Simrad RS100-B Black Box VHF And AIS with GPS500

The Simrad RS100-B Black Box VHF and AIS with GPS500 is a professional-grade marine communication and navigation system designed for vessels requiring redundant, network-independent radio and positioning capabilities. Built for maritime professionals, law enforcement marine units, and tactical operations teams, this integrated unit delivers real-time vessel traffic awareness, emergency distress functionality, and GPS positioning in a compact black box configuration. When communication infrastructure cannot be relied upon, the RS100-B provides autonomous VHF radio, dual-watch capability, and continuous AIS surveillance for maritime situational awareness.

This system combines International Maritime Organization–compliant VHF radio with Class B AIS receiver and integrated GPS500 positioning module, enabling simultaneous monitoring of emergency channels, working frequencies, and vessel position tracking without external network dependency. The black box design ensures durability in marine environments while maintaining compact form factor at 10 lbs, allowing flexible installation on vessels of varying sizes. VHF dual-watch allows operators to monitor Channel 16 and a working frequency simultaneously, critical for rescue operations and tactical maritime scenarios where missed emergency calls can be catastrophic. The GPS500 integration provides continuous position fixing for navigation, MOB (Man Overboard) functionality, and automated distress beacon transmission with precise coordinates.

Maritime law enforcement, Coast Guard auxiliary, naval security teams, and commercial vessel operators benefit most from this self-contained radio and navigation solution. The RS100-B functions as either a primary or backup communication system for tactical boarding operations, coastal patrol, and emergency response where independent radio capability is non-negotiable. Installation integrates with standard marine antenna systems and 12/24V DC power supplies common to tactical and commercial vessels. Network-independent operation means the unit remains fully functional during cellular outages, GPS spoofing scenarios, or contested communication environments—essential redundancy for maritime security operations.
