Calculate satellite information for the Antenna Control Unit.
Information from two-line NORAD data is used to generate a file containing formatted satellite information. This file will be transferred to the Antenna Control Unit (ACU) for satellite tracking.
- SATID
- Satellite number
= 15427: NOAA-09 = 16969: NOAA-10 = 19531: NOAA-11 = 21263: NOAA-12 = 23455: NOAA-14 = 25338: NOAA-15 = 26536: NOAA-16 = 27453: NOAA-17 = 28654: NOAA-18 = 33591: NOAA-19 = 29499: METOP-2
- EPOCHYR
- Epoch year (Last 2 digits of year).
- EPOCHDY
- Epoch day (Julian day).
- EPOCHFD
- Epoch fractional day (Decimal point assumed).
- INCLINE
- Inclination. Entering "27503749" signifies a value of .27503749 revolutions.
- RTASCEN
- Right ascension of the ascending node.
- ECCENT
- Eccentricity. Entering "00121013" signifies a value of .00121013.
- ARGPER
- Argument of perigee. Entering "97265103" signifies a value of .97265103 revolutions.
- MEANAN
- Mean anomaly. Entering "21966907" signifies a value of .21966907 revolutions.
- MEANMO
- Mean motion. Entering "82840512" signifies a value of .82840512 radians/herg.
- PRINT(TERM)
- Output destination. This output contains the input NORAD parameters (satellite data), the output orbital parameters, and the calculated Antenna Control Unit string.
= TERM: Terminal. Output is sent to the user's terminal. = LP: Line printer. Output is sent to the printer defined by $PRINTER. = Filename: User-supplied filename. Output is sent to the user-supplied file with the extension .prt.
The above input parameters are used to calculate the orbital radius, the orbital inclination, the nodal period, the ascending node, the nodal time, and the nodal time correction. A report will be written to the line printer containing this information, the input parameters, and a string which can be used as input to the ACU.
NORAD generates a file of satellite information to be transferred to the ACU.The user-specified parameters are retrieved and calculations are made using this information to derive values relating to the nodal period and the orbital radius. The nodal time is calculated from the epoch fractional day. A string to be used by the ACU is also generated. This output is sent to a user-specified file, the line printer, or the terminal.
