3.3.1.1.3 Preset Satellites

This group allows the user to customize a list of 20 commonly used satellites. The LOCATE mode allows the user to select a satellite (3.2.2.3.1) from this “preset” list.

SAT#:

 

<SCR> THRU LIST, <ENTER> TO MODIFY DATA

This field identifies the list number (1-20) that is currently being displayed. When in this field, using the Scroll Up or Scroll Dn keys will move through the list.

To modify the data press the Enter key. The cursor will move to the NAME field.

NAME:

ENTER <ALPHANUMERIC> SAT NAME

This field allows a user to enter a name (up to 10 characters). See section 3.1.4 for instructions on how to enter alphanumeric data. After the name is entered, the cursor will move to the LON field.

If you do not wish to change the current name, pressing the Scroll Up key will move to the LON field. Scroll Dn will move back to the SAT# field.

LON:

ENTER LON IN <DDD.TT> FORMAT

This field allows a user to enter a satellite’s longitude in decimal format. See section 3.1.4 for instructions on how to enter satellite longitude. After the longitude is entered, the cursor will move to the INCLIN field.

If you do not wish to change the current longitude, pressing the Scroll Up key will move to the INCLIN field. Scroll Dn will move back to the NAME field.

POFF:

POL OFFSET <-90.0 - 90.0>

This field describes if the satellite's polarization axis is oriented non-orthogonal to the earth's equatorial plane. The sign convention is that described in 1.3.7.

INCLIN:

INCLINATION<0-12 DEG.> 0=>NON-INCLINED

This field allows the user to define whether or not the satellite is in inclined orbit and if so the number of degrees the orbit is inclined.

A number greater than zero implies that the satellite has an inclined orbit. A satellite identified as having an inclined orbit will enter TRACK mode following being STOREd.Entering an inclination of 0 implies that the satellite does not have an inclined orbit in which case the controller will not enter TRACK following

STORE.

BAND:

BAND <0-C 1-Ku 2-CK 3-L 4-X 5-Ka 6-S>

This field allows the user to specify the RF band associated with this satellite. This data is used by the tracking and autopeak algorithms to determine the effective bandwidth of the mount thus affecting size of movements made.

NOTE: the preset list only contains data about a satellite. With respect to the RC3000 there is sometimes confusion between the preset list and the list of STOREd satellite data (3.2.2.4). STOREd data contains both satellite and mount (azimuth, elevation, polarization) position data.
