using fixed-point arithmetic.
  • Implemented the fixed-point RPC (FP-RPC) algorithm on an FPGA chip.
  • Developed three modules: parameter reading, coordinate transformation, and interpolation.

Main Results:

  • The FPGA-based FP-RPC method achieved a throughput of 675.67 Mpixels/s, over 11,000 times faster than a Matlab-based RPC method (61,070.24 pixels/s).
  • Achieved high accuracy with root-mean-square errors (RMSEs) below 0.5 pixels for both study areas (e.g., ΔI=0.35, ΔJ=0.30, ΔS=0.46 pixels).

Conclusions:

  • The proposed FPGA-based FP-RPC method significantly accelerates satellite image orthorectification.
  • This high-speed processing capability is crucial for timely responses in critical situations like disaster rescue and security operations.
