About Syslor
Syslor is a French company specializing in underground utility mapping. A pioneer in the field, Syslor has been developing simple, mobile, and reliable solutions since 2017 to support construction professionals throughout the entire jobsite lifecycle—from marking and staking to as-built documentation.
The Syslor ecosystem combines a GNSS receiver, mobile applications, and a collaborative web platform to help secure worksites, ensure reliable field data, and improve coordination between the field and the office, all while complying with regulatory requirements.
Syslor solutions are designed for public works professionals involved in underground utilities, utility networks (VRD), and earthworks. They are used in particular by surveyors, engineering consultancies, network operators, local authorities, public works companies, and industrial sites.

Data
Your data is stored on a secure, sovereign European cloud infrastructure.
It is redundantly stored and geo-replicated across multiple cloud storage locations to prevent any risk of data loss.
Data is organized by company and then by project. Each company has its own dedicated workspace that brings together users, equipment, and associated settings.
Projects then centralize data generated by the EasyField, EasyScan, EasyView, and EasyMap applications, which can be accessed and downloaded online 24/7.
Your data is stored for a period of 10 years. After this period, it is archived and can be accessed with a 72-hour notice.

Yes, using Syslor solutions requires a GNSS receiver.
The GNSS receiver developed by Syslor, is the reference solution.
Syslor applications are also compatible with certain third-party GNSS receivers, including the PYX receivers from Teria and the Reach RX and RS3 receivers from Emlid. Additional GNSS receivers will be added to this list over time.
Technology
GNSS RTK positioning relies on real-time corrected satellite signals to achieve centimeter-level accuracy.
A GNSS receiver captures signals from satellite constellations, while an RTK network provides correction data that compensates for errors and significantly improves positioning accuracy in the field.
Syslor is compatible with all existing RTK networks and has partnerships with Orphéon, SatInfo, Premium Positioning, and Teria.
For a more detailed explanation of GNSS and RTK principles, you can read our dedicated article:
Understanding the fundamentals of GNSS.
Syslor’s photogrammetry is based on video capture performed directly in the field using the EasyScan application on a smartphone or tablet. These videos are then processed to generate orthophotos and point clouds, which can be used within the Syslor platform for data visualization and vectorization.
To learn more about the topic, you can read our dedicated article:
Photogrammetry: principles, methods, and use cases.
Augmented reality applied to underground utilities consists of overlaying, in real time, the geolocation data of networks onto the live image of the actual terrain. It allows users to visualize the position of underground networks directly on site—without reopening trenches—using a smartphone or tablet. This helps facilitate marking and staking operations, secure interventions, reduce the risk of damage, and improve overall understanding of subsurface infrastructure.
Orthophotos and point clouds are generated through photogrammetry based on video captures performed with the EasyScan application. The user simply films the open trench using a smartphone or tablet.
The video is then processed to produce a georeferenced point cloud and an orthophoto, which are directly accessible within the Syslor environment for visualization, tracing, and data export.
Centimeter-level accuracy is ensured by the Proteus GNSS receiver.
Pricing & subscriptions
To learn more about our pricing, please contact us.
Syslor solutions are offered through a subscription-based model. The subscription provides unlimited use across all your worksites, with no additional fees and no token or credit system.

Syslor has chosen a subscription-based model to simplify the use of its solutions in the field. Pay-per-use pricing (tokens, credits, or per-action fees) often complicates cost tracking and can discourage tool adoption. With Syslor, teams can work freely and continuously without worrying about usage limits, while maintaining full budget control.

No, pricing does not depend on the number of users.
Syslor’s pricing model is based on the number of GNSS receivers used. One GNSS receiver corresponds to one subscription, to which as many users as needed can be assigned at no additional cost.
