Abstract
A global navigation satellite system (GNSS) device may receive GNSS correction data from a correction data source and obtain a first carrier-phase measurement of a first GNSS signal having a first carrier frequency, and a second carrier-phase measurement of a second GNSS signal having a second carrier frequency. The GNSS device may apply the GNSS correction data to the first carrier-phase measurement, the second carrier-phase measurement, or both. The GNSS device may, subsequent to applying the GNSS correction data, perform a wide-lane (WL) combination of the first carrier-phase measurement and the second carrier-phase measurement and determine whether the GNSS correction data includes an error based at least in part on whether a difference between a float ambiguity value for the WL combination and a closest integer exceeds a threshold value.
