The emergency Topnet Live subscriptions will be active for 90 days at a time and will support any brand of dual-frequency GNSS equipment that can use Topcon’s standard NTRIP correction message (RTCM 3.x). Topcon and its distributors will manage these subscriptions as a service for essential agencies to aid in the assessment of damages and start the rebuilding process.
“We’re headquartered in California, and we want to help take care of our home state in a time of crisis,” said Killpack. “We will offer these correction services free of charge through this emergency subscription service to anybody that needs them, regardless of who they work for, what kind of equipment they have, and for the next 90 days they can connect to our network to get the corrections they need to get their essential job done.”

About correction services: In order to provide precise positioning accuracy, a GNSS receiver needs to compensate for inaccuracies caused by satellite constellations, receiver hardware and atmospheric conditions. These inaccuracies can be calculated by a network of fixed reference stations that constantly receive GNSS data. This correction information is then broadcast to GNSS receivers as a service.
