Guest guest Posted May 16, 2001 Report Share Posted May 16, 2001 Hi I am a software engineer and I have been studying Hindu Astrology for the past 5-6 years. I am planning to develop an Astrology program with an emphasis on predictions,matchmaking etc which would be freely available for everyone. I am comfortable with the predictive part of astrology but I am not very much into the calculation part of it. I do have certain astronomical algorithms that could be used for calculating the planetary positions but using them I am not able to get the kind of accuracy and details that I want to achieve. I would be very grateful to you if you can guide me regarding where can I get such information or in case you have any chart generation source code and can share the code/logic with me. I can assure you that I would not be using it for any kind of commercial purpose. Thanks & Regards Raju Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 18, 2001 Report Share Posted May 18, 2001 Hare Krishna, Rayu. Please accept my humble obbeisances. All glories to Sri Sri Radha-Krishna. I was trying to do the same. It's a very good effort. For the calculation of the positions of the planets, that was the only thing that i could do, I was using VSOP87, a french system, which, in theory, has 1 arcsec of error for dates since year 2000BC to 6000 AD. I could use the ayanamsa to, in a very good way. There is a way to calculate the positions of the planets with the reference of any year, so you can do with the reference of 285 BC (Lahiri ayanamsa) or any other. If you want to, i have the calculations for Excel (Mac). The only problem of VSOP87, is that there are many calculations, but you can truncate, with the lost of accuracy, of course. I wold be very grateful, if i can colaborate to you in any way. I know few programs, but I feel my self as a good computer programer. Your servant: Luis.

Guest guest Posted May 22, 2001 Report Share Posted May 22, 2001 Hare Krishna, Raju. Jaya Sri Sri Radha Krishna. The name of the system is VSOP87, and it is found in internet. I use it with a book of Jean Meeus, called "Astronomical algorithms". In this book it is said how to calculate Julian Day, Sideral time of Greenwich (for those than doesn't know, sideral time is the position of aries 0 degrees, for any time; this is used to calculated the ascendant), etc. This system (VSOP87) consists of long series of periodic terms, which you have to add. I have the series, and I have the formulaes. It could be found on internet, but if you want to i can send you personally. I don't know specifically, what information do you want. Anyway, i'll check in the internet that site. Waiting for your answear, regards: Luis Quote Link to comment Share on other sites More sharing options...
