Reuters: Cyber threats prompt return of radio for ship navigation

LONDON (Reuters) – The risk of cyber attacks targeting ships’ satellite navigation is pushing nations to delve back through history and develop back-up systems with roots in World War Two radio technology.

Ships use GPS (Global Positioning System) and other similar devices that rely on sending and receiving satellite signals, which many experts say are vulnerable to jamming by hackers.

About 90 percent of world trade is transported by sea and the stakes are high in increasingly crowded shipping lanes. Unlike aircraft, ships lack a back-up navigation system and if their GPS ceases to function, they risk running aground or colliding with other vessels.

South Korea is developing an alternative system using an earth-based navigation technology known as eLoran, while the United States is planning to follow suit. Britain and Russia have also explored adopting versions of the technology, which works on radio signals.

As a reminder, the SDRplay RSP2pro is the version enclosed in a full-metal case for maximum RF shielding. Like the SDRplay RSP2 it has three software selectable antenna connections (long wire and two SMA), whereas the original SDRplay RSP1 has just the one SMA connector.

China’s campaign to eliminate pirate radio

Many thanks to SWLing Post contributor, Ken Hansen (N2VIP), who shares a link to the following news item on BGR India:

China to crackdown on unauthorised radio broadcasts

Reportedly, in a national campaign aided by more than 30,000 airwave monitors, in over past six months, more than 500 sets of equipment for making unauthorised radio broadcasts were seized in China.[…]

“The broadcast power of pirate radio stations can be 2,500 to 5,000 watts, which is several hundred of times that of commercial radio, and the signal can be received 300 km away,” the China Daily reported citing the department as saying. Pirate radios may also pose a threat to communication between aircraft pilots and ground controllers as their frequency band neighbours that of flight navigation signals and can create interference, the department said.
Under Chinese law, the unauthorised use of radio frequency bands can attract up to seven years in prison.
