Wish you all a very happy March EQUINOX day  20 March/22 sept 2009 On the
Equinox day and all measurement activity is done in the equinox day time at
RAMKUND of BHUJ.  
As Ramkund is perfectly constructed according to the Sun dial principles. E-W
N-S. and all constructions are perfect rectagular and perpendicular. for
measurement one do not need to manage any such directions and leveling But only
Shadow measurenets ONLY for sun dialing as we do in JANTAR MANTAR of Delhi or
JAIPUR. And that also will give the idea when tropic of cancer was passing there
at RAMKUND at that time many centuries ago. (23 14 51 N). 

Example of Latitudes longitude finding at the Local time. – for tropical of
cancer @ Local time you need to find the correct time when sun is on with no
shadows East or West. and need to be there at LOCAL time of 12:00 NOON which may
be 12 + MM depending on the place where you go – Longitudes. for Bhuj 12:52 PM

Hints: as Calculation of Latitude Longitude of the Place on Earth (eg RAMKUND)
we need to measure the angle of Sun. As on the Equinox day The sun is on the the
Equater, we need to go to the place on befor 12PM IST. 
At 12 PM IST see the Northern steps Shadow showing towards the West will be
seen. on the day. wait for the local time 12:00 NOON which will be at 12:52 PM
IST.
 
Measuring the Angle of the SUN : 

Similar Example of Latitudes longitude finding at the Local time. – for
tropical of cancer @ Local time you need to find the correct time when no
shadows East or West. and need to be there at LOCAL time of 12:00 NOON which may
be 12 + MM depending on the place where you go – Longitudes.
 
As at 12 PM IST shadow on the RAMKUND will be towords the west of NORTHERN STEPS
of the RAMKUND.  See when The shadow becomes perpedicular as line drawn in
steps diagrams, Shadow will be perfectly downwards in the plum line. 
 
If Above picturenot seen here ara attached with the email 1) Angle
Measurement@...  2) RAMKUND STEPS Shadow.jpg  
 
Now you find exact time when to there is shadow in exactly perpendicular line.
That say time is 12:52 than time difference is 52 minutes which is 52/4=13
dehrees means BHUJ is at 82.5-13=69.5 East.  LONGITUDE MEASUREMENT.
 
At this time you need to measure the lenth of the shadow at south steps as shown
in other diadram.  and measuer the angle of the sun . which is equal to the
Latitude of the place as the sun is on Equater. LATITUDE MEASUREMENT. 
 
as ramkund is constructed perfectly E W NS ans in perfect square and
perpendicular as reverse of PYRAMIS in the ground and exactly according to rules
Like pyramids accuracy.
 
Lenth of Shadow/height will give Tangent of the angle . tanke an anti tangent of
the figure you get by Shadow/height . thats the angle of the tilt of sun. Thats
the Latitude of the place RAMKUND.
 
As you are @ RAMKUND check how accurate is your experiment with figures of 
RAMKUND (23 14 51 N).
