Overview

About the S9Ⅱ

Specifications

The materials of the S9 II have been further upgraded. Both the interior and exterior of the housing are crafted from high-strength magnesium alloy, achieving a true all-magnesium alloy design. While being lighter, sturdier, and more durable, the internal components feature completely wireless connections, making the entire instrument more stable and reliable.

The combination antenna has become standard on Stonex second-generation RTK products. The GNSS antenna, Bluetooth module, Wi-Fi communication module, and 4G module are highly integrated, simplifying design, reducing maintenance, and minimizing mutual crosstalk between components for greatly improved reliability. 360° omnidirectional zenith signal communication further improves the quality and range of signal transmission between devices. eSIM technology: Access CORS and network 1+N without inserting a physical SIM card.

Equipped with dual onboard smart lithium batteries featuring one-touch power level checking, fully interchangeable with data controller batteries. It supports automatic power switching and operates normally on a single battery. Hot-swapping is supported to ensure the S9 II operates continuously without interruption. The independent battery compartments provide multiple protections to prevent the battery covers from detaching during accidental drops.

The OEM board is considered the 'engine' of an RTK receiver. The S9 II is equipped with a world-leading OEM board engine, providing powerful processing capabilities. With 336 channels, it supports not only full constellations but also full systems—global navigation satellite systems, regional satellite navigation systems, wide area augmentation systems, and satellite-based augmentation systems. RTX service can be activated to meet standalone centimeter-level accuracy requirements for surveying operations. Multi-threading: The receiver can simultaneously record 8 threads of static data, each with independent settings for site name, sampling interval, recording duration, and data format.

Continuous R&D in tilt surveying technology has made it more mature and straightforward. The S9 II features a built-in high-sensitivity electronic bubble and applies a unique multi-point tilt measurement algorithm, delivering accurate data without calibration during surveying to further improve field efficiency.
