Swedish technology group Hexagon AB, which acquired Leica Geosystems in 2005, launched its tender offer to acquire all the issued and outstanding common shares of NovAtel Inc., a Calgary, Alberta, Canada–based developer and manufacturer of OEM GNSS and related products, at a price per share of US$50 cash.

The stunning sequence of multi-billion-dollar buyout offers for the two leading navigable map data providers TeleAtlas and NAVTEQ — by TomTom and Nokia, respectively — raises issues not only of access to critical intellectual property (IP) and a long-delayed explosion of location-based services (LBS) but may also determine the outcome of the long-debated platform of choice for GNSS-enriched consumer applications.

Boeing technicians and first Block IIF satelliteThe Boeing Company has successfully assembled and integrated all flight hardware onto the first GPS Block IIF (follow-on generation) satellite. Launch is now scheduled for the second half of 2008.
GPS llF spacecraft will bring new capabilities to the GPS constellation, such as a new encrypted military code, a new civil signal, crosslink enhancements, increased signal power, and longer design life. Boeing is building 12 GPS Block IIF satellites under contract from the GPS Wing at the Space and Missile Systems Center at Los Angeles Air Force Base.

Trimble has introduced a new, real-time kinematic (RTK) compact GNSS card — the Trimble BD960 — for high-precision guidance and control applications, such as unmanned vehicles and port and terminal equipment automation.

Thales Alenia Space Italia (TAS-I) has awarded NovAtel Inc. a €440,000 milestone award for continued development of the Galileo ground reception Chain (GRC) reference receiver. Although the incremental size of the award is modest, the agreement provides for confirmed, longer-term funding of a two-year-old contract valued at €6.3M (US$8.6 million).

GLONASS has gotten “preliminary approval” to add code division multiple access (CDMA) signals to future satellites.
Since its initiation in the early 1980s, the Russian GNSS system has employed frequency division multiple access (FDMA) techniques in which the same code is used for the signals broadcast by the system, with individual spacecraft being distinguished from one another by a specific frequency allocation. Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.

Selective Availability (SA), the contentious issue of degrading the open GPS civil to advantage military signals, is going away for good under the terms of a presidential decision announced September 18.

NovAtel Inc. has acquired privately held antenna manufacturer Antcom Corporation (Antcom) for $5 million in cash and an additional $1 million in cash subject to Antcom’s achievement of certain financial targets for the calendar year ended December 31, 2007.

On September 14, Air Force crews at Schriever AFB, Colorado, completed the initial phase of an $800 million upgrade to the GPS operational control segment.
Operators in the 2nd Space Operations Squadron (2SOPS) of the USAF 50th Space Wing migrated control of the GPS satellite constellation and ground monitoring facilities from a 1970s-era mainframe computer to a distributed IT infrastructure with advanced automated features. The 50th Space Wing, through the 2nd SOPS, performs the satellite command and control mission for the Global Positioning System.

The United States and the European Union (EU) have agreed to use the multiplexed binary offset carrier (MBOC) for a common GPS-Galileo signal for civilian use. In the future, this will enable combined GNSS receivers to track the GPS and Galileo signals with higher accuracy, even in challenging environments that include multipath, noise, and interference.
These signals will be implemented on the Galileo Open Service and the GPS IIIA new L1 civil signal known as L1C.

The September 6 crash of a Russian Proton-M rocket carrying a Japanese telecommunications satellite (JCSAT 11) has injected an element of uncertainty into plans for completing the GLONASS constellation.
Russia’s Baikonur cosmodrome automatically suspended all Proton rocket flights, pending an investigation, after the failure of the rocket, which crashed in the steppes of Kazakhstan just over two minutes after lift-off. Russia rents the space facility from Kazakhstan, a former republic in the USSR.

After several false starts in the previous months and a multi-year delay in the overall GPS III architecture development, the GPS Wing (formerly the GPS Joint Program Office) announced on July 12 the release of a request for proposal for the development and production of the GPS Block IIIA satellites.
