The U.S. GPS, and now Global Navigation Satellite Systems (GNSS), is the ubiquitous method for outdoorx000D
positioning and navigation. Hemisphere GNSS develops and sells high-accuracy commercial satellite-basedx000D
positioning / navigation products and services for a wide variety of land and sea applications. One servicex000D
provides GNSS satellite orbit and clock corrections to users via a satellite communications link allowing forx000D
so-called real-time Precise Point Positioning (PPP). The PPP measurement processing technique, with a fewx000D
limitations, provides few centimetre-level positioning and navigation capabilities to a user anywhere on orx000D
above the surface of the Earth, as opposed to the few metre-level for uncorrected GNSS. The company isx000D
interested in improving its real-time so-called PPP GNSS measurement processing user service by applying anx000D
additional ionospheric refraction correction.x000D
The GNSS Laboratory at York University, with its extensive experience in PPP algorithm development andx000D
error modelling, has been requested to support Hemisphere in this complex task. The combined team will: 1)x000D
develop computer code to incorporate corrections from a prototype ionospheric model into the user-positioningx000D
algorithm; 2) alter components of the algorithms, and subsequently the relevant computer code, to make bestx000D
use of these corrections; and 3) test the resulting user positioning solution performance post-modification. Thex000D
two groups will work as one integrated team for this project to enhance the Hemisphere software, so that thex000D
resulting software technology will satisfy the company's requirements and produce a joint research publication.x000D
Hemisphere GNSS has a proven track record as an exporter of high-tech, high-value Canadian products, andx000D
the results of this grant will allow this innovative company to continue to improve its products and grow itsx000D
client base and markets.
