Technician exam question T8B06
Subelement T8, SIGNALS AND EMISSIONS· Group T8B
Which of the following are inputs to a satellite tracking program?
- A.The satellite transmitted power
- B.The Keplerian elements (correct answer)
- C.The last observed time of zero Doppler shift
- D.All these choices are correct
WhyThe Keplerian elements are an input to a satellite tracking program. Satellite tracking software calculates a satellite's position from its Keplerian orbital elements, the set of parameters describing the shape, size, and orientation of its orbit, answer B. Transmitted power (A) and a last-observed zero-Doppler time (C) aren't the orbital data a tracking program actually needs to compute where a satellite is, so D, which depends on all three being valid inputs, is also wrong.
