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.
