Yes, its easy for most board GPS systems. We used the "navy protocol" or whatever it was; was very simple. It provided position information and at the same time stated the number of birds used (when more are used, greater accuracy). We threw out any measurements made with less than 4 birds. It was 9600 baud and odd parity, if I remember right. Most have several protocols; you can select the ones to use. --Bob ----- Original Message ----- From: "Tony Nixon" To: Sent: Sunday, November 24, 2002 9:14 PM Subject: [PIC]: GPS > Has anyone used a PIC to communicate to a GPS module? > > Any info on what data to expect? > > -- > Best regards > > Tony > > mICros > http://www.bubblesoftonline.com > mailto:sales@bubblesoftonline.com > > -- > http://www.piclist.com hint: The list server can filter out subtopics > (like ads or off topics) for you.
