Which of the following statements regarding GPS satellites is accurate ?

Select your answer for: Which of the following statements regarding GPS satellites is accurate ?
Show answer

Answer: D. All of these

Explanation

GPS satellites operate at a nominal orbital altitude of approximately twenty thousand two hundred kilometers. Orbital inclination of GPS satellite axes is set precisely at fifty-five degrees relative to the equator. Satellites broadcast dual L-band carrier signals at fifteen seventy-five point forty-two and twelve seventy-six point six megahertz. Global positioning system architecture is designed with specific orbital and radio frequency parameters. L-band radio frequencies penetrate the atmosphere effectively while carrying precise satellite timing data. Orbital inclination ensures good polar and equatorial coverage for military and civilian receiver users.

Surveying and navigation equipment manufacturers design dual-frequency receivers to process L1 and L2 signals. Aerospace engineers account for orbital altitude and inclination when planning satellite constellation maintenance. Precise frequency transmission standards allow GPS receivers to calculate carrier-phase positioning corrections. Option A is correct but incomplete because orbital inclination and signal frequencies are also accurate facts. Option B is correct but omits the nominal altitude and dual L-band signal specifications listed separately. Option C is correct but fails to mention the twenty thousand two hundred kilometer orbital altitude fact.
