Hello,
I'm using a GARMIN 35 OEM serial GPS (mouse style with embedded antenna and RS232 interface). This kind of device is commonly used in fleet tracking applications (this one has been generously donated by one of our suppliers, and had a "Volvo" label on it ).
The project has nothing to do with this context, since it's intended for educational projects related to environment and such. For French speaking people, you can find more details here : http://www.pobot.org/-Radeau-environnemental-.html. Sorry for the others, but as you may know it's already quite a huge work to document and I've no time left for translation for the moment. Anyway, you'll find there a lot of illustrations and pictures in the articles which can give an idea of what all this is about.
Although the unit has worked properly at the beginning, since recently, all the GPRMC messages indicate not validated coordinates ('V' status instead of 'A' one). The GPS is used in the exact same conditions (same room, same environment,...). The only thing is that I've not worked on it for a long period (several months) since the time it worked fine.
Would anybody has some suggestion about the possible reasons, and remedies if any ?
Many thanks in advance and best regards.
