Technical Data Declaration (Jan 1997)
The Contractor, NavCom Technology, Inc., hereby declares that, to the best of its knowledge
and belief, the technical data delivered herewith under Government contract (and subcontracts,
if appropriate) are complete, accurate, and comply with the requirements of the contract
concerning such technical data
Global Positioning System
Selective availability (S/A code) was disabled on 02 May 2000 at 04:05 UTC. The United States
government has stated that present GPS users use the available signals at their own risk. The
US Government may at any time end or change operation of these satellites without warning.
The U.S. Department of Commerce Limits Requirements state that all exportable GPS products
contain performance limitations so that they cannot be used to threaten the security of the
United States.
Access to satellite measurements and navigation results will be limited from display and
recordable output when predetermined values of velocity and altitude are exceeded. These
threshold values are far in excess of the normal and expected operational parameters of the
NCT-2000D and NCT-2100D family of products.

StarUtil User Guide – Rev. G
Revision History
Added a Note regarding message B0. (B0 at the default rate of On
Change is 1Hz regardless of the nav rate setting. To set the output of B0
at a higher rate to match the output of B1, use the NCT Binary Messages
window.)
Updated Figures 18 and 42 to show B0 set at 5Hz instead of On Change
in the NCT Binary Messages window, as an example of scheduling B0 to
Rev G (Apr 2009)
Rev F (May 2008)
a higher rate to match B1.
Added an updated StarFire Satellite table for Software v5.1.6 and later.
Indentified the original StarFire Satellite table as pertaining to Software
v4.2.26 and earlier.
Corrected the valid range for a Base site ID. The corrected range is
“1 to 1023”. The incorrect range was “0 to 1023”.
Added “Failed Search” section describing receiver functionality after a 5
minute failed search for a StarFire satellite.

Proprietary (RTK) is for surveys under 10 km. Proprietary Long Baseline
(UltraRTK™), is for surveys from 10 km to 40 km.
9 Obs./Correction Rate: Do not change the default, every 1 second. It is the optimum rate.
CMR+ (RTK) is set at a pre-determined rate that can not be changed.
9 Base Position Output Rate: Do not change the default, which is the optimum rate. The
default for Proprietary (RTK) and Proprietary Long Baseline (UltraRTK™) is every 10
seconds. The default for all RTCM message formats and CMR (RTK) is every 10
corrections. CMR+ (RTK) is set at a pre-determined rate that can not be changed.
Proprietary (RTK) and Proprietary Long Baseline (UltraRTK™) only:
• The option, Obs./Correction Rate, applies to:
• Message 0x5B for Proprietary (RTK)
• Message 0x5E for Proprietary Long Baseline (UltraRTK™)
• In either configuration, the option, Base Position Output Rate, applies to message
0x5C.
When the base is configured for Proprietary RTK, messages 0x5B and 0x5C are
automatically scheduled for output in the NCT Binary Messages window. When
the base is configured for Proprietary Long Baseline (UltraRTK™), messages
0x5E and 0x5C are automatically scheduled for output in the NCT Binary
