A Glowing Report Doth Not a Golden Future Make

November 27, 2013By

The tech press and broad public media have both made much ado about a November market report from the European GNSS Agency (GSA). Most accounts have focused on a GSA prediction of an installed base of 7 billion GNSS-enabled devices worldwide by 2022, and nearly every account has replicated the GSA math to trumpet “almost one for every person on... read more

New GLONASS Navigation Message Proposed

September 30, 2013By

Russian scientists and engineers are at work on a new code-division multiple-access signal format to be broadcast on a new GLONASS L3 signal. Taking an approach similar to that implemented on the newly designed GPS L5 signal, this will, once implemented across the constellation by new satellite launches, facilitate interoperability with and even eventually interchangeability among other GNSS signals, including... read more

The System: Compass Signal ICD this Month

October 1, 2011By

The long-awaited signal interface control document (ICD) for China’s growing GNSS will appear this month, according to representatives of the system who spoke in a “Compass: Progress, Status, and Future Outlook” workshop as part of ION GNSS and the CGSIC meetings in Portland in September. The ICD has been rumored to be available previously to receiver manufacturers within China, creating... read more

Compass ICD in October; Harmonizing GNSS

September 29, 2011By

China's GNSS, Compass or Beidou, intends to publish its signal interface control document (ICD) in October. Representatives of the system made an unprecedented showing at ION GNSS in Portland, and referred frankly to "internal deliberations" that may be at the root of much of the public uncertainty about the system's planned structure and timeline. Meanwhile, representatives of other navigation satellite systems also delivered updates on their status and plans. Everyone is concerned about LightSquared interference, but everyone continues to move forward. This month's column is a two-parter: a guest appearance by Len Jacobson, editorial advisory board member for GPS World magazine and president of Global Systems and Marketing Inc. Len writes on the "Harmonizing GNSS" aspect, the briefings by all systems and their efforts to achieve compatibility and interoperability. Then I'll return with an account of the Compass panel that formed part of the CGSIC meeting immediately preceeding ION. read more

The System: Second Report by LightSquared/GPS Technical Working Group Maps Terrain, Does Not Yet Explore

May 1, 2011By

Plus: GLONASS CDMA Tracked, Third Beidou-2 Launched The second report from non‐governmental members of the LightSquared/GPS Technical Working Group (TWG) was filed with the Federal Communications Commission (FCC) on April 15. For those anxious to see actual results of interference/desensitization of GPS receivers by the proposed LightSquared terrestrial signal — or, conversely, absence of said results — the report does not contain... read more
