The GNSS signal spectrum in neonNavtechGPS, the Washington D.C.-based GNSS technology trainers, will introduce a new advanced receiver course for engineers and designers in their summer seminar series at the Doubletree Hotel in Annapolis, Maryland next July 11-15.
The course is called "Using Advanced GPS/GNSS Signals and Systems." Signal and receiver design expert John Betz, MITRE Corporation, and James Sennott, president of Tracking and Imaging Systems, Inc will teach it.
Continuing a series of acquisitions in recent years, Trimble announced today (April 19, 2011) that the Sunnyvale, California–based company has entered into a definitive agreement to acquire privately held Ashtech S.A.S.
In announcing the its plans, Trimble said that it expects the acquisition of the Carquefou, France, company and its affiliates will expand the U.S. company’s Spectra Precision portfolio of survey solutions and allow the company to better address emerging markets worldwide.

The demand for techniques capable of authenticating the GNSS signals and detecting simulation attacks (spoofing) has increased exponentially in the last years, mainly targeted to financial and safety critical applications.
Associated proposals and developments addressing these issues focused on two different approaches: user segment authentication services that leveraged existing services in order to detect signal spoofing and that integrated signal authentication services into the GNSS system itself.

NavCom Technology’s SF-3040 ReceiverNavCom Technology, Inc., has launched its 66-channel, SF-3040 pole-mount receiver, featuring StarFire/real-time kinematic (RTK) multi-GNSS capabilities and optimized for surveying and mapping applications.
NavCom says its new product provides real-time kinematic (RTK)–level accuracy up to 40 kilometers away from the base station or decimeter-level accuracy anywhere in the world when using the company’s StarFire global satellite-based augmentation system (GSBAS).

Omnistar DGPS world mapTrimble announced on March 16 that it has entered into a definitive agreement to acquire certain assets related to the OmniSTAR GNSS signal corrections business from Fugro N.V.
The acquisition is expected to significantly expand Trimble’s worldwide ability to provide correction services for a broad range of land-based applications in addition to OmniSTAR’s current focus in agriculture. Fugro’s offshore marine business is unaffected.

Q: Does the magnitude of the GNSS receiver clock offset matter?
A: It is well known that GNSS receiver clocks drift relative to the stable atomic time scale that ultimately defines a particular GNSS system in the first place. GNSS receiver manufacturers, however, try to limit the magnitude of the time offset to within some predefined range.
