CHC Navigation Introduces i83 IMU-RTK GNSS Receiver

CHC Navigation (CHCNAV) has announced the availability of the i83 GNSS receiver, a new and innovative addition to its premium GNSS receiver series for surveying, mapping and construction professionals. The i83 GNSS is powered by 1,408-channel multi-band GNSS, the latest iStar technology, and a calibration-free, high-end IMU sensor for faster and reliable field GNSS surveying.

“这i83接收器combines GNSS and IMU into one single receiver to provide optimal automatic pole tilt compensation that requires no calibration and is fully immune to magnetic interference. Operators just need to focus on their tasks and no longer need to level their pole vertically," said Rachel Wang, Product Manager of CHC Navigation's Surveying and Engineering Division. "In addition, we've designed a high-resolution colour display where users can clearly and intuitively get the GNSS receiver status to take full control of their survey operation."

Challenging GNSS Environments

The third-generation high-gain antenna with the latest advanced CHCNAV iStar algorithm improves GNSS satellite signal tracking efficiency by over 30%. The i83 GNSS receiver features 1,408 GNSS channels for unparalelled performance across GPS, Glonass, BeiDou, Galileo and QZSS constellations. The i83's onboard GNSS technology delivers centimetre-level positioning, maintains reliable fixed RTK accuracy and collects points faster than ever before, even in demanding conditions.

Compensate for Pole Tilt Automatically

I83 GNSS的内置IMU自动补偿了杆的倾斜度，比传统的GNSS RTK测量方法增加了30％的测量，工程和映射效率。在不到5秒的时间内，初始化了200 Hz惯性模块，以确保在高达30度的极点倾斜范围内进行测量级准确性。生产率大大提高，RTK可用性大大提高，并且无论您是工程师，现场工头还是测量师，可能会降低人为错误。

所有项目中的测量师的通用GNSS工具

Integrated Wi-Fi, Bluetooth and NFC modules provide seamless connection to field data controllers or tablets. Integrated 4G and UHF modems enable any GNSS survey mode, from RTK Networks NTRIP connections to UHF base-rover configurations. GNSS RTK corrections can be accessed or broadcasted continuously for accurate positioning in all circumstances.

由于I83 GNSS的超低电力SOC（芯片上的系统）电子设计和智能电源管理，用户无需在现场携带备用或外部电池。i83 GNSS可以作为GNSS RTK网络漫游器作为RTK基站运行长达18个小时或超过8小时。
