RTK Torch: Local base station corrections vs Point Perfect

Hi Jim, I’m from the UK, so your “0.27 inches or 8 cm” jumped out at me. I knocked up some python just to check the numbers. It’s 0.27 feet or 8cm… Here’s the code I came up with. The standard great-circle distance formula works great for large distances. For small distances, that rounds to zero and haversines are needed. import math import argparse from haversine import haversine, Unit def greatCircleDistance(lat1, lon1, lat2, lon2): # https://en.wikipedia.org/wiki/Great-circle_distance lat1_radians = math.radians(lat1) lon1_radians = math.radians(lon1) lat2_radians = math.radians(lat2) lon2_radians = math.radians(lon2) delta_lon = lon1_radians - lon2_radians cos_delta_lon = math.cos(delta_lon) sin_lat1 = math.sin(lat1_radians) cos_lat1 = math.cos(lat1_radians) sin_lat2 = math.sin(lat2_radians) cos_lat2 = math.cos(lat2_radians) central_angle = math.acos((sin_lat1 * sin_lat2) + (cos_lat1 * cos_lat2 * cos_delta_lon)) earth_radius =…
