The inReach to Cursor on Target Gateway (INRCOT) transforms Garmin inReach position messages into Cursor on Target (CoT) for display on TAK Products such as ATAK, WinTAK, iTAK, et al. Single or multi-device feeds are supported.

Other situational awareness products, including as RaptorX, TAKX & COPERS have been tested.

INRCOT requires a Garmin inReach device with service.

Use Cases

There are numerous applications for satellite based position location information, including:

  1. Wildland fire unit tracking
  2. Blue Force Tracking
  3. Search & Rescue (SAR)
  4. Partner Forces PLI
  5. Asset Tracking
  6. Data diode, CDS & cybersecurity considerations

See also Section 1114.d of the Dingell Act:

Location Systems for Wildland Firefighters.--
(1) In general.--Not later than 2 years after the date of
    enactment of this Act, subject to the availability of
    appropriations, the Secretaries, in coordination with State
    wildland firefighting agencies, shall jointly develop and
    operate a tracking system (referred to in this subsection as the
    ``system'') to remotely locate the positions of fire resources
    for use by wildland firefighters, including, at a minimum, any
    fire resources assigned to Federal type 1 wildland fire incident
    management teams.

Example Configurations

An example config:

[inrcot]
COT_URL = tcp://takserver.example.com:8088
POLL_INTERVAL = 120

[inrcot_feed_aaa]
FEED_URL = https://share.garmin.com/Feed/Share/aaa

Multiple feeds can be added by creating multiple inrcot_feed sections:

[inrcot]
COT_URL = tcp://takserver.example.com:8088
POLL_INTERVAL = 120

[inrcot_feed_xxx]
FEED_URL = https://share.garmin.com/Feed/Share/xxx

[inrcot_feed_yyy]
FEED_URL = https://share.garmin.com/Feed/Share/yyy

Individual feeds CoT output can be customized as well:

[inrcot]
COT_URL = tcp://takserver.example.com:8088
POLL_INTERVAL = 120

[inrcot_feed_zzz]
FEED_URL = https://share.garmin.com/Feed/Share/zzz
COT_TYPE = a-f-G-U-C
COT_STALE = 600
COT_NAME = Team Lead
COT_ICON = my_package/team_lead.png

Protected feeds are also supported:

[inrcot]
COT_URL = tcp://takserver.example.com:8088
POLL_INTERVAL = 120

[inrcot_feed_ppp]
FEED_URL = https://share.garmin.com/Feed/Share/ppp
