In an earlier post there was some discussion as to whether we in Australia received WAAS signals. I spoke to Magellan and they said nup. Tonight I noticed the W symbol on my satellite screen, and I looked up the footprints of the WAAS satellites:

So we can get 3 m accuracy with our GPSs here.Bob

Bob, sure we can receive waas birds in oz but we have no ground correction stations. The signal you are receiving is meant for another part of the planet and will degrade your accuracy so turn waas off.I may be mad but I'm not crazy

Yep turn it off, the unit supports it but there is no
infrastructure, it will degrade your signal.

The W satellite I am seeing is at 350 degrees from
Canberra. I am wondering if the Japanese MSAS satellite is working. They were planning to have six ground stations throughout our region. MSAS and EGNOS are meant to be compatible with WAAS. Can anyone come up with another explanation for a satellite at this location. Bear in mind that the Pacific WAAS satellite is located above the equator at 178E.

I know that someone in FNQ showed that they achieved greater accuracy with WAAS disabled, but according to the Raytheon site (they operate the system) even areas outside the intended reception area wont have accuracy degraded, and most likely will benefit.Bob

I agree with others Bob; in Aust turn WAAS off as we have no ground stations. My eTrex gets 4mtr accuracy anyway - why would you need or want more?Cheers, Jim
