Integer Aperture Estimation

For the complete story, including figures, graphs, and images, please download the PDF of the article, above.

Integer carrier-phase ambiguity resolution is the key to fast and high-precision GNSS positioning and navigation. It is the process of resolving the unknown cycle ambiguities of the carrier-phase data as integers. Once this has been done successfully, the very precise carrier-phase data will act as pseudorange data, thus making very precise positioning and navigation possible.

GPS/ GNSS Community Feels New Telecom Interference Threat from LightSquared

In his State of the Union address on January 25, President Obama held up the Global Positioning System as a prime example of government providing “cutting-edge scientists and inventors with the support that they need” to create world-leading, job-creating innovation.

The following day, the Federal Communications Commission (FCC) International Bureau approved a conditional waiver allowing LightSquared Subsidiary LLC to build tens of thousands of terrestrial transmitters for wireless communications in frequencies on either side of the GPS L1 band.
