About Short Burst Data (SBD)

SBD is a bandwidth-limited messaging system, capable of transmitting packets of up to 340 bytes, and receiving packets of 270 bytes.

SBD is suitable for applications which need to regularly send or receive small amounts of information - typically these would include tracking, telemetry, system control and monitoring applications.

It is not suitable if very low latency is required, or if the data to be transmitted is larger than a few thousand bytes. Sending images, or GRIB files, is usually not sensible.

With a good view of the sky, it is possible to send/receive approximately once every 10 seconds.
