GPS Products

GPS products include satellite GPS receivers, chart plotters, fuel flow measurement devices, boat speed gauges, depth and wind instruments, autopilots and fish finders.

Satellite navigation technology is used in applications for transportation, recreation, survey, and personal information. Our GPS product range features cost effective and flexible configurations.

The latest GPS colour-display technology units are bright and feature sunlight-readable displays. The brand-new state-of-the-art receivers and powerful microprocessors, give you a quick and steady fix. They are waterproof and fully compatible with MapSource products like Pacific BlueChart®, Metroguide Australia and City Navigator Australia.

GPS applications are diverse and include commercial fleet tracking to low cost consumer "in car" and mobile computing GPS products.

Handheld GPS work by collecting information from a group of at least 24 satellites that constantly orbit the earth. A fix on three satellites is all you need to get a 2D position, with a fourth needed to calculate height. So unless you're inside a building or at either the North or South Pole, most units will help you find your place in the world.

Unlike some of the latest mobile phones with inbuilt GPS features, handheld GPS units don't need a mobile phone network to work, and unlike a car navigation device, they don't need an electronic map to be useful.

A handheld GPS continually monitors its own position and speed, ready to give you information on where you've been while you're carrying it, and where you should go. They are portable and designed to be carried for extended hikes.

Some units are similar in size to a rugged-design mobile phone, with several small buttons and a joystick to control the various settings. Some units are larger, with a bigger screen and wider buttons.

Saving a waypoint - such as a river crossing, interesting rock formation or even hard-to-find bookstore - is an ideal way to record any route markers or points of interest when you're out walking (they're called points of interest on car GPS units). Simply press a button or two on the unit. If you want it to record the entire journey, a tracking feature creates a snail-trail that evolves as you move. Once a track is created, you can save it as a route to use later or to guide you back to your original position.

Most units also have an alarm to let you know when you've arrived back at the starting position and if you move too far off the saved path.

If you have large hands, or are off to a colder climate and plan on using the GPS with gloves on, a larger unit could be a good option.

Some Handheld GPS have no mapping capabilities, but have a very good electronic compass and could indicate not only the barometric pressure but also the rate of change effectively giving you a portable weather station. This will probably lower the battery performance compared to other units due to the fact that they will be constantly collecting barometric pressure information, even when turned off.
