GPS-500 antenn NAIS-500 jaoks

The GPS-500 antenna is specifically designed for use with the Navico NAIS-500 Class B AIS transponder. It is the official accessory to ensure optimal GPS reception with this device.

The GPS-500 antenna is required when your NAIS-500 transponder is installed in a location where GPS signal reception is obstructed. This is often the case for installations:

Under the boat's deckInside a metal hullNear other electronic equipment that may cause interferenceIt ensures reliable and accurate satellite signal acquisition for consistent AIS transmissions.

The GPS-500 antenna connects directly to the NAIS-500 transponder via the external GPS antenna connector (SMA type) on the NAIS-500 unit. The connection is straightforward and secure.

The primary role of the GPS-500 antenna is to provide a reliable and accurate GPS positioning source to the NAIS-500 AIS transponder. It ensures the NAIS-500's internal GPS receiver maintains an optimal signal for transmitting the vessel's position, heading, and speed.

For optimal performance, install the GPS-500 antenna in a location on your vessel with an unobstructed view of the sky. This maximizes satellite signal reception and ensures the best possible positioning accuracy.

This antenna is specifically designed and sold to work with the Navico NAIS-500 transponder. Its use with other equipment is not guaranteed by the manufacturer and may not deliver the expected performance.

No, the GPS-500 antenna does not require a separate power supply. It is powered directly by the NAIS-500 transponder via the coaxial connection cable.

Yes, by ensuring stable and high-quality satellite reception, the GPS-500 antenna improves the reliability and accuracy of position, heading, and speed data transmitted by your AIS NAIS-500 system, which is critical for safety at sea.

Yes, the GPS-500 antenna is compatible with the NAIS-500 AIS transponder, which is a Navico product. This transponder is commonly sold and integrated into Simrad, Lowrance, and B&G systems. The antenna is therefore the recommended accessory for these installations.

As an external antenna designed for marine use, the GPS-500 is manufactured with materials suited to withstand marine conditions (sun, salt, humidity). It is recommended to follow the installation instructions to ensure its longevity.

It is important not to confuse them. The GPS-500 antenna is designed to receive signals from positioning satellites (GPS). A VHF antenna is used to transmit and receive radio communication signals and AIS data on VHF maritime frequencies. The NAIS-500 requires both types of antennas to function correctly.

The NAIS-500 does indeed have an internal GPS receiver. However, if the unit is installed in a location where the satellite signal is weak or blocked (such as a cabin, locker, or under a metal structure), the internal receiver will be unable to obtain a reliable position. In this case, the external GPS-500 antenna is required.

The GPS-500 antenna provides the signal to a high-performance GPS receiver integrated into the NAIS-500. It is a 50-channel receiver, compliant with IEC 61108-1, ensuring fast and accurate position acquisition.

Installing the GPS-500 antenna generally does not require specific tools. Connection to the NAIS-500 is made by hand-tightening the SMA connector. For mounting the antenna on its bracket, basic tools such as a screwdriver or drill may be needed depending on the chosen mounting method.

The GPS-500 antenna itself does not connect directly to the NMEA 2000 network. It plugs into the NAIS-500 transponder, which, once the GPS position is acquired via the antenna, transmits positioning data over the NMEA 2000 network (as well as NMEA 0183).

If the GPS-500 antenna loses satellite signal, the NAIS-500 transponder will no longer be able to determine its position. Consequently, it will stop transmitting position data via AIS. The error LED (ERR) on the NAIS-500 may light up to indicate the loss of GPS fix.

No, no software configuration is required on the NAIS-500 after connecting the GPS-500 antenna. The transponder automatically detects the external antenna connection and uses it as the primary GPS signal source.

The GPS-500 antenna is equipped with an SMA-type connector, designed to screw onto the external GPS antenna port of the NAIS-500 AIS transponder.

The GPS-500 antenna is designed to provide precise and reliable GPS positioning to the NAIS-500 Class B AIS transponder.

It is particularly essential if your transponder is installed in a location where satellite signal reception is obstructed, for example:
