In our tests, overall performance of the dAISy-catcher is in a different league than our “old” dAISy receivers. At a sensitivity of better than -120 dBm at 20% PER, reception is typically only limited by the local RF environment.

AIS (automatic identification system) is an automatic tracking system for ships. Ships broadcast their position and other information over VHF. The dAISy-catcher allows you to receive these transmissions, enabling real-time tracking of nearby vessels.

The dAISy-catcher outputs the AIS data as a stream of ASCII messages, which are encoded in a marine standard format known as NMEA AIVDM sentences. This format is understood by applications and devices like chart plotters, marine data aggregators, and can be processed by many opensource libraries.

The dAISy-catcher can be operated as a USB device, or as a Raspberry Pi HAT.

Also check the accessories section for other items like RF filters and spacers
