GPS "sentences" are collected the from embedded GPS receiver in the Fusion LTE Router. These sentences are provided
into the above formats and are available to both local and remote delivery services. Two TCP ports are available for clients
to connect to and receive reports at the local or remote reporting rate. Each report from the TCP ports is terminated with
carriage-return/linefeed characters (CRLF). Up to two local UDP Hosts and three remote UDP Hosts may be specified.
Reports are sent as a datagram with no terminating CRLF.

Differential Correction
Differential Correction allows WAAS correction information to be used to improve accuracy of the GPS position
reports.
NOTE: WAAS correction applies to North America only. The WAAS satellites currently in service are 48 (Galaxy 15)
and 51 (Anik F1R). The previous WAAS satellites 35 and 47 were taken out of service on 2007/07/30. WAAS
improves the tracking accuracy of the GPS navigation system to approximately 10 feet.
