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.
