J-track is nice. I also use Heavens Above. You do need to register, but it's free.
For PRN32, once you log in, use spacecraft # 22657 (Navstar 32) This URL will show the current orbital track. http://www.heavens-above.com/orbitdisplay.asp?Session=kebgcpaanhagkcceebmhgcnb&satid=22657 For all the orbital kep elements I use Space Track. www.space-track.org 73, Mike N1JEZ AMSAT #29649 "A closed mouth gathers no feet" ----- Original Message ----- From: "Rex" <[EMAIL PROTECTED]> Subject: Re: [time-nuts] GPS PRN vs SV...?? > Tom Van Baak wrote: >>> Current status SVNs, PRN etc at: >>> >>> http://www.navcen.uscg.gov/navinfo/Gps/ActiveNanu.aspx >>> >> That's a good URL.
