RTK & corrections#06

RTK Fixed vs Float: what the status means

Fixed and float describe ambiguity handling, not a guarantee that every coordinate is correct.

RTK & corrections#05

RTK combines simultaneous base and rover observations with a real-time data link.

GNSS fundamentals#04

Code measurements provide a range estimate; carrier phase enables precise relative positioning when its ambiguities are resolved.

GNSS fundamentals#03

Multiple frequencies provide additional observations and help separate some atmospheric effects from geometric distance.

GNSS fundamentals#02

More constellations can improve observation availability, especially where part of the sky is obstructed.

GNSS fundamentals#01

GPS is one satellite constellation. GNSS describes the wider positioning ecosystem, including Galileo, BeiDou and GLONASS.
