Every coordinate your GNSS receiver calculates starts with a signal traveling from space at the speed of light. That signal carries precise timing information encoded
Your rover just lost RTK fix under a bridge overpass, and your layout points are 200 feet down the roadway. GNSS can’t see satellites through
Most surveyors and contractors assume RTK base stations are heavy, expensive boxes that need truck beds and permanent mounts. That assumption costs time and limits
GNSS stands for Global Navigation Satellite System, and it’s the umbrella term for all satellite positioning networks. GPS is just one piece of it, the
Most surveyors know GPS equipment has replaced chains and tape measures, but figuring out which GPS unit actually fits your work isn’t straightforward. The terminology
If you’ve been around surveying or construction long enough, you’ve probably heard the term surveying transit. The modern GNSS and RTK systems dominate most workflows
Walk onto any survey site, and you’ll see a mix of tools that haven’t changed much in decades alongside technology that didn’t exist five years
Before concrete is poured or utilities are installed, construction site surveying sets the entire project in motion. When done well, it saves time, money, and
Theodolites, total stations, and GNSS receivers each have their place in modern surveying. But knowing when to reach for which tool isn’t always obvious. Read
