Scientists from ESA Member States have developed software for the acquisition and analysis of data, and will produce the final catalogue. The resulting mission data will be made available to the scientific community. Find out more about the various people, institutes and teams involved in the mission:. You can find more information about it here: Gaia Player Settings. Please Note: The selection you make here is just setting up a preset. The lighting system of Gaia has a lot!
Note that this selection is not set in stone - you can always change settings in the runtime tab and click the "Create Runtime" button again to override your runtime setup with the new values. After setting up runtime you are mostly finished with creating your Gaia Scene, if you are interested in Light Baking you can also perform the next, optional step in the Gaia Manager.
The Light Baking tab in the Gaia Manager is an optional step after the terrain creation that assists with baking the light for your scene. The tab offers two panels for the creation of reflection and light probes for your terrain, and two buttons for starting the light baking process. The "Quick Lightmap Bake" button just bakes the global lighting and reflection probe information of the scene, without baking any of the individual lights.
This is a very quick process that improves the visual look of your scene somewhat, especially how the shadows look when a HDRI skybox is being used. The "Full Lightmap Bake" button does a full bake including all lights, light and reflection probes in your scene. Gaia does not perform the light baking by itself, but rather triggers the internal light baking process of unity. If you run into the same issue there, it is an issue with the internal light baking process of Unity.
Unfolding the "Reflection Probes" panel gives you additional options to spawn reflection probes in a grid-like fashion across the terrain:. Please Note: Most of these settings are not Gaia exclusive, but are rather the same settings you would find on a manually placed reflection probe.
You can find out more about these probe settings in the Unity manual about Reflection Probes. When you click the "Generate Global Scene Reflection Probes" Button, a grid of probes will be created across your terrain according to your settings.
You can find the generated probes as a child object of the terrains in your scene. The "Clear Reflection Probe" button clears the generated probes again accordingly. Adding Light Probes. Unfolding the "Light Probes" panel gives you additional options to spawn light probes in a grid-like fashion across the terrain. Same as with the reflection probes, the "Generate" Button, generates a grid of probes as a child object of the terrains in your scene, and the "Clear" button removes those probes again.
Please Note: Alternatively you can also spawn light and reflection probes from the Gaia Spawner by selecting "Probes" as a resource. Did you find it helpful? Yes No. Home Solutions.

In this way, the stability of the telescope and its optical system will be maintained at precise levels. The other function of the sun-shield is to generate power for the spacecraft.
As the underside of the shield will always be facing the Sun, its surface will be partially covered with solar panels that generate electricity from sunlight. The sun-shield 'skirt' is the only deployable structure on Gaia. It consists of twelve separate panels that will be folded for launch. Once in space, the spacecraft will unfold these panels into a roughly circular disc, just over 10 metres in diameter.

The mission Gaia is orbiting the Sun-Earth system from the second Lagrange point L2, and the mission is designed to last for a nominal five-year period.

Communications and orbit tracking: Gaia has numerous firsts The end-to-end timing of the measurements must be highly precise. The platform and payload Gaia flight model during tests Gaia contains two optical telescopes that can precisely pinpoint the location of stars and split their light into a spectrum for analysis.
The platform The service module, referred to generally as 'the platform', contains the propulsion system and the communications units, essential components that allow the spacecraft to function and return data to Earth. The payload The payload module is housed inside a geometrical, dome-like structure called the thermal cover, and the payload consists of a single integrated instrument including the dual telescopes, with a common structure and a common focal plane.
The astrometric instrument is dedicated to the accurate measurement of stellar positions and brightnesses. Photometry: Continuous spectra in the band nm for astrophysics and chromaticity calibration of the astrometry.
