Errors in Global Positioning System

Errors in Global Positioning System

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,...

Field Application of Global Positioning System

Field Application of Global Positioning System

The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...

Reclosers and Fuses

Reclosers and Fuses

Automatic circuit reclosers enhance the protection of distribution circuits by interrupting and auto-reclosing an AC circuit according to a preset sequence. They effectively manage temporary faults on overhead distribution lines, often caused by tree limbs or wildlife, by briefly disrupting service to improve overall reliability. However, contact with reclosers or energized broken conductors on the ground can pose serious hazards.

Directional Relays

Directional Relays

Directional relays, essential for managing unidirectional fault currents, enhance the safety and efficiency of power systems. On power lines equipped with directional relays, faults downstream (to the right) of the current transformer typically cause the fault current to lag the bus voltage by approximately 90 degrees, known as the forward direction. In contrast, upstream (left-side) faults may result in the fault current leading the bus voltage by nearly 90 degrees, termed the reverse...

Radial System Protection

Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Area of Science:

Computer Science
Network Engineering
Traffic Management Systems

Background:

On-Road Sensor Networks (ORSNs) are crucial for traffic data collection, but vulnerable to failures.
Sensor failures can lead to large-scale communication disruptions in ORSNs.

Purpose of the Study:

To develop an effective fault-tolerance mechanism for ORSNs.
To ensure the continuous and reliable operation of ORSNs despite sensor failures.

Main Methods:

Proposed a fault-tolerance mechanism involving backup sensor deployment and redundant cluster head deployment.
Formulated backup sensor deployment as a two-objective optimization problem (cost vs. fault resumption).
Developed an Adaptive Detection and Resume (ADR) protocol for system communication recovery.

Main Results:

The proposed mechanism achieved an average 90% recovery rate.
Reduced the average number of failed sensors by up to 35.7%.

Conclusions:

The developed fault-tolerance mechanism significantly enhances ORSN reliability.
The approach effectively mitigates the impact of sensor failures on traffic data collection.
