Abstract
An approach to joint processing of GNSS signals to determine a receiver location and common mode bias associated with grouped records corresponding to GNSS signals. In this regard, a receiver may acquire signals from a GNSS space vehicle over a relatively long period of time. In turn, records corresponding to received signals may be stored and grouped. The grouping of records may be based on assumptions of a common-mode bias for certain records (e.g., records acquired within a given duration of an observation time period). Upon acquisition of a suitable number of records, an over-determined system may be established that is used in iterative processing to solve for location and/or bias values associated with the respective common-mode bias for each group of records. As such, improved receiver performance may be realized.
