LV100 Compass
Hemisphere GPS recently introduced two new products: the LV100 GPS Compass Board, an OEM format based on the company’s Crescent Vector technology, and the Air IntelliFlow Dual Rate controller for aerial applications.
GIOVE-A/B Double Difference Ambiguity Measurements, TU DelftResearchers at Delft University of Technology (TU Delft), the Netherlands, succeeded this week in simultaneously tracking the GIOVE-A and GIOVE-B L1 Open Service signals in space, producing the first reported computation of a double-difference carrier phase integer ambiguity resolution on the first two experimental Galileo satellites in orbit.

GPS IIF satellite. Boeing imageThe Boeing Company has announced completion of the latest in a series of environmental tests of the first of 12 GPS IIF satellites, which confirm the mechanical integrity of the spacecraft.
Having apparently overcome technical problems that have delayed the program for several years, the program is now on track to deliver the first satellite to the U.S. Air Force this year, according to the company, with launch currently scheduled for the first half of 2009.

The European Commission (EC) Directorate-General for Energy and Transport (DG-TREN) has issued an invitation to tender (ITT) for an advisor on the European GNSS program.
With a one-year term renewable up to three times, the contract will be designed to provide a pool of experts and organizations for review and counsel on administrative, financial, strategic and technical matters. The services are outlined in two “workpackages,” one for a fixed set of activities and the other for variable services performed according to specific work orders.

SE4150L SiGe Semiconductor, Inc. has released the SE4150L GPS radio receiver featuring dual-antenna input capability for developing GPS products.
Housed in a low profile 4x4millimeter package, the SE4150L RF integrated circuit (RFIC) features a multi-bit output, which improves sensitivity and interference resistance, according to the company. The receiver has a reported system noise figure of 1.0 dB and input third-order intercept performance (IIP3) of better than 0 dBm.

MN5010HSA convergence of a relatively new Singapore-based company, Rockwell semiconductor engineering background, and SiRF Technology’s SiRFstarIII will produce a new family of OEM GPS receivers from Micro Modular Technologies (MMT).
By incorporating the SiRF module, the MN5010HS GPS receiver module represents a departure from MMT’s use of GPS technology from u-Nav Microelectronics (now Atheros Communications GPS business unit). Established in 2005, MMT has also joined the roster of SiRF Technology value added manufacturers (VAMs).

Tanker refueling. Northrop Grumman imageA U.S. Government Accountability Office (GAO) assessment that the U.S. Air Force made “significant errors” in awarding a $35 billion contract for refueling tankers to a consortium including the European Aeronautic Defense and Space Company (EADS) may affect the prospects of foreign participation in development of the Galileo system.

Frequency Electronics, Inc. (FEI) has received an authorization to proceed (ATP) on a new contract to provide master clocks and microwave sources for payloads on the next-generation GPS IIIA satellites. Lockheed Martin Space Systems Company leads a team that will build the IIIA spacecraft under a recently announced Air Force contract.
According to FEI, the value of the contract, when finalized, could exceed $10 million with more than half of the work to be completed over the next 18 months.
