Integrated Rack Mount Splitter

The IRMS splitter family amplifies and splits the GPS/GNSS signal from a single or dual GPS receive antenna while granting up to 32 GPS/GNSS receivers signal access at any time. The most common use being the input from an active GPS roof antenna or GPS simulator is split to thirty-two receiving GPS units or timing boards.

Rack mounts are commonly used by cellular, timing, and test labs utilizing GPS. The IRMS is available with more options than other competitive products.

A GNSS receiver within the IRMS family of splitters monitor the antenna signal strength. There is also internal monitoring of the antenna current draw.

The dual power supply option allows two internal power supply units to share the load. If one unit is not available, the other will seamlessly take over without any loss of power. The power supply LED fault indicator is clearly visible on the front panel, and can also transmit using the contacts made available on the back panel.
