VIAVI TestCenter: Some important points on chassis Sync with GPS

1. Following power-up and initialization, the receiver requires at least four concurrent “good current” satellites to resolve its current position. 2. Once the GPS receiver is a valid time reference, it requires at least one “good current” satellite to remain a valid time reference. 3. When the GPS goes back in sync with respect to the satellite, VIAVI TestCenter will see it as a valid sync source and switch back to the GPS.
