The Trimble SPSx30-TS is a specialized total station-based machine control system engineered for contractors requiring ultra-precise automated grading and excavation in environments where satellite-based GPS proves unreliable or inadequate. Using total station laser technology paired with a Trimble SPS930 base station, the SPSx30-TS delivers 1-inch accuracy guidance to laser-equipped dozers, graders, scrapers, and excavators—enabling precision earthwork in tunnels, dense urban cores, under bridge structures, and other GPS-challenged locations where conventional machine control fails.
Total station-based machine control offers fundamental advantages over GNSS-only systems in challenging environments. Line-of-sight laser measurements work underground and in enclosed structures where satellite signals cannot penetrate. Coverage extends to site boundaries and adjacent properties without requiring extensive RTK base station networks. For contractors managing underground construction, parking structures, or urban infill projects, total station machine control transforms previously unmeasurable work into controlled, documented operations.
The SPSx30-TS combines a fixed total station tracking transmitter with mobile receiver units installed on heavy equipment, creating an automated positioning system that guides operators to designed grades in real-time. The laser tracker maintains continuous line-of-sight to reflective prisms on machine-mounted receivers, streaming position updates that display on in-cab monitors. Operators see design grades, actual machine position, and required adjustments simultaneously, enabling precise blade or bucket control without manual surveyor guidance.
GPS backup capability ensures your machine control system functions even if line-of-sight conditions temporarily degrade. The hybrid positioning approach means you're not dependent on clear skies or extensive RTK infrastructure—a critical advantage for contractors with diverse project types and challenging site conditions.
Remote machine control features enable authorized personnel to guide equipment from safe vantage points, reducing exposure risk on hazardous sites. Integration with Trimble SCS900 site controller software provides design file management, volume tracking, and documentation capabilities that transform laser-guided work into comprehensive project records.
