About this file
This file contains a set of technical questions posed by the United States Coast Guard to potential vendors for the Nationwide Automatic Identification System (NAIS) Support Services in Alaska. The questions are designed to evaluate vendor capabilities across multiple critical dimensions of the proposed solution.
The questions address system architecture and redundancy, specifically requesting details on antenna placement within strict wind and ice-loading constraints, failure mitigation strategies to ensure VHF/DSC communications remain fully operational if the AIS subsystem fails, and power budget impacts from AIS transmission. Vendors are asked about automatic power prioritization during power generation degradation and the modularity of AIS transmit capabilities given the build-to-cost mandate. Coverage and performance inquiries include satellite coverage beyond 24-50nm with specific data on Alaska Area of Responsibility satellite coverage and latency metrics, VHF voice and data (DSC) send/receive ranges, and current service coverage areas. Environmental and operational resilience questions focus on remote diagnostic capabilities over low-bandwidth satellite backhaul, autonomous power solutions for off-grid remote sites, technician deployment lead times to isolated communities, local parts caching within Alaska to minimize Mean Time To Repair, hardware protection against icing and signal loss during severe weather, and propagation modeling that accounts for Earth Bulge effects and high-latitude signal loss. Additional questions address Aurora Borealis and solar flare mitigation, interoperability with existing USCG emergency frequencies, integration pathways for VHF and DSC data into the current R21 system, AES encryption standard support, and alternative delivery options if direct system integration is not feasible.

Questions for Vendors:
· How does your proposed solution handle antenna placement for both VHF/DSC and AIS Tx/Rx on towers with strict wind-loading and ice-loading limits?
· If the AIS subsystem experiences a critical failure, what hardware or software architectures ensure that the VHF/DSC lifeline communications remain 100% operational?
· How does the addition of AIS Transmit impact the existing power budget?
· In the event of power generation degradation, how does your system automatically prioritize power?
· Given the "build-to-cost" mandate, how easily can the AIS transmit capabilities be upgraded?
· Will your solution include satellite coverage past 24-50nm? If so, how many satellites cover the Alaska AOR and what is the median and average latency for that exclusive AOR?
· What are the send and receive ranges for VHF voice?
· For VHF data (e.g. DSC). What specific coverage areas TX/RX are you capable of/currently providing services, similar services?
· Does your system include remote diagnostic capabilities that function over low-bandwidth satellite backhaul (e.g., Iridium or Starlink)?
· What autonomous power solutions (Solar/TEG/Wind) do you offer for remote sites where the electrical grid is non-existent?
· What is your lead time for technician deployment to "Off-Road" or "Fly-In Only" communities?
· Do you maintain a local parts cache within the State of Alaska to reduce Mean Time To Repair (MTTR)?
· How does your hardware prevent "icing-related" signal loss or physical failure during heavy freezing rain or "hoar frost" events?
· Can you provide a detailed propagation map for AK and including the North Slope, accounting for "Earth Bulge" and low-angle signal loss at high latitudes?
· How does your equipment mitigate signal degradation caused by the Aurora Borealis or solar flare activity common in the Arctic?
· Does your equipment support interoperability with existing USCG emergency frequencies?
· How would VHF data be ingested and integrated into the current R21 system?
· How would DSC data be ingested and integrated into the current system?
· Does your equipment support AES encryption standards?
· If your equipment cannot be directly integrated into the current R21 system, what are the other options for delivering this capability to Coast Guard Command Centers?
