Description Common Settings

The following two lists provide an overview of the common settings for single frequency and double frequency processing as provided in the examples and demo.

Single Frequency Solution:

  • Only using the P-code measurements and their linear combinations.
  • Using precise ephemeris (.SP3) files and CODE 5 second interval clock (.CLK_05S) files as input.
  • Navigation file (.YYn) used for the Klobuchar correction parameters.
  • Elevation mask set to 10 degrees.
  • Solution computed every 5 seconds (no clock interpolation needed).
  • Discarding eclipsed satellites (less accurate orbit information).
  • L1-C1 difference used for cycle slip detection.
  • Apply satellite clock offset correction (CODE .CLK_05S files).
  • Consider movement of satellite during signal flight (compute satellite position at toime of transmission).
  • Consider Earth rotation during signal flight.
  • Apply Satellite mass to antenna phase centre correction (SP3 orbit files are referenced to the satellite mass centre and not to the antenna phase centre) from Antex file.
  • Apply receiver antenna phase centre correction, from Antex file.
  • Apply relativistic clock correction (periodical part due to orbit excentricity).
  • Apply relativistic path range correction.
  • Apply ionospheric correction using Klobuchar.
  • Apply tropopsheric correction using UNB-3 and Neill.
  • Apply Phase wind up correction (relative rotation between receiver and satellite).
  • Solid Tides correction
  • Orbit polynomial interpolation degree: 10
  • Clock polynomial interpolation degree: 1
  • Estimating Troposhere in Kalman filter disabled.

Dual Frequency Solution:

  • Only using the P-code measurements and their linear combinations (Iono free pseudo range combination and carrier phase combination).
  • Using precise ephemeris (.SP3) files and CODE 5 second interval clock (.CLK_05S) files as input.
  • Elevation mask set to 10 degrees.
  • Solution computed every 5 seconds (no clock interpolation needed).
  • Discarding eclipsed satellites (less accurate orbit information).
  • Geometry Free Phase and Melbourne-Wubbena linear combinations used for cycle slip detection.
  • Apply satellite clock offset correction (CODE .CLK_05S files).
  • Consider movement of satellites during signal flight (compute satellite position at toime of transmission).
  • Consider Earth rotation during signal flight.
  • Apply Satellite mass to antenna phase centre correction (SP3 orbit files are referenced to the satellite mass centre and not to the antenna phase centre) from Antex file.
  • Apply receiver antenna phase centre correction, from Antex file.
  • Apply relativistic clock correction (periodical part due to orbit excentricity).
  • Apply relativistic path range correction.
  • Apply ionospheric correction using Klobuchar.
  • Apply tropopsheric correction using UNB-3 and Neill.
