 | disStructureTransmitterPacket Fields |
[This is preliminary documentation and is subject to change.]
The disStructureTransmitterPacket type exposes the following members.
Fields| Name | Description | |
|---|---|---|
 | antennaParam |
Antenna Pattern Parameters.
These fields shall specify the radiation pattern from the antenna, its
orientation in space, and the polarization of the radiation, and shall be represented by an Antenna
Pattern Parameter record (see 5.2.4).
|
| bandwidth |
Transmit Frequency Bandwidth. This field shall identify the bandpass of the radio defined by the
Radio ID field and the Radio Type field, and shall be represented by a 32-bit floating point number.
|
| cryptoKeyID |
Crypto Key ID. This field shall consist of 16 bits. The high-order bit, when cleared, shall indicate
that the crypto equipment is in the baseband encryption mode, and when set shall indicate that the
crypto equipment is in the diphase encryption mode. The lower-order 15 bits shall be interpreted as a
key identifier. If the crypto key identifier of the transmitter and receiver match, they shall be
considered to be using the same encryption key. Note that this crypto key identiÞer is not an actual
crypto key, the nature of which varies among encryption systems and is classified.
|
| cryptoSystem |
Crypto System. This field shall identify the crypto equipment utilized if such equipment is used
with the Transmitter PDU, and shall be represented by a 16-bit enumeration.
|
| entityID |
Radio transmission source.
|
| frequency |
Frequency. This field shall specify the center frequency being used by the radio for transmission. This
frequency shall be expressed in units of hertz, and shall be represented by a 64-bit unsigned integer.
|
| inputSource |
Input Source. This field shall specify which position, (pilot, co-pilot, first officer, gunnery officer,
etc.) or data port in the entity utilizing the radio, is providing the input audio or data being transmitted.
This field shall be represented by an 8-bit enumeration. The values of this enumeration shall be
independently specified for each entity type (see Section 9 of EBV-DOC).
|
| location |
Antenna Location.
This field shall specify the location of the radiating portion of the antenna, and
shall be represented by an Antenna Location record (see 5.2.3).
|
| modulationLength |
Length of Modulation Parameters. These fields shall specify the length in octets of the modulation
parameters that follow this field. This length shall include any end padding necessary to assure that
the modulation parameter Þeld ends on a 64-bit boundary. Consequently, the value of this Þeld shall
be a multiple of 8. This Þeld shall be represented by an 8-bit unsigned integer.
|
| modulationParam |
Modulation Parameters.
These fields shall specify modulation type specific characteristics
of the radio transmission. The interpretation of this field shall depend on the value of the System
field of the Modulation Type record (see 5.2.23). The interpretation of this field for each value of
the System field is speciÞed in Section 9 of EBV-DOC.
|
| modulationType |
Modulation Type. This field shall specify the type of modulation used for radio transmission. The
modulation type shall be represented by a Modulation Type record (see 5.2.23).
|
| padding |
16 bit padding.
|
| padding2 |
8 bit padding.
|
| padding3 |
8 bit padding.
|
| padding4 |
8 bit padding.
|
| patternLength |
Antenna Pattern Length.
This field shall specify the length in octets of the Antenna Pattern Parameters
field. This length shall include any end padding necessary to assure that the Antenna Pattern
Parameter field ends on a 64-bit boundary. Consequently, the value of this field shall be a multiple of
8. This field shall be represented by an 16-bit unsigned integer.
|
| patternType |
Antenna Pattern Type.
This field shall specify the type of representation used for the radiation pattern
from the antenna. The value of this field shall determine the interpretation of the Antenna Pattern
Parameter field. This field shall be represented by a 16-bit enumeration (see Section 9 of EBV-DOC).
|
| pduHeader |
DIS PDU header.
|
| power |
Power. This field shall specify the average power being transmitted in units of decibel-milliwatts,
and shall be represented by a 32-bit floating point number.
|
| radioID |
Radio ID. This field shall identify a particular radio within a given entity. Radio IDs shall be
assigned sequentially to the radios within an entity, starting with Radio ID 1. The combination of
Entity ID and Radio ID uniquely identify a radio within a simulation exercise. The Radio ID field
shall be represented by a 16-bit unsigned integer.
|
| radioType |
Radio Entity Type.
This field shall indicate the type of radio being simulated, and shall be represented
by a Radio Entity Type record described in 5.2.25.
|
| relativeLocation |
Antenna Location.
|
| transmitState |
Transmit State. This field shall specify whether a radio is off, powered but not transmitting, or powered
and transmitting, and shall be represented by an 8-bit enumeration. (See Section 9 of EBV-DOC).
