[aprssig] Rocket Tracking

[spam8mybrain]

She should Google for "amateur rocketry" and "tracking". There have been lots of discussion about different ways of getting GPS and telemetry down from a rocket to a chase vehicle. Basically, it should be the same as for a high-altitude balloon launch, just the flight stages will be progressing faster.
    
The issue is that most handheld radios don't have a good way to display the information, even if the radio alone is capable of decoding and interpreting the data without extra hardware. In that respect, the Kenwood TH-D72 and TH-D74 are probably the best bet, as they can decode APRS and display it on the radio screen, with even a direction-to-station vector based on the receiving radio's own GPS fix versus the APRS position report.Of course, this won't work if the rocket is using non-amateur frequencies or not APRS protocol for the data. I actually added support to my APRS client program to support a rocket using an ISM-band radio link to forward the rocket's GPS data as raw NMEA sentences instead of APRS packets.Again, she needs to find out more details about the downlink than just "ham radio".Andrew, KA2DDOauthor of YAAC ("Yet Another APRS Client")

I recently met a new ham who got her ham license because she is into model rockets. She does the large scale ones that go thousands of feet high. They have tracking and telemetry systems on board. However, she doesn't know what it uses, just that it is ham radio. She wants to get a handheld radio that will track her rocket. I'm going to guess this is APRS. Anybody familiar with this? Any recommendations of what she should get for a radio?Thanks.-- 73,Michael WA7SKG"Any day you do not learn one new thing is a wasted day."_______________________________________________aprssig mailing listaprssig at lists.tapr.orghttp://lists.tapr.org/mailman/listinfo/aprssig_lists.tapr.org
