The scanning time for each scan frequency depends on the number of the selected frequencies (30
sec / N, N = number of frequencies).
This total time changes to 45 seconds after the first reception of the COSPAS-SARSAT pulse, which
enables the efficient scanning of the selected frequencies without missing the next COSPAS-SARSAT
pulses.
Figure 53. Example: Timing SAR scan, if only COSPAS-SARSAT frequency is detected.
If any of the selected emergency frequencies is detected, the scan algorithm will stay on this
frequency (releasing the alarm, if this setting is activated under scan settings) until the 45-seconds-
time elapses.
Figure 54. Example: Timing SAR scan, if no CP-SS pulse but a signal on an emergency frequency is
detected.
The algorithm returns back to the scanning of the main COSPAS-SARSAT frequency.
