Any of three operational configurations is available in accordance with the used ADMA hardware version, the involved vehicle test and required accuracy of data: Stand-alone, ADMA with external speed signal and ADMA with (D)GNSS. The diagram below depicts these three configurations.
Note: The operational configuration involving ADMA with a (D)GNSS does not necessarily require an external speed signal. Such a signal proves especially useful in situations susceptible to GNSS failure.
