The iMet-54 research radiosonde offers all of the features of standard radiosondes plus an additional external data interface.
This external interface allows third party intelligent sensors and research equipment (e.g. ECC ozonesondes) to interface to the radiosonde.
Data is transferred using an XData protocol, this data is then packaged together with the standard iMet-54 telemetry data, and transmitted to the ground receiver system every second. The iMet54 research radiosonde offers a XData capacity of up to 316 bytes, which is over 6 times larger than the current typical industry offerings (50 bytes).
The iMet-54 also supports the extended XData1 protocol which allows individual packet sizes in excess of 256 bytes to be received from attached instrumentation.
Reception and processing by the ground system and D-Met software offers a range of output formats for analysis and further processing of the research data.
