Use LaserGIS® to Achieve Centimeter Accuracy in GNSS Impaired Environments

by T Nyland 05/03/19

Technology has transformed our way of communicating and performing our work-based tasks that help us maximize our output, complete jobs quicker, and most importantly, increase our safety in the field.

The New World of Tech is gaining momentum, and while we haven’t conquered it by any means, the past decades have provided us with substantial milestones that are helping us pave the way to an even more connected future. GNSS, the Global Navigation Satellite System, is helping us shape this future.

LaserGIS^® Workflows Expand Accurate GNSS Mapping Capabilities

GNSS Mapping in the Modern World

Satellites are steadily multiplying and building a technological atmosphere providing humans with faster connection speeds and modernizing the Earth into an autonomous civilization. GNSS is becoming the world’s GPS: providing us with coordinates for whatever we may need. 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 provides autonomous geo-spatial positioning with global coverage to help us discover, build, and implement. 

Users who integrate GNSS receivers into their workflow have their position triangulated by grabbing signals from at least four GNSS satellite signals. Multiple satellite navigation systems increase a user’s accuracy as well. Discovering, building, and implementing, however, can be tricky when you happen to arrive in a GNSS impaired environment. 

A GNSS impaired environment happens due to the obstruction of the signal from buildings, terrains, or anything that causes the signal to be blocked. In addition, a GNSS satellite signal can be compared to a 50-watt lightbulb, making it an already weak signal to begin with.

The need for real-time, high-accuracy GNSS positioning is growing. Regulatory requirements on spatial data accuracy is increasing. Collecting highly accurate horizontal and vertical data is achievable in some areas, but how do we reach centimeter accuracy in GNSS impaired environments? 

The Power of Three

LaserGIS is our term for using TruPulse laser rangefinders as an integrated tool within workflows that allow users to assign coordinate and characteristic data to assets without physically occupying their location(s).

You can achieve centimeter accuracy in GNSS impaired environments on assets located in alleyways, under trees, and even in the middle of a busy street by uniting hardware and software solutions from industry leaders:
