The secret of useability

The Satcube Ku provides high performance satellite broadband with speeds of up to 20 mbps. The terminal builds upon a unique pointing system which allows the user to point the antenna with an accuracy of within 0.2 degrees. This is achieved with high-performance navigation sensors and smart software integration. The refined user interface on the display guides the user to optimal performance everytime, everywhere. 

 

The Satcube navigation system utilises GPS, Global Positioning System, to accurately provide location. The angular position of the antenna is determined by the IMU, Inertial Measurement Unit, which includes accelerometer, MEMS gyroscope and Power Density sensors.

The accelerometer is used as an inclinometer for the polarization, tilt angle, and the elevation axis. The MEMS gyro is physically aligned to the azimuth axis to report any relative movement of the terminal in azimuth. The terminal locates the satellite carriers by measurements provided by the Power Density Sensors. A wideband and a narrowband sensor is in use to create what is on the Satcube Ku display is shown as RQ, Receive Quality. Azimuth pointing is determined through the magnetic compass included. As magnetic compasses are prone to magnetic variations and interference the user interface plays a big part in guiding the user to the satellite.

 

The Satcube Terminal is unique in its usability which is supported by the embedded system. The system not only guides the user, but should the terminal be blocked or misdirected the transmission is interrupted automatically and assumes a waiting state until the terminal is properly aligned.

The Satcube Ku User Interface

The system provides the coordinates to the selected satellite to where the user then adjusts the elevation and polarization. The user then proceeds to align the terminal in azimuth which is guided by arrows. The correct position is reached when the double arrows appear and the azimuth gauge is filled up, as shown in the picture above. The azimuth gauge is filled according to the signal strength, the RQ-value. Once pointed the transmission can be started and connection will be established.

 

The pointing system provides sufficient measurement accuracy to be able to point the antenna against correct satellite orbit position within 0.2 deg (RMS) accuracy in all axes.
