Status LEDs
The Z-Max GPS Receiver Module front panel has four status LEDs located at the top
of the front panel (Figure 2.3). The 3-color LEDs allow you to quickly monitor several
receiver functions at a glance. From left to right, the four LEDs are RTK SOLUTION,
COMMUNICATION, DATA LOG, and SV/Power. Each LED is described below.
RTK SOLUTION LED
The RTK SOLUTION LED is used to show the RTK solution status. This LED is
only operational when the receiver is configured as an RTK rover.
During RTK rover operation, if the LED is blinking green then the carrier phase
ambiguities have been resolved (or fixed) and the resulting solutions have
centimeter-level accuracy. This is more commonly referred to as a "fixed"
solution. If the LED is blinking orange, then the ambiguities are not resolved (or
floating). This is commonly referred to as a "float" solution. Accuracy of a float
solution can range between 10 cm and a few meters depending on the
operational scenario. If the LED is blinking red, then the receiver is not computing
RTK positions and indicates a problem in the RTK setup or configuration. The
LED blinks at the frequency of the solution output.
COMMUNICATION LED
The COMMUNICATION LED indicates when real-time data transmitted from the
base receiver has been received by the rover. It covers all data links including the
Communication Module data links and external wireless modems. If the light is
blinking GREEN, then the real-time data being transmitted by the base station
has been received by the rover and is useable. If the light is blinking RED, then
the real-time data being received by the rover is detected but not usable for some
reason. Regardless of color, the LED will blink at the frequency of data reception.
If the LED does not blink at all, no data is being received by the rover.
