The receiver features multiple connectivity options, including Bluetooth, Wi-Fi, UHF radio and 4G modem, ensuring reliable data flow to the controller. With an internal 10.200 mAh battery, the S990+ can operate for up to 9 hours and can be recharged via a USB Type-C connector. The IMU system supports tilted measurement (TILT) with quick initialization, providing accurate surveys even in challenging conditions. The color touch display and Web UI offer complete control of the receiver, while the 1PPS port ensures precise timing for multiple facilities and systems integration. The S990+ also offers an optional double-frequency UHF radio and 4G modem, making it suitable for use in different countries.
