What capability does a six-channel GPS receiver provide?

• A. Track six satellites with a single signal processor
• B. Track six satellites simultaneously with dedicated hardware per signal
• C. Generate six separate navigation solutions
• D. Support six different coordinate systems

Answer: (B)

The ability being tested is parallel tracking of multiple satellites using separate processing paths. Each channel handles one satellite’s signal, with its own processing resources, so a six-channel receiver can track six satellites at the same time. That dedicated hardware per signal is what makes simultaneous tracking possible, rather than trying to juggle all signals with a single processor. From all the tracked satellites, the receiver computes a single navigation solution, not six separate solutions. Coordinating six different coordinate systems isn’t related to how many satellites are tracked.
