Broad incumbents

• Furuno Electric:
• Marlink: Marlink is a global provider of maritime satellite communications and digital solutions, offering Inmarsat, VSAT, and GMDSS-related services. It is comparable to RSTA as both operate in maritime communications and connectivity services, though Marlink operates at vastly larger scale and across many more geographies.
• Iridium Communications: Iridium operates a global satellite constellation with maritime GMDSS recognition and offers Iridium Certus for ship communications. Comparable to RSTA because both serve the maritime satellite communications market, though Iridium operates upstream network infrastructure while RSTA is a downstream service bureau.
• Cobham SATCOM: Cobham SATCOM (which acquired Thrane & Thrane, RSTA's primary OEM partner) manufactures maritime satellite communications and GMDSS equipment. Comparable because RSTA distributes and integrates Cobham/Thrane & Thrane products, placing them in adjacent layers of the maritime communications value chain.
• Viasat (Inmarsat Maritime): Viasat owns the Inmarsat maritime satellite network that RSTA resells and accounts for. Comparable because both serve the same maritime communications value chain, though Viasat operates the upstream satellite infrastructure while RSTA provides the downstream service bureau and billing layer.

Direct peers

• Pole Star Global: Pole Star Global provides ship tracking, port call management, and maritime compliance SaaS including GMDSS-relevant services. Comparable to RSTA because both sell maritime tracking, communications oversight, and regulatory compliance services to fleet operators, though Pole Star is more software-oriented.
