Boeing Will Build GPS IIF Satellites on New ‘Pulse’ Line

The Boeing Company will use its new “pulse line” process for assembling satellites to build GPS Block IIF satellites for the U.S. Air Force.

Constructed at the company’s facility in El Segundo, California, the new process is expected to shorten the time needed to build a space vehicle and will eventually be implemented on all Boeing satellite production lines.

For the Block IIFs the new process will reduce the travel distance of a space vehicle from 12,000 feet to 10,000 feet, according to John Duddy, director of GPS programs for Boeing.

Okay, they’re really serious about open source.

Mobile device manufacturer Openmoko has announced that it will publish the schematics for the company’s Neo 1973 and Neo FreeRunner mobile phones, further opening its mobile platform to the development community.

u-blox AG, Switzerland, maker of the GPS chip — the u- ANTARIS 4 ATR0635 — used in the Neo FreeRunner, endorsed Openmokos publishing the complete schematics for the GPS chip in the Neo FreeRunner phones.

GIOVE-B Signal Observations Confirm MBOC’s Multipath Advantage

Standard deviation of code multipath for Galileo signals transmitted by GIOVE-B. The two thicker lines show the L1BC modulations: BOC(1,1), light green, and CBOC (dark green).

Initial results from observations of the Galileo GIOVE-B satellite conducted by researchers at the European Space Agency (ESA) and Septentrio Satellite Navigation indicate that the multiplex binary offset carrier (MBOC) modulation outperforms the BOC(1,1) modulation on the L1 (data + pilot channels) frequency in mitigating the effects of multipath or reflected signals.

Air Force Hopes for November, December Launches of Final GPS IIR-Ms

UPDATED SEPTEMBER 10 2008: With replacement parts currently being manufactured for faulty components that have delayed launch plans, Air Force GPS program managers hope to get the final two modernized Block IIR satellites on orbit by the end of the year.

A tentative launch date of November 7 has been targeted for the Block IIR-20(M), which will carry a payload that includes an experimental L5 signal. If all goes well, the final IIR launch would take place by December 31.

NXP/STMicroelectronics JV Launches

ST-NXP Wireless, a new company bringing together key wireless operations of STMicroelectronics and NXP, will begin operations August 2 following completion of a deal announced earlier this year.

Owning thousands of communication and multimedia patents, the new joint venture will bring key technologies for UMTS (Universal Mobile Telecommunication System) and for the emerging TD-SCDMA standard, as well as other cellular, multimedia and connectivity capabilities — including WiFi, Bluetooth, GPS, FM radio, USB, and UWB (ultra-wideband).

The 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.

SiGe Launches GPS Radio with Dual-Antenna Capability

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.

Micro-Modular Technolgies Joins SiRF Club

Micro-Modular Technolgies Joins SiRF Club

MN5010HS

A 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).

Frequency Electronics Gains GPS IIIA Clock Contract

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.
