I added support for the Jupiter-T receiver to Lady Heather and noticed
something odd. On the sat position/signal level map sat PRN 9 was always being
drawn with a small black circle in the middle. I could not figure out what was
causing this... until I noticed that sat PRN 27 (which was visible, but
untracked due to low signal level) was being reported as being at the same
az/el as PRN 9. The black dot was PRN 27's location/signal level being
overlaid on PRN 9's
Analyzing some logged data, it looks like something about PRN27 confuses the
Jupiter-T Other receivers showed PRN27 in its proper position with a strong
signal. Doing a factory reset on the receiver (which flushes the almanac,
ephemeris, etc) did not change anything.
