About the G669

Specifications

The G669 BeiDou High-Precision Handheld is equipped with a GNSS L1+L5 dual-frequency high-precision positioning module and proprietary RTK algorithms to achieve centimeter-level positioning accuracy. Featuring flagship hardware such as a 4-inch HD display, a quadrifilar helix antenna, a high-capacity battery, and a high-power speaker, it satisfies multi-dimensional high-precision industry applications including GIS data collection, smart push-to-talk (PTT) intercom, and personnel tracking, advancing high-precision BeiDou spatiotemporal information applications.

● Dual-Frequency High-Sensitivity GNSS Signal Reception

With a GNSS signal tracking sensitivity of up to -165 dBm, the G669 ensures reliable GNSS positioning even in challenging environments. The device supports all-constellation L1+L5 dual-frequency signal tracking across BeiDou, GPS, GLONASS, Galileo, and QZSS, delivering superior positioning accuracy.

● Proprietary RTK Algorithm for Centimeter-Level Accuracy: Powered by UniStrong's proprietary RTK algorithm, the G669 delivers instant fixed solutions when receiving ground-based differential correction signals. Tailored to GIS industry requirements, the algorithm is optimized to maintain smooth tracking trajectories even when a fixed solution cannot be reached, ensuring reliable fixes and drift-free float solutions to fulfill all-scenario field GIS requirements.

● Flagship Performance and Robust Hardware: Equipped with a quad-core 2.0 GHz CPU and 3 GB + 32 GB storage, the G669 delivers a 50% overall performance increase over its predecessor (G659). The upgraded hardware ensures smooth, efficient data processing to support demanding enterprise and industrial workflows.

● Smart Intercom for Instant Communication: Featuring a 3 W high-power speaker, dual AI noise-canceling microphones, and a dedicated PTT button, the G669 enables network-based smart intercom functionality. It fulfills the needs of high-precision personnel tracking and dispatch communication in dense environments such as airports, mines, factories, ports, and chemical parks. Professional accessories including desktop charging docks and intercom headsets support prolonged, high-intensity operations.
