GPS-> Stamp-> Internet -- How?

Concept: I want to have·a GPS/Stamp setup in a remote location be able to send Long-Lat and other event triggered alert messages·to my internet server. Would I use GSM or SMS?·I don't know enough about either one of these. Is there a charge for communicating? Where are people buying these chips?

Thanks

    Yes there is a charge, similar to a pager or cell phone those services.
    People are mostly using this to track vehicule fleets or their expensive toys.
    One option is to transmit via RF but if it is very far perhaps a microwave setup. By deduction your application is mobile so microwave might be the wrong choice. Please explain exactly what you are up to and the actual distance range and perhaps we could discuss this further and share ressources.

    I have several remote cameras. They could be placed anywhere in the state, normally in cell range, but ot near my home base. I want to know their location, when they recorded a picture, detected movement, or were disturbed.

    Thanks

    can basic stamp convert the gps longitude-latitude to x and y axes?

    There's something the amateur radio community uses called APRS.
    **note first that you DO need to have an operators license to use these bands....but once you are able to use these bands, all that's left is ettiquette.

    There's some generally accepted rules of who can use what and in what part of the band.
    Just do a search on APRS on the Net and you'll be surprised how much you find!

    In short, APRS (Amateur Packet Radio System), is connected to a GPS system (actual handheld device or some concoction of antenna/engines).· The data from the GPS is then transmitted to local repeaters (check your area coverage) and since all these repeaters are 'networked' (in the old fashioned way) then you could be hundreds of miles away and so long as you have repeater coverage, you could have a PC at home with a receiver on the repeaters' frequency collecting all the data from the network.
    The 'extra' equipment you run at each site sends out a specific ID for each packet....which, on your home PC, gets interpreted as a distinct symbol (I think you assign that).
    Lots of ppl use it for fun....some use it for 'fox-hunting' (sending radio beacons off by balloon and trying to locate them -- for prizes of course).

    Just note, that it's generally looked down upon to use these 'free' networks for commercial use.
    Other people put up these repeaters at their own costs, generally.·

    The only thing you have to do is get the equipment (Baycom rings a bell with me...not sure if they're still around) and your license (I'm in Canada...so it's through Industry Canada...FCC in the states I think!).

    Anyhow, it's not a bad way to do it if you don't want to connect some sort of Internet box to interface serial data to the Net (assuming you said your cameras are already 'net' ready).

    Anyhow....enough of this novel!!

    Just a correction to my previous post...



    APRS - DOES use packets...but it's not as I stated: Amateur Packet Radio System....it's actually, Automatic Position Reporting System....



    Close enough!! haha

    Ok, apparently I don't have enough to say about this.



    Be forewarned...that you need a 'site' license for all transmitting sites.·

    So, for each camera site that has one of these APRS transmitters, you'll need a license for that.· Same if you put one in your car (that one would be a mobile license).

    A pain...but...it's still somewhat cheaper than paying for cellphone text messages!...in the long run of course!

    If you are still planning on using a cellular method of communication (with is the method that I would recommend because of the speed which you can send data) I would and do use for sending GPS data and other messaging is a version of the GSM service which is GPRS. With GPRS you can send up to 5 megs of data per month for under $20 per if you don’t need this much data sent per month you may be able to find a plan from you GSM/GPRS carrier that better fits your needs.

    How GPRS works is the mobile/remote unit is assigned a TCP/IP address from the service provider and its data then is transmitted back to the service provider’s web server then you connect to their web server typically a TCP/IP socket connection to retrieve your data. It is straight forward and easily implemented.

    Just as a note AT&T, T-Mobile and Cingular are few carriers to check with and they also have modems or if you are having a problem finding what you need let me know I may be able to help you out I have sources for both OEM boards and stand alone modems along with GPS receivers.

    Hope this helps,

    I wanted to add that here in the United States it is illegal to use Amateur Radio frequencys for Business or commercial use.

    Yes, indeed.

    Up here where the bands are too congested (depends on your area I guess), unless you are interfering with other people, than they're not too likely to complain.· Of course, this is in the data sense.

    There are still many vets out there on the bands that try to moderate some of the bands/freqs...to some avail.



    To note on the side....up here (and I'm sure down there) you can't transmite encrypted data.

    This one always got me thinking....obviously something thrown back to the WW days.· Now what if someone, on the voice bands, start speaking pig-latin....isn't that a type of encryption?· maybe not! haha

    Wavecom makes wireless modules for GSM and CDMA networks that have M2M and GPS capabilities. The module measure about 1.25 x 2 x .25 inches.·The modules and related development/support·services are available through a distributor called AirDesk. http://www.airdesk.net/··Perhaps they can be of assistence to you.
