CHCNAV iBase Integrated RTK GNSS Base Station
The CHCNAV iBase is an integrated GNSS RTK base station designed for control surveys, construction sites and other applications that require a reliable source of RTK corrections.
The iBase combines GNSS positioning, UHF radio and network connectivity in a single field-ready unit. Its DistLink technology is designed to reduce radio power consumption while improving rover signal sensitivity, helping extend the working range in challenging terrain.
With support for radio and network data transmission, the iBase can also adapt to different RTK workflows. The integrated design reduces the need for external batteries and cables, making the system easier to deploy in the field.
RTKSurvey.com supplies the CHCNAV iBase for professional surveying, construction and engineering applications.
Key Features
Integrated GNSS Base Station
The iBase combines the GNSS receiver, communication hardware and battery into one compact base station, simplifying field deployment for RTK surveying.
Up to 30 km RTK Coverage
CHCNAV DistLink technology improves rover radio sensitivity and enables coverage of up to 30 km under suitable conditions, providing a practical solution for larger survey areas.
Extended Base Station Operation
The iBase can operate for more than 13 hours as an RTK base with DistLink technology, helping reduce interruptions during long field projects.
Radio and Network Connectivity
The iBase supports UHF radio communication as well as cellular connectivity. Its Ultra Base mode is designed to combine radio and network transmission and automatically switch when the radio coverage limit is reached.
1408-Channel GNSS Tracking
The receiver uses a 1408-channel GNSS configuration and supports GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS and PPP services.
Rugged Field Design
With IP67 protection and 2 m drop resistance, the iBase is designed for outdoor surveying and construction environments.
