SF-2050 User Guide – Rev. G

SF-2050 automatically configures to use the most
suitable correction source available and changes as
the survey dictates (this feature can be overridden).

Extend™

1

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 up to 5Hz
in the standard configuration. An optional upgrade
allows 10, 25, and 50Hz raw measurement data via
either 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-2050 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
