GNSS Cable Length and Antenna Notes

This discussion relates to the topic of antennas and cabling that may be utilized in conjunction with a Studio Technologies, Inc. Model 5402 Dante Leader Clock with GNSS Synchronization.

We’ll begin by citing Google’s AI Overview of GNSS:

GNSS, or Global Navigation Satellite System, refers to any satellite constellation that provides global positioning, navigation, and timing services. It’s a technology that allows users to determine their location on Earth using signals from multiple satellites.

Supporting PTP v2 (AES67 and ST 2110) with the Model 5401A and the Model 5402

The Model 5401A Dante Leader Clock and the Model 5402 Dante Leader Clock with GNSS Synchronization were primarily designed for use in applications that utilize devices running “native” Dante. To support the timing needs of these devices Precision Time Protocol Version 1 (IEEE-1588-2002 or “PTP v1”) was implemented. The units’ PTP v1 implementation functions very well, including in redundant Dante applications. (Independent Ethernet networks connected to the Primary and Secondary Ethernet ports on the back panel of the Model 5401A and Model 5402 units.) Even in large installations with literally hundreds of Dante devices,
