Novatel 01018300 User Manual

This section contains information on the additional features of the SMART-AG, which may affect the 
overall design of your receiver system.

An input (MKI) and output (PPS) strobe provide status and synchronization signals. PPS is a 3.3V 
CMOS output; MKI is a 5V logic tolerant input. 

Pin-out information can also be found on Page 61.

LED indicators on the SMART-AG provide the status of the receiver. They represent these categories:

• Position Status
• Position Type
• Power

Table 3 shows the meaning of the LED states in the expected sequence after power is applied. 

Flashing means that the LED is turning on and off at a 1 Hz rate - 0.5 seconds on and 0.5 seconds off.

Debugging:

•

If the power is on but the yellow LED doesn’t flash within one minute, then no satellites are 
tracking. There may be excessive blockage or the unit may be defective. Make sure the unit has 
an unobstructed view of the sky. Try power cycling the unit.

•

If the yellow LED is flashing but doesn’t progress to solid yellow within one minute, then 
insufficient satellites are tracking or the signal quality is poor and ephemeris data can’t be 
received. Normally, four satellites are sufficient for a valid position as long as they are widely
