Question

What type of surveys use portable receiving antennas to gather data transmitted from satellites which are used to calculate the position of the object being located on the surface of the earth?

Answer 1

Answer: GNSS surveys

Explanation: The Global Navigation Satellite System, or GNSS for short, is a network of satellites that send signals that can be used to locate a receiver on the surface of the Earth. The Global Positioning System (GPS) is the most widely used GNSS system, but there are also GLONASS, Galileo, and BeiDou GNSS systems available.

There are several uses for GNSS surveys, including:

Boundary surveys, construction surveys, site surveys, topographic surveys, asset tracking, emergency response, and military applications are all examples of boundary surveys. GNSS surveys are an effective and relatively accurate method for locating an object on the surface of the Earth. The number of satellites in view, the quality of the receiver, and the setting in which the GNSS survey is being carried out all have an impact on the survey's accuracy. However, the accuracy of GNSS surveys is typically within a few centimeters.

The following are a few advantages of using GNSS surveys:

1. They can be utilized in a wide range of settings.
2. They are fairly simple to carry out.
3. The following are some of the issues that arise when using GNSS surveys:
4. They can be impacted by ecological factors like trees and structures.
5. They can be costly, particularly for surveys with high accuracy.

In general, GNSS surveys are useful for a wide range of tasks. They can be used in a variety of settings and are accurate and effective. However, high-accuracy surveys can be costly and subject to environmental influences.
