you have used other Global Navigation Satellite Systems (GNSS) products before, CHC
recommends that you spend some time reading this manual to learn about the special
features of this product. If you are not familiar with GNSS, go to www.chcnav.com for an
interactive look at CHC and GNSS.
1.1 Safety Information
1.1.1 Warnings and Cautions
An absence of specific alerts does not mean that there are no safety risks involved.
A Warning or Caution information is intended to minimize the risk of personal injury and/or
damage to the equipment.
WARNING - A Warning alerts you to a potential misused or wrong setting of the
equipment.
CAUTION - A Caution alerts you to a possible risk of serious injury to your person and/or
damage to the equipment.
1.2 Regulations and Safety
The receivers contain a built-in wireless modem for signal communication through Bluetooth®
wireless technology or through external communication datalink. Regulations regarding the
use of the wireless modem vary greatly from country to country. In some countries, the unit
can be used without obtaining an end-user license. However, in some countries, the

2 Getting Started with i90
2.1 About the Receiver
The new CHCNAV i90 GNSS receiver offers integrated IMU-RTK technology to provide a robust
and accurate GNSS positioning in any circumstances. Unlike the standard MEMS based GNSS
receivers, the i90 GNSS IMU-RTK combines state-of-the-art GNSS RTK engine, calibration-free
professional IMU sensor and advanced GNSS tracking capabilities. Survey projects are
achieved with high productivity and reliability pushing the boundaries of conventional GNSS
RTK survey.
The LCD panel enables user to check satellite-tracking status, internal battery status, Wi-Fi
status, working mode, data logging status and basic receiver information. Bluetooth and Wi-Fi
technology provides cable-free communication between the receiver and controller.
The receiver can be used as the part of an RTK GNSS system with CHC LansStar7 software.
Moreover, user can download the GNSS data that recorded in the internal memory of receiver
to a computer.
The receiver can be used as the part of an RTK GNSS system with CHC LandStar 7 software.

+ vehicle battery.
In the office:
The Power Adapter is connecting with AC power of 100-240V, the output port of the Power
Adapter connects with the Power Port of the GPS to PC Data Cable.
In the field:
The external power cable is connecting with a vehicle battery, the output port of the external
power cable connects with the Power Port of the GPS to PC Data Cable.
WARNING – Use caution when connecting external power cable’s clip leads to a vehicle
battery. Do not allow any metal object to connect (short) the battery’s positive (+) terminal to
either the negative (-) terminal or the metal part of the vehicle battery. This could result in
high current, arcing, and high temperatures, exposing the user to possible injury.
