GPS SYSTEM

GPS(GLOBAL POSITIONING SYSTEM):-

                                                           GPS or Global Positioning System is a satellite navigation system that furnishes location and time information in all climate conditions to the user. GPS is used for navigation in planes, ships, cars, and trucks also. The system gives critical abilities to military and civilian users around the globe. GPS provides continuous real-time, 3-dimensional positioning, navigation and timing worldwide.

                                              

System Description

GPS has three ‘segments’:
  1. The space segment now consists of 32 satellites, each in its own orbit about 11,000 nautical miles above the Earth.
  2. The user segment consists of receivers, which you can hold in your hand or mount in your car.
  3. The control segment consists of ground stations (five of them, located around the world) that make sure the satellites are working properly.

Application of GPS
GPS is extremely relevant today and used in numerous industries for preparing accurate surveys and maps, taking precise time measurements, tracking position or location, and navigating. Some examples of GPS applications include:
  • Emergency Response: When there is an emergency or natural disaster, first responders can use GPS for mapping, following and predicting weather, and keeping track of emergency personnel for safety. In the EU and Russia, the eCall regulation which comes into effect in 2018 relies on GLONASS technology and telematics to send data to emergency services in the case of a vehicle crash, reducing response time. Read more on the benefits of telematics.
  • Entertainment: GPS is being used for activities and games like Pokemon Go and Geocaching.
  • Health and Fitness: Smartwatches and wearable technology can be used to track your fitness activity (such as miles run,) and benchmark it against others that match your demographics.
  • Construction: From locating equipment, to measuring and improving asset allocation, GPS tracking allows companies to increase their return on assets.
  • Transportation: Logistics companies are implementing telematics systems to improve driver productivity and safety.
Other industries that use GPS include: agriculture, autonomous vehicles, sales and services, military, mobile communications, security, drones, and fishing.

The Future of GPS

Although GPS has performed extremely well and has generally exceeded expectations, it’s clear some significant improvements are needed. As we continue to investigate the system's needs and deficiencies over the past decade we are better able to determine what capabilities and features should be incorporated into a future GPS to satisfy both military and civil users.
3 Advantages of GPS:
  • GPS satellite-based navigation system is an important tool for military, civil and commercial, users
  • Vehicle tracking systems GPS-based navigation systems can provide us with turn by turn directions
  • Very high speed

multimeter

What is a digital multimeter? A  digital multimeter  is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries. Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. Fluke introduced its first digital multimeter in 1977. To better  understand  digital  multimeters,  it’s  helpful  to  become  clear  on  the  basics  of electricity.                       After  all,  digital multimeter  always  measure  some  aspect  of  electricity. In  the  case  of electricity,  that  force  might  be  a...

Annemometer

Annemometer is also known as wind speed meter. It is a measuring device.  It measure wind speed and it's direction. The term is derived from the Greek word  anemos , which means  wind , and is used to describe any wind speed instrument used in  meteorology . The first known description of an anemometer was given by  Leon Battista Alberti  in 1450. Connection For connection we need a wind speed sensor  & device for reading signal of sensor. First of we need a DC supply for activate sensor and device. Above picture it clear that wiring diagram. When a DC power supply connected with sensor and it blade run then in output we get signal. That signal connected in device. And device show result. Wind speed measure in m/s, kph, mph. Application Mostly wind speed meter used in industrial areas. And also it use in home.

Zoomlion Qy 50v Load chart free pdf download

A Chinese construction machinery manufacturer, having taken on the mission of contributing to our motherland through industry and through the great ambition of "broadening our vision by aiming high" for more than fifty years, we have taken one firm step after another on our way towards allowing "Made in China" to challenge the world standard. With steps restlessly marching forward and with a long, winding path covered by single individual strides for over half a century, each and every footprint made, burdened under heavy loads, demonstrates nothing but the strong demeanor and ambition that a climber shows while looking down upon everything from mountain peak. We have experienced innumerable glorious moments over the past fifty years, such as: showing our strength in the centennial Three Gorges Project, being highly praised for building the Antarctic Scientific Exploration Bases, challenging the extreme construction conditions on the Qinghai-Tibet Platea...
