Product description
The LEA-4T supports precision GPS timing and raw measure-
ment data for demanding positioning applications. It features
a Time Mode function whereby the GPS receiver assumes a
stationary 3D position, whether programmed manually or de-
termined by an initial self-survey. Stationary operation enables
GPS timing with only one visible satellite and eliminates timing
errors which otherwise result from positioning errors. The
accuracy of the time pulse is as good as 50 ns, synchronized to
GPS or UTC time. An accuracy of 15 ns is achievable by using
the quantization error information to compensate the granu-
larity of the time pulse. The built-in 2-channel time mark and
counter unit provides precise time measurement of external
interrupt signals.
The LEA-4T also supports raw measurement data (carrier
phase with half-cycle ambiguity resolved, code phase and
Doppler measurements), which can be used in external
applications that offer precision positioning, real-time kine-
matics (RTK) and attitude sensing.
