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.
