Delta-ionosphere compensated differential carrier phase (dcp) update

A global navigation satellite system (GNSS) device comprising:

• a GNSS receiver;
• one or more memories;
• and
• one or more processors communicatively coupled with the GNSS receiver and the one or more memories, wherein the one or more processors are configured to:
• obtain, via the GNSS receiver, measurement information regarding a first dual-band carrier phase measurement and measurement information regarding a second dual-band carrier phase measurement, wherein:
• the first dual-band carrier phase measurement and the second dual-band carrier phase measurement are of radio frequency (RF) signals transmitted by a satellite using a first frequency band and a second frequency band, and
• the first dual-band carrier phase measurement is performed by the GNSS device at a first epoch and the second dual-band carrier phase measurement is performed by the GNSS device at a second epoch subsequent to the first epoch;
• determine a change in an ionospheric error value from the first epoch to the second epoch based on a difference between the measurement information regarding the first dual-band carrier phase measurement and the measurement information regarding the second dual-band carrier phase measurement;
• and
• output an indication of the change in the ionospheric error value.
