Synchronization In Normal Operation

When the byteflightΒ  is started following sleep mode and approx. every 16 s during operation, the SIM transmits a "system time" telegram.

Due to the relatively low priority of the telegram, there is no assurance that the routing takes place immediately. This leads to a possible difference between the time in the SIM and the time in the satellites.

As the SIM knows the time of the transmission of the telegram, a correction is possible.

A second telegram "system time" with the correction value as part of the content is sent.

The correct system time is therefore the total of the values of the two system time telegrams. The satellites only adopt the system time when both system time telegrams have been received.
