GNSS Technology in the Construction Industry 

GNSS (Global Navigation Satellite System) works by satellites, that send out signals to receivers on Earth. GPS (Global Positioning System) is one component of the Global Navigation Satellite System and refers to the NAVSTAR Global Positioning System. GNSS is used in collaboration with GPS systems that carry atomic clocks for accurate time to show when satellites send signals, allowing the receivers to compute their position. Trimble GNSS receivers utilize the five current satellite constellations, GPS (US) QZSS (Japan), BEIDOU (China), GALILEO (EU), and GLONASS (Russia). Using all five constellations results in faster more accurate positioning, even in hostile environments.

Coordinate Systems 101

The basics of dealing with coordinate systems.

I conduct a lot of survey training for construction and mining clients. In every class I usually start off with a “Coordinate Systems 101” lesson. This is something most clients struggle with.  I find that there are a lot of people running GPS survey and machine control systems that may not have a basic understanding for how the coordinate systems relate to their jobsites. There are also experienced surveyors that tend to make these topics overly complex for most people trying to understand the basics. Here are some basic coordinate system rules for clarity.
