Question

write about Rashivalaya (Star Sign)

Answer 1

Answer:

mark me as brainlist

Explanation:

It is a group of 12 instruments with graduated quadrants

on both the sides. As mentioned in books, the purpose of

constructing these 12 instruments was to get the direct

determination of celestial latitude and longitude. The method of

observing celestial latitude and longitude is precisely the same

as that described for Samrat Yantra, and just as the quadrant

of the latter represents the equator, so also the quadrants of the

Rashivalaya represent the ecliptic at the moment of observation.

The instruments are constructed in such a scientific way that

one of these 12 is used, at the moment, when each sign of the

zodiac reaches the local meridian.
