EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

Five CubeSats altitude
by Masahiro Arai 12 Nov '12

12 Nov '12

I'm ploting altitude of five CubeSats which were deployed from ISS. The results is interesting. First deployment satellites are lower altitude than laters. I guess this is related to initial velocity at deployment. First Deployment deployment order: #1 WE WISH, #2 RAIKO altitude: WE WISH < RAIKO Second Deployment deployment order: #1 TechEdSat, #2 F1, #3 FITSAT-1 altitude: TechEdSat < F1 < FITSAT-1 I'm also ploating ARISSat-1 on the same chart as its time line align to the five CubeSats deployment date. The chart shows five CubeSats have large decay rate than ARISSat-1. You can see the chart on the following URL. http://www.ne.jp/asahi/m-arai/gkz/5CubeSats_Altitude.png 73 Masa JN1GKZ Tokyo Japna

Hi All I have just returned from the AMSAT conference in Orlando FL one of the European is no longer flying the Clyde Space batteries because of performance issues. I would like to know the group thoughts on their batteries and lithium batteries in general. The AMSAT team is warning us about charging batteries below 0 deg c. In talking to many teams on ElaNa 4 there does seem too much concern about charging batteries cold. Please let us know your thoughts. If you desire we will not publish your responses.

a fun week in Florida!
by Patrick STODDARD (WD9EWK/VA7EWK) 31 Oct '12

31 Oct '12

Hi! I made it home an hour ago, after a great week in Florida. The AMSAT Symposium was great, and thanks to all of those who worked to put on this event. And, of course, having Hector CO6CBF at the Symposium made this even better. On my way home from the Phoenix airport, I stopped at my mailbox. I had more checks and money orders sitting in their for the so- called "Hector fund" that arrived in the past week. Again, many thanks to everyone who has sent or given me contributions to help with the expenses for this trip. It is obvious that this was extremely successful - just watch the video from Hector's presentation on Saturday to see that. I have incurred expenses related to bringing Hector to the Symposium totaling $2413.30, and received contributions totaling $1960.00! The expenses totaled a little more than I had originally estimated (I was working with an estimate of $2000 in the beginning), but I never thought I would have received almost $2000 in contributions!! If there are other contributions in the mail, I will add that to my spreadsheet and post an update later. I don't think I will need any other contributions toward this effort. THANK YOU ALL!!!!!!!! On my way home from the airport, I called Hector. He made it home OK, and is now in the process of clearing the gear he brought back from Florida through the processes of Cuban Customs and the Cuban communications ministry. This is normal, and he was confident he could get everything cleared without incident. Hector also said he hopes to be able to post a message here on the -BB tomorrow, in part to thank everyone that helped make his trip to Florida possible. Back to pulling more photos from my camera and mobile phone, and getting caught up on things before going back to work tomorrow. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/
