ARLA/CLUSTER: CBAPRS - Automatic Packet Reporting System for everyone...

[João Costa > CT1FBF]

What is CBAPRS?

*CBAPRS* stands for *C*itizen *B*and *A*utomatic *P*acket *R*eporting *S*ystem
which consists of a server listening for APRS packets relayed over the
internet by radio operators and a webinterface displaying the received
information on a map.

More information on APRS
<http://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System> is
available on Wikipedia.
Why yet another APRS map?

Relaying packets to other APRS maps is restricted to ameteur radio
operators. As more and more people are starting to use APRS on non amateur
radio bands, i.e. citizen band, the need for an open APRS map had to be met.
Under heavy development!

This project is under heavy development. It is nowhere near finished and
has plenty of bugs and features missing.
How to relay packets to you?

To send and receive packets from cbaprs.de please configure your APRS
software with the following settings:
*Host:* cbaprs.de
*Port:* 27235
Keep in mind that you might need to set a valid passcode for your software
to transmit packets to an internet server.
What packet formats do you support?

We currently support position reports in standard, compressed and Mic-E
format, status reports, object reports and weather reports in full format.
How long is a station visible on the map?

APRS specification suggests, that a station should be excluded from a map
after 80 minutes of inactivity. As long as this map is nowhere near
populated as amateuer radio maps the time after a station is removed is set
to *12 hours*! This may change in the future.
How can I measure the distance between an arbitrary number of points on the
map?

Enable the measuring tool located near the top left corner of the map (the
little ruler) and click on the map to start measuring from that point on.
Any further click will add a new point of measurement. When finished double
click on the destination point. The distance is displayed in kilometers
right above the ruler button.
I am sending a packet but it doesn't change the "last heard"-time of my
station.

To avoid duplicate packets in the database every packet is hashed in memory
and compared with new incoming packets. If a duplicate packet is received
in a short interval (5-10 minutes) it is discarded. This is only true for
packets with identical content.
Also take note that not every APRS data format is supported. Unsupported
packets are also discarded. But they are relayed by the server to other
stations!
How can I contact you?
