{"product_id":"navico-gps-500-antenne-nais-500-ais","title":"GPS-500 Antenna for NAIS-500","description":"\u003cp\u003e\n    The Navico GPS-500 antenna is an essential accessory designed to optimize the performance of the NAIS-500 Class B AIS transponder. This external antenna provides a reliable and accurate GPS positioning source, complementing or replacing the NAIS-500’s internal GPS antenna. It is indispensable for installations where the AIS transponder is mounted in an environment likely to obstruct GPS signal reception, such as under the deck, inside a metal hull, or near other electronic equipment. By ensuring superior satellite signal acquisition, the GPS-500 antenna guarantees that the NAIS-500’s 50-channel internal GPS receiver, compliant with IEC 61108-1, maintains an optimal position fix for consistent and accurate AIS transmissions.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and performance of the GPS-500\u003c\/h3\u003e\n\u003cp\u003e\n    The GPS-500 antenna connects to the NAIS-500 transponder via a dedicated SMA connector, providing simple and secure integration. This setup allows the antenna to be positioned in the most unobstructed location on the vessel, maximizing sky visibility and GPS signal quality. Robust GPS reception is critical for Class B AIS systems, as it ensures not only the transmission of the vessel’s position coordinates but also accurate calculation of heading and speed. Using an external antenna like the GPS-500 enhances the overall reliability of the AIS system—a critical feature for maritime safety and regulatory compliance. While systems such as the B\u0026G Zeus³S or Garmin chartplotters often integrate high-performance GPS receivers, adding an external antenna to the NAIS-500 ensures equivalent or superior performance under challenging conditions for the specific AIS function.\n\u003c\/p\u003e\n\n\u003ch3\u003eReliability and marine environment\u003c\/h3\u003e\n\u003cp\u003e\n    Although the exact environmental specifications of the GPS-500 antenna are not detailed independently, it is designed to operate in synergy with the NAIS-500 AIS transponder, which itself is IP67 certified for water resistance and capable of operating within a temperature range of -15 °C to +55 °C. This compatibility implies that the GPS-500 antenna is built to withstand the rigors of the marine environment, ensuring consistent durability and performance in the face of weather, spray, and temperature fluctuations. Investing in a dedicated external GPS antenna like the GPS-500 is a proactive measure to maintain AIS data integrity, essential for collision avoidance and the visibility of your vessel to other waterway users.\n\u003c\/p\u003e","brand":"Navico","offers":[{"title":"Default Title","offer_id":53723745124692,"sku":"000-13613-001","price":107.53,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_e6111eb1-0b57-4210-8d4d-43f45662bc68.png?v=1772639512","url":"https:\/\/skysat.fr\/en-gb\/products\/navico-gps-500-antenna-for-nais-500-ais-4","provider":"Skysat","version":"1.0","type":"link"}
