DGS-200 covers two topics in modern communication : GPS technology and GSM / GPRS technology.
In GPS module, the GPS receiver decodes the NMEA data strings from the satellites and output to software interface for the discussion of current position, speed, direction, time, etc.
In GSM / GPRS module, the usage of AT commands is introduced. Students can use software interface to send AT command to control GSM/GPRS module, send SMS message and make a phone call through headset interface, or access to the Internet.
When integrating both GPS and GSM / GPRS modules, the latitude and longitude data received by GPS module, this reference data will be sent to internet by GPRS service and reported in Google Map Website
