Hello, 
perhaps of general interest:
I found an intersting note via "GPS-world", new for me, 
but perhaps already well known,

telling that the Motorola M12+ is now replaced 
by an improved version, the CW12  from Navsync. 
("Designed as a functionally equivalent replacement for the 
Motorola M12+ GPS timing receiver").

Is the original M12+ not anymore available?
Is that now the state of the art on GPS timing receivers? 
What about the 1pps stability in comparison to the original 
M12+? 
Does anybody have more informations or already gained
practical experiences?
Is this module already available for a reasonable price 
for a private experimenter?

The original announcement from Navsync: 

"NavSync releases the CW12 OEM GPS receiver to replace 
the Motorola M12+ Oncore GPS receiver product line."

"November, 2005
NavSync Release Motorola M12+ Replacement
Aurora, IL  NavSync Ltd, a leader in low signal strength GPS
solutions, has released a functionally equivalent replacement for
the M12+ GPS receiver previously available from Motorola. Based
on NavSyncs CW25 OEM GPS receiver, the CW12 offers positional
accuracy (5m RMS), timing (<25 nsec to UTC) and tracking
sensitivity (-158 dBm) improvements to the M12+. The device
runs off a 3.3V supply and provides standard NMEA 0183 data
stream, 1 pps output and a variable frequency output.
....
Pricing for CW12: $57 (1K pieces)
