Facility Database Format
The facility database is comprised of a total of three files. You can create your own facility database by following the format required by STK. For example, the stkFacility database (the database shipped with STK) includes the following files:
| File | Contents |
|---|---|
| stkFacility.fd | Main database file |
| stkFacility.fn | Facility networks |
| stkFacility.gd | Latest update information |
The first file contains fixed-width fields, where one row represents a single entry. The remaining are in the standard STK database file format. For more information, refer to the Accessing an Aircraft, City, Facility, Satellite, or Star Database page.
Source information can be found in Operator List file (C:\ProgramData\AGI\STK 12\Databases\Facility\Operator List.txt).
stkFacility.fd File
This is the main facility database file; it contains all searchable fields. The format, starting at column zero (0) is as follows:
stkFacility.fd file description
| Column | Width | Description |
|---|---|---|
| 0-36 | 37 | Site Name |
| 37-48 | 12 | Network (e.g., USAF) |
| 49-58 | 10 | Latitude (deg) |
| 59-69 | 11 | East longitude (deg) |
| 70-76 | 7 | Altitude (m) |
| 78-89 | 12 | Central Body |
stkFacility.fn File
This is the network file. It contains a list of all the valid facility network types. This file is used to build the list of facility networks available in the user interface. If this file isn't available, STK is unable to search for facility networks. The file is in a basic STK data file format.
