Pattern Altitude
I had a question regarding the most accurate GPS a few weeks ago, and the answers here were spot on.....
Now, the next question.
We have developed a locomotive simulator for training engineers which requires grade and curvature information to build the track for any given railroad. On US and Canadian railroads that's no problem. They have this information either in chart form or in electronic form (this is the easiest). The resolution of this information does not need to be, and never is very precise. I think WAAS gps data would be fine. I plan to do a trial this week by pulling a wagon on a hilly bike path, collecting data at 5 mph and 1 sample per second. I'll then survey this stretch with a total station surveying instrument for comparison. I'm, sure it will be just fine.
The railroad that is causing this experiment is in Bolivia.
The question is......
Does WAAS operate in all locations, or iis it only in "developed" countries?
