INTRAC-305 TECHNICAL DESCRIPTION

strength is recorded and at the end of this phase the antenna is driven to that position and the INTRAC enters Standby.

At this point the peak may be confirmed manually and/or learning mode entered by selecting Auto New Model.

Remote	Remote Mode transfers control of the INTRAC to a remote
	terminal.
	It is selected with Menu Key 6 (Select Remote) from the Home
	menu. Once in Remote Mode only four functions are available
	from the INTRAC front panel. The emergency stop switch will
	inhibit the antenna drive as normal, the alarms can be
	displayed, Standby Mode can be entered and control can be
	returned to the front panel again with Menu Key 6 (Select
	Local).

USING IESS-412 OR NORAD DATA

The INTRAC-305 can make use of Intelsat IESS-412 11- parameter or NORAD ephemeris information in two ways.

	1.	The information can be used by the INTRAC to
		generate an INTRAC model of the satellites orbit.
		This model is then be used by the INTRAC as it would
		use a model it had learnt itself. This means that there
		is not the need for the 24hr learning period. The model
		is then updated as any INTRAC model would be.
	2.		The INTRAC can
		be commanded to Program Track using positions
		calculated from the ephemeris data.
	The IESS-412 and NORAD data sets can be entered either
	manually from the INTRAC front panel or from a PC. A stand
	alone program is available for loading the data file from a PC.
	This program can be used alone or in conjunction with the
	Remote Control Terminal RCM-4.
	A description of this program is given the appendices.
