There are a number of differences between multi-band and single-band RTK GNSS receivers.
Primarily, single-band receivers can only obtain one frequency band from satellites, whereas multi-band receivers work with several frequency bands.
This has a knock on affect to the performance capabilities of each type of receiver. For instance, multi-band receivers can achieve a fixed position quicker and have a longer baseline (distance between base and rover).
Typically, multi-band receivers are more expensive than single-band receivers.
