Global Navigation Satellite Systems Engineering, Policy, and Design
The GPS Aided Geo Augmented Navigation (GAGAN) system was developed by the Indian Space Research Organization (ISRO), together with Airports Authority of India (AAI), to deploy and certify an operational satellite-based augmentation system (SBAS). The system’s service area covers the Indian Flight Information Region (FIR), with the capability of expanding to neighboring FIRs.

It will be a busy few weeks for GNSS satellite launches in January and February.
Up next is the Wednesday (January 20, 2016) is a launch of the fifth spacecraft for the Indian Regional Navigation Satellite System (IRNSS). The Indian Space Research Organization plans to complete the IRNSS constellation with two additional launches in February and March.

Late yesterday (December 22, 2015) the Pentagon announced the imminent release of a new solicitation in its two-year search for a contractor to build the next tranche of GPS III satellites.
Air Force Space Command announced on the Federal Business Opportunities (FBO) website that it would publish a request for proposals (RFP) for a phase 1 production readiness feasibility assessment for the new GPS III spacecraft on or around January 8.

The Air Force is weighing its options for a new GPS ground system after a detailed review last week revealed the system would be further delayed — perhaps to as late as 2023.

Equations 1 – 10The constant growth and evolution of the positioning, navigation, and timing (PNT) market generate demands for more and more added-value applications and services relying on GNSS signals, with expectations for improved accuracy and availability. Some services may also rely on added-value content other than navigation messages, for example, higher data volume with less latency, such as the data carried by satellite-based augmentation system (SBAS) services and the Galileo Commercial Service.

Speakers at the low-in-profile but high-in-content International Association of Institutes of Navigation (IAIN) conference in Prague this year threw into stark relief some of the big GNSS programs and even bigger GNSS questions.

Sergey RevnivykhSpeakers at the recent International Association of Institutes of Navigation (IAIN) conference in Prague threw into stark relief some of the big GNSS programs and even bigger GNSS questions.
Prof.-Dr. Günter Hein, former head of the European Space Agency (ESA) EGNOS and GNSS Evolution Program Department and Emeritus of Excellence at University FAF Munich, delivered a fact-filled and level-headed presentation on the status of Galileo, the European Union’s civil-owned and non-military GNSS, with slides and information provided by ESA.
The United Launch Alliance (ULA) send-off of the 12th GPS Block IIF satellite scheduled for next February 3 may turn out to be the last GPS launch for the Boeing/Lockheed Martin joint venture — at least for a while. ULA did not submit a bid to launch the next generation of GPS satellites (GPS III).

The new GPS ground control system’s cascading delays and ballooning budget have the Department of Defense (DoD) looking at other options, including shifting to an enhanced version of an existing control system, Inside GNSS has learned.
The Next Generation Operational Control System (OCX), which already has more than doubled in cost, will be the focus of a second “Deep Dive” review before the DOD’s top acquisition official on December 4.

Some 15 years ago, Bob Denaro predicted the disappearance of GPS into its various applications.
That prediction by the former Trimble/Motorola/Navteq executive has largely been validated. Although GPS has survived in the popular consciousness as a global brand, connoting an almost magical source of location and tracking, general recognition and understanding of GNSS as a core technology within products and services has, indeed, remained murky.

The U.S. Air Force GPS Directorate released a final request for proposal (RFP) for Global Positioning System (GPS) III Launch Services today (September 30, 2015).
Launch services include launch vehicle production, mission integration, and launch operations for a GPS III mission scheduled to launch in 2018. Proposals are due back to the Air Force no later than Nov. 16 in accordance with the solicitation instructions.
