Abstract

In some implementations, a device may receive, via a universal serial bus (USB) interface, configuration information and a supply of power from a network device. The device may receive, via an antenna that is external to the device, a first signal indicating timing information. The device may generate, based on the first signal, a second signal and a third signal, wherein the second signal comprises a one pulse per second signal and the third signal comprises a ten-megahertz signal. The device may provide, to the network device, the second signal and the third signal. The device may receive, via an input port, a clock signal to provide an extended holdover functionality to the network device.

First claim

What is claimed is:

1 . A method, comprising:
providing, by a first device and via a universal serial bus (USB) interface, configuration information and a supply of power to a second device; obtaining, by the first device and from the second device, a first signal and a second signal,
wherein the first signal and the second signal are generated based on a third signal obtained via an antenna, and
wherein the first signal comprises a first frequency signal and the second signal comprises a second frequency signal; and
providing, by the first device, a fourth signal, wherein the fourth signal comprises a clock signal that enables the second device to perform an extended holdover functionality to the first device.

2 . The method of claim 1 , wherein the configuration information indicates one or more of:
a length of a cable connecting a dongle and the first device, a length of a cable connecting a dongle and the antenna, or data associated with modifying a firmware of the first device.

3 . The method of claim 1 , wherein the second device is a global navigation satellite system (GNSS) receiver.

4 . The method of claim 1 , wherein the third signal is a global navigation satellite system (GNSS) signal.

5 . The method of claim 1 , further comprising:
obtaining a one pulse per second signal.

6 . The method of claim 1 , wherein the second signal enables the first device to track phase or frequency.

7 . The method of claim 1 , further comprising:
performing the extended holdover functionality based on a quality of the third signal.

8 . A first device, comprising:
one or more memories; and one or more processors to:
provide, via a universal serial bus (USB) interface, configuration information and a supply of power to a second device;
obtain, from the second device, a first signal and a second signal,
wherein the first signal and the second signal are generated based on a third signal obtained via an antenna, and
wherein the first signal comprises a first frequency signal and the second signal comprises a second frequency signal; and

provide a fourth signal, wherein the fourth signal comprises a clock signal that enables the second device to perform an extended holdover functionality to the first device.

9 . The first device of claim 8 , wherein the configuration information indicates one or more of:
a length of a cable connecting a dongle and the first device, a length of a cable connecting a dongle and the antenna, or data associated with modifying a firmware of the first device.

10 . The first device of claim 8 , wherein the second device is a global navigation satellite system (GNSS) receiver.

11 . The first device of claim 8 , wherein the third signal is a global navigation satellite system (GNSS) signal.

12 . The first device of claim 8 , wherein the one or more processors are further to:
obtain a one pulse per second signal.

13 . The first device of claim 8 , wherein the second signal enables the first device to track phase or frequency.

14 . The first device of claim 8 , wherein the one or more processors are further to:
perform the extended holdover functionality based on a quality of the third signal.

15 . A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a first device, cause the first device to:
provide, via a universal serial bus (USB) interface, configuration information and a supply of power to a second device;
obtain, from the second device, a first signal and a second signal,
wherein the first signal and the second signal are generated based on a third signal obtained via an antenna, and
wherein the first signal comprises a first frequency signal and the second signal comprises a second frequency signal; and

provide a fourth signal, wherein the fourth signal comprises a clock signal that enables the second device to perform an extended holdover functionality to the first device.

16 . The non-transitory computer-readable medium of claim 15 , wherein the configuration information indicates one or more of:
a length of a cable connecting a dongle and the first device, a length of a cable connecting a dongle and the antenna, or data associated with modifying a firmware of the first device.

17 . The non-transitory computer-readable medium of claim 15 , wherein the second device is a global navigation satellite system (GNSS) receiver.

18 . The non-transitory computer-readable medium of claim 15 , wherein the third signal is a global navigation satellite system (GNSS) signal.

19 . The non-transitory computer-readable medium of claim 15 , wherein the second signal enables the first device to track phase or frequency.

20 . The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions further cause the first device to:
perform the extended holdover functionality based on a quality of the third signal.
