Hi,

I'm working on some documentation for Automatic Identification System (AIS) and I was wondering if it's possible to get entries key ship tracking systems? Tags for AIS (instrument and format), NMEA(format), NMEA TAG BLOCK (format), Vessel Monitoring System (VMS; instrument), ORBCOMM (platform), SpaceQuest's AprizeSat (platform) would be helpful. I'm sure I'm missing a bunch more critical ones. I see that GCMD has a keyword for RINEX for GNSS data which is more raw than NMEA, Spire who has AIS receivers on their satellites, etc., so it looks like these tags would fit into the space of keywords.

Happy to help craft the entries.

Thanks!

Thank you for your keyword request. We will review it and let you know when it is complete.

Can you provide more information for each one of these keywords?
• Keyword category (i.e. science, platform, instrument, format, etc.)
• Appropriate keyword hierarchy, see GCMD Keyword Viewer hierarchy as a reference
• Keyword short name and long name
• Keyword definition
• Keyword reference
