4.6 Performing a Receiver Cold Start
A Warm Start is performed by most GNSS receivers after a power reset. The data (ephemeris,
almanac) is remembered to aid in obtaining the satellites during next power-up.
To perform a Cold Start , initiate a cold start command to the receiver, or clear its memory by
using other means intended for this purpose. Resetting the power does not perform a cold start
by design.
Note: ALWAYS force a Cold Start , or a full reset of a receiver after it had been
used with generated signals!
Without a Cold Start:
The receiver will reject the generated signals as invalid.
The receiver may not find the generated satellites.
The receiver may fail to navigate or behave poorly.
4.7 Creating a One-Line Trajectory
As the GSG unit uses the heading and speed information of the RMC sentences, only one
NMEA sentence is actually required to describe a simple, continuous movement.
For example, the following one-line trajectory specifies a continuous north-bound trajectory (as
the
heading field is set to 0.0 degrees) at a speed of 77 knots:
