Wide Area GPS Enhancement

Wide Area GPS Enhancement (WAGE) is a method to increase the horizontal accuracy of the GPS encrypted P(Y) Code by adding additional range correction data to the satellite broadcast navigation message.Per a 1997 article, the navigation message for each satellite is updated once daily or as needed. This daily update of each satellite navigation message contains the range corrections for all the satellites in the constellation. Thus, more timely range correction information would be available for each satellite, resulting in increased horizontal accuracy. Potential improvements to the system include simplifying the upload procedure, uploading the data more often, and adding more monitor stations for better range correction.
