I am hesitating between buying the iPhone 4 and the iPad (or else?) to use as a VFR GPS. One of the attractive feature of the iPad is the larger screen but it is also one of the drawback... Apparently the iPhone has an internal Gyroscope which the iPad does not have (might be added on the iPad...

I have a dream. All IIA satellites retired. All IIF satellites in orbit. L2C signal set fully healthy with 19 operational satellites (12 IIF + 7 IIRM). L5 signal set healthy even though only 12 IIF satellites are broadcasting it. But their ranging signals are as perfect as predicted, not enough for...

Earth shattering news for GNSS, commercial availability of Chip Scale Atomic Clock (CSAC) For 1st generation CSAC, amazing: 16 cc volume (1 cu inch) 35 grams weight 115mW of power 4 orders of magnitude better clock stability than typical frequency

One airport I frequently use in the northeast has adopted an improvement plan which includes, along with a slight runway extension, the installation of a Transponder Landing System. The airport is currently served by a VOR approach and a GPS approach, but terrain considerations would almost...

Since March 1st, PRN 135 WAAS ranging has changed from NM (Not Monitored) to NPA (Non precision approach). From what I observed this wouldn't be possible with MT0 (test mode) being broadcast by said GEO. This is also typically the first step when a GEO is transitioned from Test mode into regular...

www.gpsworld.com informs that PRN135 is now back to full healthy, available for aviation and other safety of life applications. But there's no word to that end on http://www.nstb.tc.faa.gov/ as well as...

Is there an on-line directory of TACAN locations? For example, the FAA lists on http://www.faa.gov/atpubs/LID/A_B.htm a TACAN on Bald Mountain Nevada, with designation GBM. However, there is more than one Bald Mountain in Nevada. I'm looking for lon/lat.

Galaxy XV / PRN 135 WAAS arrived this weekend at 133.1W Ranging is now back to the best possible (for GEOs) 7.5 meter UDRE. In its normal operating orbit, it shows up in very high elevation over Hawaii. In this position, PRN 135 provides full Alaska coverage, and with ranging back to 7.5 meter, it...

A few months back, I bought an iPad with the intent of using it in flight for maps, approach plates, and as a supplemental nav. to my GNS 430. I finally got the opportunity to play with it today while doing some hood work to see how well it performs in-flight, and I must say, I am very...

Well JEPP has released a free app for JeppView on the iPad (free if you already have a subscription, of course). There are plenty of reviews out there for different tablets serving as EFB's, but from what I've seen the reviews focus on functions and navigation ease. I have not seen any serious...

Anyone know about the Aeronautical Fixed Telecommunications Network (AFTN) and places that will send / receive a AFTN message for obtaining over flight clearance and providing notifications etc. I am in Portland, OR and would like some place local to do all this I am trying to save a little...

Since PRN133 was set healthy for WAAS corrections, its ranging was kept at NM (Not Monitored) level, preventing its use for safety of life applications, however in the last few days, its ranging improved to UDRE 50 meters, which allows it to contribute for non precision approaches. With this...
