This is done by setting VersaSync System Time times- cale. The options are UTC, TAI and GPS. Typically, UTC is used for network syn- chronization.

    UTC and GPS is 18 seconds. 2.8.9.7 NTP Reference Configuration VersaSync's NTP Service needs to be setup such that it utilizes the time source ("input ref- erence") you want it to use. There are two options for an NTP Server to derive its time from: a.
  • Page 120 Note: Internet Time Servers should be configured as NTP Servers and not as NTP Peers. If VersaSync has no valid Timing System Reference, NTP Server or NTP Peers, the NTP Stratum value is automatically downgraded to Stratum 15. This ensures that its NTP cli- ents will no longer use this VersaSync unit as a time reference.

    Configuring "NTP Stratum Synchronization" NTP Stratum Synchronization refers to the concept of using a different NTP Server or Peer as your primary reference (instead of e.g., GNSS). This will make the VersaSync you are configuring a Stratum 2 server, since the other server is Stratum 1.
  • Page 122 If VersaSync is configured to obtain time from other NTP Servers at the same Stratum level (i.e., NTP Peers) but is currently using a different input reference as its selected ref- erence, VersaSync will report to the network (via the NTP time stamps) that it is a Stratum 1 time server.

In this rare use case the 1PPS is NOT aligned to any standard, therefore the time may drift, and must be considered untraceable.

Delete Position command deletes the GNSS antenna position data that is stored in the non-volatile memory of the GNSS receiver.
  • Page 201 VersaSync system is physically moved, and it did not self-initiate a new survey automatically. Note that neglecting to delete the old position data and discover the new position data will cause VersaSync not to go into synchronization state.

    In some cases, setting the position manually may also help to reduce the amount of time needed for the initial position "fix", i.e. for VersaSync to synchronize with the satellites in view.
  • Page 203 (both in decimal degrees), and altitude (in meters [WGS 84]) of your GNSS antenna, VersaSync can use this data during the satellite tracking/adjustment process, which typically leads to a quicker "fix". It is recommended to enter the position as accurately as possible.

    3.3.3.10 GNSS Constellations VersaSync allows you to select which GNSS constellations can be tracked. For example, you can determine if you want GLONASS satellites to be tracked (besides GPS). Selecting GNSS Constellations Your VersaSync is capable of tracking multiple GNSS constellations simultaneously.

QZSS is not considered a standalone constellation and while VersaSync allows you to enable QZSS by itself, it is recommended to use it in combination with GPS.

During this time period, VersaSync will be useable by its NTP cli- ents (or other consumers) after GNSS reception has been lost. The length of time is really based on the type of oscillator installed in a unit, and what the typical accuracy requirements are for the NTP clients.
  • Page 210 The chart below provides typical stability performance for the oscillator types that can be found in VersaSync units. These numbers are based on the oscillator being locked to a ref- erence for two weeks, but then loses GPS reception for an extended period of time, while the ambient temperature remains stable.

  • Page 342: Irig Standards And Specifications

    5.4.1 About the IRIG Output Resolution The IRIG output signals are generated from VersaSync's System Time, which can be synced to one or more external input references (such as GPS, IRIG, PTP, etc). The accur- acy of the System time to true UTC time is dependent upon what the selected external ref- erence is (with GPS typically being the most accurate reference for the system to sync with).

  • Page 343: Irig Carrier Frequencies

    IRIG AM synchronization of a device to its IRIG source is typically measured in the tens of microseconds, while synchronization using a IRIG DCLS signal can typically provide around 100 nanoseconds or so (plus the cable delays between VersaSync and the other device, as well as the processing delays of the other system itself).
