Thank you for using OGTS!
Open GPS Tracking System is an alternative to OpenGTS with a user friendly GUI and easy installation.
OGTS is written entirely with Java/JEE/JPA/SWING, currently, it supports French language.
The communication between the GPS and server is made by plain text messages(TCP) and it follows the NMEA protocol.
Currently OGTS supports only TK-103 protocol, if your GPS doest support TK-103 protocol please send me the GPS reference I'll add it for you.
Please...
