[OZAPRS] Direwolf and satellites

[vk4tec at tech-software.net]

We are trying to see every packet in this

 

http://59.167.159.165/

 

But we are using the APRS-IS which drops dupes and some ground stations are running direwolf is also dropping packets

 

I am using the APRS-IS as my transport and the above site as the dashboard

 

Might have to go down the satnogs idea – separate data warehouse feed

I'm not 100% sure, but I suspect Andrew wants a record of when multiple stations received a common packet, as a means of tracking station performance.

This isn't really the role of APRS-IS, and is more something which should be handled in either the receiver software (maybe sending stats out via station telemetry packets), or via some other statistics gathering method

 

I should note that the 'main' (maybe?) satellite AX.25 packet collection database (https://db.satnogs.org/stats/) does keep statistics of packets-per-contributor, but this database has a different purpose to APRS-IS, and the packets collected are *not* APRS compatible.

I don't follow.

The purpose of the APRS-IS is to capture a copy of every APRS packet
transmitted and make it available on the APRS web pages.

There is no need to capture dupes.  In fact, without dropping the
duplicate traffic we would be just overloading the network with a ten fold
increase in nothing but dupes.

Or am I missing something.

Hello

I have been sitting watching the last satellite pass of Falconsat-3

Direwolf was dumping packets like APRS-IS does due to dupes

So UNLESS we modify dire wolf and run an Independent server

We will never truly know the packets received by a Satellite Ground
Station.

I am willing to try a multi tread TCP server

But until dire wolf does dupe checking we are not going to get anywhere
