FIGURE E-3. KSC electric field change and CS110 slow antenna data
The KSC electric field mill and the CS110 were not precisely synced
accounting for some of the differences in the data shown in the above graph.
Since that time, the CS110 has been improved and now has the ability to sync to
within ±10 µs of the GPS signal’s PPS pulse. The resolution of accuracy for the
clock set is 10 microseconds if the internal CR1000 datalogger has a hardware
revision number greater than 007 (RevBoard field in the datalogger's Status
table).
