Calculate Height of ARP and APC

Input Data

Measured height (C) = 0.0000 meter(s)
Calculated ARP height = 0.0000 meter(s)
Calculated APC height = 0.0000 meter(s)

Usage Notes

  • Measured height is the slant distance from the survey mark to Slant Height Measurement (SHM). One should refer to the product specification for the assigned SHM in each antenna.
  • ANTCALC V1.0 calculates two antenna heights, i.e., Antenna Reference Point (ARP) and Antenna Phase Centre (APC). 
  • When using a scientific GNSS data processing (e.g., GAMIT and Bernese), it is common to introduce ARP height as antenna calibrations are often introduced in data processing.
  • If there is no information regarding the antenna calibration, APC height should be used instead.

The naming of antennas and all variables are obtained from the National Geodetic Survey (NGS) https://geodesy.noaa.gov/ANTCAL/#
