User-Friendly Operation At A Great Value
The eTrex H boasts Garmin's traditional tough, lightweight design to handle the rigors of your outdoor adventures. The eTrex H is even waterproof to IPX-7 standards which means it can survive being submerged in one meter of water for up to 30 minutes. The tough design has a thoughtful side as well for easy one-handed operation. You can operate your eTrex H with just one hand using its five buttons, all within easy reach of your fingers. The backlit display makes all your data easy to see at a glance so you can keep your eyes on the trail. The system is so intuitive that many users report being able to turn it on and become adept with it within the first hour of use. And, the eTrex is ideal for those on a budget who simply need the key features that make a GPS handheld useful for outdoor excursions. Because it is rugged and user-friendly, the eTrex H is just the right thing for your basic navigating needs.
Convenient And Resilient: It Will Find You, You Will Find It
The eTrex H doesn't just help you locate your position on the earth, it also makes it easy for you to keep track of it . Impress your hiking buddies by never fumbling around for your personal navigator. Thanks to its bright yellow case, eTrex H is easy to find in your boat or backpack. Or under the tent flap, or on the floor of your car...just about everywhere those little devices seem to slip sometimes. Unlike your cell phone, the eTrex H won't blend in to the bottom of your bag so well, which is a simple design solution to avoid lot of frustration. Plus your adventure can last and last — up to 17 hours on just 2 AA batteries. While you roam, you can store up to 500 waypoints in memory for easy retrieval. Just enter the point you want to go to, and eTrex H points you to your destination (no street or terrain maps). To get home, use Garmin's exclusive TrackBack® feature to reverse your track log and help you navigate back to your starting point. Both your bearings and your handheld GPS will be hard to lose.
WAAS Global Positioning.
You've heard the term WAAS, seen it on packaging and ads for Garmin® products, and maybe even know it stands for Wide Area Augmentation System. Okay, so what the heck is it? Basically, it's a system of satellites and ground stations that provide GPS signal corrections, giving you even better position accuracy. How much better? Try an average of up to five times better. A WAAS-capable receiver can give you a position accuracy of better than three meters 95 percent of the time. And you don't have to purchase additional receiving equipment or pay service fees to utilize WAAS.Having a GPS is useless if it keeps losing the signal, or reports your location with a wide margin of error. That's why Garmin has made its personal navigators compatible with a more accurate system than just GPS alone. With its high-sensitivity, WAAS-enabled GPS receiver, eTrex H locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. And, eTrex H will be able to accept a chip specially engineered for the European Union's upcoming Gallileo Positioning System, set to be running in a few years.
The origins of WAAS
The Federal Aviation Administration (FAA) and the Department of Transportation (DOT) are developing the WAAS program for use in precision flight approaches. Currently, GPS alone does not meet the FAA's navigation requirements for accuracy, integrity, and availability. WAAS corrects for GPS signal errors caused by ionospheric disturbances, timing, and satellite orbit errors, and it provides vital integrity information regarding the health of each GPS satellite.
How it Works
WAAS consists of approximately 25 ground reference stations positioned across the United States that monitor GPS satellite data. Two master stations, located on either coast, collect data from the reference stations and create a GPS correction message. This correction accounts for GPS satellite orbit and clock drift plus signal delays caused by the atmosphere and ionosphere. The corrected differential message is then broadcast through one of two geostationary satellites, or satellites with a fixed position over the equator. The information is compatible with the basic GPS signal structure, which means any WAAS-enabled GPS receiver can read the signal. The advantage is clear — whether you're in deep woods or just near tall buildings and trees, you can count on eTrex H to help you find your way when you need it the most.
