RTK Extend™ enables continuous real-RTK/RTK
level positioning accuracy during radio
communication outages by utilizing NavCom’s global
StarFire™ corrections.
Traditionally, when an RTK rover loses
communication with the base station, it is unable to
continue to provide centimeter position updates for
more than a few seconds, resulting in user down-time
and reduced productivity. With RTK Extend™, a
NavCom StarFire™ receiver operating in RTK mode,
can transition to RTK Extend™ mode and maintain
centimeter level positioning during communication
loss for up to 15 minutes. RTK Extend™ allows more
efficient and uninterrupted work, enabling focused
concentration on the work rather than the tools.
„ Data
Sampling
GPS L1 and L2 raw measurement data is output up
to 5Hz on either data port in the standard
configuration. An optional upgrade allows 10, 25, and
50Hz raw measurement data via one of the two serial
ports.
The PVT (Position, Velocity, & Time) data is output at
up to 5 Hz in the standard configuration. An optional
upgrade allows 10 and 25Hz position updates for
highly dynamic applications.
„ GPS
Performance
The SF-2040 utilizes NavCom’s NCT-2100 GPS
engine, which incorporates several patented
innovations. The engine’s industry leading receiver
sensitivity provides more than 50% signal to noise
ratio advantage over competing technologies. This
results in improved real time positioning, proven
through independent tests, when facing various
