Abstract

A microservice node can include a network real-time kinematics (RTK) device to receive raw satellite data associated with a physical reference station via a first message in a first message queue, to receive static virtual location data associated with a static virtual reference station (VRS) agent, to generate corrections data for the static VRS agent based on the raw satellite data and the static virtual location data, and to transmit the corrections data to the static VRS agent. The microservice node can include the static VRS agent to publish the corrections data in a second message in a second message queue. The microservice node can include an adapter device to determine that the client device is located within a geographic area associated with the static VRS agent and to transmit the corrections data from the second message queue to the client device.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a network real-time kinematics (RTK) device, raw satellite data via a first message in a first message queue,
wherein the raw satellite data is associated with a physical reference station;

receiving, by the network RTK device and based on receiving the raw satellite data, static virtual location data associated with a static virtual reference station (VRS) agent among a plurality of static VRS agents associated with the network RTK device;
generating, by the network RTK device, corrections data for the static VRS agent based on:
the raw satellite data associated with the physical reference station, and
the static virtual location data associated with the static VRS agent;

transmitting, by the network RTK device, the corrections data to the static VRS agent;
publishing, by the static VRS agent, the corrections data in a second message in a second message queue,
wherein the first message queue and the second message queue are provided by a message queue device that is included in a microservice node that includes the RTK device;

determining, by an adapter device and based on physical location data received from a client device, that the client device is located within a geographic area associated with the static VRS agent; and
transmitting, by the adapter device and based on determining that the client device is located within the geographic area associated with the static VRS agent, the corrections data from the second message queue to the client device.

2. The method of claim 1 , further comprising:
receiving respective physical location data associated with a plurality of client devices that include the client device;
wherein determining that the client device is located within the geographic area associated with the static VRS agent comprises:
determining, based on the respective physical location data, that the plurality of client devices is located within the geographic area associated with the static VRS agent; and

wherein transmitting the corrections data from the second message queue to the client device comprises:
transmitting the corrections data from the second message queue to the plurality of client devices.

3. The method of claim 1 , wherein the adapter device comprises at least one of:
a Kafka consumer function, or
a corrections as a service (CaaS) function.

4. The method of claim 1 , further comprising:
subscribing the client device to the second message queue based on determining that the client device is located within the geographic area associated with the static VRS agent; and
wherein transmitting the corrections data from the second message queue to the client device comprises:
transmitting the corrections data from the second message queue to the client device based on determining that the second message was published to the second message queue.

5. The method of claim 1 , wherein transmitting the corrections data to the client device comprises:
transmitting the corrections data to the client device via a base station and a serving center device.

6. The method of claim 5 , wherein transmitting the corrections data to the client device via the base station and the serving center device comprises:
determining that the base station serves the geographic area associated with the static VRS agent; and
transmitting the corrections data to the client device based on determining that the base station serves the geographic area associated with the static VRS agent.

7. The method of claim 6 , wherein the serving center device comprises at least one of:
a broadcast multicast service center (BMSC) device, or
an evolved serving mobile location center (E-SMLC) device.

8. A microservice node, comprising:
a network real-time kinematics (RTK) device, to:
receive raw satellite data via a first message in a first message queue,
wherein the raw satellite data is associated with a physical reference station;

receive, based on receiving the raw satellite data, static virtual location data associated with a static virtual reference station (VRS) agent among a plurality of static VRS agents associated with the network RTK device;
generate corrections data for the static VRS agent based on:
the raw satellite data associated with the physical reference station, and
the static virtual location data associated with the static VRS agent; and

transmit the corrections data to the static VRS agent;

a static VRS device, to:
publish the corrections data in a second message in a second message queue;

a message queue device, to:
provide the first message queue and the second message queue; and

an adapter device, to:
determine, based on physical location data received from a client device, that the client device is located within a geographic area associated with the static VRS agent; and
transmit, based on determining that the client device is located within the geographic area associated with the static VRS agent, the corrections data from the second message queue to the client device.

9. The microservice node of claim 8 , wherein the adapter device is further to:
receive respective physical location data associated with a plurality of client devices that include the client device;
wherein the adapter device, when determining that the client device is located within the geographic area associated with the static VRS agent, is to:
determine, based on the respective physical location data, that the plurality of client devices is located within the geographic area associated with the static VRS agent; and

wherein the adapter device, when transmitting the corrections data from the second message queue to the client device, is to:
transmit the corrections data from the second message queue to the plurality of client devices.

10. The microservice node of claim 8 , wherein the adapter device comprises at least one of:
a Kafka consumer function, or
a corrections as a service (CaaS) function.

11. The microservice node of claim 8 , wherein the adapter device is further to:
subscribe the client device to the second message queue based on determining that the client device is located within the geographic area associated with the static VRS agent; and
wherein the adapter device, when transmitting the corrections data from the second message queue to the client device, is to:
