Rojone releases GPS L1/L2 repeater system

Supplier News

Rojone  has recently added a new mobile L1/L2 GPS repeater product to its already extensive family of commercial and military systems.

The ROJ-150 kit is specifically designed for troop carrying mobile platforms such as APCs (armoured personnel carriers).

When installed, the ROJ-150 system will re-transmit the GPS L1/L2 band signals within the enclosed vehicle to provide adequate coverage to maintain personal GPS receivers on equipment and man packs.

Connected between the vehicle’s existing external receive GPS antenna and any existing L1/L2 GPS receiver, the repeater uses a directional coupler technique to minimise any impact on the existing GPS system.

The ROJ-150 device is designed to be unconditionally stable and will not introduce any interference to the existing radios or GPS system on the same vehicle.
