Experience with Parallax GPS receiver module
I just purchased the Parallax receiver module (Item code 28146) and was wondering if anyone had any experience with it. I copied over the demo code from the website and am communicating with the BS2 and getting all the right displays in the debug window.
Every now and then I will acquire a signal and get some readings but even in clear view of the sky it is jittery. I did some research on the module before purchasing it and noticed it used the SiRF III chipset which appeared to be a very well known and reliable chipset but why can't I seem to acquire a signal even after waiting up to 15 minutes. Would this have anything to do with the antenna that is mounted on the module? I'm running it with the /RAW Pin pulled low to continuously monitor incoming data. Also I'm only interested in monitoring speed, lat, and long, though I don't think that would effect how the receiver links up with the satellites.
Any ideas on how to obtain a stronger or more reliable signal? Would a different antenna help?
Thanks
