Hi there, have used Emlid Studio in Kinematic mode to process two RINEX files from GNSS receivers that are essentially in a moving baseline mode.
To be more specific, the GNSS receivers were mounted on a ship at the bow and stern, which whilst moored alongside a pier was subject to the effects of tide and wash of passing ships etc.
I am trying to achieve true heading by outputting from Emlid Studio in E/N/U-Baseline format, then doing some math to calculate the heading based on the dE & dN output. However, when comparing with online PPP processed data and computing azimuth from Latitude and Longitude I get some 2° bust in heading.
Normally on a UTM derived E/N output we would apply a convergence value to convert from Grid North to True North, but that is a function of the distance from the central meridian. How does one apply the equivalent of this convergence to ENU coordinates to get True Bearing? Do I need to transform the ENU coordinates into ECEF and then calculate the heading?
Any help would be much appreciated.
