This architecture is instrumental for the very low price, small form factor and low power consumption. The trade-offs are longer acquisition time, lower sensitivity and less range than some traditional AIS receivers.\u003c\/p\u003e\n\u003cp\u003eField tests with conventional dual-channel AIS receivers showed, that under good conditions the dAISy HAT can be on par with some models (e.g. SmartRadio SR162) while still being outperformed by others (e.g. advanSEA RX-100). However, dAISy clearly outperforms all sub-$100 receivers that we have tested so far (Quark-elec, MarineGadget).\u003c\/p\u003e\n\u003cp\u003eOur observation is, that with a good antenna dAISy is well-suited to monitor local ship traffic. If you need maximum performance and are willing to pay for it, go with a receiver from the established brands.\u003c\/p\u003e","brand":"Wegmatt","offers":[{"title":"Default Title","offer_id":52217423003936,"sku":"fjs1787257934201","price":56.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/daisy-hat---ais-receiver-for-the-raspberry-pi_1.jpg?v=1787257939","url":"https:\/\/www.elmwoodbasket.shop\/products\/daisy-hat-ais-receiver-for-the-raspberry-pi","provider":"My Store","version":"1.0","type":"link"}
