[aprssig] Autonomous EMCOMM Telemetry

We used the messh concept back in 1995 or 6 I think

for the SNOW-POLE system  PACcomm built for the

Army for use in Czech Republic.  It is when PacComm

introduced the original callsign substituting TNC's

so that once a snow-pole had digipeated a packet

it would not digipeat that packet again.  (That

was our RELAY system).


Problem was it would repeate all the other copies though

of its own packet digipeated by others.  That is the

RELAY dupe problem that we have finall gotten around

to forcing obsolete in 2004 to avoid all those dupes.


I proposed the WIDEn-N system back in 1994 but it

wsa not until 1998 that Kantronics put it in their TNC's.

It is a perfect MESH system.  Every station digipeats

it once and never again.

SNOW POLES, were APRS sensor package in large PVC pipe dropped out of Ch47 helos in Bosnia in 1995.

Has anyone come up with an APRS-based environmental telemetry sensor for EMCOMM use?


Specifically...having a "sensor/APRS kit" that one could drop-or-deploy into a theater and let it beacon back telemetry that would be of use to emergency first and second responders.



*	Wind speed, wind direction, temperature, humidity ... for chemical spills or forest fires
*	Water level ... to help manage flooding
*	Air transparency ... to help manage air pollution


Either drop-and-forget (like around a forest fire) or purposefully deploy (like, ahead of a flooding event)...but with the expressed purpose of providing valued telemetry of known quality.
