GPS: Precision at the service of your navigation

GPS is much more than just a position indicator; it's the cornerstone of your navigation, your safety management, and the optimization of your performance at sea. At Skysat, drawing on our experience in offshore racing, we select robust and precise GPS devices capable of withstanding the most extreme conditions. Discover here the models and technologies that will guarantee you a reliable position and worry-free navigation.

choose the right GPS receiver

The quality of the GPS receiver is paramount for fast and accurate position acquisition. Factors such as the number of channels, receiver sensitivity, and compatibility with augmentation systems (WAAS, EGNOS) directly influence performance. A good receiver will minimize signal loss, even in challenging conditions (bad weather, urban areas).

• Garmin Gpsmap 86sci GPS Receiver : Integrates multi-band GNSS technology for increased accuracy.
• Furuno GP-39 GPS Receiver : Standalone solution with 4.2" LCD screen and NMEA0183 output for connection to other equipment.
• Raymarine RS150 GPS Antenna : High-performance GPS/GNSS antenna compatible with SeaTalk NG, offering optimal positioning accuracy.
• Simrad GS25 GPS Antenna : 10 Hz GPS/WAAS antenna for fast and accurate acquisition of position data.

the importance of system integration

A high-performance GPS is not enough; its integration within your navigation system is crucial. Compatibility with NMEA 2000 and NMEA 0183 standards allows for seamless data exchange with your other instruments (chartplotter, autopilot, VHF radio). Proper integration ensures increased redundancy and reliability.

• NMEA 2000 : Digital communication standard offering simplified connectivity and greater bandwidth.
• NMEA 0183 : An older serial communication standard, but still widely used, requiring more complex configuration.
• Multiplexer Interfaces : Allow NMEA data to be managed and distributed between different devices.
• Chartplotter compatibility : Ensure GPS compatibility with your chartplotter for accurate display of your position on nautical charts.

key selection criteria

Choosing a GPS depends on your specific needs. Consider the size of your boat, the type of navigation you do (coastal or offshore), and your budget. A handheld GPS can be a simple and economical solution for occasional coastal navigation, while an integrated system with an external antenna will be better suited to intensive offshore sailing.

• Positioning accuracy : Maximum permissible error depending on your navigation type.
• Robustness and watertightness : Resistance to marine conditions (humidity, vibrations, shocks).
• Electricity consumption : An important factor, especially for long journeys.
• Ease of use : Intuitive interface and ergonomics adapted for use at sea.

💡 Skysat's advice

When installing your GPS antenna, be sure to choose a location with an open area, far from any potential interference (masts, radar). A reception test at sea is essential to validate the installation and guarantee optimal performance.
