Trimble’s Real Time eXtended (RTX) correction service is a global GNSS correction source used to attain precise GNSS positioning. It operates the same as using a local base station, or Virtual Reference Station (VRS), to reduce the errors in GNSS positioning. Without corrections, a GNSS rover is only accurate to about 16 feet +/-. With corrections, GNSS rover positions are accurate to 0.02 to 0.06 feet.
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.
How to connect Bluetooth receivers is one of the most frequent support calls SITECH Southwest receives. The Bluetooth functionality in both Siteworks and SCS900 is managed by the Windows 10 operating system.
In this article we will take at look LiDAR for everyday use by testing a DJI L1 lens at a controlled testing site.
Simplifying your map maintenance process can relieve a lot of double work improving time, and frustration, and more importantly communication from the field to the office.
With the variables and nuances of constructing a corridor, collecting data in the most proficient and comprehensive way is crucial. In this article we go over components and stake features that are both required when using an SPS controller and helpful in executing your data.
2000 acres in one flight! That’s right, we did 2000 acres on one battery with five ground targets and around 30 check shots. The results amazed us!
As drone use has evolved, unmanned aircraft systems (or UAS) have become a sought-after tool for business and commercial applications.
In April 2019, Trimble introduced Tilt Compensation for the SPS986 receiver and Siteworks Controller software. Tilt Compensation is one of the biggest advancements in GNSS Site positioning. It improves accuracy and productivity in the construction workplace.
