RAIM (Receiver Autonomous Integrity Monitoring) can be set ON or OFF.
When set ON, RAIM will display SAFE, UNSAFE or CAUTION in below conditions:

Conditions for the "safe" state

The result of integrity calculation by means of RAIM will be stated as "safe", if the integrity
calculation can be performed with a confidence level above 95 % for the selected accuracy level
and RAIM calculates the probable position error to be within the selected accuracy level.
This generally requires at least 5 "healthy" satellites available and in a robust geometry, i.e. the
worst 4 satellite geometry is still suitable for navigation.

Conditions for the "caution" state

The "caution" status will be used to indicate:
– insufficient information to reliably calculate with a confidence level above 95 % for the selected
accuracy level, or
– the probability of false alarms >5 %, or
– the probability of not detecting an error condition >5 %.

Those conditions may occur if an insufficient number of satellites are available, for example 4 or 5
with 2 satellites "close" together in azimuth and elevation, causing the geometry to degrade to the
point that the RAIM calculation becomes unreliable. Note that the resulting accuracy based on 4 or
5 satellites in use may be within the selected accuracy level, but the RAIM algorithm cannot verify
it.

Conditions for the "unsafe" state

The "unsafe" status will be used if the integrity calculation is performed with a confidence level
above 95 % for the selected accuracy level, and RAIM calculates the probable position error
exceeding the selected accuracy level. Note that also here a robust geometry is required to reach
this confidence level. The "unsafe" state can be reached when satellite range errors degrade the
navigation solution, causing the resulting accuracy to be outside the selected accuracy level.

7.2.3 ACCURACY LEVEL

Accuracy level can be set between 10-100m.

8. INSTALLATION

8.1 INSTALLATION OF MAIN UNIT

The main unit can be installed on a table-top, on the overhead, or in a panel (optional flush
mounting brackets required). Refer to the outline drawings at the end of this manual for
installation instructions. When selecting a mounting location, keep in mind the following points:

• Locate the unit away from exhaust pipes and vents.

• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Locate the unit away from equipment which generates electromagnetic fields such as a motor or
generator.
• Allow sufficient maintenance space at the sides and rear of the unit and leave sufficient slack in
cables, to facilitate maintenance and servicing.
• Observe the following compass safe distances to prevent deviation of a magnetic compass.
Standard compass, 0.5 m, Steering compass, 0.3 m.

8.2 INSTALLATION OF ANTENNA UNIT

Install the antenna unit referring to the antenna installation diagram at the end of this manual. When
selecting a mounting location for the antenna unit, keep in mind the following points:

• Do not shorten the antenna cable.

• Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the
GPS signal.
• The location should be well away from a VHF/UHF antenna. A GPS NAVIGATOR is interfered
by a harmonic wave of a VHF/ UHF antenna.
• There should be no interfering object within the line-of-sight to the satellites. Objects within
line-of-sight to a satellite, for example, a mast, may block reception or prolong acquisition
time.
• Mounting the antenna unit as high as possible keeps it free of interfering objects and water
spray, which can interrupt reception of GPS satellite signal if the water freezes.
• If the antenna cable is to be passed through a hole which is not large enough to pass the
connector, you may unfasten the connector. Refasten it after running the cable through the
hole.

identified by 64+ satellite slot numbers. The slot numbers are 1 through 24 for the
full
GLONASS constellation of 24 satellites, thus giving a range of 65 through 88. The
numbers 89 through 96 are available if slot numbers above 24 are allocated to on-
orbit spares.
NOTE 2: GNSS System ID identifies the GNSS System ID according to the Table below.

1. Configured repeat interval (see Note 1)

2. Equipment status (see Note 2)
3. Sequential sentence identifier (see Note 3)

NOTE 1: Configured autonomous repeat interval in seconds. This field should be set to
NULL in response to a query if this feature is supported.

NOTE 2: Equipment in normal operation A = yes, V = no

This field can be used can be used to indicate the current equipment status. This could be the
result of an built-in integrity testing function.

NOTE 3: The sequential sentence identifier provides a message identification number from 0
to 9 that is sequentially assigned and is incremented for each new sentence. The
count resets to 0 after 9 is used.

9. Mode indicator (see Notes 2 and 3 )

NOTE 1: E = Easterly variation subtracts from True course

W = Westerly variation adds to True course
NOTE 2: Positioning system mode Indicator
A = Autonomous. Satellite system used in non-differential mode in position fix;
D = Differential. Satellite system used in differential mode in position fix;
E = Estimated (dead reckoning) mode;
F = Float RTK. Satellite system used in real time kinematic mode with floating
integers;
M = Manual input mode;
N =No fix. Satellite system not used in position fix, or fix not valid;
P = Precise. Satellite system used in precision mode. Precision mode is
defined as: no deliberate degradation (such as selective availability) and higher
resolution code (P-code) is used to compute position fix. P is also used for
satellite system used in multi-frequency, SBAS or Precise Point Positioning
(PPP)
mode;
R = Real time kinematic. Satellite system used in RTK mode with fixed integers;
S = Simulator mode.
NOTE 3 :The positioning system mode indicator field supplements the positioning system
status field. The status field should be set to V = Invalid for all values of the mode
indicator except for A= Autonomous, D = Differential, F = Float RTK, P = Precise
and R = Real time kinematic. The positioning system mode indicator and status
fields should not be null fields.

NOTE 4 :The navigational status indicator is according to IEC 61108 requirements on

‘Navigational (or Failure) warnings and status indications’. This field should not be
a NULL field and the character should take one of the following values:

S = Safe. when the estimated positioning accuracy (95 % confidence) is within the
selected accuracy level corresponding to the actual navigation mode, and/or
integrity is available and within the requirements for the actual navigation
mode, and/or a new valid position has been calculated within 1 s for a
conventional craft and 0,5 s for a high speed craft.

C = Caution when integrity is not available.

U = Unsafe when the estimated positioning accuracy (95 % confidence) is less than
the selected accuracy level corresponding to the actual navigation mode, and/or
integrity is available but exceeds the requirements for the actual navigation
mode, and/or a new valid position has not been calculated within 1 s for a
conventional craft and 0,5 s for a high speed craft.

V = Navigational status not valid, equipment is not providing navigational status

indication.
