Name |
Satellite name |
Lat |
Latitude of ground track |
Lon |
Longitude of ground track |
Alt |
Altitude of satellite above earth (kilometers) |
Azm |
Observer look azimuth to satellite |
Elev |
Observer look elevation to satellite |
RA |
Right ascension of satellite, for sky map reference |
Delc |
Declination of satellite, for sky map reference |
Range |
Distance from observer to satellite (kilometers) |
RRt |
Range rate; changing of Range in time; for Doppler shift (kilometers per second) |
Vel |
Velocity of satellite (kilometers per second) |
Direction |
Ascending - satellite moves from South to North; Descending - North to South |
Eclipse |
Posible values are: Penumbral / Umbral / No (satellite is illuminated) |
MA (phase) |
Mean Anomaly (0-360 degrees) and AM-SAT phase (0-255) of satellite counted from perigee |
Orbit # |
Orbit number counted from first perigee |
Mag (illum) |
Visual magnitude and illuminated fraction in percents. Posible values are: 'not visible' (satellite is below the horizon), 'eclipsed' (satellite is in umbral eclipse), 'X.X* (80%)' (magnitude and illuminated fraction, * - penumbral eclipse) |
Sun and moon data similarly as satellite...
Search period |
It can be set automatically (as period before/after the current moment) or manually (as free time range) |
Illumination required |
Check it for visual passes or uncheck for radio amateurs purposes |
Sun elevation |
For visual passes check it and define maximum sun elevation |
Satellite elevation |
Minimum satellite elevation during the pass |
Minimum flare magnitude |
Now Orbitron can calculate flare magnitude. You can set limit for this parameter to catch brightest ones. |
Brief output |
If checked 1 line of output is generated for event (MET), if not each event is described by 3 lines (AOS, MET, LOS) |
Minimum pass magnitude |
You can check that option and define minimum pass magnitude (remember that mag of -1 is brighter then 1); minimum magnitude equal to 3 gives you brightest passes (mag 3..0 and under); NOTE: maximum magnitude of pass often occurs in different moment than MET |
Ignore if magnitude is unknown |
It's extension to option above, if checked satellites with unknown magnitude can be also listed. |
Search passes for |
Define for which satellites Orbitron makes passes calculations |
Azimuth, Elevation, Receive/doppler, Transmit/doppler, Dnlink mode, Uplink mode |
Values from these fields are sended to driver. |
Dnlink, Uplink |
Frequiencies list. You can also type your own value. Existing ones are taken from notes files, please check NOTES/00000.TXT for more details. |
Driver |
List of available drivers. 'WispDDE' is a build-in one, other drivers must be listed in Config\Drivers.dat file (driver's file names without extension, line by line). |
Run selected driver and start sending data (icon) |
After pressing this button, Orbitron will try to run driver and starts sending tracking data. At the first time you will be asked for location of driver's EXE file. |
Tracking object |
Choose object for track. |
Lock active satellite (icon) |
Orbitron normally sends data for the active satellite to the rotor/radio driver. The 'Lock Active Satellite' button ensures that this data stream continues uninterrupted even if another satellite made active. When this button is released, the data changes to that for the now active satellite.
