feature suggestion: Compressed Position Report Data Format

Closed this issue · 5 comments

Is there any plan to introduce compressed format in order to reduce the length of the payload, as in the future, increasing the number of trackers, the air time may get saturated quickly and reducing it for each tracker may be beneficial for the network.

Hello iw2ejh,

compressed position report data is included since the beginning and additionally MIC-E since 12/2023 in the tracker firmware (Position, Altitude, Speed, Beaing).

Default:
CALLSIGN>APLRT1,WIDE1-1:!/5ilCR,'&kJCQ
MIC-E
CALLSIGN>T8UU20,WIDE1-1:`(&EppA>/"7b}

Thanks for the info, I made a mistake, I was asking for the iGate, I saw the beacon sent to APRS-IS is in clear txt, I do not know if the beacon sent via RF is clear txt or compressed:
here what I saw via aprs-is >

No problem - every comment is welcome.
From iGate the beacon to aprs-is as well as to RF is not compressed.
