Real-Time, Precise Data Will Serve Professionals in the Redlands Community

Esri GPS Base Station GISA

The Esri GPS base station, GISA, is mounted to a building in Redlands, California.

Redlands, California—Esri recently installed a GPS base station to assist its GIS developers and to support surveyors, engineers, scientists, and those in public works and public safety in the community surrounding the Esri campus in Redlands, California. The base station, named GISA, has been accepted by the National Geodetic Survey (NGS) and incorporated into the national Continuously Operating Reference Station (CORS) network.

“GPS, originally designed as a US Department of Defense system, has become part of everyday life, with the technology in all types of devices from smartphones to shipping containers,” said Brent Jones, Esri surveying and engineering industry manager. “The Esri GPS base station is a great benefit to the community, as professionals can use it in surveying and positioning to achieve accurate locations in real time.”

NAD83(2011,MA11,PA11) epoch 2010.00 Coordinates

On September 6, 2011, NGS updated the National Spatial Reference System NAD 83 (CORS96, MARP00, PACP00) positions and velocities for all CORS sites, to NAD 83 (2011, MA11, PA11). The NAD 83 (2011) frame, which is relative to the fixed North American plate, is used to define the coordinates for sites located in the CONterminous United States (CONUS), Alaska and US territories in the Caribbean.

OPUS Soon To Have A New Look

February 22, 2011 in Associate Membership, Business, GPS, Land Surveying, News, OPUS, Surveying Software

NGSYesterday, I was using the National Geodetic Survey’s (NGS) Online Positioning User Service (OPUS), where there was a bright green notice at the top of the OPUS page that said, “OPUS will feature a new look-and-feel on or about 03/01/2011″.

In researching this impending change to the look of OPUS, I found the following notice on the NGS Continuously Operating Reference Stations (CORS) newsletter, which says the change is planned for this Thursday, February 24th.

Regardless of which date is correct for this change (or another altogether), I figured I’d give you a heads up.

ON THURSDAY FEBRUARY 24 OPUS WILL HAVE A NEW LOOK

On Thursday OPUS webpages will have a new look, consistent with CORS and NGS web standards.

The NOAA-managed National Spatial Reference System (NSRS), the official U.S. government source for precise latitude, longitude and elevation measurements, provides more than $2.4 billion in potential annual benefits to the U.S. economy, according to a new independent study. Refining and modernizing the system for measuring elevation has the potential to net an additional $522 million in annual economic benefits.

Conducted by Leveson Consulting, Jackson, N.J., the study analyzed the total economic value of all revenue generated from private surveying and mapping as well as from related services in the government and nonprofit sectors. It also assessed the potential cost savings due to improved accuracy of position and elevation data.

Office Of Space Commercialization – Satellite Navigation

November 5, 2008 in Associate Membership, GPS, Land Surveying, Links

Check out the following information from the Office of Space Commercialization, on it’s Satellite Navigation page. There are a lot of good links and information about satellite GPS navigation.


The use of satellites for positioning, navigation, and timing (PNT) has grown dramatically since the U.S. Government authorized civilian access to the Global Positioning System (GPS) in 1983. Thanks to the long-standing U.S. policy of making GPS freely available to the entire world, as well as a track record of highly dependable service, GPS has evolved from a neat gadget into a ubiquitous technology that is now fundamental to the global information infrastructure.

 gps-constellationGPS is a constellation of over 24 U.S. government satellites providing PNT services to an unlimited number of civilian and military users on a continuous, worldwide basis — free of direct user charges. Using the time and position data transmitted by the satellites, a GPS receiver can calculate its location on or above the surface of the Earth within a few meters. When used with an augmentation system, a receiver can attain much higher GPS accuracy — within centimeters, or even millimeters.

Today, GPS technology is in everything from cars and airplanes to Read the rest of this entry →

NGS Announces NEW CORS GOOGLE MAPS

NEW CORS GOOGLE MAPS

The CORS web site ( www.ngs.noaa.gov/CORS/ ) features a new set of
dynamic Google maps to facilitate access to CORS information.
These updated maps were designed and implemented by The CORS Team.
Please view these maps when you get a chance and share with
us (ngs.cors@noaa.gov) your thoughts on their effectiveness.

For a while, the CORS web site will continue to display the static CORS
maps that we have relied upon for nearly a decade.  These static maps,
however, will eventually be discontinued.  The static maps have well
served CORS users, but they are labor intensive to keep up to date.
