[aprssig] SmartBeaconing for Bicycle mobile

[Jim (List)]

I regularly do events with vehicles on fixed timing at 1 minute intervals, with 5 seconds between each (=12 mobiles).

 

We don’t use 144.800 (way too much traffic being generated!), instead setting up our own system with digi’s placed in the best locations for the event, and gating the information to APRS-IS servers for wider viewing.

 

That is with cars, if tracking bicycles perhaps 2 minutes would still give you a reasonable update (assuming 15kmh, that’s a beacon every 500m).

I did an event a few years ago with 5 ambulances and APRS trackers at 1min. intervals. That turned out to be a real mess. 1 min was way too often unless you are trying to target the object with missiles.

Might I suggest that you use a 5:1 ratio?

 

5 mins @ 2 mph with 1 min @ 10 mph?

Theoretically  that would update at the same delta distance between the speeds, making the track more 'regular', so to speak.

(almost like making the reports based on distance change instead of elapsed time)

Thank you.  I'll try 2mph @ 2 minutes and 10mph @ 1 minute tomorrow and 
see how it works out.  We're not in a very busy APRS environment here, 
so the 1 and 2 minutes shouldn't be a burden.  Especially not coming 
from a 5w HT.
