The R750 is not only a direct replacement for the SPS85x series of receivers, but also comes with useful upgrades making it a versatile tool. As typical with a new product, out with the old; the SPS855 has been discontinued and is no longer available. The good news is the R750 uses the same antennas and data cables besides offering many new enhancements.
Several methods are available for construction surveying, from photogrammetry to traditional surveying to LiDAR, the latter of which has been increasing in popularity in recent years. Invented in the 1960s, LiDAR has quickly become a prominent technology in many industries, including construction, city planning and scientific research. But what is LiDAR, and how can you use it on your construction site? Read on to find out.

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.

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.
