What does FHST mean in NASA
FHST stands for Fixed-Head Star Tracker. It belongs to the category of celestial navigation, and is a type of optical telescope used to determine a spacecraft’s orientation in space. FHSTs use the positions of stars in the night sky as reference points for calculating changes in the spacecraft’s orientation over time. This helps navigators determine their position relative to other objects in deep space, significantly boosting precision and accuracy over traditional methods like dead reckoning.

How do FHSTs Work? FHSTs consist of two components
an optical detector and an image processor. The optical detector takes images of stars and relays them to the image processor which then compares this data against known patterns or constellations stored in its database. This allows it to pinpoint any changes between different images taken at different times, thus giving navigators information regarding positional changes made by their craft during its journey through space. In addition, some models also have internal gyroscopes which allow for more precise measurements when necessary.
Essential Questions and Answers on Fixed-Head Star Tracker in "GOVERNMENTAL»NASA"
What is a Fixed-Head Star Tracker?
A fixed-head star tracker is an imaging device used to measure the position and orientation of stars in the night sky. It utilizes a two-axis detector head with a lens system that tracks stars by rotating and tilting according to their movement over time. This allows it to accurately measure the star's location in the sky, which can then be used for navigation, astronomical research, calibration tests, and other applications.
How does a Fixed-Head Star Tracker work?
A fixed-head star tracker consists of two main components – a two-axis detector head and a lens system. The two axes of this head rotate and tilt according to the movement of stars across the night sky. The lens system then captures images of these stars and uses them to accurately determine their exact position in space.
What is the purpose of using a Fixed-Head Star Tracker?
Fixed-head star trackers are used for a variety of purposes, such as navigation, astronomical research, calibrating tests, and more. By accurately measuring the locations of stars in the night sky, researchers can better understand how objects in our universe move and interact with each other.
Are there different types of Fixed-Head Star Trackers available?
Yes, there are various types of fixed-head star trackers available on the market today. Some models use motorized mounts to automatically adjust its orientation while others are manually operated by turning knobs or levers. Depending on your specific needs or requirements for accuracy, you can choose between various options when selecting a model.
How accurate is tracking with a Fixed-Head Star Tracker?
The accuracy level for tracking with a fixed-head star tracker largely depends on both its hardware capabilities as well as its software algorithms used for measurement calculations. Generally speaking however, most modern models offer remarkable accuracy levels within fractions of arc seconds per hour when operated correctly.
Are there any associated risks when using a Fixed-Head Star Tracker?
While using this type of device poses minimal risks compared to other astronomical equipment, it’s still important to take proper safety precautions whenever handling sensitive optical devices like these. Be sure to thoroughly read all instructions prior to operation in order to minimize potential safety hazards.
What kind of maintenance do I need to perform regularly on my Fixed Head Star Tracker?
To ensure your device operates at peak performance levels for long periods of time without requiring extensive repairs or maintenance down the line, it’s recommended that you clean your optics regularly using industry approved cleaning materials like anti-static screen cleaners or compressed air cans specially designed for optical devices such as these.
Can I use my existing telescope setup together with my Fixed-Head Star Tracker?
Yes! Most modern fixed head star trackers come equipped with standard telescope mounting plates which makes them compatible with virtually any existing telescope setup you may already have installed in your observatory.
Final Words:
In conclusion, Fixed-Head Star Trackers (FHST) are highly accurate and reliable instruments used for celestial navigation purposes aboard spacecrafts and other vessels travelling through deep space environments where alternative navigational aids may not be available or practical solutions. They provide many benefits such as increased accuracy compared to traditional methods like dead reckoning as well as improved safety measures due their ability to detect sources of potential hazards such solar flares, thus allowing navigators greater confidence when deciding on course corrections based on positional data provided from these sophisticated devices.
