Features:

• Tracking of 1 or more satellites at a time, including sensor-mapping on earth (NOAA) and visual-range.
• Reads satellite data from norad-2 elements file.
• Download Kepler-data from Celestrak
• Handling max 4 Kepler files at a time
• Prediction next pass.
• Changing of satellite during "flight" possible.
• Changing of Kepler-data during "flight" possible.
• Uses jpg or gif-file for background
• Preferences file
• Prediction of start, stop, length and max. elevation
• Generation of picture (postscript) for monthly overview
• Driving rotor system:
  • RS232 output for feeding of rotor driving programs
  • Commands to GODIL decoder: The HRPT decoder described elsewehere on my pages can also receive positions, which are then translated into DiSEqC commands.
  • Support elevation/azimuth and X/Y rotors, with X or Y rotor at disc.
  • Connection via Ethernet, also directly to accesspoint (e.g. rotorcontrol in ESP)
  • Look ahead
  • Debug functions
• Calculation colinearity geostat. satellite with SUN.Calc. position up to 10x per sec.
• Zoom function

Usage:

xtrack [options]
   [options:]
     -f     <norad-filename> (default: norad.txt or what's in xtrack.ini)

     -rlon  <ref-pos lon> (default: 5)
     -rlat  <ref-pos lat> (default: 52)
     -rep_time <repetition time> (default: 1.0)
     -run_at_start
     -log <log_file> : use logfile for rotor results

     -m     <map-filename> (default: earthmap.gif)
     -ppl   <value> (default:  2)
     -max_azimspeed <value> in degr/sec, show err in degrees; def=0=no limit: show speed (predict only) 
  ppl=pixels per longitude.
  ppl=1 means: 1 pixel=1 degree, so size is 360x180 pixels.

Ethernet connection using rotorcontroller with ESP processor

Normal way via local net

• Xtrack, Preferences:
  • tab 'Run options': choose 'Use ethernet'
  • tab UART/Ethernet: set IP to , e.g. esp32-75EC4C
• esp module:
  • use in 'no access' mode
• PC:
  • use wired connection (PC-WiFi doesn't work for some reason???)

controller in esp=access point

• Xtrack, Preferences:
  • tab 'Run options': choose 'Use ethernet'
  • tab UART/Ethernet: set IP to 192.168.4.1
• esp module:
  • use in 'access' mode
  • Power-on
• PC:
  • set wifi on SSID of esp (defined in esp-code)
  • enter password (defined in esp-code)
