SACC-BLACKJACK
Definition
- In the year 2000, the Argentinean satellite SAC-C was launched carrying a new generation of GPS receivers, the "Blackjack", developed at JPL. The mission is managed by the Argentinean CONAE, which will be the other main data processing center for SAC-C occultations. On July 7th. the SAC-C Blackjack captured its first profile and has since been collecting up to 250 daily occultations during much of 2001. This receiver has enhanced capabilities over the older generation GPS/MET instrument that 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.
