Asunto: Re: [NAV-L] Position from crossing two circles : was [NAV-L] Reality check

As for Andres Ruiz' program, it's of an era that has left me way behind, and I have no hope of following what it does. A few words of explanation might help. Where do the numerical values at the end, two pairs of GHAs, Decs, and altitudes, come in?

George is a test for check the code:

+N/-S

-W/+E

TEST 1

20040219 UT1=2000

Data: 2 observations

Sirius GHA1 = 347.78;

 dec1 = -16.72;

 HO1 = 19.55;

Procyon

 GHA2 = 334.23;

 dec2 = 5.22;

 HO2 = 28.5;

Results: Lat & Lon of the two points

1(41.9918 º, -30.0057 º)

2(-11.9872 º, 85.1578 º)

TEST 2

20040219 UT1=2000

Data: 2 observations

Aldebaran

 GHA1 = 20.06;

 dec1 = 16.52;

 HO1  = 90-26.87;

Pollux

 GHA2 = 332.71;

 dec2 = 28.02;

 HO2  = 90-48.02;

Results: Lat & Lon of the two points

1(-6.9375 º, -6.8137 º)

2(42.0013 º, -29.9987 º)
