SF-3050 User Guide – Rev B
 NCT
RTK/UltraRTK
The RTK/UltraRTK algorithm developed by NavCom
provides fast initialization and the NCT ultra compact
binary data format for RTK/UltraRTK ensures robust
data throughput.
The SF-3050 is capable of outputting or accepting
legacy 0x5B (RTK) or 0x5E (UltraRTK) binary
formats. Refer to the TRM for more details (see
Related Documents in the fore-matter).
 Positioning
Flexibility
The SF-3050 is capable of using WAAS, EGNOS,
MSAS, GAGAN (RTCA/DO-229D compliant) code
corrections via two internal Satellite Based
Augmentation System (SBAS) channels. The
SF-3050 automatically configures to use the most
suitable correction source available and changes as
the survey dictates (this feature can be overridden).
 RTK
Extend™
RTK Extend
1
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
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.
