SN1 CD Relative Crustal and Atmospheric Velocity Components Data


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1978-12-09 to 1978-12-09


These experimenter-supplied, relative crustal and atmospheric velocity components data are on EBCDIC magnetic tape created on an IBM computer. Each 80-byte card image record contains time of reception of the Probe signal at the Canberra tracking station, expressed as seconds since zero hours UTC December 9, 1978; Cartesian components of the velocity of the Probe relative to the crust of the planet in meters per second; and two of the three Cartesian components of the velocity of the Probe relative to the ambient atmosphere in m/s. These components were derived by theoretical calculation involving the aerodynamic drag, the gravitational, and the inertial forces acting on the Probe. These data are on the Composite Data (CD) tape (which contains data from many experiments) created by the Unified Abstract Data System (UADS).
