3.7 WAAS Satellites
The ATS-6501 is capable of tracking up to two of the Wide Area Augmentation Systems
(WAAS) satellites. These satellites broadcast GPS signals with information that is useful in
improving the accuracy of GPS. The ATS-6501 automatically determines which of up to two
nearest satellites to track based on the current antenna position.
