A. CHANGES TO CORS PRODUCTS AND SERVICES
-----------------------------------------------
Tuesday January 8, 2013
RELEASED REVISED CORS SITE GUIDELINES
Update Guidelines for establishing and operating CORS sites have been released today.
The main change reflects a new minimum spacing requirement of 70 km to nearby CORS. The
rest of the changes are mostly clarifications or corrections to existing requirements.
http://www.ngs.noaa.gov/CORS/Establish_Operate_CORS.shtml
Any questions about these guidelines should be sent to ngs.proposed.cors @noaa.gov
-----------------------------------------------------------------------------------
Tuesday September 6, 2011
RELEASED NEW CORS COORDINATES and ABSOLUTE ANTENNA CALIBRATION PAGES
New CORS coordinates have been released today Tuesday, 6 September 2011. These coordinates
are in:
-IGS08 epoch 2005.00
-NAD 83 (2011,MA11,PA11) epoch 2010.00
-These coordinates are from a stacked solution including data from 1 January 1994 to
16 April 2011.
-60-day and long-term plots are available
-Absolute antenna calibrations have been released in both ANTINFO and ANTEX format
older relative antenna calibration remain available in ANTINFO format
-OPUS-S and OPUS-RS support obtaining solutions in new reference frames as listed
above
-UFCORS provides coordinates in the new frame
A detailed description of the new coordinates with a comparison of results to previous
reference frames, and an FAQ is available:

B. GENERAL NEWS ON ACTIVITIES THAT IMPACT THE CORS PROGRAM
---------------------------------------------------------------------------
Being Awarded US Air Force Contract to Continue GPS Modernization
Boeing Company Press Release
12 February 2013
Boeing will continue modernizing the Global Positioning System (GPS) satellite
constellation for up to five more years, extending the company's role in
the vital military and civilian navigation network.
The U.S. Air Force, which operates the GPS network, recently awarded
Boeing a $51 million, one-year contract with four one-year options. The
contract covers GPS IIF satellite shipment to the launch site in Florida,
pre-launch preparation, post-launch checkout, handover and on-orbit
support.
"The contract provides mission continuity for the Boeing GPS IIF fleet
as we continue to deliver on our commitments," said Craig Cooning, vice
president and general manager of Boeing Space & Intelligence Systems.
"With nine GPS IIFs still awaiting deployment, the contract scope includes
supplying all support needed until the Air Force calls for the vehicles."
Boeing, which has been part of GPS since the network's inception in the 1970s,
hass produced nearly 70 percent of the satellites launched in support of
the GPS constellation.
The company is on contract for 12 GPS IIF satellites, three of which
have been launched into service. The IIFs provide greater navigational
accuracy through advances that include atomic clock technology, a new
civilian L5 signal and an improved military signal.
The next IIF is to launch during the second quarter of this year. Boeing
will complete production of the remaining ones by the end of the year.
"We have the capability to maintain the remaining IIF spacecraft to be
delivered and the flexibility to launch up to three within a single year
if required to sustain the network," said Jan Heide, Boeing GPS IIF
program director.
A unit of The Boeing Company, Boeing Defense, Space & Security is one of
the world's largest defense, space and security businesses specializing
in innovative and capabilities-driven customer solutions, and the world's
largest and most versatile manufacturer of military aircraft. Headquartered
in St. Louis, Boeing Defense, Space & Security is a $33 billion business
with 60,000 employees worldwide.
