ENHANCED DELIVERY OF GNSS CORRECTION DATA THROUGH RESTRICTED NETWORKS

摘要

Disclosed in some examples are methods, systems and machine readable mediums to efficiently stream data across restricted networks. In some examples, this streamed data may be sent more efficiently using lower overhead protocols such as UDP. In order to bypass the aforementioned limitations on these lower overhead protocols, the client may send a periodic update message to the server. This update message maintains the openings in the network firewalls and updates the server on the client's status. This update message may be sent much less frequently than a typical TCP acknowledgement, and the lower overhead protocol may be a protocol that does not retransmit lost or corrupted packets—thereby eliminating unnecessary overhead. In some examples this streamed data may be GNSS correction data. In some examples, the client may be behind one or more network firewalls.

主权项

1. A method of sending GNSS correction data to an agricultural implement, the method comprising:
using one or more computer processors to perform the operations of:
receiving a request over a network from the agricultural implement for the GNSS correction data, the agricultural implement located behind a firewall;retrieving authentication information for the agricultural implement in a data store;authenticating with a Global Navigation Satellite System (GNSS) correction source using the authentication information;requesting from the GNSS correction source the GNSS correction data;receiving a periodic message from the agricultural implement;responsive to receiving the periodic message from the agricultural implement, updating an Internet protocol (IP) address associated with the client device;receiving the GNSS correction data from the GNSS correction streaming source; andresponsive to receiving the correction data, forwarding the GNSS correction data to the agricultural implement using the IP address associated with the agricultural implement.
