I found a tiny gem while browsing Github for MSP430 projects. This one is a GPS tracker based on a MSP430F5510 with a GPRS cellular connection for reporting and command input. The GPS is a FGPMMOPA6H from GlobalTop and the GPRS module is a SIM900 from Simcom.
The Github link has details from code to schematics and board files.
- An FRAM chip for input data buffering
- Resilient software architecture
- GPS/GSM operations controlled by timer interrupts which allows control of both sub-systems in the same time
- Great flexibility given by configuration variables
