| 1 |
The SCRAP Satellite tracker
program work great on my Windows 98, but does not
show the earth maps when I use the SCRAP program
on my Windows ME system. Please tell me what
other file I need to be able to use the SCRAP on
my Windows ME. |
The graphics are heavy into
OpenGL and it's extension GLUT. If you have a
system with an OpenGL graphics accelerator card,
it's possible OpenGL is not properly loaded. Try
loading the latest updated graphics drivers from
your video card vendor. |

All the graphics look just
fine except for the one marked "moon".
It's dimensionally stetched so the moon looks
like an ellipse insted of round. Otherwise they
look fine. |
The 3-D representation of the
moon is a recent addition. The egg-shaped moon is
a product of OpenGL Work is still being done on
the moon to not only round it out, but to rotate
it so that the proper lat/lon is point towards
Earth. |

SCRAP Update 29 Nov 2011 |
Packaged the file in a windows installer
package and provided a TRIAL mode period with limited
functionality. Improved APRS Internet downloading of data.
Tested product on Windows 7 and found fix for OpenGL freezing on
the Earth display. |

SCRAP version 12.0.0
Early release in December 2011 for 2012 |
Made improvements to the Antenna property
page, fixed a problem with non-display characters showing up in
the RS-232 output. Added to the 3-D Earth page the contact
cone for all enabled satellite contacts. Changed the COM
port initialization so that is only opens up the port on RISE
and shuts down the port on SET. This allows a single COM
port to be used for multiple contacts just so long as they don't
overlap in time. Also improved memory management for how
ephemeris data is stored for each satellite and cleaned up after
use. |

Compatibility fix for Windows 7 and VISTA |
On some Windows 7 installations the OpenGL
3-D Earth display
would freeze up and stop updating. This would happen
randomly and only on some Windows 7 and
VISTA computers. The fix is to simply change the start
ICON property for Compatibly and set to the current computer.
In the example (click on it to enlarge) set the "Run this
program in compatibility mode for: Windows 7. |
