  Description    IESS-412 & NORAD ephemeris data can be loaded into the 
INTRAC-305. This data is primarily for Program Track use. 
HOWEVER the INTRAC-305 can use this data to generate an 
ORBIT MODEL for the satellite. The advantage of this is that 
the model is available immediately rather than after the 24hrs 
it would take if the INTRAC had to learn the orbit. The 
INTRAC is then immediately immune to long beacon outage 
or power failures. 
      The INTRAC will accept the ephemeris data two days either 
side of the data’s actual validity period. 
      The SGP/SDP modelling algorithms for the NORAD data will 
give slightly different pointing results for a given set of data. 
Except that the SGP4/8 algorithms are for Near Earth orbits 
and SDP4/8 are for Deep Space orbits. (Geostationary Orbits 
are SDP). The INTRAC will not allow a model to be made 
using the wrong type of orbit algorithm. 
      It is assumed that the user will know which NORAD algorithm 
applies for the data being used. 
      Menu Key 6 (Next Field) steps the selecting highlight through 
the seven selections. Once the required selection is 
highlighted pressing ENTER causes the model to be 
generated and the INTRAC to enter Tracking Mode. 
    Note  For more information on working with IESS-412 & NORAD 
data see page 68.
