I'm trying to write my own pass prediction program for tracking FM satellites. This program will this notify the users of upcoming passes via APRS messaging. I would like to find an algorithm that will predict AOS/LOS time and azimuth and the maximum elevation. I'm also hoping this algorithm will not be too computationally intensive as it may possibly be used for hundreds of different station locations.

[amsat-bb] HF Satellite Relay
Heard today of a Passive HF relay satellite being proposed. Wondered if Hams could relay off of it. It's a 10m diameter sphere. I assumed a 10m signal and 1000 Watts And antenna gains at both ends of 10 dB. Unless I made a dumb error, it looks impossible? I get a received signal of -170 dBm Compared to a good HF receiver of -122 dBm So its 48 dB down in the noise. Going to narrow band, could improve things, but the Doppler of +/- 600 Hz would make that difficult. Anyway, if someone else wants to double check the link budget using the radar range equation, go for it. The beauty of this system is that it is perfectly spherical, so the reflection coefficient would be constant within 1 dB. That is the advantage over trying to use the ISS or other large rocket body... They vary by 20 dB making communication by reflection impossible. Oh, and it would be in space for 30 years or more. So with something that reliable, it would be worth developing an amateur capability to use it. It is not designed for comms, but as a calibration sphere for over the horizon radars that have LOTS more power and LOTS more gain than we do. Bob, Wb4APR ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: SatPC 32 CAT / track doppler in my ICOM 910H
First, are you using a real serial port or a USB-to-serial adapter? Second, have you confirmed that the software and the radio are both set to the same baud rate and device address? And finally, what CAT delay setting are you using in SatPC32? Mine works perfectly with either type of interface at 9600 baud, default address of $60, and a CAT delay of 70.

[amsat-bb] Re: Pass prediction algorithm
... This program will this notify the users of upcoming passes via APRS messaging. Better to use OBJECTS so that all of the following shows up on the front panel of the radio: Satellite Name Direction, and Range Uplink Freq (and doppler) Downlink Freq and Doppler Elevation (HIGH or LOW). Direction of movement I would suggest you look at the digi_ned source code. It works great and does everything you want. [that is, sending out all the Satellite Objects info on APRS shown above] There was a change on the last update where he replace the display of azimuth/elevation to HIGH(over 30 degrees) and LOW (Below 30 degrees). That change actually works very well when driving down the road. And if it is like the original APRSdata.EXE, those are encoded with a leading % sign so that the D700 radio with a voice chip will actually SPEAK HIGH and LOW so you never even have to look at the radio. For example, you are just driving down the road, and your D700 (with voice chip)announces: AO-51 435.300 -5 KHz 145.85 +1 KHz HIGH And if you look at the radio, it displays all the other info above. This is just part of the local INFO that can be pushed to the front panel of the APRS radios as a service to the mobile operator. I'm glad you are taking on this challenge, because, no one uses the original APRSdata.EXE that did this, there are very few DIGI-NED's on the air doing it, and so we need a Windows version that each local area can run to serve their users.

[amsat-bb] Re: field day
We managed 21 contacts in all... one on each FM bird and the remainder on the linear sats. And all in spite of several visits from Mr. Murphy and his extended family: We ran N3FJP network logging for the first time, with MS NetMeeting as a chat client, and either one of them was conflicting with SatPC32, or my poor old Dell Inspiron 8100 laptop was just not up to the task. Every so often when I changed satellites, or changed CAT selections for a given satellite, SatPC32 would throw an access violation error. Seemed to keep working okay, though. Then I had an issue where the radio kept coming up in Normal tracking mode, even when it should have be in Reverse tracking mode, followed by 3 serious error blue screen reboots. My rotor has a bad spot on the azimuth position pot, so every once in a while, it would go zooming off target and I'd have to go manual; the mic boom broke off my headphones, and of course, it wouldn't be Field Day in Chicagoland without severe thunderstorms rolling thru at some point (Sunday morning - took us off the air for about an hour and a half). I was very impressed at how well AO-7 held up under the abuse she was subjected to. There were a couple of stations that had the poor old girl FM'ing so bad you couldn't even understand them, and one CW station that chirped so bad I swear they were keying an FM rig on the uplink! AO-51 V/S was a treat, and some observers couldn't believe how strong the downlink was with just a corner reflector on the K5GNA downconverter. Nice to have SO-67 back, too!

[amsat-bb] US Space Policy - Export Restrictions
Do I detect a very slight loosening of the Export Restrictions with regard to Space in the new policy released Monday. Compare below with 12 Effective Export Policy in the 2006 version. National Space Policy of the United States of America http://www.whitehouse.gov/sites/default/files/national_space_policy_6-28-10.pdf Effective Export Policies Consistent with the U.S. export control review, departments and agencies should seek to enhance the competitiveness of the U.S. space industrial base while also addressing national security needs. The United States will work to stem the flow of advanced space technology to unauthorized parties. Departments and agencies are responsible for protecting against adverse technology transfer in the conduct of their programs. The United States Government will consider the issuance of licenses for space-related exports on a case-by-case basis, pursuant to, and in accordance with, the International Traffic in Arms Regulations, the Export Administration Regulations, and other applicable laws, treaties, and regulations. Consistent with the foregoing space-related items that are determined to be generally available in the global marketplace shall be considered favorably with a view that such exports are usually in the national interests of the United States. Sensitive or advanced spacecraft-related exports may require a government-to-government agreement or other acceptable arrangement. 2006 US Space Policy http://www.fas.org/irp/offdocs/nspd/space.pdf 1996 US Space Policy http://www.fas.org/spp/military/docops/national/nstc-8.htm 73 Trevor M5AKA Daily Amateur Radio Email/RSS News: http://www.southgatearc.org/ Email Your News To: editor at southgatearc.org Or Upload Using Form At: http://www.southgatearc.org/news/your_news_1.htm ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: HF Satellite Relay
Well, it's finally happened. We've come full circle. They've reinvented Echo-1. http://en.wikipedia.org/wiki/Project_Echo Of course, that one was 10x larger. What makes this a 10m (band) operation? I expect it would work on the higher bands too, especially with the smaller size. What band did they use ~50-ish years ago? Greg KO6TH From: bruni...@usna.edu To: amsat-bb@amsat.org Cancel Date: Mon, 28 Jun 2010 13:44:45 -0400 Subject: [amsat-bb] HF Satellite Relay Heard today of a Passive HF relay satellite being proposed. Wondered if Hams could relay off of it. It's a 10m diameter sphere. I assumed a 10m signal and 1000 Watts And antenna gains at both ends of 10 dB. Unless I made a dumb error, it looks impossible? I get a received signal of -170 dBm Compared to a good HF receiver of -122 dBm So its 48 dB down in the noise. Going to narrow band, could improve things, but the Doppler of +/- 600 Hz would make that difficult. Anyway, if someone else wants to double check the link budget using the radar range equation, go for it. The beauty of this system is that it is perfectly spherical, so the reflection coefficient would be constant within 1 dB. That is the advantage over trying to use the ISS or other large rocket body... They vary by 20 dB making communication by reflection impossible. Oh, and it would be in space for 30 years or more. So with something that reliable, it would be worth developing an amateur capability to use it. It is not designed for comms, but as a calibration sphere for over the horizon radars that have LOTS more power and LOTS more gain than we do. Bob, Wb4APR ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: field day
Everything worked right this year for the Houston MosQRPitos, operating as W5MSQ near Brookshire, Texas. We were set up for all possible satellite configurations including Mode S down via AO-51, but I slept through both passes! However, it was great to find AO-7 and FO-29 in good shape and fantastic ops via HO-68. It may have only been one pass at the end of the event, but it was a GOOD one. Thanks to all for the many satellite QSO's. Be sure and send in your scores! 73 de Andy W5ACM (AMSAT Life Member) for W5MSQ - Original Message - From: Joe n...@mwt.net To: amsat-bb@amsat.org Sent: Monday, June 28, 2010 8:04 PM Subject: [amsat-bb] Re: field day I remember working ya on HF someplace. we were wb9fdz Field Day Zombies Joe WB9SBD The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 6/28/2010 3:59 PM, davekn...@aol.com wrote: We had a Blast also during FD!

AO-7 sounded like a 20M pile upgrin. ven the S band operation on AO-51 was busy. With so many stations on the atellites should we not have more AMSAT members? Defined as more dues paying nd contributing members. This is rocket science and as I been preaching, this s rocket science and that ain't cheap. 73 Bob W7LRD ___ Sent via amsat...@amsat.org.
