The Stonex S55G is a high-performance RTK GNSS controller designed for precise surveying and professional field operations. It features a three-frequency GNSS board with 1408 tracking channels and supports all major satellite constellations: GPS, GLONASS, BEIDOU, GALILEO, QZSS, and IRNSS, ensuring robust and continuous positioning in every condition.
Powered by Android 12, the S55G delivers a fast, stable, and intuitive user interface fully compatible with Cube-a survey software. Its 5.5″ TFT display provides Full HD resolution (1920 × 1080 px) and 500 nits brightness, ensuring excellent visibility even in direct sunlight. The integrated QWERTY keyboard allows efficient data entry and comfortable control in the field.
The S55G operates in real time with RTK corrections, reaching centimeter-level accuracy (<1 cm), while simultaneously recording raw GNSS data for post-processing. For enhanced precision, it supports the external SA85 antenna and, when paired with the SR02 UHF radio, can receive base-station corrections directly via radio link.
An integrated red laser pointer helps accurately identify ground targets during stake-out or data acquisition and can be activated directly from the Cube-a interface. In situations without local RTK corrections, the S55G maintains decimetric accuracy by using Galileo HAS and BeiDou B2b PPP correction services.
The S55G provides a complete, multi-constellation, multi-frequency GNSS solution that combines portability, precision, and versatility, making it ideal for demanding professional surveying applications.
