14.2 mojoXact Plus GPS Receiver Technical Data
Performance Performance values quoted are typical values. Performance specifications are subject
to GPS system characteristics, US DoD operational degradation, ionospheric and
tropospheric conditions, satellite geometry, multipath effects, and the presence of
intentional and unintentional interference sources.
