Emesent GX1 Redefines Precision With RTK SLAM Technology
- by Stefan Gandhi
In the professional drone and surveying sector, accuracy, speed, and reliability shape every successful project. From infrastructure inspection and digital twins to asset management and construction planning, geospatial data must be captured quickly and delivered with confidence. The Emesent GX1 RTK SLAM Scanner addresses this demand by uniting advanced SLAM technology with integrated RTK and high resolution imaging in one unified system.
Developed by Emesent, the GX1 represents a major step forward for UK professionals who require survey grade results without compromising productivity. By eliminating drift, reducing setup complexity, and enhancing visual context, the GX1 supports modern workflows across engineering, construction, mining, utilities, and public infrastructure.
This article explores how the Emesent GX1 redefines terrestrial scanning and why it has become a trusted tool for precision driven projects.
Beyond Traditional Mapping Limitations
Surveyors and drone professionals have long faced a difficult choice. Fast mobile mapping systems deliver speed but often sacrifice accuracy. Traditional static scanners provide high precision but require long setup times and complex workflows.
The GX1 resolves this challenge by combining pioneering SLAM algorithms with integrated RTK and PPK positioning. Instead of choosing between efficiency and reliability, operators gain both in a single device.
This approach enables consistent results across large sites, confined spaces, and featureless environments where conventional SLAM systems struggle.
Accuracy Without Drift
In tunnels, warehouses, industrial plants, and open infrastructure corridors, standard SLAM systems can experience cumulative drift. Over time, this leads to warped point clouds and misaligned datasets that require extensive correction.
The Emesent GX1 addresses this issue through continuous fusion of LiDAR, inertial, and GNSS data.
Key accuracy benefits include:
- Global accuracy of 5 to 10 mm using GCPs or 15 mm via RTK and PPK
- Local accuracy of approximately 5 mm
- Precision down to 2 mm in controlled environments
- Sub-centimetre repeatability for highly consistent multi-pass surveys
By maintaining positional integrity from the start, the GX1 reduces post processing effort and improves confidence in deliverables.
Productivity Without Downtime
Time on site directly affects project cost and safety. Traditional tripod scanning and multi sensor rigs increase labour requirements and expose teams to hazardous environments for longer periods.
The GX1 operates at walking speed, enabling rapid site digitalisation with minimal disruption. Its handheld, backpack, and vehicle mounted configurations allow operators to adapt quickly to different environments.
Benefits for productivity include:
- Reduced site time by up to 80 percent
- Faster mobilisation and demobilisation
- Lower staffing requirements
- Improved safety through shorter exposure
For UK operators managing rail corridors, industrial facilities, and construction sites, this efficiency translates into measurable operational savings.
Clarity Without Gaps
Point clouds without strong visual context limit their value for inspection, reporting, and stakeholder engagement. Manual camera integration often introduces alignment issues and workflow delays.
The GX1 features a quad camera array with four 20 megapixel sensors built directly into the scanner body. This system captures near spherical coverage at high frame rates.
Key visual capabilities include:
- 360 degree horizontal and 284 degree vertical coverage
- Automatic colourisation of point clouds
- Integrated 360 degree panoramas
- High quality imagery for BIM and CAD environments
By embedding visual data into E57 files, teams gain immediate access to rich, interpretable datasets without additional processing steps.
Versatility Without Complexity
Survey projects rarely follow a single format. One day may involve indoor plant rooms, the next may require roadside scanning or warehouse documentation. Managing multiple devices and external sensors creates unnecessary risk and downtime.
The GX1 solves this through a unified hardware ecosystem with IP65 protection and zero external dependencies.
Deployment options include:
Backpack Mode
Balanced for long duration walking surveys with adjustable height and centre of gravity.
Handheld Harness
Optimised for confined indoor spaces requiring maximum manoeuvrability.
Survey Pole
Compatible with standard 5 eighth inch threads for overhead and ground level coverage.
Vehicle Mount
Designed for large area capture without additional electronics.
This flexibility supports consistent workflows across varied project types.
Integrated Hardware & Performance
The Emesent GX1 combines multiple advanced systems into a compact rugged platform.
Core specifications include:
- LiDAR performance of 1.92 million points per second
- Effective range up to 300 metres
- Internal 2TB SSD providing approximately 40 hours of storage
- IP65 rated enclosure for demanding environments
- Quad camera vision system with 4 x 20MP sensors
These features enable high density scanning in challenging weather, dust, and vibration conditions commonly found on UK industrial sites.
End To End Workflow Efficiency
Modern surveying requires more than data capture. Efficient processing, visualisation, and sharing determine project success.
The GX1 integrates seamlessly with Emesent’s software ecosystem.
Field Operations with Commander
Operators configure RTK, SIM connectivity, and camera settings while monitoring live feeds during scans.
Processing with Aura
Aura automates colourisation, image extraction, and georeferencing. High resolution imagery is embedded directly into deliverables for immediate use.
Data Distribution
Processed files export easily into industry standard platforms and cloud environments, supporting collaboration across engineering and design teams.
Unlimited on premise processing with no per scan fees protects project margins and simplifies budgeting.
Flexible Geo-Referencing For Demanding Projects
High stakes surveying demands reliable positioning in all environments. Urban canyons, remote sites, and indoor facilities often disrupt GNSS reception.
The GX1 includes a premium 448 channel RTK receiver with full PPK support.
This enables:
- Real time positioning for live monitoring
- Post processed corrections for challenging locations
- Consistent accuracy without external base stations
- Reduced dependency on traditional survey infrastructure
With this flexibility, operators maintain control over accuracy standards across every deployment.
Training & Usability For All Skill Levels
Technology adoption succeeds when systems are accessible. The GX1 is designed to support both junior surveyors and experienced specialists.
The intuitive interface, automated workflows, and real time monitoring tools reduce training time and minimise operational errors.
Organisations benefit from:
- Faster onboarding of new staff
- Reduced reliance on specialist operators
- Consistent output quality
- Improved project scalability
This balance of simplicity and power supports long term workforce development.
Future-Focused Software Development
Emesent continues to expand the GX1 platform through ongoing software updates.
Planned enhancements include:
- Improved SLAM repeatability and drift resistance
- Advanced mapping modes in Commander
- Automated image masking in Aura
- Enhanced PPK geo-referencing tools
