Why Choose the i85?

The CHCNAV i85 is a powerful 1408-channel GNSS receiver that provides consistent, centimetre-level accurate positioning even in challenging conditions. The device supports all major navigation satellite constellations, including GPS, Galileo, GLONASS, BeiDou, QZSS, and SBAS.

CHCNAV’s iStar 2.0 algorithm engine performs ionospheric interference rejection for robust signal tracking, even in areas with high solar activity. The algorithm delivers 96% fixed reliability, crucial for detail-oriented scanning, such as utility mapping and construction layouts.

Powerful connectivity ensures your data is safe, with Bluetooth, Wi-Fi, NFC, and an RTK radio modem (410-470 MHz, Rx/Tx) built in. Those with less experience using GNSS receivers may find the i85 more intuitive to use as opposed to other models, due to its user-friendly features:

AR visualisation: seamless integration with the dual cameras for enhanced navigation and stakeout efficiency.

Next-generation IMU: auto-levelling and delivers 3cm accuracy with a 60° tilt.

The CHCNAV i85 is built to perform in all environments.

The pocket-sized receiver weighs just 0.8 kg and is easily transported, without causing user fatigue.

It’s designed to endure harsh conditions –  created with a magnesium-alloy housing that can withstand a 2-meter pole drop and has an IP68 rating.

 The impressive 20 hours of battery (as an RTK rover) ensure the i85 will continue to deliver results when you need them.

The CHCNAV i85 GNSS receiver is a lightweight, pocket-sized device that delivers high-precision surveying in challenging and inaccessible environments. Equipped with dual cameras, Ultra-IMU, AR capabilities, and a laser module, the i85 is powerful yet accessible, even for less experienced surveyors. It can also be easily mounted on a wide range of survey tripods and poles.

Surveying uses:

The CHCNAV i85 is a powerful GNSS receiver, well-equipped to gather accurate results in challenging conditions.

Hazardous environments:

If you’re frequently surveying in trying conditions with inaccessible targets, the i85 outperforms its competitors in capturing inaccessible data points. The receiver hosts an 8MP high-definition camera with 6x magnification for accurate data point capture, even when they’re out of reach. This, coupled with the intelligent green-laser aiming system, significantly boosts aiming efficiency, with the laser alone increasing efficiency up to 50%.

Forestry Surveys:

In areas of dense foliage where GNSS signals are obstructed, the i85’s high-precision laser ensures accurate data is collected. The laser is resistant to ambient light levels up to 50,000 lux, so it remains visible even in bright outdoor conditions.

Utility Mapping:

The multi-constellation tracking by the i85, combined with its RTK technology, enables the receiver to produce centimetre-level accuracy, essential for locating utility lines and valves.

Construction Surveys:

Construction work requires highly accurate data down to the centimetre. As construction surveys are typically conducted at the beginning of a project, any inaccuracies can have serious ramifications further down the line.
