For positioning you need a GPS receiver. A wireless solution for this is a bluetooth GPS receiver. These are ideal for, for example, your iPad or tablet without internal GPS.

The GNS 3000 is an accurate Bluetooth GPS receiver.

When used on board of a metal vessel, the GPS receiver should be placed where it can see at least half the sky. For example behind the window. The GNS 3000 is not waterproof.

This GNSS receiver can simultaneously process and receive GPS and GLONASS signals. Thanks to the highly sensitive 99-channel SBAS (WAAS / EGNOS) GPS chips, it is possible to obtain an excellent GPS position. Routes and locations can be saved via the log function.
