GPS Status Icon

The current source and status of DGPS signal is

displayed in the upper, left corner of the Home Screen.

Note: Touch the shield icon to display the GPS Status

screen. The standard GPS shield is displayed if the

Cruizer II console cannot determine the type of

corrections received.

The GPS Status Icon on the Home screen will display:

RTK Fixed and Float Modes

When using an RTK correction source with the internal dual frequency GPS

receiver, the GPS status indicator may be used to determine whether the

receiver is operating in RTK fixed or float modes. The RTK shield will display:

if the status of DGPS is O.K.

(flashing yellow/red) if DGPS is initializing or converging.

if an error or cautionary condition has been encountered.

if GPS is non-functional. Make sure the DGPS antenna cable

connections are secure and the antenna has a clear, 360° view of the

sky.

when the receiver has a full RTK position fix and is providing

sub-inch corrections.

Note: The GPS Health screen will display a value of 4 for the

differential mode when operating in RTK fixed mode.

when the receiver is operating in RTK float mode. This mode indicates

that the receiver is not able to provide a full RTK position lock due to

the distance from the base station, visibility of the sky, time of day or

interference around the base station location. In the float mode, the

receiver is still providing a coarse RTK correction signal, but

corrections may not provide sub-inch accuracy.

Note: The GPS Health screen will display a value of 5 for the

differential mode when operating in RTK float mode.
