The primary differences are in two areas - technology and usage. GPS surveying uses similar technology to nearly any other GPS application - however, how surveyors use GPS differs significantly.

Leading Expertise For Your 3D Modeling Needs In combination with other surveying equipment, like the Total Station, GPS technology provides valuable information for surveyors to help develop plans and models for client projects. Surveying was one of the first commercial adaptations for GPS for its ability to obtain latitudes and longitudes without the need for measuring distances and angles between points. It’s particularly useful for the surveying industry. While most people are familiar with GPS and have used it to some degree on their smartphones or car navigation systems, GPS is a powerful tool for commercial applications. No matter the weather conditions or time, GPS can triangulate the signal and provide a location. If the receiver is moving, continuous data collection can be used to calculate the changing position of the receiver over time, which can be used to calculate speed. The information collected from these satellites then calculates the latitude, longitude and height of the receiver. When a receiver requests data to calculate its location, four or more GPS satellites will communicate with the receiver, sending the position of the satellite, the time the data was transmitted and the distance between the satellite and the receiver. GPS uses a network of satellites, which communicate with receivers on the ground. Since then, it has expanded its use to consumer and commercial applications. GPS was first developed for military use starting in the 1970s and became fully operational in 1993. In short, GPS, or the global positioning system, is a satellite-based navigation system. To understand the GPS surveying process, you need to understand what GPS is. Decoding GPS Surveying: An Introductory Overview Despite the widespread usage of GPS technology in surveying, however, it’s not a topic many know about - that’s why we’re here to explain the GPS surveying basics. Today, surveying professionals rely on GPS to provide accurate and reliable data for clients across a wide range of industries and applications. In fact, the surveying industry was one of the first to utilize GPS technology, recognizing the potential benefits of the technology. Surveying has changed substantially over the years - what used to take months of observation, measurement and geometrical calculations now takes a few hours or days thanks to the introduction of GPS technology.
