Profile: SITECH deals with trimble construction technology. We deal with grade control systems, site positioning systems, data services and construction services. The GCS900 grade control system is an earthmoving grade control system that puts design surfaces, grades and alignments inside the cab. It uses GPS, GPS & laser, or construction total station technology to position the blade or bucket in real time, thereby reducing material overages. The Trimble SPS882 GPS rover is designed to receive current and future satellite signals. This receiver supports GPS modernization through support of L2C code.
