    Default GPS Photo Tracker

    I purchased GPS Photo Tracker to try out and I have a question about some of the slang and I was hoping someone could help me out with it.

    There is some settings where I can change to track at various intervals. Here are the two 10 second options. It is obvious that the first option saves more data but could someone explain what this all means.

    GGA/GSA/RMC/VTG->10 sec
    Only RMC->10 sec

    I googled this:

    GGA/GSA/RMC and VTG are all NMEA messages, you can read about that here http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=5214 - to summarize it's the data sent by a GPS receiver to the receiver, the fewer the messages the more you can store, RMC is generally enough for picture geocoding, with www.Locr.com for instance, but it you want full navigation information you will need the GGA/GSA/RMC/VTG combo.
    The farmer gave permission to place the cache in the field, but the bull charges.
