Question:

Which of the following methods is widely used by the GNSS constellations to distinguish the satellites from each other at the GNSS receiver?

Show Hint

Think “PRN code per satellite” $⇒$ CDMA. Different codes, same frequency.
Updated On: Aug 29, 2025
  • Code Division Multiple Access (CDMA)
  • Time Division Multiple Access (TDMA)
  • Amplitude Division Multiple Access (ADMA)
  • Phase Division Multiple Access (PDMA)

The Correct Option is A

Solution and Explanation

GNSS satellites (GPS, Galileo, BeiDou and modern GLONASS) transmit on common carrier frequencies but with distinct spreading codes. Receivers separate satellites by correlating with each satellite’s PRN code—i.e., CDMA. (Legacy GLONASS also used FDMA, but CDMA is the widely adopted method across constellations.)
