V700S-RTK
★ Flagship GNSS + SLAM Fusion Rover
Hi-Target · Model V700S
V700S SLAM RTK System.
Where GNSS ends, SLAM begins. A 1408-channel multi-constellation RTK rover with Laser Reverse Positioning — uninterrupted centimeter-level surveying from open sky to under bridges, indoors, and through dense canopy.
The V700S is Hi-Target's first true fusion rover. Outdoors, it delivers RTK precision through GPS, BDS, GLONASS, Galileo, QZSS, NavIC, and SBAS. The instant signal drops — beneath a bridge, inside a building, between high-rises — the integrated laser scanner and SLAM engine take over. Same device. Same coordinate frame. Zero workflow interruption.

When GNSS fails, SLAM takes over.
For two decades, GNSS surveyors have lost productivity the moment they walked under a bridge, into a stockyard, or beside a high-rise. Signals dropped. Survey paused. Crews placed temporary control points to bridge the gap.
The V700S ends that workflow. A high-precision RTK module delivers centimeter accuracy outdoors. The instant the GNSS signal degrades, Laser Reverse Positioning kicks in — using SLAM, an integrated IMU, and visual data fusion to maintain absolute coordinates. No control points. No re-registration. No re-walking previous routes. One unified BLH/NEZ output the whole way.

Key Features
Six engineering decisions
that make GNSS-denied
surveying productive.
Every feature exists to solve a real on-site bottleneck — not to fill a marketing slide.
FEATURE 01
Laser Reverse Positioning — surveying without signal.
Hi-Target's proprietary fusion technology that lets the V700S maintain centimeter-level positioning when GNSS satellites are blocked. Indoors, beneath bridges, between high-rises, under dense canopy — the laser scanner, IMU, and visual data fuse into a unified absolute coordinate solution. Same BLH/NEZ output throughout the survey, no datum shift, no manual re-registration.
Unified BLH / NEZ
Single coordinate frame across both positioning modes
FEATURE 02
Control-Free Scanning
No ground control points required. No need to return to previous locations. The fusion engine maintains absolute position from start to finish — dramatically faster on large or complex sites.
FEATURE 03
Built-in High-Precision IMU
No initialization walk required. Pole tilt up to 60° is auto-compensated with 8 mm + 0.3 mm/° accuracy. Capture points beside walls, fences, and corners without leveling.
FEATURE 04
3 Professional Dual HD Cameras
Visual stakeout, image measurement, and AR overlay. Working distance 2-15 m, better than 5 cm accuracy at 15 m, 2 cm AR stakeout precision.
FEATURE 05
AR Stakeout & Image Measurement
Design points overlay onto the live camera feed. A single photo captures multiple point coordinates with better than 5 cm accuracy at 15 m.
FEATURE 06
1408-Channel Multi-Constellation Receiver.
Tracks every operational GNSS constellation: GPS (L1C/A, L1C, L2P(Y), L2C, L5), BDS (B1I, B2I, B3I, B1C, B2a, B2b), GLONASS (L1, L2, L3), Galileo (E1, E5a, E5b, E6), QZSS (L1, L2, L5, L6), NavIC (L5), SBAS, plus B2b-PPP and Galileo E6-HAS precise-point services. In a Middle East sky with strong BDS visibility and parallel GPS / Galileo coverage, signal availability is unmatched.
7 constellations
All operational GNSS systems, plus PPP services
GNSS Engine
Every signal. Every constellation.
The V700S receiver is built for the next decade of GNSS, not the last one. As BDS-3 reaches full capability and Galileo HAS / BDS B2b PPP services mature, the V700S already tracks every frequency they broadcast — no firmware lock-out, no premium upgrade path.

Field Applications
Built for the projects
that defeat single-mode systems.
Wherever GNSS coverage flickers and SLAM-only systems lose absolute reference, the V700S keeps producing surveyable data.
Dense Urban Surveys
High-rise canyons that fragment multipath-free GNSS reception still survey cleanly when V700S falls back to laser positioning.
Indoor & Industrial Sites
Warehouses, factory floors, stockyards, and partially enclosed structures get the same coordinate frame as the outdoor approach work.
Road & Infrastructure
Continuous topographic data through tunnels, beneath gantries, and around bridge piers — no gaps to bridge with control surveying.
Underground Utilities
Manhole-to-manhole capture, service trench mapping, and partial underground entries while preserving absolute coordinates.
Railway Corridors
Through stations, beneath catenary, and across switching yards — V700S maintains the corridor's coordinate framework end-to-end.

Frequently Asked
Common questions about the V700S.
What is the V700S SLAM RTK System?
+
The V700S is Hi-Target's flagship hybrid GNSS-SLAM RTK rover. It combines a 1408-channel multi-constellation GNSS receiver, Laser Reverse Positioning, SLAM scanning, dual HD cameras, and an integrated IMU into one device. It delivers centimeter-level surveying both outdoors using RTK and in GNSS-denied environments using laser-based SLAM positioning — without requiring control points or returning to known locations.
What is Laser Reverse Positioning?
+
Laser Reverse Positioning is Hi-Target's proprietary fusion technology that lets the V700S seamlessly switch between RTK GNSS (outdoors) and laser-based SLAM positioning (in GNSS-denied areas like under bridges, eaves, dense canopy, or building interiors). Coordinates are output in a unified BLH/NEZ framework regardless of which positioning mode is active — the user never has to merge datasets or re-establish control.
What is the RTK accuracy of the V700S?
+
RTK accuracy is 8 mm + 1 ppm horizontal RMS and 15 mm + 1 ppm vertical RMS, with initialization time typically under 10 seconds and initialization reliability typically greater than 99.9%. High-precision static accuracy reaches 2.5 mm + 0.1 ppm horizontal and 3.5 mm + 0.4 ppm vertical for control survey work.
Can the V700S work without ground control points?
+
Yes. Control-free scanning is a core V700S feature. The fusion of RTK GNSS and SLAM means the system maintains its absolute coordinate framework throughout the survey — there is no need to revisit previous locations or place external control points to register data. This dramatically improves on-site efficiency on large or complex sites where traditional workflows would demand control surveying as a separate step.
What is the tilt survey accuracy of the V700S?
+
The V700S includes a built-in high-precision IMU module supporting tilt survey with additional horizontal uncertainty of 8 mm + 0.3 mm per degree of tilt. The pole no longer needs to be perfectly vertical to capture accurate coordinates, which significantly speeds up fieldwork around corners, walls, fences, and other obstacles. No initialization walk is required — measurement starts immediately.
What is AR stakeout on the V700S?
+
AR stakeout uses the V700S's three professional dual HD cameras to overlay stakeout points and design data directly onto a live camera feed. The operator sees exactly where to place stakes through the device screen — no more interpreting bearing and distance arrows. Working distance is 2 to 15 meters, with better than 2 cm stakeout accuracy and better than 5 cm image-measurement accuracy at 15 m range.
How long does the V700S battery last in the field?
+
The V700S delivers up to 10 hours of RTK rover operation (UHF or cellular) and up to 5 hours in SLAM scanning mode on a full charge. USB-C 45 W fast charging brings the battery from empty to full in approximately 2 hours, so a single spare battery comfortably covers a multi-day field campaign. The device also accepts standard portable power banks for emergency top-ups in the field.
What is the price of the V700S SLAM RTK in Dubai?
+
V700S pricing depends on configuration — system bundle, included tablet (Qpad 8-inch optional), accessory package, software bundle, and project quantity. Contact Sicher 3D at sales@sicher-3d.com or +971 50 108 0764 for authorized dealer pricing tailored to your project. Volume pricing is available for surveying companies, contractors, and government tenders across UAE and the wider GCC.
