Since 1992, the Air Force operates two specially equipped Gulfstream IV G for electronic intelligence (ELINT) - the S 102B Korpen. In the same year, one second-hand Gulfstream IV G-1159C was bought to serve as a VIP-transport. This aircraft got the designation TP 102A and the Air Force number 102001. (Text from this site.)
