Europe is developing Galileo, its
own global satellite navigation and positioning system. The 2
half-day courses (240A-B) inform attendees about the
state-of-the-art design and development of Galileo, outlines the
overall architecture, the frequency and signal plan and presents the
navigation and timing performance. |

Galileo Receiver Design and Performance
Receiver Signal Processing II
• Digital baseband processing
• Acquisition & trade-offs: architectures (serial, parallel, code
matched filter + FFT); detectors (single trial, tong); BOC acquisition
specifics (SSB, DSB, BOC, Bump jumping); trade-off summary
• Final steps in acquisition
• TTFF, TTP
• Tracking
• DLL: loop, discriminators, S-curve, Loop filter, NCO, performance
|
|
|
|
Receiver Signal Processing III
• Narrow correlator (BW vs correlator spacing); carrier aiding; carrier
smoothing; loss of lock; pseudo range
• FLL: loop, discriminators, S-curve, performance; loss of lock
• PLL/Costas: loop, discriminators, S-curve, performance; loss of lock;
loop order Interference
• Multipath
• Iono scintillation
Receiver Navigation & Integrity Processing
• Measurement preprocessing
• PVT
• Integrity

|
Analysis
SubSystem
• GETR lab & GIOVE-A/-B first results
Summary; Q & A session
|
| |
|
Level:
Knowledge of the overall
design of Galileo (Course 240A) is assumed. This session is designed to
be taken in conjunction with 240A, which precedes it, and may not stand
alone comprehensively without that additional material. |
