Japan's satellite-based augmentation system has brought meter-level accuracy to that region, which is great news for mapping. But there are even centimeter-level options available that take advantage of Japan's MSAS. Read more»

I covered this subject a while back, but I think it's time to revisit it. Personal navigation devices (PNDs) are still selling like crazy. If you don't have one, someone you know does. Tens of millions of these things are being sold per year. Read more»

There has been a lot of activity on both the civilian and military sides of GPS/GNSS these past few weeks. Instead of a central theme to this newsletter, I'm going to comment on three points of interest: a DoD directive regarding position, navigation, and timing; PRN32; and some new product developments.

With nearly 60 GPS engineers and scientists, the Jet Propulsion Lab (JPL) is one of the biggest GPS R&D centers in the world today.

It appears the US Department of Transportation has bought the Nationwide Differential GPS system (NDGPS) another year. The FY09 Presidential Budget Request was released earlier this week, and it contains a line item in the Research and Innovative Technology Administration (RITA) budget for NDGPS in the amount of $4.6M for operations and maintenance of the current system until October 2009. There is no budget item for the planned build-out of NDGPS. The budget request is subject to approval by Congress, but most likely this will go through. Read more»

One of the hotter topics in the construction industry these days is GPS/GNSS. If any of you attend the World of Concrete exhibition in Las Vegas, you’ll see many examples of how GNSS is being implemented in construction environments. The exhibition is expected to attract more than 1,700 exhibitors and 90,000 attendees this month. I’m sorry I’ll miss it this year, but if you do attend, you’ll find the usual GNSS (and related) suspects exhibiting: Topcon, various Trimble divisions, Leica, Sokkia, Seco Mfg, CST/Berger, Berntsen, etc. Read more»

On the GPS front, I'm going to paraphrase, plagiarize, and otherwise copy from my fellow newsletter editor Don Jewell, who writes the Military & Government PNT newsletter. He spent decades on the inside looking out (think Lt. Col. Jewell) and offers interesting perspectives. Read more»
