Position reports can be transmitted in a number of possible formats. When the format is disabled or the Address or
Port fields are blank, no report is sent.

GPS "sentences" are collected the from embedded GPS receiver in the Fusion 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.
Local delivery
The Fusion router will produce a report each second and send it to any connected TCP clients and to the specified UDP
hosts. IMPORTANT: Local reports should only be delivered to addresses reachable through the local LAN or WiFi ports.
Sending reports once per second or faster over the cellular network could result in a congested cellular network and/or
extremely large network usage charges.
