Topic: Giving a GPS module the satellite information (Read 544 times) previous topic - next topic

Talmir

Hello

I am using an arduino to do some GPS work. But I do not want the GPS module itself to find the satellite information, rather I get the information from elsewhere and then I want to give the information to the module and let it use that to retrieve the current location.

Is this possible? I havent seen any arduino modules so far that have this function.

Thanks :)

Did a Google search for 'GPS module "load ephemeris"' and found these:

I have no idea whether it's possible, but I'm intrigued to know more about what you're proposing. My limited understanding of GPS positioning is that it's based on the analysis of highly accurately timed signals from multiple satellites. I can't imagine how this would work by taking signals from any other source. So, what is the satellite information you're referring to?

OP is referring to ephemeris as John Wasser noted.
This gives the Receiver information on where the satellites are (and they move) to cut down significantly on cold start up time.
