Stanford's Wide Area Differential GPS (WADGPS) Laboratory
conducted experimental WAAS Precision Approaches at the
Juneau, Alaska International Airport in August of 1998. The testing included flight trials, collection of WAAS precision
approach performance data, and capture of production in-flight
video footage.
This flight test was sponsored by the Federal Aviation Administration (FAA)
in particular the Satellite Navigation Program Office under
AND-700.
We extend our thanks to them for supporting GPS research here at Stanford.
We would also like to acknowledge the FAA Technical Center's efforts
with regard to maintaining the National Satellite Test Bed (NSTB).
Our flight platform was a Beechcraft Queenair
with navigation, attitude, and tunnel-in-the-sky-over-terrain
display payloads. Each of these payloads was developed as a PhD
research project here in the
GPS Laboratory at
Stanford.
The primary WAAS data link for these flight tests was
the Inmarsat 3 Pacific Ocean Region (POR) geosynchronous satellite
broadcasting Stanford's 250 bps WAAS correction stream. As a secondary
data link the WADGPS Lab had a direct modem link to our portable ground
based VHF transceiver. Follow the links below for more detail on
each project/payload. Checkout our
