What type of satellite appears to stay in one position in the sky?
The correct answer is B: Geostationary. What type of satellite appears to stay in one position in the sky is geostationary. Geostationary satellites orbit at the same rate as Earth's rotation, so they appear stationary. For amateur radio operators, this is important for satellite operation. Understanding this helps when tracking satellites.
Exam Tip
Satellite that appears stationary = geostationary. Think 'G'eostationary = 'G'round appears 'S'tationary. Geostationary satellites orbit at same rate as Earth's rotation, so they appear stationary. Not HEO, not geomagnetic, not LEO - just geostationary.
Memory Aid
"Satellite that appears stationary = geostationary. Think 'G'eostationary = 'S'tationary. Geostationary satellites orbit at same rate as Earth's rotation, so they appear stationary. Important for satellite operation."
Real-World Application
A geostationary satellite: It orbits at approximately 22,236 miles (35,786 km) above the equator, at the same rate as Earth's rotation. From the ground, it appears to stay in one position in the sky - you point your antenna at it and it stays there. This is what geostationary means - appears stationary.
Key Concepts
Why Other Options Are Wrong
Option A (HEO): Incorrect. HEO (Highly Elliptical Orbit) satellites don't appear stationary - they move across the sky. HEO isn't stationary.
Option C (Geomagnetic): Incorrect. Geomagnetic isn't a satellite orbit type - geostationary is the orbit type. Geomagnetic isn't correct.
Option D (LEO): Incorrect. LEO (Low Earth Orbit) satellites don't appear stationary - they move quickly across the sky. LEO isn't stationary.
