This feature allows users to access StarFire corrections over the Internet, giving them access to the same reliable five centimeter global positioning accuracy without the need for a base station. Users are now also able to access StarFire corrections even in those situations when satellite delivery might be unavailable, such as deep urban canyons or very high latitude locations. Furthermore, the automatic failover capabilities in our StarFire enabled products allow the user to switch seamlessly from satellite to internet delivery of StarFire service and thereby maintain the maximum possible uptime. Not available on Sapphire-integrated systems which do not support an IP interface with Ntrip 2.0 (or later) protocol) SF-3040 requires software development by 3rd party SF-3040 in a LAND-PAK System requires either NavCom FieldGenius v6.0.3.1 or later, or NavCom SurvCE software (available in early 2013 with this specific feature) How it works: The receiver acts as an Ntrip client and initiates an Ntrip session including automatic authentication (no user parameters required). Requires the unit be licensed for StarFire operation Requires the unit to be optioned for StarFire over IP and StarFire Enabled Ntrip mountpoint and IP address is only provided to customers who are activated for this service. This information is provided at the time the software option is provided to the customer or from Customer Support NavCom FieldGenius and NavCom SurvCE are preconfigured to connect to the correct IP address The method that the GNSS receiver is connected to the internet is the customer’s responsibility. The connection can be made through a 3G modem, VSAT, Iridium, direct connection to the internet, etc. The connection can be made using StarUtil 3000 and the command line interface (Input Terminal). An Application Note is available to detail the mechanics of making the connection. Data management Packet size is currently at 787Bytes max with GPS and GLONASS corrections The service is offered with three different delivery modes to help customers manage their data costs: 1-second (streaming); 15-seconds; 60-seconds Packet size for different rates are the same size Convergence time and accuracy is the same for all delivery rates, whether over the air or via IP How do I get StarFire Over IP? StarFire Over IP Licensing Receiver needs StarFire over IP and StarFire Enable options Standard receiver StarFire license authenticates both services
