‡
To access the Vertical Antenna Bias window from the main StarUtil window, click
the
icon or select Receiver > Setup > Vertical Antenna Bias.
Refer to Figure 11 for the options below.
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
