Z3801A Position Survey
I've had the opportunity to run the position survey function on five Z3801A receivers (with two surveys from a few of the receivers). All were fed from the same antenna, and the surveys were done over a period of about four months. Just for the fun of it, here are the lat/long/elevation shown by the five units:
Unit | Latitude | Longitude | Elevation |
N8UR #1 | 39 42 48.849 N | 84 10 20.343 W | 322.95M AMSL |
N8UR #2 | 39 42 48.902 N | 84 10 20.374 W | 323.48M AMSL |
MVUS #1 | 39 42 48.771 N | 84 10 20.291 W | 321.47M AMSL |
