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.

GNSS and Adding an IMU to your Survey Rover

Two things have happened recently that will dramatically change the way your GPS rover works.

First, there are completely new GNSS capabilities from new satellites, new GPS systems, and new types of radio signals coming from space. Second, Inertial Measurement Unit (IMU) was added to the Trimble SPS survey Rover.
