The GPS system consists of 3 segments - the space segment containing 30 satellites in orbit, the control segment that monitors the satellites from ground stations, and the user segment which are the GPS receivers. GPS is now used widely for navigation, tracking, mapping, timing applications in transportation, vehicles, military, agriculture, tourism, wildlife monitoring and more.
The Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information to receivers on Earth and in space. GPS uses a constellation of at least 24 satellites that orbit Earth. Receivers triangulate their position by calculating distances to four or more satellites, and can determine location to within a few meters. GPS has both military and civilian uses, including navigation, tracking shipments, surveying land, and guiding farm equipment. It is free for civilian use and maintained by the U.S. Department of Defense.
The Global Positioning System (GPS) consists of three segments - the control segment, space segment, and user segment. The control segment monitors the satellites and ground stations. The space segment is made up of 24 satellites that orbit the Earth. The user segment includes all GPS receivers on Earth. GPS uses trilateration to determine the precise position of receivers by calculating distances to multiple satellites. Sources of error include clock errors, atmospheric delays, and multipath interference. Error correction techniques like differential GPS improve accuracy. GPS has many applications including navigation, mapping, and timing systems. Its accuracy and uses are continuing to improve in the future.

The document discusses a colloquium presentation on diamond chips. Diamond chips are manufactured from diamond structured carbon wafers and use carbon nanotubes as their major component. To make diamond conductive for electronics applications, it must be doped with elements like boron or nitrogen. Carbon nanotubes have excellent electrical and thermal properties and high strength. They allow for smaller, faster components that can operate at high temperatures. While diamond chips provide advantages over silicon, their production is more expensive and doping is more difficult due to diamond's structure. Overall, the presentation suggests that carbon chips may replace silicon in electronics in the future.

Brain fingerprinting is a technique that uses EEG to measure electrical brain wave responses to stimuli presented on a computer in order to determine if a person has specific information stored in their brain. It works by presenting probes, targets, and irrelevant stimuli and measuring brain waves like P300 responses. The brain waves are analyzed using algorithms to determine if information is present or absent. It has been used in criminal cases and national security screenings with a reported 100% accuracy rate. However, it cannot determine how the information was acquired and may not work if the suspect has been exposed to the same information from other sources.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors

Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

3. INTRODUCTION
GPS is a network of orbiting satellites that send
precise details of their position in space back
to earth.
The signals are obtained by GPS receivers ,such
as navigation devices and are used to calculate
the exact position , speed and time at the
vehicles location.

The History of GPS
7. How does GPS work?
THE MORE SATELLITES THE GPS CAN “SEE”, THE MORE
ACCURATE IS YOUR READINGS.
THE GPS MUST “SEE” THE SATELLITES, SO IT DOES NOT WORK
WELL IN THE DENSE FOREST, INSIDE CAVES, UNDERWATER, OR
INSIDE BUILDINGS.
STATIONS ON EARTH, AND A GPS RECEIVER,
THE DISTANCES BETWEEN EACH OF THESE
POINTS CAN BE CALCULATED.
THE DISTANCE CALCULATION BASED ON THE
AMOUNT OF TIME IT TAKES FOR A RADIO
SIGNAL TO TRAVEL BETWEEN THESE POINTS.
USING SATELLITES IN THE SKY, GROUND
ALLOWS THE GPS RECEIVER TO KNOW WHERE
YOU ARE, IN TERMS OF LATITUDE AND
LONGITUDE, ON THE EARTH..

to 12hrs and these orbits are equally spaced with 60
degrees apart and at an inclination angle of 55 degrees
in equator.
10. Control segment
The control segment comprises of 5 ground stations located on equator.
(4-monitor and 1-master station)
Monitor stations measure the distances of the overhead satellites every
1.5 seconds and send the corrected data to master station.
In master station the satellite orbit, clock performance and health of the
satellite are determined and determines whether repositioning is required.
This information is sent back to the satellites using ground antennas.
11. USER SEGMENT
The user segment consists of all earth –based GPS
The user segment is totally user community , both
receivers.
civilian and military.
13. ADVANTAGES
GPS works in all weather so you need not to worry of the climate as in other
navigating systems.
GPS costs you very low.
The most attractive feature of this system is its 100% coverage on the planet.
It also helps you to search the nearby restaurants ,hotels and gas stations and is very
useful for a new place.
GPS is extremely easy to navigate as it tells you to the direction for each
Turns you take to reach to your destination.
14. Disadvantages
GPS satellites are weak ,so it doesn’t work as well indoor, underwater etc.
The highest accuracy requires line-of-sight from the receiver to the satellite,
This is why GPS doesn’t work very well in an urban environment.
If you are using GPS on a battery operated device, there may be a battery
Failure and you may need a external power supply which is not always possible.
Sometimes the GPS signals are not accurate due to some obstacles to the signals.
15. CONCLUSION
GPS is a network of satellites that continuously transmit coded information ,
Which makes it possible precisely identify locations on earth by measuring
distance from the satellites.
GPS although was developed for military purposes, but the number of civilian
users of GPS already well far exceeds than number of potential military.
As discussed in previous topic , its application fields vast and new applications will continue to be
created as the technology evolves.
