System Overview
GNSS Sensor System
The SF-3050 Global Navigation Satellite Systems (GNSS) sensor
delivers superior accuracy to the precise positioning community.
This unique receiver is designed with a robust and long-term
performance upgrade path to meet changing needs via software
upgrades. Increased functionality does not typically require the
costly purchase of additional hardware.
The SF-3050 software-enabled features, bundled or purchased individually, cover a wide
variety of applications.
The SF-3050 is uniquely suited for real-time applications in areas such as surveying,
machine control, precise positioning, and construction. The sensor delivers the required
millimeter measurement precision and fast update rates at low data latency. Depending
on the software bundle, the SF-3050 provides flexibility to be configured as a base station
or as a rover.
Superior interference suppression (both in-band & out-band), multipath mitigation, and
measurement accuracy are only a few of the sensor’s technological advances. The SF-
3050 GNSS engine incorporates several patented innovations advancing the existing
GNSS technology to the next generation. The receiver provides near optimal GPS P-code
recovery, providing a significant signal-to-noise ratio advantage over competing
technologies, among other benefits.
There are four software bundles: the SF-3050A, SF-3050G, SF-3050S, and SF-3050M.
Depending upon the bundle, this receiver provides, but is not limited to:
 NavCom’s StarFire 1
Network: A worldwide Satellite Based Augmentation System
(SBAS) for decimeter level position accuracy (post-convergence period). Refer to
Appendix C for detailed information.

 RTK: This unique receiver is designed to integrate easily into Real-Time Kinematic
(RTK), field data verification, topographical surveys, and a wide variety of surveying
applications. The system resolves ambiguities at startup or on satellite reacquisition
typically within 2 seconds. The
SF-3050 delivers centimeter level position accuracy via external RTK

formats.
The receiver is capable of NCT RTK/UltraRTK™, RTCM 2.3 and 3.1 (code
and phase), Network RTK, and CMR/CMR+ DGPS operating methods. The operating
software is also capable of supporting an external radio modem.
