I have the latest Copernicus II DIP Module and tried to hook it up similar to how the hookup guide does it in the link (https://learn.sparkfun.com/tutorials/copernicus-ii-hookup-guide/all), but I am only getting the NMEA format with no numerical data displayed on my terminal, Tera Term. I've connected TX-B and RX-B to the breakout with a 4800 baud rate and checked that 3.3 V was the voltage going into the module. It says on the terminal that my GPS Quality has an invalid fix and the mode indicator (VTG) says that the data is not valid. Is it not in run mode? Is there a pin that needs to be held high that the hookup guide does not show or that I have just forgot? Any help would be greatly appreciated!</p>

If the PPS signal does not appear to be working, try increasing the PPS signal duration from its default 4200ns to 42000ns using the Trimble Studio software. A 4200ns pulse appears to be too fast for the RPi to notice.</p>

Minor Notes: The Trimble Studio Link above is stale: new link http://www.trimble.com/embeddedsystems/copernicus2.aspx?dtID=support<p>Future requests:
1. optional pad for an MCX connector instead of the SMA
2. silk screen for some of the pads on the same side as the chip
(once it was mounted to the bread board it was hard to probe
3. [ALTERNATE] bring Vcc, GND, TXB, RXB to board edge opposite the antenna</p><p>Otherwise, super pleased!</p></p>

This is a pretty common error that occurs with a weak power supply. Double check that, and if you are still having problems, contact techsupport@sparkfun and they can help you out further.</p>

I'm configured to use TAIP, and all queries to the GPS return <RXX ... 0000 ... >. I'm using the following antenna: https://www.sparkfun.com/products/177 and I connected the GPS/Antenna with a separated Power Supply.<p>This is my following setup:
XSTBY --> Vcc
OPEN --> GND
VBAT --> Vcc
The rest of the pins are unconnected.</p><p>Any ideas why is not working??</p></p>

Thanks for your interest. It did indeed turn out to be pin connection changes that were needed.</p></p>

There were pin connection changes, so you could potentially have a version which requires a different connection.</p>

I have worked through the tutorial l using a USB breakout set for 3.3v and tried Tera Term on a PC and coolterm on a MAC. In both cases I can connect TX to RX and see stuff I type on the keyboard echoed back to the terminal screen.
However when I connect to either TX-B and RX-B or TX-A and RX-A nothing shows on the terminal screen.
I have an active antenna connected, I am doing my test setup in side a house so reception will be a bit iffy, but I reckon I should see something.
Apologies if this comment should be posted somewhere else.<p>Any thoughts or suggestions welcome.</p><p>Peter_B.</p></p>

This module is using a grounded co-planar wave guide but "S" (the spacing between the signal trace and the top-layer ground) is 12 mil instead of 10. This works out to an impedance of 52.8 Ohms. It would have been better if the spacing was 10 mil, but still a LOT better than 70 - 80 Ohms!</p>

If you re-run your calculation with a 50 mil trace and 10 mil clearance between signal trace and ground you should get approximately 50 ohms. http://i.imgur.com/sEpKPAK.png</p>

https://www.sparkfun.com/products/11067<p>Both layouts appear to be 50 mil. The trace length is around 140 mil for both. This gives an impedance of roughly 75 ohms. The RF Input on the Copernicus is a 50 ohm input however. The trace width needs to be wider for 0.064" thickness with 1 oz copper thickness. Am I missing something here?</p><p>I've attached screenshot of existing setup:

In other words, I don't want to have to keep copying back improvements from SF, or if I make improvements, I don't want yours to fall behind. If there's a way to arrange that, I'm happy! (Sounded like it was just going to be duplicated over, but maybe it can be branched <em>into</em> your repo? I'm still somewhat new to GitHub, so apologies if that's what you meant).</p>

I have buy this Eval Boards GPS11858.
I link the pin :
pin------>input/output
VCC---->power 3.3V
GND---->power ground
TXA----->RS232
TXB----->RS232<p>It will return message, but without the GPS data.
Anyone can help me?</p></p>
