Windowsill? So you have only partial view of the sky?
Then those 400ns sound about right. Said Jackson reported a couple
of months back that a LEA-6T showed about 1us (IIRC) jitter until
he avaraged the position for a couple of days (weeks?) to get the
real position. After that, the jitter was much better.
He also send some nice graphs of those measurements. You might want
to look for them in the archives.
