Satellite Radio Comms Boost NSRI Rescue Efficiency in Trial

South Africa (23 October 2025) – The National Sea Rescue Institute (NSRI) is testing new satellite radios to solve a critical safety issue. For years, rescue crews have struggled with communication blackouts along remote coastlines. Traditional radios and cell networks frequently fail in areas like the Wild Coast and near Richards Bay. This leaves teams isolated during operations when contact is most vital.

Communication is Everything in a Rescue

Charl Maritz, NSRI’s Operations Manager, emphasized the importance of reliable contact. “Communication is everything in a rescue,” he explained. “If crews can’t talk to shore, they lose vital support and coordination. It slows down rescues and increases risk for everyone involved.” This gap in communication has been a persistent challenge for the organization.

Over the past six months, the NSRI has been trialing new satellite systems. These devices connect directly to satellites, bypassing the need for terrestrial towers. The initial results are promising. Crews report maintaining steady contact with their base in zones where signals previously dropped. This allows for real-time updates and more coordinated rescue efforts between the boats and shore command.

Improved Safety with Satellite Comms

As detailed in the complete version, there are several key factors to consider.

The benefits of reliable satellite comms extend beyond basic voice contact. “Reliable satellite comms improve safety,” says Charl Maritz. He notes that this technology makes rescues faster and more coordinated. It also gives crew members greater confidence, knowing they are never truly out of touch, even in the most isolated maritime environments.

While the trial has shown positive outcomes, cost remains a significant hurdle. Satellite radios are an expensive investment. The NSRI is currently prioritizing deployment to stations with the most urgent need. The potential long-term advantages, however, are substantial. Beyond emergency coordination, this technology could enable enhanced GPS tracking, real-time weather updates, and even live video feeds for improved situational awareness and training.

Looking ahead, the potential integration of services like Starlink could further revolutionize maritime rescue communications in South Africa. For now, the NSRI continues its trials. Crews already using the new satellite comms report feeling more supported and secure, a crucial step forward in their lifesaving mission.
