These men were, first and foremost, astronomers, but the mathematical requirements of astronomy (and no doubt further interest) led to them developing many areas of mathematics, as such, I will refer to them just as mathematicians.
The vast majority of the works of the 'classical period' were however, in effect, Siddhantas.

  Trigonometric function - Wikipedia, the free encyclopedia
The next significant development of trigonometry was in India, in the works known as the Siddhantas (4th–5th century), which first defined the sine as the modern relationship between half an angle and half a chord.
The Siddhantas also contained the earliest surviving tables of sine values (along with 1 − cos values), in 3.75-degree intervals from 0 to 90 degrees.
The Hindu works were later translated and expanded by the Arabs, who by the 10th century (in the work of Abu'l-Wefa) were using all six trigonometric functions, and had sine tables in 0.25-degree increments, to 8 decimal places of accuracy, as well as tables of tangent values.

 History of Indian Astronomy   (Site not responding. Last check: 2007-10-20)
Mystical interpretations of the movement of stars and planets developed into astrological science, and astronomy grew into a major factor in the intellectual pursuits of different cultural periods.
Some seals of the Indus Valley period are believed to yield information of the knowledge available to those early settlers, as also the orientation of certain constructions clearly governed by such considerations.
The later siddhantas represent a considerable advance in astronomy- they were far more precise and calculations were accurate and easier than in the past.

While the Siddhanta deals with the calculation, etc., of planets, i.e., the astronomical part, the Hora deals with individual horoscopes, auspicious and inauspicious times for doing a particular thing and other matters of this nature.
The five Siddhantas, schools of systems of ancient astronomy, dealt with here are the Paitamaha, Vasistha, Romaka, Paulisa and the Saura.
In agreement with this estimate very different amounts of space are allotted to the individual Siddhantas in the body of the work.” But for Varaha much of the information regarding these ancient Siddhantas would have been lost to us.

 History on Podium: Varahamihira, a Great Iranic astronomer
It is a summary of five earlier astronomical systems, namely the Surya, Romaka, Paulisa, Vasistha and Paitamaha siddhantas.
This, coupled with a continuous immigration of Iranic settlers, led to the new Surya Siddhanta system gradually superceding the Harappan system around 400 AD.
Compared to the other systems of astronomy discussed by him, this is considered by Varahamihira as crude and undeveloped, and hence he gives very meagre information about it.

There are eighteen traditional systems (siddhantas) mentioned in Hindu astrology, which include the names of many of the greatest sages of Hinduism.
Perhaps the greatest astrologer of classical India, Varaha Mihira, in his Pancha Siddhantika, summarizes five of the Siddhantas: Pitamaha (Bhishma), Vasishta, Paulisha, Romaka and Surya.
In addition, the work of Rishi Parashara has endured in an expanded form as the Brihat Parashara Hora Shastra, which is the main text of Vedic astrology and contains all the essential features of the system used today.

It seems that towards-the end of the 5th century itself, people found that none of the five prevalent Siddhantas was yielding satisfactory result, that is, there were marked differences between predicted and observed astronomical phenomena.
The young Aryabhata (born 476) keenly noticed all this, made careful observations, and propounded astronomy on more scientific lines.
"When the methods of the five Siddhantas began to yield results conflicting with the planets and the eclipses etc., there appeared in the Kali age at Kusumapuri Surya himself in the guise of Aryabhata, the Kulapa expert in astronomy."
