[amsat-bb] DUCHIFAT1 - first 'Compressed APRS' tests

[Herzliya Science Center]

Hi all,
DUCHIFAT1, the Israeli high school students 1U Cubesat is ready for first
public tests.
People with the ability to send Compressed APRS location packets are
invited to join the tests.
The satellite will collect these packets worldwide along its flight at
620km high orbit, and will downlink them from time to time over our ground
station in Herzliya/Israel.
Participants are kindly requested to register in advance in order to get
their packet identified on the map.
The packets successfully received will be displayed on a map in our
Internet site and  QSL cards will be sent via Bureau to the stations
registered and recognized. (unfortunately, there is no way we can recognize
packets from unregistered stations because the packet is limited to 14
character at the satellite, so we assign two unique characters to every
registered station to enable us to identify them).

Registration can be done at www.h-space-lab.org

Also available in that site are operational information about the
satellite, and the following documents:

*Configuring TT4 Explanation.doc* - how to use the Byonics TinyTrak4 for
generating Compressed APRS packets

*Terms Of Use.doc* - terms and techniques for making the best use of the
satellite

There is also Ground station software available for download, written by
our students around ISIS space Demodulator software.

We hope many people will find it interesting and enjoyable,

good luck!
