Dear Eric, Thanks again for your kind support. It's our responsibility to provide the good performance product with better quality to our customers. It's really the great reward for all of your help to promote Macx-1. For dead-reckoning and 1PPS issue, we will double check and come back to you. The data sheet of GR-601 is also attached. You are much appreciated to review and improve it. Best regards, JY -----Original Message----- From: Eric S.

Find it on Also note that once we confirm a U.S. retail partner for you guys I will promote the product on my blog and Google+. As I have over 18,000 blog and G+ followers with a heavy concentration among programmers and engineers who are likely GPS customers, this is exposure many vendors would kill for. I have never plugged a product before; this will be your reward for a job very well done. The market you will be selling the Macx-1 into is much more interested in detailed technical information about the device than you are probably used to. The datasheet for this device should list the exact uBlox chip or module it uses, the NMEA version, and (most importantly!) a link to programming information about the GPS engine - uBlox's technical manual on programming the chip would do. One of our people already mentioned turning off the dead-reckoning feature so the device won't emit PPS after it has lost lock. One reason to link to the technical manual is so we can determine if this is really an issue; it might be the firmware stops emitting PPS in dead-reckoning mode, and that's exactly the sort of detail Macx-1 customers will be interested in. Another one of our people, Dave Taht, has inquired about customized cases. That gives me an interesting marketing idea. Look at the GPSD project logo at . That's a Linux penguin with GPS satellites orbiting it. You might want to think about doing a batch of these with the logo on the case - with a little promotion they'd probably sell like crazy to Linux fans. My offer to review and improve the English version of your technical documentation is still open. -- Eric S. Raymond
