Rohde & Schwarz at sea. On the right wavelength

An example scenario at sea

A frigate on the Indian Ocean. Its mission: to protect international trade routes. Long before unidentified ships are visible from the bridge of the frigate, the onboard reconnaissance system detects several suspicious communications signals. Direction finding measurements show that two unidentified ships approached each other, remained next to each other for two hours, and then went on their separate ways. Could they be smugglers?

The captain uses the internal communications system to consult with the operations room, which receives all incoming data and generates the current common operational picture (COP). The commander decides to set course towards the source of the signals. A shipboard helicopter takes off for visual reconnaissance. Those involved in the operation maintain constant contact over secure encrypted radio links. Still and video images of the observed incident and the situation report are sent to fleet command via secure communications channels in anticipation of further instructions.

All-rounder for secure onboard communications

The robust, end-to-end encrypted communications solutions focus on software defined radios. They enable voice and data communications in the HF and VHF/UHF frequency ranges with multiple security levels over various ranges.

The hub of all onboard communications is the NAVICS® integrated communications system. It interconnects the onboard voice terminals and all other subsystems for internal and external communications via a uniform IP network. The system also manages all radio lines and frequencies, prioritizes message exchange and controls the connected telecommunication devices. Its multilevel security architecture enables secure, trustworthy and tap-proof communications.

To enable free onboard movement as much as possible and increase flexibility, NAVICS® offers a Wi-Fi based communications system. In combination with a special application, this transforms smartphones into full-featured mobile voice terminals.

No more onboard crowding

Even on the largest platforms, space is a scarce resource. The numerous antennas required for communications, navigation and reconnaissance as well as weapons and radar warning systems mean that space can quickly become tight.

Integrated antenna systems from Rohde & Schwarz reduce the number of onboard antennas. They combine several high-performance transmit antennas with highly sensitive direction finding and detection elements on a single mast. Alternatively, the systems can be space-saving integrated components of multifunction masts. Omnidirectional capability and an optimized radiation pattern are indispensable, for example to ensure smooth communications with incoming aircraft.
