HI, Right Ascention of the Ascending node. The point in the orbit at which it crosses the equator going northbound. Here 's a good example: http://www.pe0sat.vgnet.nl/satellite/ 73 Dave, G4DPZ On 24/01/14 08:59, Lizeth Norman wrote: *HI all,Found this at this page:http://www.amsat.org/amsa

Right Angle (of the) Ascending Node? I think I got it. Much to play with here. Norm n3ykf On Fri, Jan 24, 2014 at 4:38 AM, David Johnson wrote: > HI, > > Right Ascention of the Ascending node. > > The point in the orbit at which it crosses the equator going northbound. > > Here 's a good example

Yes, but one thing I've never quite understood was how to convert RAAN into Longitude. All the neat explanations on non-earthly frames of reference and vernal equinoxes stop short of explaining how to start with RAAN (in a set of elements) and compute forward in time from the epoch to get the

[amsat-bb] Auburn Sat

Is the Auburn Sat operational? Are the KEPS in the Celtex? What is it's number. Just worked W1AW/2 FM 30 on SO 50 Pass. The new K4AMG circular M2 antennas and AR2 SW Preamps are working great. Will be on other birds this weekend as time permits. God Bless W4BUE K4AMG Club __

[amsat-bb] M2 large CP yagis for sale

I have a 2m-cp22 and 436-cp42ug for sale or trade. These antennas need a little bit of work, mainly straightening of a few elements, nothing major though. Great for sats obviously, but also superb for terrestrial and meteor scatter. These sell new for ~350 each. At the same time, I am in need o

[amsat-bb] ARRL Centennial

Hello, I’ve had a few Satellite operators ask me what’s the point of making contact with any of the W1AW portable stations when a few states at the beginning of the event were not on the air therefore not being able to work all states for an award. The rules indicate that each state will have

[amsat-bb] Re: [Starcom-bb] ARRL Centennial

I agree. Unfortunately, it doesn't seem likely that we'll get all 50 active on the satellites and some of us probably couldn't work all 50 (Hawaii remains a theoretically possible but very difficult dream for me). I still look forward to working as many W1AW/? operations on the satellites and

Hi Rich, Check your satellites list to be sure that you have all the ones you want set for "Show On/Off (it puts an asterisk next to them when Show is on). 73 Jerry N0JY On 1/24/2014 9:35 PM, Rich/wa4bue wrote: What have I done wrong? Trying different options I have loss multi sat views.
