Must be GPS , no other way to know otherwise , similar to the Snipe which says :
The Selfsat Snipe 3 'White Line' Twin Output fully automatic satellite antenna offers an inconspicuous installation due to its new completely white stylish design. The compact form factor of the SNIPE 3 antenna takes up very little space - ideal for mounting on the roof of a motorhome. Even the annoying alignment at a new location is eliminated. Thanks to the integrated GPS module and electronically controlled drive, the antenna automatically aligns itself at the touch of a button. You receive your usual desired program even when traveling, as long as the respective satellite is available. The SNIPE 3 automatically folds as soon as you turn off the receiver or start the vehicle.
