Trimble has released the SX10 scanning total station that merges high-speed 3D scanning, imaging technology, and total station measurements for surveyors, the company said.
"This is the top one or two [products] we have launched in the 20 years I’ve been here," said Ron Bisio, Trimble geospatial division vice president, at a media day in Westminster, Colorado, October 5.

EquationsThe Galileo E6 signal is centered at 1278.75 MHz, and comprises three signals: an authorized signal (E6A, the publicly regulated service, PRS plus two civilian signals), a data component (E6B), and a pilot component (E6C). Both E6B and C are modulated using binary-phase shift keying (BPSK) code division multiple access (CDMA) memory codes, having lengths of 5,115 chips and chipping rates of 5.115 Mcps.

Eclipse P326Hemisphere GNSS has introduced two new OEM boards, the Eclipse P326 and P327, designed for machine control, land or marine survey, and agriculture applications. The boards support GPS, GLONASS, BeiDou, Galileo, and Japan’s QZSS (Quasi-Zenith Satellite System).
The boards are the first within the Eclipse product line to have refreshed low-power capability, reduced size, cost, and weight, the company said. P326 and P327 offer centimeter-level accuracy in either single- or multi-frequencies, using signals from multiple GNSS constellations. and Atlas-capable modes.

In February 2011, Russia launched the first satellite of the GLONASS-K1 series, i.e., SVN (space vehicle number) 801 (R26), which in addition to the legacy frequency division multiple access (FDMA) signals, for the first time was enabled to transmit code division multiple access (CDMA) signals on the GLONASS L3 frequency (1202.025 MHz). Later in 2014, the GLONASS program added SVNs 802 (R17) of series K1 and 755 (R21) of series M, and in 2016, SVN 751 of series M, with the capability of transmitting CDMA L3 signals to the constellation.

Graphic Depicting NDGPS Coverage After Site ReductionsThe U.S. Coast Guard, the U.S. Army Corps of Engineers (USACE), and the Department of Transportation (DoT) released a Federal Register notice today (July 5, 2016) announcing a reduction of the Nationwide Differential Global Positioning System (NDGPS).
The planned reduction calls for the shutdown and decommissioning of 37 DGPS sites, leaving 46 operational sites available to users in coastal areas. Termination of the NDGPS broadcasts is scheduled to occur on August 5, 2016.

u-blox has released a firmware upgrade for its NEO-M8P that now supports China’s BeiDou GNSS system in addition to GPS and GLONASS.
Capable of real-time kinematic (RTK) positioning, the new NEO-M8P firmware now offers eight-hertz RTK update rates for GPS.
NovAtel Inc. has submitted comments to the Federal Communications Commission (FCC) regarding Ligado Networks LLC’s (formerly New LightSquared LLC) License Modification Applications in which the company raises deep concerns about the testing methodology used and conclusions presented by Ligado regarding the impact of their proposed usage of L-band frequencies for a terrestrial wireless network.

GNSS signals are vulnerable to interference due to being extremely weak when received on Earth’s surface. Therefore, even a low-power interference signal can easily disrupt the operation of commercial GNSS receivers within a range of several kilometers.
