Army Launches 5-Year PNT Technology R&D Program

The Army is kicking off a wide-ranging, five-year research effort to develop new position, navigation and timing (PNT) technologies for battlefield use.

The goal is to overcome technical barriers in a wide range of areas and military officials are offering to fund multiple, and even multi-phase, cost-plus-fixed-fee (CPFF) efforts to do that. The work may range from studies and analysis to development work that results in the production of a prototype-style deliverable or breadboard and/or a demonstration.

Navigating in Space

Figures 1 & 2

Spacecraft in low Earth orbit (LEO), at altitudes below 3,000 kilometers, remain within the main Global Positioning System (GPS) signals’ Earth coverage. Spacecraft employing GPS at these altitudes enjoy signal availability and navigation and timing performance emulating that of terrestrial users.

GLONASS and PNT in Russia

The legal and regulatory framework of the Russian Federation covers not only the GLONASS system, but the country’s overall positioning, navigation and timing (PNT) system as well.

The term PNT is a synonym for navigation activities as defined in the Federal Law on Navigation Activities. The PNT system in the Russian Federation is defined as the combination of administrative and technical means that provide spatial and time data to all user groups, with GLONASS as a key element.

Navipedia — The GNSS Wiki

Javier Ventura-Traveset introduces Navipedia at the Munich Satellite Navigation Summit on March 14, 2012. He is responsible for managing Navipedia’s development as well as GNSS education activities for ESA.

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

In the last 30 years, satellite navigation applications have grown in number and kind, entire new systems have emerged, and existing systems have modernized.
