Abstract: Systems, devices and methods are provided for determining the appropriate or desired geographical correction source for SBAS corrections. One aspect provided herein is a method. According to one method embodiment, a Space Based Augmentation System (SBAS) correction message is received from a selected SBAS satellite. It is determined whether at least one criterion is satisfied for using the selected SBAS satellite as a correction source and then processing the correction message received therefrom. A second SBAS satellite is selected from which to receive SBAS correction messages upon determining that at least one criterion is not satisfied for using the selected SBAS satellite as a correction source. One example of SBAS is the Wide Area Augmentation System (WAAS) used in North America. Other aspects and embodiments are provided herein.

Abstract: A method and system are provided for minimizing storage and processing of ionospheric grid point corrections transmitted from WAAS satellites in a global positioning system. Based upon a current location, the system creates a boundary around the current location and collects ionospheric grid point corrections within the boundary. The collected correction points are used to correct the position initially determined by a global positioning system.
