🔍 Key Concepts

• Different GPS receiver types and how they handle multiple satellites • The meaning of terms like continuous, multiplex, and sequential in signal processing • Why having at least four channels is important for 3D GPS position and time fixes

💭 Think About

• Which type of receiver listens to several satellites at the same time, instead of one after another? • How would a receiver with only one RF chain typically share its time between satellites? • Think about which term suggests simultaneous parallel processing rather than time-sharing.

✅ Before You Answer

• Match the term that best fits simultaneous multi-satellite tracking • Eliminate any option that suggests time-sharing or rotating between satellites instead of parallel channels • Recall that a standard GPS position fix needs signals from at least four satellites to solve for latitude, longitude, altitude, and time
