Ranging Transaction Messages

3.6.6.

3.6.6.1. Range Measurement

The ranging transaction response message for a range measurement request contains:

Two-way « Distance » values, in nanoseconds (after ambiguity solving. Not significant for the
INMARSAT and LMCO standards,

The ambiguity solving quality factor (not significant for the INMARSAT and LMCO standards).
Then, for each tone and only in case of request for phase and time measurements:

Major tone phase-shift values (∆Φ
Correction »,

Minor tone phase-shift values (∆Φ
CORTEX CRT Quantum returns average phase-shift values, including Doppler compensation but
excluding « Spectrum Correction » and « Board Correction ». Not significant for the ESA code
standard.

Correction for spectrum offsets and on-board phase-delay (∆Φ
tone.
All phase values are expressed in degrees, with a resolution of 360°/2

3.6.6.2. Calibration Measurement

The ranging termination message for a calibration measurement request contains:

Two-way « Distance » values, in nanoseconds (after ambiguity solving. Not significant for the
INMARSAT and LMCO standards),

The ambiguity solving quality factor (not significant for the INMARSAT and LMCO standards),
Then, for each tone and only in case of request for phase and time measurements:

Major tone phase-shift values (∆Φ
Correction »,

Minor tone phase-shift values (∆Φ
CRT Quantum returns average phase-shift values, including Doppler compensation but excluding «
Spectrum Correction » and « Ground Correction ». Not significant for the ESA code standard.

Correction for spectrum offsets and ground phase-delay (∆Φ
tone.
All phase values are expressed in degrees, with a resolution of 360°/2
