A Complete Guide to High-Accuracy Measurements In Disconnected GNSS Environments

We’ve all experienced a frustrating lack of signal service when working in the middle of a city or under dense canopies, making us wonder how in our tech-driven world. The past few decades we’ve seen technological innovation skyrocket, giving us our most connected and advanced world modifying how we live, work, and communicate with one another. We haven’t conquered the technological sphere by any means, and the past few decades of innovation have provided us with a vision of what we can become. Maximizing outputs, completing tasks quicker, and increased safety are some of the main driving factors that are provoking the geospatial industries to advance farther. For surveying professionals, it was the demand for engineered devices that let users achieve centimeter-accuracy in Global Navigation Satellite System (GNSS) impaired environments: driving top industry experts to develop a sophisticated solution.

GNSS is one of four satellite positioning systems. You likely have heard of the Global Positioning System (GPS), but there are some satellite systems that may not be so familiar, like BeiDou Navigation Satellite System (BDS) and Galileo. Each one of these acronyms embodies a specific group of artificial satellites that send position and timing data from their orbit by firing two carrier waves (L1 and L2) of information between Earth and satellite. The user’s antenna receives the signal and the processing unit makes sense of it. In addition to these four satellite systems there are a collection of satellite constellations orbiting around the Earth’s surface continuously transmitting signals. Collectively working together, these satellites are positioning us to become an autonomous geospatial world, with GNSS positioning itself to be the world’s new GPS. Whether we are looking to construct new buildings, provide more telecommunications for our 5G future, or to simply find where we are going when we get lost, GNSS is paving the way for us to get there.
