Roger-GPS is a Finnish manufacturer for GNSS (GPS, GALILEO, GLONASS) solutions worldwide. ROGER GALILEO/GPS/GLONASS (GNSS-L1G1GA) repeater operates by receiving satellite signals with an antenna located outside the building and re-radiating the signals to the indoor area or covered space. Use of re-radiated signals indoors means that GALILEO/GPS/GLONASS receiver is tracking the current status and signal from the satellites. When a GALILEO/GPS/GLONASS receiver is moved from covered area to outdoors and vice versa, the receiver is instantly tracking the location instead of time consuming acquisition.
