real time gps tracking device -

i working on product requires real time gps tracking.
searched on google collect information, got overview on how gps work.

now else need except gps receiver display on mobile through app (designed us) gps receiver attached product?
don't want whole navigation functionality, display located.

i know gps receiver continuously sends , receives signals satellites, how display on mobile app?
send info kind database , program app collect info there?

basically, need kind of connection between receiver , phone. since phones have own gps receiver, assume gonna track location of remote device. easiest way creating basic web service holds 2 pages in total.

• 1 update data receiver (i suggest use hash key prevent bots piss database)

• 1 data mobile app

depending on background , project needs can either use database keep location data or can use file (like xml file or that)

also need parse nmea code actual data. easier on web side (like in php). can pass nmea code server, parse it, record database/file. can fetch data mobile app using simple http requests.

if 2 devices close each other can use bluetooth don't know if there case make sense place additional gps receiver next smart phone :)
