SkyTraq Single-Chip OEM GPS

SkyTraq’s Venus634LP

Taiwanese fabless GNSS manufacturer SkyTraq Technology, Inc., has announced a one-square-centimeter GPS OEM receiver, the Venus634LP.

The L1 GPS C/A-code, receiver includes 51 acquisition channels and 14 tracking channels and is also capable of processing satellite-based augmentation system (SBAS) signals. Measuring 10 x 10 x 1.2 millimeters, the Venus634LP integrates LNA, SAW filter, RF front-end, GPS baseband, 0.5ppm TCXO, RTC crystal, LDO regulator, and passive components in an LGA44 package with 0.8 pitch.

Russia Approves CDMA Signals for GLONASS, Discussing Common Signal Design

Nearly 30 years after the first launch of a GLONASS spacecraft, Russia is moving to add code division multiple access (CDMA) signals to the frequency division multiple access (FDMA) format that has set the world’s second-oldest global satellite navigation system apart from GPS and other systems under development.

A February 15, 2008, government decree on new GLONASS requirements calls for open CDMA signals with a binary offset carrier or BOC (2,2) signal structure centered at 1575.42 MHz and a BOC (4,4) signal centered at 1176.45 MHz — essentially corresponding to the center points of GPS signals at the L1 and L5 frequencies and nearby Galileo and Compass signals.

An additional GLONASS FDMA signal will be located at L3 frequencies (1197.648–1212.255 MHz), just below the GPS M-code at L2.

Russia will implement the new signals on the next-generation GLONASS-K satellites, with the first launch currently expected in late 2010 with flight testing the following year.

Satellite Launch Will Aid DoD GNSS Users to Anticipate Space Weather Effects

Communication/Navigation Outage Forecasting System (C/NOFS) satellite, General Dynamics

On Wednesday (April 16), a U.S. Air Force team successfully launched the Communication/Navigation Outage Forecasting System (C/NOFS), an experimental satellite designed to monitor the ionosphere and predict conditions that would disturb radio communications, including GNSS signals.

The satellite was ultimately deployed from a Pegasus rocket following an air launch from a Lockheed L-1011 that had taken off from Kwajalein Atoll in the mid-Pacific Ocean. First transmissions from the spacecraft were acquired shortly after it reached orbit.

NovAtel Offers GL1DE Technology for Precision Ag Guidance

NovAtel Inc. has launched its new GL1DE technology, the latest enhancement to the Calgary, Alberta, Canada–based company’s high-precision OEMV GNSS product line.

GL1DE is a relative pseudorange/delta-phase filter enhancement available in the coompany’s OEMV 3.400 firmware. The new technology is targeted for agricultural guidance applications in which pass-to-pass repeatability and elimination of position “jumps” is critical.

Ivanov GLONASS Flap Obscures Program Reality

Russian Deputy Prime Minister Sergey Ivanov’s criticism of Roscosmos and GLONASS continues to ripple in news columns around the world.
Widely reported in Russian media and picked up and amplified in derivative reports, Ivanov’s complaints focused on GLONASS’s relative inaccuracy, limited coverage, and lack of user equipment.

However, aside from the fact that the person making the remarks was Ivanov — a powerful figure once thought to be in line to succeed Russia’s President Vladimir Putin, none of this is really news. Rather, it seems like another example of the phenomenon that, when people learn of something for the first time, they assume it has just happened.
