GNSS signal splitter

A GNSS splitter connects an external antenna to two GPS receivers or repeaters simultaneously.

Optimised to pass signals within the GNSS frequency range.

Rugged construction ensures performance on land, sea or air.

There are two ordering options, depending on the functionality required regarding DC power supply/.

 

Option 1 – BT2DGPS

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.

DC voltage from the receiver on the primary port passes through to the antenna (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 both provide a DC voltage to power the splitter and the external antenna.

Receivers on both primary and secondary ports can power the antenna – but only one of them will.

Voltages from both receivers are monitored by internal circuitry – the highest voltage wins and is passed through to the antenna.

If the same voltage is supplied to both ports, the splitter will randomly select one of them to be passed to the antenna.

The antenna continues to receive power even if one of the receivers is not functional.

 

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