The S980 / S6II is a calibration-free GNSS receiver for measuring tilt. It operates using specially developed “RTK fusion” technology, which is a tilt measurement technology for angles between 0 and 60 degrees. The surveying process is accurate to the centimetre and takes just three seconds. The precision manufacturing of the device and its innovative mechanical build optimise the electromagnetic shielding of the product, making it particularly reliable. The S980 / S6II has a compact design and is equipped with multiple interfaces in order to ensure compatibility with other RTK devices.
