What is the difference between absolute and differential GPS?
such as surveying and scientific research Differential GPS (DGPS) is a method of GPS positioning that improves the accuracy of absolute GPS by using a second GPS receiver. The second receiver is ...

GPS augmentation system
Also called a "differential GPS" (DGPS), an augmentation system compensates for those discrepancies by transmitting corrections to the GPS receivers either via satellite or terrestrial radio.

Accuracy of GPS total electron content: GPS receiver bias temperature dependence
Unfortunately, effects other than ionospheric dispersion also introduce differential delay differences ... We report here on an investigation of the temperature dependence of the GPS receiver bias.
