Support for EGNOS: to be developed or implemented in the bluetooth devices already?

EGNOS is a system deployed in Europe in 2009 aimed to complement GPS and give his users an accuracy of ONE meter, also improving accuracy in woods and streets with tall buildings.

There are already some GPS receiver that support it - also search for WAAS, that is the American standard for the very same thing and - incredibly! - the two are fully compatible. Like this

or this, that with its 66 (!) channels states that can get a fix in 35 seconds with COLD start.

Ok, that was the foreword.
EGNOS developers made an open source library for Android! Here's an interview with a developer:

(the website is italian but the interview is in English, it's in the main box of the page)

I can't get from it if you would need a specific GPS receiver to use EGNOS, and if you do, like one of the above ones (or only the one named by that developer???) you would still need to implement the open source library into the app or if the info coming from the bluetooth EGNOS-enabled receiver would already have its info made more accurate by EGNOS.

Orux, is this matter of any interest to you?

Cheers and thanks.

Hi, febs;

If the external GPS is using EGNOS correction, OruxMaps will read the right position fixes, it is not necessary to implement anything, because in the NMEA sentences, the latitude/longitude provided should be right.

You can obtain additional information about the correction, but the positions are already corrected by the gps.

Thank you. The same would go for the GLONASS satellite system? That's the russian, complementary alternative to GPS. It is active globally since october, 2011. So far only the Iphone 4s (sold from november) has a chipset that support both GPS and EGNOS and uses both satellites at the same time, and some garmin GPS tools.

But, in the near future, I expect bluetooth GPS+EGNOS devices to be released. It would work the same way as in EGNOS?

Thanks,

Hi, febs;

yes if the device is NMEA compatible, because OruxMaps reads the nmea sentences from the device.
