What Is WAAS? WAAS stands for Wide Area Augmentation System and is a system of satellites and ground stations that provide GPS signal corrections. As is true of the GPS satellites, there is no extra charge or equipment required to take advantage of WAAS. Because the new Earthmate USB GPS is WAAS-enabled, it is possible where WAAS is available to experience accuracy of under three meters for the majority of tracking time. How WAAS Works The system consists of roughly 25 ground reference stations positioned across the United States. These ground stations monitor GPS satellite data. Two master stations are located on each coast and these collect data from the reference stations and create a GPS correction message. This correction takes into account GPS satellite orbits, clock drift, and signal delays, typically caused by atmospheric conditions. The corrected differential message is broadcast through one of two geo-stationery satellites or satellites with a fixed equatorial position. Any WAAS-enabled GPS, such as the Earthmate USB GPS, is able to read this signal and benefit from the enhanced accuracy. WAAS Performance Considerations As is true for all GPS usage, the location and environment of the user will cause variability in WAAS performance. For instance, the position of the satellites over the equator make it difficult to receive the signals when mountains or trees obstruct a clear view of the horizon. Therefore, it is safe to say that WAAS provides the best performance in open-area situations. Unlike DGPS (differential GPS), WAAS does not require additional receiving equipment. Average Rating:
 Rating:  - Delorme Earthmate GPS LT-20I'm not at all satisfied with this product. I also own Microsofts GPS and I like it very much. I had the Microsoft one first and wanted to try this to see which is better. Rating: - not for truckersIf you are a truck diver this is not for you, it help a lillte bit but it gives sometimes routes that are not good for trukers like , thru mountains even trying to choose just interstates. Rating:  - Hands down the WORST option out there!I have owned the 2006 version of this program since it came out. I travel for a living and have used it on both coasts and in the midwest EXTENSIVELY. The ONLY thing it is good for is giving you a rough idea of how long your trip will take. THE MAPS ABSOULETLY STINK EVERYWHERE!!!!! There is a MAJOR 4 lane hiway near my home (Hwy 2 from Lincoln NE to Nebraska City, NE) that has been there for 5 to 10 years and it isn't even on the map (It still shows the old 2 lane hwy 2 and tries to redirect ...

NOT! First off I was led to believe it was ther 2007 version...it's not! It's 2006 Street Atlas. And they want $10 more to give you the 2007 SA update. That's not gonna happen! I 've tried everything I know and can't even make it open to MY city. It opens to Washington DC...I live in Southern CA. It lists my home on a street 1/2 a mile ... Read More Rating: - Several problems with GPS LT-20I recently tried this product and found several problems with the result that I will be returning it under Delorme's 30 day Money Back Guarantee - It guides you by saying the name of the street or exit to take however it is sometimes difficult to understand what is said - It does not seem to be as accurate as the navigator which is built into my Toyota. It can be off by 100 feet. By this I mean it thinks the car is located at some location point but in reality that point is 100 feet away. ... Read More |
