One of the key features of the Sfaira ONE Plus Multi-Frequency GNSS is its highly lightweight and portable design. This device is designed with a diameter of 50 mm and a length of 149 mm, fitting easily into a pocket, handbag, or backpack.
This ergonomic design allows users to easily carry the device during field projects and perform data collection without fatigue.
The Sfaira ONE Plus Multi-Frequency GNSS is equipped with an advanced IMU module that enables surveying with a tilt of up to 60 degrees. Using this technology, users can perform data collection or stakeout operations without needing to keep the pole perfectly level.
This feature increases surveying speed and improves efficiency in environments where leveling the pole is difficult or time-consuming.
The Sfaira ONE Plus Multi-Frequency GNSS features an internal 4800 mAh battery, providing approximately 16 hours of continuous operation. This feature makes the device suitable for a full workday in field projects.
Furthermore, if needed, users can charge the device via the USB Type-C port using a power bank and continue working without interruption.
One of the practical features of the Sfaira ONE Plus Multi-Frequency GNSS is the ability to connect directly to a smartphone via Bluetooth. Users can easily manage surveying operations through their mobile phone or controller.
The Sfaira ONE Plus Multi-Frequency GNSS is compatible with SingularPad surveying software and also allows for the use of many common surveying and GIS software applications.
The Sfaira ONE Plus Multi-Frequency GNSS is designed for use in harsh environmental conditions. The device’s body features an IP65 rating, offering good resistance against dust and water splashes.
Furthermore, its resistance to drops from a height of 1.5 meters ensures that the Sfaira ONE Plus Multi-Frequency GNSS performs reliably in field projects and harsh working environments. The receiver is also capable of operating in extreme ambient temperatures.
SingularPad is an Android-based field surveying software that offers various surveying modes such as Static, RTK, and PPK. On the Sfaira ONE Plus Multi-Frequency GNSS, this software supports Base and Rover operating modes, provides diverse format support, features a simple and smooth user interface, and offers professional surveying methods to users.
