Abstract: A system (100) comprising: a first unit (104) and one or more second units (104). The first unit (102) comprises: a timing reference (114) configured to provide a master-timing-reference-signal; a master time block configured to provide a master-time-signal (117) for the first unit (102) based on the master-timing-reference-signal; and a first interface (122) configured to: receive timestamped-processed-second-RF-signals from the one or more second units (104); and provide a first-unit-timing-signal (262) to the one or more second units (104) based on the master-time-signal. The one or more second units (104) each comprise: a slave time block (141) configured to: determine a slave-time-signal (142) for the second unit (104) based on the master-timing-reference-signal; determine one or more second-timing-values based on the slave-time-signal; determine an adjustment-time based on the first-unit-timing-signal received from the first unit (102) and the second-timing-values; and adjust the slave-time-signal based on the adjustment-time.
