  • Page 19: Reference

    Reference The Reference tab consists of three sections, the Reference, Reference Status, and Reference Settings. This tab allows you to modify the reference for the Network Time Adapter. Please note that while the Network Time Adapter is acquiring time from the references the Valid Time LED indicator will be extinguished.

  • Page 20: Reference

    4.4.1 Reference The Reference consists of two fields, the Select reference and Reference Stable. The Select reference allows the user to select one of the three references to acquire time from. The three references used by the system are NTP Time Server, Serial Port Input, and GPS (model NTA- 100GM only).

  • Page 21: Reference Status

    The GPS reference uses a GPS receiver to synchronize the internal clocks. The stratum level for this reference is 1. To use the GPS reference, the GPS option must be installed. The Reference Stable may be either ‘TRUE’ or ‘FALSE’. It is ‘TRUE’ when the Network Time Adapter has acquired the time from a reference.

  • Page 22: Open Satellite Status

    4.4.2.1 Open Satellite Status The system provides a comprehensive view of the GPS receiver. A typical GPS receiver screen is displayed below. The upper section of the screen displays different tracked satellites and their signal strengths. The typical GPS Signal Strength for a satellite that is overhead and has an unobstructed view is between 40 and 50.

  • Page 23: Gps Settings

    4.4.2.2 GPS Settings The figure below is displayed when the user clicks on the GPS Settings link. The GPS Settings screen consists of two sections, the Settings and Version. This screen allows the user to select a position mode, set a position, cold start, set the GPS lock criteria, and view the version number of the GPS receiver.
  • Page 24 4.4.2.2.1 Settings The Settings consist of six fields, the Position Mode, Enable mobile mode, Position, Cold Start, Tracking at least X satellites, and using T-RAIM.

Please note that the input format is DD.DDDDDD. The latitude and longitude are in degrees and the altitude is measured in meters.

  • Page 26: Reference Settings

    4.4.3 Reference Settings The Reference Settings consists of six fields, a NTP Query Interval and five NTP Server Address Pool entries. The NTP Query Interval is a number (in seconds) entered by the user. The NTP Query Interval will be invalid for the first 300 seconds because the NTP client will be sampling the time once every second and adjusting the internal clocks in the NTP servers using the internal Proportional Integral algorithm.
