3050G and SF-3050S. An optional upgrade allows 10, 25, 50, and 100Hz raw
measurement data via high speed ports.
For the SF-3050M, the raw measurement data is up to 25Hz in the standard
configuration, with the optional upgrade of 50 and 100Hz.
The PVT (Position, Velocity, & Time) data is output at up to 5Hz in the standard
configuration for the SF-3050G and SF-3050S. An optional upgrade allows 10, 25, 50,
and 100Hz position updates for highly dynamic applications.
For the SF-3050M, the PVT data is output at up to 25Hz in the standard configuration,
with the optional upgrade of 50 and 100Hz.
 Internal Memory
See the Sapphire Technical Reference Manual and the StarUtil 3000 User Guide for
detailed instructions on utilizing the SF-3050 internal memory flash drive.
 Control of Power Consumption
Power consumption may be immediately reduced on the SF-3050 by disabling signals, as
necessary, using the [TRACKINGMODE] command. Refer to the Sapphire Technical
Reference Manual for instructions on using this command.
 Continuously Operating Reference Station (CORS) Support
When optioned as an RTK Base Station, the SF-3050 is capable of computing and
outputting RTK message streams in multiple formats and raw satellite measurement data
for post-processing simultaneously. All message formats can be output on one of the
high-speed USB or Ethernet ports, or messages can be distributed among any of the
eight user ports. The following is an example of a real world application:
 Com 1: NavCom proprietary corrections (x5B, x5C, etc.); transmit via 900 or 400MHz
radios
 Com 2: CMR+; transmit via 900 or 400MHz radios
 USB: Command and Control (StarUtil Interface)
 Bluetooth: Command and Control (StarUtil Interface)
 Ethernet Port 1: Command and Control (StarUtil Interface)
 Ethernet Port 2: RTCM v2.3
 Ethernet Port 3: CMR+
 Ethernet Port 4: RTCM v3.1 (can include Ntrip)
Refer to the Sapphire Technical Reference Manual, Appendix E, for RTK operation
information.
For IGS or similar permanent Base applications, NavCom offers a Choke Ring antenna
option to significantly reduce multipath errors on signal reception.
 NTRIP Support
The generation of differential GPS correction data is usually done directly on the GPS
receiver of a reference station, but this data can also be derived from observations
