Overview

About the G970C Pro

The UniStrong G970C Pro is a fourth-generation GNSS receiver built upon the classic G970, achieving miniaturization and intelligence. Leveraging UniStrong's advanced resources, it is fully self-developed from chip to terminal with system-level optimization across all components. Equipped with the Tianqin chip, it supports satellite-based augmentation (PPP), while the new-generation calibration-free tilt survey algorithm delivers effortless, flexible measurement.

Specifications

The UniStrong G970C Pro is a miniaturized, intelligent fourth-generation GNSS receiver developed from the classic G970. Leveraging UniStrong's proprietary core technologies, it is fully independently developed from chipset to terminal, with system-level optimization across all components. Equipped with the Lyra chip, it supports satellite-based augmentation services (PPP), while its next-generation calibration-free tilt compensation algorithm delivers effortless and flexible surveying.

● Athena RTK Engine: The next-generation Athena RTK engine effectively enhances RTK initialization success rates and precision in harsh environments, supporting long-baseline RTK computation.

● aRTK Keep-Alive Technology: When traditional RTK data links are interrupted, aRTK technology maintains RTK-level precision for a sustained period of continuous operation.

● Global Positioning: Supports L-Band satellite signal tracking, achieving standalone centimeter-level positioning worldwide.

● Cellular Communication: Built-in high-speed cellular module supports full network connectivity, ensuring reliable operation without network compatibility concerns.
