Option 1 – BT2DGPS

GNSS splitter schematic

GPS signal from the antenna enters the splitter and is passed to both GPS receivers via primary and secondary ports.

The GPS receivers are both providing a DC voltage to power the splitter and the external antenna.

Primary port passes the DC voltage through (DC pass through).

Secondary port doesn’t pass the DC voltage through to the antenna (DC blocked).

 

 

Option 2 – BT2DGPS-2DC

GPS signal from the antenna enters the splitter and is passed to both GPS receivers.

The GPS receivers are both providing a DC voltage to power the splitter and the external antenna.

Port 1 passes the DC voltage through (DC pass through).

Port 2 doesn’t pass the DC voltage through to the antenna (DC blocked).

 

 

Also available from Forsberg Services is a comprehensive range of GPS amplifiers
