SMART2 Operation
Any of the COM port prompts indicate that the receiver is ready and waiting for command input.
The screen may display other port names for other port types.
1. Output from receiver self-tests may take some time. On startup, the receiver is set to
log the RXSTATUSEVENTA log ONNEW on all ports. See RXSTATUSEVENT Log on page 40
for more details.
2. If NovAtel Connect is unable to locate the receiver, use a different COM port to com-
municate with the receiver. When communication has been established, issue a FRESET
STANDARD command. The original communications port should be ready for use. See
the FRESET command for more information.
An example of a response to an input LOG command:
[COM2] LOG COM1 BESTPOS ONTIME 1
<OK
In this example, [COM2] is the port prompt.
This example illustrates command input to the base receiver's COM2 port that sets the position
of the base station receiver for differential operation.
If the command was accepted, the receiver responds with:
<OK
If a command is entered incorrectly, the receiver responds with:
<ERROR:Invalid Message ID
Ensure the computer does not sleep or hibernate during a logging session or data will be
lost.

ations. GLIDE produces a smooth position output tuned for applications where time relative
accuracy (pass-to-pass) is more important than absolute accuracy. Because of this, it is well
suited for agricultural applications.
Multipath signals tend to induce time varying biases and increase the measurement noise on the
L1/L2 pseudorange measurements. Carrier phase measurements are much less susceptible to
the effects of multipath. The GLIDE algorithm fuses the information from the L1 code and the L1
phase measurements into a Position Velocity Time (PVT) solution.
GLIDE includes settings for a dynamic mode, a static mode and an "auto" mode, where the fil-
tering parameters are automatically adjusted as vehicle velocity varies between stationary and
dynamic states.
3.3.1 Dual-Frequency GLIDE
NovAtel's dual-frequency GLIDE technology adds to the superior pass-to-pass performance
provided by single-frequency GLIDE. Dual-frequency GLIDE is ideal for agricultural and machine
guidance applications where relative positioning is critical. Using GLIDE significantly reduces the
variation in position errors to less than 1 cm from one epoch to the next. Dual-frequency GLIDE
improves the absolute accuracy of the GLIDE position and creates a robust solution resistant to
