What is a GPS and how it is used?
GPS means Global Positioning System. the world wide navigational and surveying facility system based on the reciption of an array of signals from the arbitary satellites
Does Trinidad have a gps system?
Yes, Trinidad and Tobago have a GPS system, which is operated by the government in collaboration with various private organizations. The GPS system in Trinidad is used for various purposes, including navigation, surveying, and tracking.
How can GPS be used in communication?
Global Positioning System is a system for determining your position on the surface of the Earth. As such, other that for reporting your position, it has little use in communication. GPS is of almost universal use in land surveying, but again, that is not comms.

What is satellite surveying?
Satellite surveying is a form of land survey that uses location information provided by the GPS satellite system to track the location of each reference point.
What is the definition for GPS?
GPS stands for Global Positioning System and is a satellite-based navigation system that provides location and time information to users anywhere on or near the Earth. It relies on a network of satellites that transmit signals to GPS receivers, allowing users to determine their precise location. GPS is commonly used in various applications such as navigation, tracking, mapping, and surveying.
Which statements describe Global Positioning Systems?
GPS is a satellite-based navigation system that provides location and time information anywhere on Earth. GPS receivers use signals from at least four satellites to calculate the device's precise location. GPS is commonly used in applications such as mapping, surveying, disaster relief, and personal navigation.

How can a gps be used by?
A GPS (Global Positioning System) can be used by individuals for navigation purposes, helping them determine their location and find the best routes to their destination. It can also be used by organizations for tracking vehicles or assets, improving logistics and efficiency. Additionally, GPS technology is utilized in various industries such as agriculture, aviation, and outdoor activities for mapping, surveying, and safety purposes.
Why is GPS not used for land surveying anymore?
GPS is still widely used in land surveying but has evolved with technological advancements. Traditional standalone GPS might not always provide the high precision required for detailed surveys. Techniques like Real-Time Kinematic (RTK) GPS and Differential GPS (DGPS) offer the necessary accuracy. Modern surveying often integrates GPS with other technologies such as drones, LiDAR, and GIS, enhancing data collection and analysis. In dense urban areas or heavily forested regions, GPS signals can be obstructed, so surveyors use additional methods to ensure accuracy. The development of sophisticated equipment combining GPS with other sensors provides more comprehensive data. Some projects also have specific regulatory or practical requirements dictating the use of various technologies. While standalone GPS might not suffice for all needs, it remains essential when used with advanced tools and techniques.
What is mean by RTK GPS?
RTK stands for Real Time Kinematic (GPS). Briefly, it is a way of using two (or more) earth based GPS units to solve the inherent ambiguities in the GPS system, to arrive at a submeter (usually 5cm or less) position solution.
There are men around the roads of belfast these days carrying poles with glass domed devices on top They are clearly measuring something - but what?
Those devices are most likely RTK GPS Surveying equipment.These are modern versions of Surveyor's Transits and are using GPS satellites for surveying. These are extensively used in civil engineering, road construction and measurement. The dome at the top captures triangulation data from GPS satellites.
