Why was the hipparcos satellite able to make more accurate parallax measurements than ground-based telescopes?

The satellite doesn't have the problem of atmospheric distortion due to refraction and turbulence that you have on earth.

What technology has been used to investigate Saturn?
Ground telescopes and orbital satellite telescopes.
Is a satellite dish a form of radio telescope or antenna?
A radio telescope gathers and focuses radio waves, or electromagnetic waves outside the visual spectrum. A satellite telescope is sent outside the atmosphere to become a satellite of either the earth or sun, unless it is sent outside the solar system like the Voyager spacecraft. Many satellite telescopes carry several types of telescopes in one package to gather as much information as possible, like the Hubble.
Can the Hubble Telescope be seen through amateur telescopes?
Yes, if you know just where to look. You can see it with the naked eye. Go to spaceweather.com and click the "Satellite Flybys" link. Enter your ZIP code (in the USA) or enter your location to see a list of the visible objects. Low-altitude satellites are visible only when the Sun has set at your location, but the satellite is still in the light; that is, shortly after sunset or before sunrise.
What is the smallest satellite?
The smallest satellite was also NASA's first micro-satellite launched from Alaska on November 20, 2010. The satellite's name was FASTSAT or the USA 220.
What are the advantages and disadvantages of ground based telescope?
a normal telescope can be projected further then a space telescope because it is bigger and more of it a space telescope in in space which lets it see further into space and is more exspensive to make ect
What technology has been used to investigate Saturn?
Ground telescopes and orbital satellite telescopes.
How do telescopes and satellite help scientists?
it helps by moving humanity forwards
What do scientists use to study the Earth from far?
Satellite-based telescopes and sensors.
How many stars did Hipparcus measure?
Perhaps you mean the satellite Hipparcos. It measured the position of over 100,000 stars with high precision. It also measured the position of 2.5 million stars, with lower precision.
What is the main instrument for taking measurements of a tropical cyclone out at sea?
SATELLITE
How do you know what the solar system looks like?
Satellite/s, space probes, telescopes and many other ways.
What is the strongest evidence that CFC's are in the stratosphere?
Satellite measurements of light passing through the atmosphere
What is the strongest evidence that CFC are in the stratosphere?
Satellite measurements of light passing through the atmosphere
Is a satellite the main instrument for taking measurements of a tropical cyclone far out at sea?
yes
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere
What is the modern theory supported by additional evidence such as satellite measurements of continental movement?
Seafloor Spreading.
What is the name of the telascope used to look at stars?
If you mean, using the parallax method, that might be Hipparcos, or Gaia. From Wikipedia, article "Parallax":In 1989, the satellite Hipparcos was launched primarily for obtaining parallaxes and proper motions of nearby stars, increasing the reach of the [parallax] method tenfold. Even so, Hipparcos is only able to measure parallax angles for stars up to about 1,600 light-years away, ... The European Space Agency's Gaia mission, due to launch in 2012 and come online in 2013, will be able to measure parallax angles to an accuracy of 10 microarcseconds, thus mapping nearby stars (and potentially planets) up to a distance of tens of thousands of light-years from earth.
