What is WAAS

نوشته شده در سه‌شنبه ۳٠ مهر ۱۳۸٧ ساعت ۱۱:٥٦ ‎ب.ظ توسط محمد زراعت پیشه

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
