The system: incorporates direction-finding equipment to improve locating mariners in distress improves interoperability amongst federal, state, and local agencies enhances clarity of distress calls allows simultaneous channel monitoring upgrades playback and recording feature of distress calls reduces coverage gaps for coastal communications and along navigable rivers and waterways supports Digital Selective Calling for registered users provides portable towers for restoration of communications during emergencies or natural disasters
Operational Capabilities Improved VHF Coverage (>95%) Contractor Maintenance (A0 > 99.5%) DF (+/- 2 degrees) DSC Capability Improved Playback capability Increased simultaneous comms capability UHF Comms
Communications Capability Coverage Requirement Receive a 2 meter 1 watt transmission at 20nm Protected Communications Legacy: DES-CFB R21: DES-OFB with a future upgrade to AES Communication Standard: APCO P25 One Dedicated Channel 16 Guard One Digital Selective Calling (DSC) Ch. 70 Two VHF Radios 136 - 174 MHz (Marine & Federal Band) One UHF Radio 406-420 MHz (Federal Band/Not Air-to-Ground)
Direction Finding (DF) DF Requirement +/- 2 degrees Equipment Specification +/- 1.5 degrees in a reflection free environment Observed Accuracy Varies based on the local environment (terrain, buildings, etc). Capability Two channels: Ch16 & 2nd frequency including 121.5 & 243 MHz Maximum Range Based on tower height & vessel antenna height Radio Frequency (RF) Line of Sight (LOS) Atmospheric effects allow the system to receive signals beyond LOS Transmit Power of Target 121.5 / 243 MHz: 0.1 watt Ch16: 1 watt
