Hello Arnold,
I already got in touch with NavSync. The data sheets of their GPS modules are
quite promising.
Recently, I ordered engineering samples of some GPS modules, namely the
CW12-TIM, CW45-TIM and
CW19. No results yet, but I will post details when the tests I had a change to
run some tests.
Regards,
Niels, struktur AG

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)
For more information contact NavSync"
