CHAMP-BLACKJACK  

Definition

  • [Source: NASA JPL GENESIS, http://genesis.jpl.nasa.gov/zope/GENESIS/Missions/CHAMP ] In the year 2000, the German satellite CHAMP was launched carrying a new generation of GPS receivers, the "Blackjack", developed at JPL. The mission is managed by the Geophysikalisches Forschungszentrum (GFZ) at Potsdam (Germany) which is the other main data processing center for CHAMP radio occultations. The CHAMP Blackjack started collecting atmospheric profiles on April 6, 2001 and since then has been collecting up to 250 daily occultations during much of 2001. This receiver has enhanced capabilities over the older generation GPS/MET instrument which include "enhanced codeless" tracking (i.e., the ability to track the encrypted GPS signals), higher signal-to-noise ratio, and lower tracking in the atmosphere. The Blackjack GPS receiver is capturing high vertical resolution profiles over land and oceans and is providing data complementary to other sounding techniques. From this point on, the amount of data is expected to increase with ongoing enhancements of the receiver's software.
