What are the benefits of using GPS services in surveying?
posted 29th August 2024
GPS surveys are used by architects, engineers, developers, and planners. At a touch of a button, we can collect data and geometrical calculations by using satellites that send signals to our receiver here on the ground. GPS surveys are an accurate and non invasive measuring solutions that we use regularly.
What Are GPS Surveys?
Global Positioning Systems (GPS) is satellite based navigation systems, enabling surveyors to collect accurate coordinates of latitudes and longitudes without measuring distances and angles between points
How They Work
Using GPS in surveying is much easier than you may think. The GPS uses a network of satellites to transmit data to our receiver. The receivers communicate with the satellites, gaining accurate longitude and latitude of the point on the ground.
As our receiver starts communicating with a satellite, four surrounding satellites also transmit data, measuring the precise location, time of the reading, and distance to the height of the receiver.
What are the Benefits of Using GPS Services In Surveying?
GPS services offer numerous surveying benefits. At MB Survey Solutions, we use GPS before the development of any construction project. The benefits of using GPS services in surveying includes:
- No matter what the weather conditions are, GPS can triangulate the signal and provide a precise location
- They provide accurate geographic measurements
- They are easily transported to various locations where we are carrying out our surveys
- They can be used on any site
How Do We Use GPS Services in Surveying?
There are three methods of GPS measurements that we may use:
Static GPS Baseline
We use this method for long range measurements and distances. It detects the accurate distance between two points. We use two receivers, each one placed at the end of the line where we want to measure. The two receivers collect the GPS data for up to twenty minutes. We then use a specialised computer software programme to calculate the distance between the two receivers.
Real Time Kinematic Observations
With this survey, we use one receiver, which is called the base station, and another known as the rover station. The rover station is moved to multiple positions throughout the measuring process. We use this method for gathering accurate data over smaller areas.
Continuously Operating Reference Stations
This is a unique data collection solution using a base station that is installed in a permanent location. This means localised measurements are sent to the base station. We use this for major construction projects that need as-built surveys over a long period of time.
MB Survey Solutions will be able to provide you with 2D and 3D surveys, based on your requirements.
How Do I Get a GPS Survey?
The first step to getting a GPS survey is to give the MB Survey Solutions a call today and arrange for us to complete the survey. Once we have collected the relevant data, we will guide you through the results, helping you develop a plan for your construction project. Our surveys provide you with a better understanding of the surrounding environment and infrastructure.
Conclusion
At MB Survey Solutions we can help you decide which GPS survey method is best for your upcoming project, expertly guiding you through the process, providing you with accurate measurements you can trust.
