Field Number: 
1) UTC time of GGA or GNS fix associated with this sentence
2) Mode 
     0 = residuals were used to calculate the position given in the matching GGA or GNS.
     1 = residuals were computed after the GGA or GNS position was computed.
3) Range residuals in meters for sat. used in navigation solution. Order must match the order of the satellite ID numbers in GSA. When GRS is used GSA and GSV are generally required.
