So far, I have been very impressed with the Pre-GO PPP's performance. I took it out for another field trip recently and had very nice 0-8 cm diameter groupings. HDOP has been consistently near and below 1.0. Geodetic engineers and surveyors would be pleased as punch.
I intend to define the outer bounds of the court and the service lines within. If I draw a 11x24m box with an 8.2x13m box smack in the middle, the test will be a success. These measurements are based on the regulation court dimensions outlined in the image to the right. I'm also considering measuring the accuracy of the altitude measurement. The net is 1.6m high and if I can get that measurement from the base of the net post to the top, that will be an interesting data point as well.
Added to this is the fact that, in general, GPS modules spit data out once per second. The Pre-GO PPP is no exception which means that, for a 1-hour test, there are 3600+ records to process. I'm using Python to interpret and plot the data but it still takes time.
Up next: RESULTS!
