16.6. S2087 Track files

16.6.1. Introduction

The S2087 system is able to provide ownship track. On occasions when the command system isn't able to provide ownship track then this data can be used as a fallback.

The following assumptions have been made regarding the data:

  • The file ends in .csv

  • Course is in degrees, and speed is in knots

  • Measured Time is recorded in GMT

  • Measurement time is stored in the SYS_ORDINAL_TIME column

[Note]Note

Local IT settings may hide the file suffix for MS Windows devices. So, a file titled context.csv may just appear as context, with MS Windows indicating that the file is a Microsoft Office Excel Comma Separated Value file.

16.6.2. File format

Here is a sample of the expected format (line-breaks inserted to aid legibility).
