Issues with Pointing to Satellites

  • Posts: 19

Hello,

I am trying to use KStars and EKOS to point my telescope at some GEO satellites but I am running into errors. One issue is that when I use Ekos to point to a satellite, it is way off from where the satellite actually is (see attached image). It seems that there is an incorrect generation of the RA and DEC from the TLE file and is causing the issue. In the image I am trying to point the telescope to "GOES 14" and the actual values should be around RA = 3h 57m and DEC = -7 deg 33'.

When I try to run a script and send in the RA and DEC to the telescope, I get a much more accurate result. However, the satellite always starts "tracking" even when I tell it not to. I have attached my code for this as well.

Any help in this would be much appreciated.

SOURCE CODE

# Set telescope to stop once on target
teleOnCoord = gimbal.getSwitch("ON_COORD_SET")
teleOnCoord[0].s = PyIndi.ISS_ON # Slew
teleOnCoord[1].s = PyIndi.ISS_OFF # Track
teleOnCoord[2].s = PyIndi.ISS_OFF # Sync
indiclient.sendNewSwitch(teleOnCoord)

# Send coordinates of target to telescope
teleRaDec = gimbal.getNumber("EQUATORIAL_EOD_COORD")
teleRaDec[0].value = ra
teleRaDec[1].value = dec
indiclient.sendNewNumber(teleRaDec)

# Wait for telescope to finish moving
while(teleRaDec.s == PyIndi.IPS_BUSY):
print("Scope moving to target...")
time.sleep(5)

print("Telescope on target")
