HTS-820 Robotic Total Station.
True one-person surveying — AI prism tracker, military-grade target lock, and Intelligent Imaging Station setup. The tool that lets you focus on engineering, not equipment.
Designed for surveyors who work alone but never compromise. The HTS-820 combines a 2″ angular accuracy rotary encoder, 5000m prism range, and a 5.5-inch Android touchscreen — all built into a rugged IP65 chassis that cuts field hours by 50%.

IP65 Rugged
Built for the Field
One surveyor. Zero compromises.
The HTS-820 was engineered around a simple idea: a single surveyor should never be slowed down by their instrument. Motorized servo drives spin the telescope at 180°/sec, the AI prism tracker locks onto your target like military fire-control, and the Intelligent Imaging Station eliminates the need to manually center or measure instrument height.
From rough terrain to dense construction sites, the HTS-820 delivers the kind of mechanical stability, optical precision, and software intelligence that turns days of fieldwork into hours — without the second crew member.

Key Features
Six engineering decisions
that change how you survey.
Every feature on the HTS-820 was added to solve a real fieldwork problem — not to fill a marketing brochure.
FEATURE 01
Hybrid Tracking — No more losing targets.
Our hybrid tracking system intelligently combines multiple data sources to maintain precision, even in challenging conditions. When the pole moves behind an obstacle and reappears, the system seamlessly reacquires the target — like military fire-control radar. Uninterrupted workflow, reliable results, zero re-shoots.
Auto-reacquire
Target lock recovery after obstruction
FEATURE 02
Intelligent Imaging Station Setup
Skip centering and instrument height measurement. The HTS-820 calculates them automatically using imaging — to 2mm accuracy. Setup time drops from minutes to seconds.
FEATURE 03
Smart Prism Search — 360° + AI
360° planar laser fan finds prisms 20–300m away. AI search uses camera + algorithm to lock targets within 20m. Two modes, zero wasted time.
FEATURE 04
Visual Stakeout
Skip squinting through the telescope. The live HD camera feed guides you to stake-out points visually — accessible for both novices and seasoned crews.
FEATURE 05
CAD Stakeout in One Click
The high-performance CAD engine delivers millisecond-level dynamic response. Select stakeout points and lines directly from the drawing — no exports, no conversions.
FEATURE 06
Android 9.0 + 5.5" HD Touchscreen.
A Qualcomm octa-core CPU at 1.8 GHz, 3 GB RAM, 32 GB storage, and a 5.5-inch 720×1440 touchscreen (≥500 cd/m² brightness) — outdoor-readable, gloved-finger operable, and powered by the Hi-Survey software suite with built-in support for road, bridge, and tunnel design workflows. Wireless connectivity over BT 4.2, 2.4 GHz dual-band Wi-Fi, and full LTE.
3GB + 32GB
RAM + ROM — runs Hi-Survey natively, no controller required
AI Prism Tracker
Target locked. Like military fire-control.
The HTS-820's AI prism tracker doesn't just follow your pole — it predicts where it's going, recovers when obstacles break line-of-sight, and reacquires faster than any optical search system on the market. Two intelligent search modes work together to keep your workflow uninterrupted.
360°
Super Search Mode — 20m to 300m
A planar laser sweeps in a fan pattern to find prisms across long distances, ideal for open construction sites and survey traverses.
AI
AI Search Mode — Up to 20m
The integrated camera and intelligent algorithms identify and lock onto prisms in close range — perfect for indoor work, congested sites, and tight building interiors.
↻
Hybrid Auto-Reacquire
When the pole disappears behind a column, tree, or moving vehicle, the system reacquires the target the instant it reappears — no manual re-lock.

Frequently Asked
Common questions about the HTS-820.
What makes the HTS-820 a true one-person robotic total station?
+
The HTS-820 combines motorized servo drives, an AI prism tracker, and remote pole-controller operation. A single surveyor can set up the instrument, walk to any point with the prism pole, and operate measurement, stakeout, and data capture wirelessly — no second person at the station required. The Intelligent Imaging Station setup further reduces the time spent at the instrument itself, since centering and instrument-height measurement happen automatically.
What is the angular accuracy of the HTS-820?
+
The standard HTS-820 offers 2 arc-second angular accuracy with a rotary absolute encoder. A 1″ precision version is available as an optional upgrade for projects requiring higher accuracy — geodetic surveys, deformation monitoring, or precision industrial alignment, for example.
How far can the HTS-820 measure with and without a prism?
+
With a single prism, the HTS-820 measures up to 5,000 m under general conditions and 6,000 m under good atmospheric conditions. With a reflective sheet, it reaches 500 m. In reflectorless mode (measuring against a Kodak white board at 90% reflectance), it measures up to 1,000 m with 3 mm + 2 ppm accuracy. Actual reflectorless range varies based on target reflectivity, surface texture, and atmospheric conditions.
Does the HTS-820 work with existing CAD and survey software?
+
Yes. The HTS-820 runs on Android 9.0 with the latest Hi-Survey software, which supports CAD stakeout with millisecond response, road / bridge / tunnel design modules, and standard exchange formats. Output integrates with AutoCAD, Civil 3D, Trimble Business Center, Bentley, and other industry-standard platforms. Data transfer is via Type-C USB, TF card, Wi-Fi, or Bluetooth.
How does the AI Prism Tracker compare to traditional auto-tracking?
+
Traditional auto-tracking systems lose targets the moment line-of-sight breaks. The HTS-820's AI Prism Tracker uses two complementary modes: a 360° super-search laser fan for 20–300 m distances, and an AI-camera search for under 20 m. When the pole is obstructed (by a column, vehicle, or tree) and reappears, the system auto-reacquires the target instantly — without manual intervention.
What is the warranty for the HTS-820 in UAE?
+
Sicher 3D provides a 1-year manufacturer warranty on the HTS-820 mainframe and 3-month warranty on battery and accessories. We also offer on-site training, calibration support, and after-sales service across the UAE, Saudi Arabia, Oman, and wider GCC. Extended warranty and service contracts are available on request.
Is the HTS-820 suitable for outdoor work in extreme temperatures?
+
Yes. The HTS-820 operates reliably from −30 °C to +50 °C and is rated IP65 against dust and water jets — well-suited for the harsh outdoor conditions of Middle East construction and surveying. The 5.5″ display offers ≥500 cd/m² brightness for direct-sunlight readability.
What is the price of the HTS-820 Robotic Total Station in Dubai?
+
HTS-820 pricing depends on configuration — 1″ vs 2″ accuracy, accessory bundle, software options, and project quantity. Contact Sicher 3D at sales@sicher-3d.com or +971 50 108 0764 for an authorized dealer quote tailored to your project scope. Volume pricing is available for survey companies, government tenders, and large construction projects.
