In fact the problem is that I am reading the serial buffer FIFO, so it is &quot;old&quot; data.

In fact the problem is that I am reading the serial buffer FIFO, so it is "old" data.

<div>
<div class="content wysiwyg-content">
I am reading the GPRMC values, all is well. &nbsp;The date is correct, but the time is incorrect. &nbsp;It seems to be some sort of sequential counter instead.<br />
174051.000<br />
174052.000<br />
...<br />
restart the code and it resumes at:<br />
175634.000 &nbsp; -- the very first hour, minute and second is correct then...<br />
175635.000 &nbsp;-- the loop is about 5 seconds, so it should really say 175640.000<br />
...<br />
175659.000<br />
175700.000 -- so the counter looks like seconds! <br />
<br />
Puzzling and concerning because I need to know at exactly what time the GPS coordinates where taken.<br />
<br />
What am I missing?<br />
Thank you.

GPRMC time is incorrect

The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. A geographic information system (GIS) or geospatial information system is any system that captures, stores, analyzes, manages, and presents data that are linked to location(s). In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.
