GPS Reflects The Technological Advances On This Earth. What Do You Know?

Explanation
The correct answer is "Global Positioning System." GPS is an acronym that stands for Global Positioning System. It is a satellite-based navigation system that provides location and time information anywhere on Earth. It uses a network of satellites to accurately determine the position of a GPS receiver. This technology is widely used in various applications, such as navigation devices, smartphones, and vehicle tracking systems.

Explanation
The correct answer is USA because the question asks about the country that owns the system, and the USA is known for having ownership of various systems and technologies.

Explanation
In 1978, GPS (Global Positioning System) was first launched. GPS is a satellite-based navigation system that provides location and time information anywhere on Earth. It was developed by the United States Department of Defense and initially used for military purposes. Over time, GPS technology has become widely used in various civilian applications, including navigation, mapping, and tracking.

Explanation
GPS (Global Positioning System) entered into full operation in the year 1995. This means that it was fully functional and available for public use starting from that year. Prior to 1995, GPS was still being developed and tested, and it was not until 1995 that it became fully operational and accessible to the general public.

Explanation
GPS satellites typically have a mission lifespan of 3-4 years. This is because the satellites are constantly exposed to harsh conditions in space, such as radiation and extreme temperatures, which can degrade their performance over time. Additionally, advancements in technology and the need for updated satellite systems also contribute to the relatively short lifespan of GPS satellites.

Explanation
Analyzing other satellites is not a use of GPS. GPS, or Global Positioning System, is primarily used for navigation and positioning purposes. It provides accurate location information and helps in various activities such as mapping forests, assisting farmers in harvesting fields, and navigating airplanes on the ground or in the air. However, analyzing other satellites is not a function typically associated with GPS.

Explanation
GPS is a network that combines the operations of up to 30 satellites. These satellites are placed in orbit around the Earth and transmit signals that are received by GPS receivers on the ground. By receiving signals from multiple satellites, a GPS receiver can triangulate its position and provide accurate location information. Having access to a large number of satellites increases the accuracy and reliability of GPS positioning.

Explanation
GPS satellites orbit the earth at an altitude of approximately 20000km. This high altitude allows the satellites to have a wide coverage area and ensures that they can maintain a constant line of sight with GPS receivers on the ground. Additionally, the higher altitude helps to minimize the effects of atmospheric drag and allows the satellites to remain in orbit for longer periods of time without needing frequent adjustments.

Explanation
Trilateration is the process used by GPS receivers to pinpoint a target's location. It involves measuring the distance between the target and multiple known reference points, called satellites, and then using those distances to calculate the target's exact position. By intersecting the spheres created by these distances, the GPS receiver can determine the target's location accurately. Trilateration is a fundamental technique in GPS technology and allows for precise positioning and navigation.

Explanation
GPS tracking does not require internet because it relies on a network of satellites to determine the location of a device. The satellites send signals to the device, which uses the information to calculate its position. This means that GPS tracking can work even in areas without internet connectivity, such as remote locations or areas with poor network coverage. However, internet connection may be required to access additional features or services related to GPS tracking, such as map updates or real-time tracking.
