CHAPTER 3. CONF

GUR

NG THE ASTERX SB3

Antenna Location and Antenna Oﬀset

The AsteRx SB3 assumes that the main and auxiliary antennas are placed along the
longitudinal axis of the vehicle with the auxiliary in front of the main antenna.

f the antennas

cannot be placed in such a con

ﬁ

guration, the reported heading and pitch may be biased. The

default settings in the

Antenna Oﬀset

and

Antenna Location

ﬁ

elds shown in Figure 3-13

can be altered to compensate for these biases.

n many cases the antenna baseline will not align perfectly with the vehicle

’

s longitudinal axis

or its perpendicular and in these circumstances the provided attitude o

ﬀ

set value can also be

used to compensate for small angular deviations. Note that, in order to ensure the integrity
of the solution, o

ﬀ

sets greater than 5 degrees from the longitudinal axis or its perpendicular

are not recommended.

An increase in angle between the antenna baseline and the vehicle

’

s longitudinal axis in the

clockwise direction corresponds to a positive change in the value of the heading o

ﬀ

set To

better explain this, a few examples of possible setups are given below in Figure 3-13.

Figure 3-13:

Examples of a number of antenna setups and the corresponding

heading o

ﬀ

sets. a.) The default setup for which the angle between the antenna

baseline and the longitudinal axis is 0 and no heading o

ﬀ

set needs to be set. b.)

a slight deviation (5 degrees) from the longitudinal axis in the clockwise direction
is re

ﬂ

ected by a positive increase in the heading o

ﬀ

set. c.) An alternative antenna

con

ﬁ

guration where the antennas are placed perpendicular to the longitudinal

axis.

d.)

An alternative antenna con

ﬁ

guration where the antennas are placed

perpendicular to the longitudinal axis with a small deviation.

The examples above all relate to a heading o

ﬀ

set but the antenna orientation can also

be characterized by a vertical o

ﬀ

set. Vertical o

ﬀ

sets can be compensated for by adjusting

the Pitch o

ﬀ

set. This may be necessary in cases where the antenna baseline is not exactly

parallel to the longitudinal axis of the vehicle or in situations where the two antenna ARPs
