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
Is this legal to put on a high altitude balloon? I ask because I’m looking for a tracker beacon for a balloon and I hear that the FCC frowns on cellular radios above a certain altitude.
For balloons, you must use 433MHz low power transmitter.
this is a very nice project, thanks for sharing
I am a graduate student studying a bird of prey, and I’m looking for help in adapting this code to use a sub GHz RF transceiver instead of the GPRS. I am new to developing microchips, but I would like to deploy a unit similar to this one in a place that does not have GSM coverage.
My PCB needs to have these capabilities: GPS data logging, RF transmitting (~800m range or greater), solar charging, <30 g. I also need to design several base stations to receive the data. Other researchers in my field are interested in a similar device, so I'd like to have my end product open source.
I would really appreciate any insight or help. Thanks!
Could you please give me the connections between the gsm module, msp430 and gps module
I would like to read more insight from you! Also I am going to share this blog immediately. Awesome!
Excellent site you have here. I’d really love to be a part of online community where I can get responses from other experienced individuals that share the same interest. Appreciate it!
Thanks for sharing your thoughts. I truly appreciate your efforts and I am waiting for your further post thanks once again.
