which gps libraries to use to get a quick fix on the coordinates ? I will be using GPS signals and not GLONASS
If you are unfamiliar with GPS (sounds like that) and curious what "almanac" and "epemeris data" means, have a look at the detailed (and quite interesting) GPS book: https://www.u-blox.com/sites/default/files/products/documents/GPS-Compendium_Book_(GPS-X-02007).pdf
@abhishek2101 Have you tried the two other libraries that we already pointed you to?
As already explained, it is normal for a pure GPS chip to take a little while to get a fix after a cold start.
I haven't personally used the Pytrack GPS chip, so I have no idea whether it would be capable of saving almanac and ephemeris data for later re-use (either directly in the chip, or via some way to dump and then reload that data) for a quicker TFF, you may want to check the chip's data sheet for details.
@jcaron yes, you are right..I am using the newest libraries from the github repo but still it takes a very long time to get the initial reading.
@abhishek2101 You have already asked the question, and you already received detailed responses on this topic...
