Which GPS satellites are currently in orbit?
I look at the table of satellite launches but I see no way to tell which satellites are currently in orbit. How can I tell which satellites are currently in orbit? RHB100 (talk) 20:32, 10 August 2009 (UTC)
I see that PRN 05 and PRN 08 are currently missing. All other PRN's from 1 to 32 are listed and there does not appear to be any repeats. Yet I have heard that there are 31 not 30 satellites in orbit. RHB100 (talk) 22:09, 10 August 2009 (UTC)
Answer: Any info that you don't see you may be able to find through the external links. PRN 08 is currently assigned to SVN 38 (block IIA). PRN 05 used to be assigned to SVN 35 (block IIA) before SVN 35 was decommissioned. Then PRN 05 was assigned to the last launched satellite SVN 50 (block IIR-M). As satellites are frequently launched or decommissioned, the number "in orbit" changes from time to time, about 4 times so far this year. It is currently 31 although only 30 are currently set to "healthy." ----W. Kelley, USNO, 27 Aug 2009
GPS 2F Series
Amazingly Wikipedia doesn't have anything (I can find) on the GPS 2F series which is an $8 billion 12-satellite upgrade which will bring civilian accuracy to within 2 feet. I would start an article but I am (considerably) confused on the naming structure for satellite articles.Americasroof (talk) 16:04, 27 May 2010 (UTC)
