Floyd Magnet School MIR/APRS Test

On 27 April,1998 myself (KD4CGA) and Mike (KB4JHU) setup Amateur Radio equipment to show some students at Floyd Magnet School in Montgomery,Al how APRS (Automatic Position Reporting System} via the MIR Space Station worked.

MIREX had set times {1000 UTC- 2300 UTC) for schools throughout the world to work MIR using the APRS system. On the 0823 hr pass,we were all setup and waiting for the first signal from the MIR Space Station. The students were tracking MIR with the STSPLUS tracking program on one computer and watching for stations to show up on the APRS maps on the internet APRS site as well as the APRS (MIRMON) program that was running in the classroom.


After the pass was over (10 Min), I called MIREX on the conference line and was informed that the radio equipment on MIR was not in the digital mode. MIREX was trying to contact MIR to advise the crew to switch the radio mode to digital. Still nothing for the next few passes!!!

This is a quick summary of the 27/28th MIR School Day test. The purpose of the test was to allow schools and students an opportunity at a successful packet exchange with MIR, and to demonstrate the use of <UI> BULLETINS for communicating MIREX information to all monitoring stations. Other objectives were to demonstrate the use of internet linked ground stations to merge their data into a common internet feed and to demonstrate the use of ground station generated pseudo GPS positions digipeated by the spacecraft to show its realtime position.

The MIR TNC was off for the day of the announced test (27th), but was on for three early morning passes on the 28th. A total of 27 schools or other participating stations were successful during the day-after test. All stations reported their position and status and there were several messages exchanged. Most stations reported receiving the MIR BULLETINS and the MIR position packets. On the 29th several more stations were reported in the Western USA and South Africa. The results are posted on the Academy MIREX page http://web.usna.navy.mil/~bruninga/mirex.html
where you can also see the live daily captured downlink files. THis page scored 1300 hits during the event, and a total of 2800 since the experiment was announced at the first of April. The test is now over.

The three internet linked ground stations provided a continuous feed from the USA, Madrid and Taiwan (telnet to APRServe at port 10001). The live WEB page www.mirex.net was operational on the 27th when
there were no packets but died overnight. It was restored at the last minute on the 28th but only caught a half dozen live packets. It remains live now.

We wish to thank the MIREX team and Dr. Larsen N6CO for making this test possible.

Here are the bulletins transmitted by other MIREX Ground Stations: BLN1 :Kids are our Future in Space so Study Hard - The MIREX TEAM
BLN2 :WWW.MIREX.NET is currently showing stations on this SCHOOL TEST
BLN3 :Please do NOT connect to R0MIR-1 during SCHOOL TEST - Thank You
BLN :School Test Continues on 28th!

The three linked MIREX ground stations were: EA4RJ-2, BV1AF and W3ADO
