Tycho Brahe discovered a supernova in the constellation Cassiopeia. He is still considered the greatest observer of the pre-telescopic era. The instruments he used to measure the positions of the stars and planets were state-of-the-art for his time and his observatories were comparably colossel in scale to our modern-day observatories. He was convinced that while the Sun still revolved around the Earth, the other planets revolved around the Sun! He was still unwilling to completely give up the old view of the solar system in spite of his own precise measurements which showed the ptolomaic system to be flawed.
Tycho's main apprentice Kepler, took his mentors' measurements to the next level, where he not only fully established the Sun-centered solar system, but went beyond Copernicus in explaining how orbits are elliptical, and how bodies move faster the closer they get to the primary (sun) in its orbit.
Later Newton would incorporate Keplers Laws of planetary motion in formulating his theory of gravity. He said "I stand on the shoulders of giants". He is referencing Tycho, Kepler, and Galileo. Newton's laws have had a major impact in opening up the industriel age, not to mention the Space age.
Tycho Brahe was an interesting and rather eccentric person. You should read more about him.

Tycho Brahe really didn't "discover" much. He was a methodical observer of the heavens and developed very accurate measuring instruments. He built the largest sextant in the world (at the time and perhaps even today) in order to make his accurate measurements...most especially in tracking the motions of the planets. As far as I know, nobody really developed anything better based specifically on the designs of his instruments. His accurate measurements were only bested with very different instruments, namely telescopes.
Brahe's accurate measurements, as you probably know, allowed Johannes Kepler to develop his Laws of Planetary Motion...and that literally reshaped our view of the solar system and the universe. He was a great man, to be sure, but I'd be hesitant to say that anything he did lead to new technologies, rather a much better understanding of the solar system.
Edit: Perhaps he did develop accurate clocks as mentioned above...good timing is a part of measuring planetary motions. Something to check out anyway.
