StarUtil-2110 User Guide – Rev. B

Refer to Figure 8 for the options in the sections below:

 Click the Apply button and then click the Retrieve button to confirm that the

receiver accepts new settings.

Navigation Rate and Other Options

9 Elevation Mask: Enter a value between 0 and 90 degrees to set the elevation angle at which

the receiver will start processing GPS data from satellites.

 The default elevation mask is 7 degrees to prevent position jumps due to

frequent satellite re-acquisitions at lower elevation mask angle limits.

9 Navigation Rate: The number of navigation solutions per second. The available rates are:

1Hz (default), 5Hz, and 10Hz. The 5Hz and 10Hz navigation rates are purchased software
options. The upload of a purchased navigation rate changes the setting in the Navigation
rate field automatically to the purchased rate. Refer to Chapter 7 Load Software for
information about the purchase and upload of software options.

 The Navigation Rate setting in the Rover / Navigation & Tracking Setup window

sets the output of the NCT Binary messages B0 and B1 and the NMEA messages
GGA, RMC and VTG provided that those messages are set to On Change in the
NCT Binary Messages window and the NMEA Messages window, respectively
(see Figure 9).

Figure 9: Navigation Rate

 When a message is set to On Change, the data is output each time new data is

available as determined by the Navigation Rate setting. For example, if a position
is steadfast at N 33
the Navigation Rate is 5Hz, a 0xb1 solution is output 1 time because the position

º

didn’t change. If any element of the position changes continuously during the
three second period then a 0xb1 solution is output 15 times.

9 Min SVs for Solution: Accept the default of 4 satellites, or enter a higher number. Four

satellites are the minimum SVs required for a 3D navigation solution, plus an acceptable
PDOP.

9 Max PDOP for Solution: The maximum PDOP value at which the receiver will compute

positions is 25.5. Enter the highest PDOP value according to application requirements. An
applied value above 25.5 reverts to the default of 10.0.

 The default setting for Max PDOP is 10. The quality of GPS data is dependent on

the geometry between the receiver and satellites; this includes the number of
satellites that can be "seen" by the receiver and the angle between the receiver
and satellites as a constellation seen by the receiver. A satellite near the horizon
usually provides a lower quality signal because of greater atmospheric
interference and the increased likelihood of the signal reflecting from surface
features; this is known as "multipath" error. The effect of geometry on GPS
quality is measured by PDOP (position dilution of precision). PDOP is the overall
measure of the precision obtainable with a given satellite geometry. For example,
a PDOP of 4 or less yields excellent precision, a PDOP between 5 and 7 is
acceptable and a PDOP of 7 or more is considered poor.

9 2D/3D Solution Mode: Click the Auto or Manual button to determine how height will be

applied to a 2D navigation solution.

• Auto: Sets the receiver to automatically transition between 3D (4 satellite) and 2D (3

satellite) navigation. This can also be determined by DOP values, even if 5 satellites are
available. In 2D navigation, the last valid computed height measurement is used.

• Manual: Enter the Height hold

value to set the receiver to 2D (3

satellite) navigation with the
Height hold value used for the
height measurement. The
receiver must compute an initial
3D navigation solution before it
transitions to 2D navigation. After
2D navigation is established, the
receiver will not transition back to
3D navigation.

 Click the icon in the toolbar

to view the current navigation
solution and other parameters of

indicates if 3D navigation is
computed (see Figure 10).

antenna (the element) to the Mechanical Reference Plane (MRP). The MRP is at the
bottom of the BSW antenna mount. The range limits are -128 to 127.

• Radius of Antenna Body (R): The measurement in millimeters from the physical center of

the antenna to the edge of the antenna. For a pole, enter 0. For a tripod, the range limits
are -32768 to 32767.

• Slant Range of Antenna Body: For a pole, the vertical measurement in millimeters from

the Mechanical Reference Plane (MRP) to the control point. For a tripod, the
measurement in millimeters from the edge of the antenna to the control point. The range
limits are -32768 to 32767.

9 Use Antenna Bias: Click the Yes or No button to apply the values set in the Vertical Antenna

Bias window to measurements.

9 Use SET Corrections: Click the Yes or No button to apply Solid Earth Tide (SET) corrections

to measurements.
Requirements for output of SET corrections:

• Message 0x49, W6 B6 set to Apply Correction

• NCT SET scheduled for output in the NMEA

Messages window (see Figure 13)

• A license for the StarFire subscription service. The

option, RTG input, must be set to Use on the Rover /
Tracking & Navigation Setup window.

• Valid Navigation

• Valid SET correctors (A minimum of 1 run of the SET

algorithm. These are an integral part of StarFire
corrections.)

Figure 13: NCT SET

If the criteria above are met, the receiver applies the SET corrections to the position
solution. The B1 Solution tab displays SET North, East, and Up corrections in millimeters
(see Figure 10).

 SET refers to Solid Earth Tides. Positions with SET provide better vertical

(primarily) and horizontal positioning accuracy, to account for gravitational effects
placed on terrain from celestial bodies (i.e. the Sun, Moon, etc.).

The SET message output via the NMEA port is a NavCom proprietary NMEA type
message. It conforms to the header, checksum, and electrical characteristics of a
standard NMEA string, but is not recognized by the NMEA governing body as an

the NMEA Type message structure.

9 RTCM Station ID: The default 0

configures the receiver to accept
corrections from any RTCM Station.
Enter a specific RTCM Station ID to
accept corrections only from that RTCM
Station.

9 Max dGPS Age: Enter the maximum

amount of time in seconds the received
correction will be used in case of an
outage or drop in the reception of
corrections. The time must be within the
max dGPS age limit, which is 1200
seconds. The default is 300 seconds.
