Detailed description

Designed for marine navigation, the FURUNO GPS GP39 is a GPS navigator featuring a 4.2-inch color LCD display with a resolution of 480 x 272 pixels and a brightness of 700 cd/m². This unit integrates a 12-channel parallel GPS receiver capable of tracking 12 satellites simultaneously and supports SBAS (WAAS, EGNOS, MSAS) for improved positioning accuracy.

Navigation accuracy and performance

The GP39 delivers GPS positioning accuracy of 10 meters (95% of the time, HDOP≤4), WAAS accuracy of 3 meters (95% of the time, HDOP≤4), and MSAS accuracy of 7 meters (95% of the time, HDOP≤4). It operates on an L1 frequency (1575.42 MHz ±1.023 MHz) and updates position data every second. Cold start acquisition time is approximately 90 seconds, warm start 30 seconds, and hot start approximately 1 second.

Memory capacity and display modes

With memory capacity for 3,000 track points, 10,000 waypoints (with comments), and 100 routes (each with up to 30 waypoints), the FURUNO GPS GP39 allows storage of significant navigation data. It offers multiple display modes including chartplotter, 3D track (Highway), route tracking, navigation data, satellite status, and customizable pages (Digital, Speedometer, COG). Configurable alarms include arrival, anchoring, cross-track error (XTE), speed, WAAS, time, and distance. The MOB (Man Overboard) function enables quick position marking.

Connectivity and robustness

The GP39 features an NMEA0183 port (V1.5/2.0/3.0) and a USB 2.0 port for integration with other marine equipment and data transfer. It can output NMEA sentences such as AAM, APB, BOD, BWC, BWR, DTM, GGA, GLL, GSA, GSV, RMB, RMC, VTG, XTE, ZDA and receive RTE, TLL. The display unit is IP55-certified for water resistance, and the GPA-017 antenna unit is IP56-rated, ensuring resistance to water spray and 93% relative humidity at +40°C. Operating temperature range is -15°C to +55°C for the display and -25°C to +70°C for the antenna. The unit operates on 12-24 VDC. The display unit weighs 0.39 kg with bracket and 0.36 kg flush-mounted. The GPA-017 antenna weighs 0.6 kg and measures approximately 90 mm in diameter by 100 mm in height.

« FURUNO GP39: GPS expertise for essential navigation »

The FURUNO GP39 positions itself as a reliable standalone GPS navigator, ideal for recreational boaters and professionals seeking a precise positioning solution without the complexity of a multifunction chartplotter. Its strength lies in delivering essential navigation data—position, speed, heading, routes—on a clear 4.2-inch color display, even in varying light conditions.

In terms of installation, the GP39 is flexible. The display unit, with its IP55 rating, can be mounted in weather-protected locations, while the GPA-017 antenna, rated IP56, is designed for direct exposure to the elements. NMEA0183 connectivity enables easy integration with existing equipment, such as an autopilot or fishfinder, for sharing position data or receiving TLL (Target Latitude/Longitude) marks useful for fishing or object location. The USB port provides a convenient method for backing up and transferring waypoints and routes, a valuable feature for managing navigation data.

This model stands out for its robustness and ease of use, with dedicated buttons facilitating access to key functions such as MOB marking or display mode selection. It is particularly well-suited as a primary GPS system for marine navigation or as a reliable backup system. Its ability to display Loran TD coordinates is a specific feature that may be relevant for certain users or regions.
