Radar Health

The data protocol used to distribute real time radar data to network clients from Colossus based systems includes the definition of messages to convey radar health. These health messages are presented by the radar as a Byte array representing a serialised Protocol Buffer message. The required protobuf message files can be downloaded from

It is very strongly suggested that third party applications and systems consume the published radar health messages, with continuous verification that the radar is reporting healthy status against each of the monitored attributes.

The text below summarises the whole content of one health message.
