GPS receiver receives with signal from space 3 types of data - Almanac, Ephemeris, PRN code.
Can you explain those data types content and give approximate aquisition time for receiver "cold start", "warm start" and hot start"

Very Happy

No, sorry. Confused
There is little point in typing/copy/paste all the stuff here when it is easily available from other sources. It's a complicated subject which takes quite a bit of time to get your head round. Confused
However someone else may be prepared to do that for you.
