Frequently Asked Questions
Is the Topcon GT-1000 robotic?
The GT-1000 has ATR (Automatic Target Recognition) but not full servo robotic tracking — it doesn't continuously track a moving prism. It automatically aims at a stationary prism. Full robotic (continuous tracking) is available on the GT-1200 and GT series.
What is the accuracy of the Topcon GT-1000?
5 arc seconds angular, 3mm + 2ppm EDM — construction-grade accuracy for building layout, utility stakeout, and commercial site work.
What is the difference between GT-1000 and GT-1200?
GT-1000: 5 arc seconds, semi-robotic (ATR without continuous tracking). GT-1200: 1 arc second, fully robotic with continuous servo tracking. The GT-1200 enables true one-person layout; the GT-1000 requires a second person to hold the prism stationary while the instrument measures.
