FIGURE 1: Proposal to have a single chip GNSS receiver with additional pins to allow for the inclusion of an additional radioQ: What will limit the spread of multi-frequency GNSS receivers into the mass market?
A: To set the scene, we need to define our terms of reference. By multi-frequency we mean receivers that operate with navigation signals in more than just the standard upper L-band from about 1560–1610 MHz where we find GPS L1, Galileo E1, Compass B1, and GLONASS L1. The obvious additional frequency is the lower L-band, from about 1170 to 1300 MHz, where again the same four constellations have signals.

NovAtel has announced support for the BeiDou Navigation Satellite System on its OEM6 family and selected OEMStar GNSS receivers.
The long-anticipated BeiDou Interface Control Document (ICD) release is a
significant milestone that facilitates global acceptance of the Chinese
GNSS system into the growing range of satellite-based positioning
applications, the company says.
Advanced Navigation in collaboration with KVH Industries has announced its new Spatial FOG GNSS/INS, a ruggedized GNSS-aided inertial navigation system and attitude and heading reference system (AHRS).

Conceptual design of ULTRA (ultra low-cost PRS receiver)When European leaders first took up the idea of creating their own GNSS system nearly 20 years ago, they held up the concept of civilian control as a crucial differentiator from existing services operated by national military establishments.
As Galileo nears its operational phase, that principle may manifest itself in a surprising form: the opportunity to offer a range of security-oriented positioning and timing solutions in place of the all-or-nothing alternatives on encrypted services maintained by defense agencies.

This free workshop on GNSS will take place at the Berjaya Times Square Hotel in Kuala Lumpur, Malaysia on December 8, 9 and 10, 2012.
Registration is limited to the first 100 people. The deadline for registration and abstract submission is November 22.
This is the fourth Asia Oceania Regional Workshop on GNSS. It is organized by Multi-GNSS Asia (MGA), whose aim is to promote GNSS interoperability, development, use and applications in the region.

Trimble R10 roverTrimble has introduced its next-generation GNSS surveying solution — the Trimble R10, a small, lightweight receiver that introduces new features and technologies, including Trimble HD-GNSS, Trimble SurePoint, Trimble 360, and Trimble xFill, to provide increased productivity.
Announced at the Intergeo 2012 conference in Hannover, Germany, this week, introduction of the Trimble R10 was accompanied by new versions of its field and office software — Trimble Access 2012.20 and Trimble Business Center 2.80 to extend Trimble’s Connected Site survey solution.
