DGPS OPERATION
This chapter describes operating the LH 665 in conjunction with DGPS for yield
logging, field boundary measurement and application rate control.
There are many ways to show DGPS information in the LH 665 and they are
described here, as these are common for all operating modes.
DGPS STATUS ON THE SCREEN
The current DGPS status is shown in the top right corner of the display, if logging
positional data has been selected. The following describes various different status
situations:
--
Shows that logging has been selected, but that no data is being
transferred to the data card, e.g. the machine is stopped.
--О О О О Shows that logging has been selected but that no positional signals
are being received either from satellites or the differential transmitter.
DGО О О О Shows that the LH 665 is receiving a GPS and a differential signal.
The GPS receiver has a signal from at least 4 satellites (3
dimensional). The arrow indicates that the data is being logged to a
data card.
DG As above, but the data is not being logged to a data card.
GО О О О Shows that the LH 665 is receiving a GPS signal, but no differential
signal. The GPS receiver is receiving signals from at least 4 satellites
(3 dimensional). The arrow indicates that data is being logged to a
data card.
DgО О О О shows that the LH 665 is receiving a GPS and a differential signal. The
GPS receiver is receiving signals from 3 satellites (2 dimensional). The
arrow indicates that data is being logged to a data card.
