Your MMSI is a unique 9-digit identifier assigned to your vessel. You can obtain one through organizations like BoatUS or Sea Tow (for recreational vessels) or through the FCC (for commercial vessels). Programming is typically done via a computer before installation. Please ensure this step is completed before deploying the unit.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the MDA-1 require an external GPS antenna?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eNo. The MDA-1 features a built-in 50-channel GPS smart antenna, so no external GPS source is required.

It transmits at higher power (12.5W) and at more frequent intervals. Class B AIS, like the MDA-1, is designed for recreational and smaller commercial vessels. It transmits at lower power (2W) and less frequently, but still provides full receive capability so you can see all Class A and Class B traffic around you. For most recreational and smaller commercial boaters, Class B is the appropriate and cost-effective choice.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the MDA-1 compatible with my chartplotter?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe MDA-1 features both NMEA 0183 and NMEA 2000 interfaces, which are the two dominant marine electronics communication standards. This means it is compatible with the vast majority of modern chartplotters, multi-function displays, and navigation software from brands like Garmin, Raymarine, Furuno, Navionics, and others. It also connects to onboard PCs and radars.
