CHCNAV has introduced the TC100, a rugged field tablet designed as the dedicated controller for its ViLi i100 system. Positioned for surveying and construction environments, the device focuses on one of the most persistent field challenges: screen visibility under direct sunlight.
The company’s SunDefy display technology is central to that approach. In practical terms, it allows operators to work with CAD drawings, coordinate grids, and layout data without constantly adjusting viewing angles or searching for shade. That matters in real jobsite conditions where quick verification of points or linework often happens under full daylight exposure. Reducing that friction directly improves productivity during stakeout and inspection tasks.
High performance platform handles large CAD files up to 200 MB
Under the hood, the TC100 is built around a new generation processing platform aimed at handling heavier design data in the field. Support for CAD files up to 200 MB puts it in a category where it can realistically replace laptop based workflows for many use cases.
Performance gains are not just about opening files faster. Smooth panning, zooming, and editing of complex drawings is where field tablets typically struggle. In this case, CHCNAV is clearly targeting surveyors and construction crews who rely on real time interaction with detailed plans rather than static viewing. When workflows depend on frequent adjustments and on site decision making, responsiveness becomes critical rather than optional.
Rugged tablet design with IP67 protection and extended battery life
From a hardware standpoint, the TC100 follows the expected rugged device formula but with practical execution. IP67 protection ensures resistance to dust ingress and water exposure, which is essential for daily use across construction sites, infrastructure projects, and agricultural surveying environments.
Battery capacity is rated at 10000 mAh, with more than 8 hours of continuous operation claimed under typical field conditions. Combined with automatic backlight management, the system is clearly optimized for full day deployments without relying heavily on external power solutions.
This matters more than it may appear. In real operations, downtime caused by battery limitations or overheating displays can disrupt entire workflows, especially during time sensitive surveying windows.
Tight integration with ViLi i100 expands system level efficiency
The TC100 is not positioned as a standalone device. Its role as an exclusive controller for the ViLi i100 system suggests deeper integration at both software and hardware levels.
The ViLi i100 itself is designed as a visual positioning solution that combines GNSS with imaging capabilities for enhanced accuracy and usability in complex environments. Pairing it with a purpose built tablet allows CHCNAV to control the full user experience, from data capture to visualization and verification.
This system level approach is increasingly common across geospatial manufacturers. Instead of relying on generic Android devices, vendors are moving toward tightly integrated ecosystems that reduce compatibility issues and improve reliability in demanding field conditions.
Why this release matters for surveying and construction professionals
The TC100 is not trying to redefine the category. Instead, it addresses specific pain points that professionals encounter daily: poor screen visibility, slow handling of large CAD files, and limited battery endurance.
By focusing on those areas and integrating closely with the ViLi i100, CHCNAV is reinforcing its strategy of delivering complete workflow solutions rather than individual components. For contractors, surveyors, and engineering teams, that translates into fewer workarounds and more predictable performance on site.
