METHOD, PERFORMED BY GNSS RECEIVER, FOR PROCESSING DATA SIGNAL, AND RECORDING MEDIUM AND GNSS RECEIVER SYSTEM

摘要

Disclosed is a method for processing a data signal, the method comprising the steps of: receiving a data signal from at least one GNSS satellite and obtaining a pseudorange of a GNSS satellite by using the data signal; obtaining a pseudorange acceleration, based on the pseudorange; and applying a variance to the data signal, the variance obtained by assigning a weight according to a noise model to the pseudorange acceleration.
