Details relating to the contents of the SNS data items published in Parts I-S, II-S, III-S

and the Special Sections of the BR IFIC CD-ROM and the database that is provided on the

SRS DVD

General explanation of the tables

This document provides a description of the database that is provided on the SRS DVD in the

form of an MS-Access database (SRS_ALL.MDB1/SPS_ALL.MDB

2). This description can also be

considered to apply to the submission of Appendix 4 information on space services that was

announced in BR Circular Letter CR/211 dated 10th

May 2004. Software is provided on this DVD

which will facilitate the electronic submission of space notices.

The data are presented in the following pages in the form of relational tables. NOTE 1

(paragraph 1.1) gives a brief description of these tables. The tables can be considered as being divided

into four categories: Appendix 4 submitted data, BR data, reference tables and BR internal data. The

attachment describes all the tables in all these categories; however, for the purposes of electronic

submission, only the first category listed (Appendix 4 submitted data) should be considered by your

Administration. Additionally, only the data-items marked with x in the columns 4/2 or 4/3 of these

tables should be provided in the submission. There are data-items that appear many times in these

tables; they should be provided only if marked x in the columns 4/2 or 4/3.

Annex 1 to the attachment presents an entity-relationship diagram used as a basis for deriving

these tables; it shows the tables and their relationships. This diagram is also shown in Annex 3 with

the tables grouped into sets. Annex 4 presents the same diagram with only the tables that are required

for submitting notices for satellite networks under Appendix 4, Annex 2. Annex 5 presents the same

diagram showing only the tables that are required for submitting notices for earth stations under

Appendix 4, Annex 2. Annex 2 provides a cross-reference between the tables and the Ap4 Notice

Forms. Annex 6 provides an entity-relationship diagram showing only the tables relating to the

submitted data; the reference tables are not shown. A description of the columns that are in this

attachment is presented below:

1. Column Table Name

This column contains the names of the tables (which are the entities in the entity-relationship

diagram) according to which the data-items in the next column are grouped together.

2. Column Data-item

In this column, the data-items contained in the tables are listed. The data-items that are to be

submitted electronically are marked by an x in columns 4/2 and 4/3 (see paragraphs 5 and 6).

Data-items that are in bold italic type form the primary key of the corresponding table (NOTE 1

provides a definition of primary key).

1 Database containing notices in unplanned space services.

2 Database containing notices in planned space services of Appendices 30 and 30A of Radio Regulation.

3. Column Format

The format of the data-item is described here. It should be noted that this format is related to

the description of the field on the corresponding form of notice.

The Radiocommunication Bureau (BR) will accept these tables only as a Microsoft Access

Database file in the format described herein. BR has developed a PC-based software package

(running under MS-Windows) that permits the generation of electronic notices in MS-Access table

format as defined by this Circular Letter. This software is provided on the SRS on DVD and can be

also downloaded from the BRs web site.

The format descriptions used in the tables should be read as follows (this is not a COBOL

format but an XBASE type format):

Value Description

X used to describe alphanumeric data.

e.g. X(9) specifies a 9 character field containing alphanumeric data

XXX is equivalent to X(3).

9 used to describe digits

. shows the position of a decimal point

S implies a sign (sign leading separate)

e.g. S999.99 implies a numeric field with a range of values from -999.99 to +999.99

99 implies a numeric field with a range of values from 0 to 99

Null values for data-items (i.e. data-items that are not present in the submission) can be

provided as follows. Since the submission is provided in a Microsoft Access database file, all

data-items (alphanumeric and numeric) which are null should be specified as null (which is a valid

data value in the Microsoft Access database).

Files and file-names: all tables are contained in one physical file which can be provided with a

file-name containing a Windows compatible alphanumeric name ( typically 8 characters - up to the

choice of the Administration) followed by the extension .MDB.

4. Column 4/2 (applicable to satellite networks)

An x3 is specified in this column if the corresponding data-item is to be submitted according

to Appendix 4 (for a satellite network including submission under Article 2A of Appendices 30 and

30A). If nothing is specified in this column for a particular data-item, this implies that the data-item is

not to be provided.

3 See Annex 2 to Appendix 4 to know whether submission of a data item for a specific type of submission is optional or

mandatory.

5. Column 4/3 (applicable to earth stations)

An x3 is specified in this column if the corresponding data-item is to be submitted according

to Appendix 4 (for an earth station). If nothing is specified in this column for a particular data-item,

this implies that the data-item is not to be provided.

6. Column Plans (applicable to space plans Articles 4 and 5 of Appendices 30 and 30A,

Articles 6 and 8 of Appendix 30B)

An x 3

is specified in this column if the corresponding data-item is to be submitted

according to (or is applicable to) Appendix 4 (for the appropriate space plan). If nothing is specified

in this column for a particular data-item, this implies that the data-item is not to be provided. If the

column contains 30, 30A or 30B, then that data item is applicable only for that specific plan.

7. Column Description

A brief description of the corresponding data-item is provided here.

8. Column Comment

This column provides a brief remark for the corresponding data-item, if found necessary.
