Abstract
A system and method for data entry by an operator uses data containing a first component and a second component derived therefrom, wherein the second component has error detection and correction abilities therein. The second component of the entered data is used to detect and correct error in the data entered for the first component. The first and second components are preferably characters (e.g., representing GPS position information) entered via a data entry device, while the second component preferably comprises Hamming code. The detection and correction can be performed after data entry and again after signal transmission.
