Of the present invention towards mainly including two kinds of agreements in the communication of empty day, i.e. AOS agreement and Link agreement, below
Both agreements are described in detail.
1, AOS agreement
As shown in Fig. 2, information mainly follows the AOS association based on CCSDS when space link transmits in the communication of empty day
View.
In order to construct the network system of Incorporate, realize that space-based is docked with the seamless data of ground, space link is
Wireless satellite link, the AOS space link layer protocol that link layer uses the CCSDS committee to formulate, due to ground and space bottom
The difference of link, thus satellite link layer we be not available agreement identical with ground, but network layer can shield this difference.
Domain: consisting of two parts, and resets mark and free area needs to store when space link does not connect
Transmission frame needs to retransmit these data if link re-establishes.It resets mark domain and informs that these data of receiving end are real
When data " 0 " either replay data " 1 ".Its main purposes in a pseudo channel exactly when existing simultaneously data and again
Put data separation they, complete " 00 " is accustomed to being set in free area now.
Frame head portion Error Control: the domain is optionally, if having used the domain, for the position 48-63 on main head.The domain uses
Has RS (10, the 6) code of error correcting capability to protect key message MCID, VCID and the signaling domain in head.The presence in this domain
Whether once it is determined that, then must be consistent in each transmission frame of same physical channel.
It is inserted into domain: if used, the domain should be inserted in after main head, if physical channel enables in cycle data transfer
The business, then, even empty transmission frame, also including this region in each frame of physical channel transmission.Insert district
The length in domain and the NI_SDU equal length of physical channel, insert region include an IN_SDU as unit of byte.
Data cell domain: data field unit domain follows main head or insert region closely, includes a M_PDU, a B_
PDU, a VCA_SDU or empty data.M_PDU, B_PDU, VCA_SDU and empty data will not be multiplexed into a pseudo channel,
Such as: if a pseudo channel transmits M_PDU.It include a M_PDU so in each transmission frame of this pseudo channel, this
Regulation is because identifying the type of transmitted data, if mixed transport, recipient there is no a domain in transmission frame
It can not identify the type of data, if not having user data to need to send when sending transmission frame, one includes spy
The transmission frame of the empty data for the formula that fixes is sent, and so a transmission frame is referred to as null frame.The VCID of null frame is set as complete " 1 " number
Length according to region is as unit of byte, and is variable, but be equal to both following difference:
1) length of the transmission frame of particular physical channel.
2) length on main head is plus the length of insert region and/or the length of tail portion.
Tail: being all Optional Field comprising operation control domain OCF and frame error control domain.The use of OCF is more special
Very, different according to different pseudo channels, once use, within fixed task time, each pseudo channel it is every
It all include this domain in a frame.First bit of OCF is type code position, for indicating the Report Type wherein loaded, " 0 "
Representative is the report of Class1, and what " 1 " represented is that type 2 is reported.Frame error control domain provides discovery transmission and data are processed
Lead to the ability of transmission frame (in addition to head) mistake in journey, it use whether according to lower layer's coding layer provide ability not
It is same and different.
With the increase of new applications various in space-based asset, application type is more and more abundant.More more tired, answer on more ground

2 corresponding to 5bit5(0-31) mark value indicates；M is by the 3bit corresponding 2 of the sub-mark symbol field of banner word3(0-7) son
Mark value indicates.It can thus be concluded that 32 × 8=256 kind message format, and the message of each number has uniquely determined a kind of report
The type of text.
Header is to send at the beginning of each time slot, and the message of Link-16 data link system connects after header
Face is sent.Header is not the message of Link class data link system, its information content mainly assists platform device to handle Link
The message of class data link system.Header word has 416 altogether, by 16 double pulse sets at.Header word is made of 35bit information, by it
Be divided into 7 groups of 5bit, and the coding of (16,7) RS is carried out to it.
The header word of Link-16 agreement is divided into four parts, is Slot Type field, RI/TM field, track number mark respectively
Character learning section, secure data unary system row field.The Slot Type field of 3bit, effect are primarily used to the envelope of mark message
It whether fills in type, type of message (formatted message or variable format message) and free text comprising error correcting code etc.；
(RI/TM) character field of 1bit, for the character of this 1bit when being transferred from by text, mark is using pulse or double arteries and veins
Character is rushed, and when transmitting fixed format message or variable formatting message, judge that relaying for transmitting is also non-relaying
Message；The number of the emission source of the main storage current time slots of track number mark of 15bit；The secure data cell-in-series of 16bit
The encryption method of the message of this time slot of number primary identity, to receive the decryption that terminal completes message.
