Compared to single-frequency receivers, dual-frequency receivers are generally associated with which of the following advantages?

Dual-frequency receivers provide the advantage of fewer errors due to atmospheric effects, specifically ionospheric delay. In satellite-based positioning systems such as GPS, signals from satellites can be delayed as they pass through the atmosphere, particularly the ionosphere, which can distort the timing and accuracy of the signal received by single-frequency receivers.

By utilizing two different frequencies, dual-frequency receivers can effectively measure the delay caused by the ionosphere. The receiver can compare the time delay experienced at the two frequencies and consequently correct for the atmospheric effects, significantly enhancing accuracy. This capability is particularly valuable in environments where atmospheric variations can introduce significant errors in positioning data.

Other factors, while important in navigation, do not directly convey the same level of accuracy enhancement as the dual-frequency approach. Hence, the ability to mitigate atmospheric errors is a key advantage that sets dual-frequency receivers apart from their single-frequency counterparts.
