Please note that the station simply replies to the command with the data. In this example, the station was
asked for data via Iridium, so it replied via Iridium. If it had been asked via RS-232, it would have replied via
RS-232.
A note about timestamps in the repeat Tx data: The timestamps are the same as if the Tx were made at
the provided time, rather than indicating the true age of the data. This meas that the sensor data in the Tx
is exactly the same as that of the Tx made in real time (which is 2016/6/20 23:00:30 in the example
above). It is the caller's responsibility to handle the timestamps.
Why not have the timestamps indicate the true age of the data:
Unlike re-transmissions which are initiated by the logger, these repeat Tx data transmissions are
initiated by someone who knows the timestamps of the missing data.
Some systems will find it easier to integrate data that is in an unmodified format.
Most data formats (including SHEF and Pseudobinary B) do no support timestamps that indicate
very old data.
Note that append data is NOT provided in a repeat transmission!
The capture below illustrates the difference that the REPEAT option has on the TXFORM command. Note
that no date was issued with the REPEAT command, meaning it uses the current time as the time of Tx.
Note the lack of append data.

Available space is 2110 bytes
In that message, sensor data is 83 bytes
Worst case SENSOR data (excluding append) is 138 bytes (00:00:05 seconds)
Worst case available space is 2080 bytes
2 meas are active; 2 are marked for tx

Automatic Missing Data Retrieval
Cell and Iridium transmissions may be automatically retired. Please see Retransmissions below.
