Measurement Time-Tagging - Safran CORTEX CRT Quantum User Manual

Measurement Time-Tagging

3.6.5.
The time-tag in the ranging transaction response message corresponds to:

the first phase measurement performed on the first tone of the ranging sequence (INMARSAT and
LMCO standards),

the first « distance » calculation of the ranging message (ESA, ESA-like and USB tone standards,
ESA code standard).
Every measurement in the ranging transaction response message can be easily dated by simply adding to the
time-tag the appropriate number of time intervals separating two consecutive measurements.
