Erel and Agraham
thanbks for this library, I'm already running my navigation program and it works nicely. The satellites code becomes very easy with the new structured array which includes the "Used".
Still I'm not sure that EllipsoidAltitude is doing what it should - I get the same altitude all the time (usually there are variations of few meters as the gps stabilizes).
Please explain the difference between the two types of altitudes. all altitude calculations are with reference to a specific Geoid which is defined by each country or for an area, or by using the general WGS84.(see attached list)
What does "sealevel" use ?
