Adjusting satellite elevation

SECTION FOUR - Service/Maintenance

You can change the speed averaging value at any time without affecting other navigation functions.

To change the speed averaging value:

1.At the RECEIVER INFORMATION screen, press the CURSOR PAD to highlight the GPS SPEED AV field, then press the EDIT key.

2.Press the CURSOR PAD left or right to select an averaging time in seconds of 1, 2, 5, 10, or OFF.

3.Press ACCEPT to make the change, or CANCEL to leave the option unchanged.

You can prohibit the 961 from tracking satellites that are close to the horizon and don’t provide high accuracy. The tracking of low satellites during GPS calculations is used primarily for technical applications, in which the 961 must track all visible satellites, regardless of how low they’re situated.

In other cases, however, when high-precision fixes are necessary, the advanced user can change this option to hide any low satellites. This option prevents the use of low satellites as sources of GPS position infor- mation, and avoids potential errors.

You can adjust this option to 0°, 5°, 8°, 10°, or 15°; however, Northstar rec- ommends that you leave this option at the factory setting of 10°.

To change the satellite elevation:

1.At the RECEIVER INFORMATION screen, press the CURSOR PAD to highlight the MIN SAT ELEV field, then press the EDIT key.

2.Press the CURSOR PAD left or right to select either 0, 5, 8, 10, or 15 degrees.

3.When done, press the ACCEPT key, or CANCEL to leave the option unchanged.

The software version of the GPS receiver is indicated in the GPS RCVR

REV field.

Setting DGPS operation

You can enable or disable the use of differential information.

1.At the RECEIVER INFORMATION screen, press the CURSOR PAD to highlight the DGPS SYSTEM field, then press the EDIT key.

2.Press the CURSOR PAD left or right to select either ON or OFF.

3.When done, press the ACCEPT key (or CANCEL to leave the option unchanged).

961X, 961XD specifications

NorthStar Navigation has long been a leader in marine navigation systems, and the NorthStar 961XD and 961X are no exceptions. These cutting-edge devices bring advanced navigation capabilities to both recreational boaters and professional mariners, ensuring precise positioning and enhanced safety on the water.

The NorthStar 961XD is equipped with a powerful GPS receiver that delivers exceptional accuracy, even in challenging environments. This is achieved through a combination of differential GPS (DGPS) technology and support for WAAS (Wide Area Augmentation System). These features enable users to achieve positioning accuracy within a few meters, which is crucial for safe navigation in crowded or complex marine environments.

One of the standout features of the NorthStar 961XD and 961X is their intuitive user interface. The devices boast a large, high-resolution color display that provides clear visibility in various lighting conditions, including bright sunlight. The menu-driven system allows users to quickly access essential functions, making it easy to plot courses, set waypoints, and track routes on the go.

Both models support advanced charting capabilities, including the ability to display vector and raster charts. The chart database can be easily updated via USB, ensuring that users have access to the latest navigational information. This is particularly important for long-distance cruisers navigating through unfamiliar waters.

Another significant feature of the NorthStar 961XD and 961X is their integrated fishfinder capabilities. With sonar technology, users can locate fish, understand the underwater topography, and enhance their fishing experience. This dual functionality makes the devices versatile companions for both navigation and hunting for the next big catch.

Connectivity is another important aspect of the NorthStar systems. Both models feature multiple connectivity options, including NMEA 0183, allowing seamless integration with other onboard electronics such as autopilots, radars, and AIS systems. This enhances the overall situational awareness and safety of the vessel.

Finally, the rugged design of the NorthStar 961XD and 961X ensures they can withstand the harshest marine environments. With water-resistant housing and durable construction, these devices are built to last, providing reliable performance year after year.

In summary, the NorthStar 961XD and 961X deliver a winning combination of advanced navigation technologies, user-friendly interfaces, integrated fishfinding capabilities, and robust construction. These features make them indispensable tools for anyone serious about safe and efficient navigation on the water.
