Full Description

The Topcon GT-700 Robotic Total Station is part of Topcon’s advanced GT Series - a next-generation line of compact robotic total stations engineered for efficient one-person operation on surveying, construction and civil engineering projects. With high-speed prism tracking and an easy-to-use digital interface, the GT-700 helps teams measure points quickly and accurately across a range of site conditions. Built around UltraSonic Direct Drive, brushless motors, the GT-700 moves smoothly and rapidly between targets, enhancing productivity when laying out points or capturing survey data. This technology, combined with robust prism lock and advanced servo control, supports dependable performance even on busy or complex sites. Engineered with real-world workflows in mind, the instrument integrates easily with Topcon MAGNET Field and other site software, allowing seamless data handling from site to office. Its compact, lightweight design makes it simple to transport and set up, while an IP65-rated rugged housing protects the unit from dust, moisture and everyday site impacts. The GT-700 is a practical choice for contractors, surveyors and site engineers who need efficient stakeout, control surveys, topographic data capture and construction layout. Supplied with essential accessories and compatible with Topcon field controllers, it supports streamlined workflows and reliable results for a wide range of professional applications. As Topcon's largest authorised distributor and service partner in the UK PQS Survey are positioned with the UK's biggest hire fleet and a dedicated technical team to provide you with the total station and service you require.

FAQs

What are the primary improvements in the GT-700 series compared to the older GT-600?

The GT-700 series features a significant increase in turning speed, reaching up to 200° per second. it also introduces an improved 10 Hz EDM update rate for smooth real-time tracking and an upgraded internal processor to handle larger data sets and complex 3D models within MAGNET software.

What is the benefit of the “Brushless” motors in the GT-700?

The GT-700 uses Intelligent Brushless Direct Current motors, which are thinner, lighter, and have no wearing parts. This results in ultra-silent movement, smoother prism tracking, and a lifespan up to four times longer than conventional motors, backed by a 5-year warranty.

Why is a 5″ instrument like the GT-705 so common in construction?

A 5″ instrument is the industry standard for general construction layout, providing a perfect balance of robotic speed and cost-effectiveness. Since its 2.5 mm deviation at 100 metres falls well within typical ±5 mm site tolerances, it avoids the unnecessary expense of over-specified accuracy.

Can I use the GT-700 with the HiPer VR / HiPer XR GNSS for a “Hybrid” setup?

Yes, the Hybrid Positioning package allows a HiPer series receiver to be mounted on top of the prism. The MAGNET software combines robotic measurements with GPS data, ensuring zero downtime by allowing you to switch between total station and GNSS tracking when line-of-sight is lost.

Where can I purchase a Topcon software licence?

PQS Survey Ltd is the UK’s largest independent Topcon distributor, offering 12-month or flexible software subscriptions for MAGNET Field and Topnet Live network RTK. We provide a one-stop shop for purchasing or renewing licences to keep your fleet connected to high-accuracy correction services.

How does “UltraTrac” technology prevent losing the prism?

UltraTrac uses advanced optical sensing and high-speed motor algorithms to distinguish your prism from other reflective objects like high-visibility vests. It is designed to ignore irrelevant reflections and re-acquire the prism instantly if the line-of-sight is temporarily broken by a vehicle or obstacle.

How does the RC-5A Remote help a one-man crew?

The RC-5A Remote sits on the prism pole and allows the operator to re-establish a lock with a single button press. It emits a 360-degree
