Trimble Announces New Precision Products, RolleiMetric Acquisition, and Saab JV


Trimble
has announced its new GNSS reference receiver — the Trimble NetR8 — for precise scientific and network infrastructure applications. The NetR8 reference receiver has 76 channels and supports GPS L1, L2, L2C and L5 signals as well as GLONASS L1/L2 signals.

Four additional channels are dedicated to tracking space-based augmentation systems
(SBAS), including Wide Area Augmentation System (WAAS) in North
America, European Geostationary Navigation Overlay System (EGNOS) in
Europe, Multi-functional Satellite Augmentation System (MSAS) in Japan,
Omnistar services and others.

GNSS Album: Images and Spectral Signatures of the New GNSS Signals

Until now, civilian global satellite navigation systems (GNSS) receivers have had essentially only one signal, the GPS L1 C/A-code, reliably available for navigation. However, in the coming years, many more operational GNSS signals, systems, and frequencies will become available to civilian users.

GLONASS–A New Look for the 21st Century

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 GNSS apart from GPS and other systems under development.

Applanix Launches POS AV with Integrated Trimble GNSS, Upgraded DSS RapidOrtho

Applanix has announced the availability of a high altitude tactical mapping option for its DSS RapidOrtho system as well as the integration of the Trimble BD960 GNSS receiver module for its POS AV airborne position and orientation system.

With the GNSS module, POS AV products now support GPS L1/L2 and GLONASS L1/L2 processing, both in real-time and post-mission. The BD960 will also be able to receive and process the next-generation GPS L2C and L5 signals.

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.

IfEN Receives ESA EGNOS-Related Contract

The European Space Agency (ESA) has awarded a contract to IfEN GmbH to develop a “New Generation” receiver breadboard for use at the European Geostationary Navigation Overlay Service (EGNOS) Ranging and Integrity Monitoring Stations (RIMS).

The RIMS New Generation breadboard will be capable of receiving the new L2C and L5 signals, the Galileo E1, E5ab, and E6 signals and the GLONASS L1 signal in addition to GPS L1 and L2P signals.

Russia Dwells on Glonass Future

Despite a recent round of criticism from high-ranking officials, Russia’s GLONASS system is pushing ahead with a six-satellite launch schedule in 2008 and the prospect of adding code division multiple access (CDMA) signals to future broadcasts.
