Course 214:

Assisted GPS: Instant GPS and Indoor GPS
 

February 25, 2009

Online registration <<

Instructor Dr. Frank van Diggelen, Broadcom
Objectives An overview of Assisted GPS methods and implementation.

Analysis of coarse-time navigation (“instant GPS”).

Detailed analysis of high-sensitivity receiver design (“indoor GPS”).

An overview of the A-GPS textbook layout and contents to help the student get the most out of their copy.
Prerequisites Familiarity with GPS and basic receiver operation, such as that provided by NavtechGPS Course 111 or Course 122.

Familiarity with engineering terms and data representation.

Course Schedule

8:30 - Introduction, Standard GPS Review
Introduction (why we need A-GPS)
Orbits
Power of received signal
Signal structure
Receiver architecture
A-GPS overview

9:45 - Assistance, the “A” in A-GPS
In-depth analysis of the frequency and code-delay search space
Typical acquisition scheme design for autonomous receivers
Cold, warm & hot starts
Autonomous cold start case study
In-depth analysis of search space reduction with assistance
Typical acquisition scheme design for assisted receivers
Assisted cold start case study

11:00 - Coarse-time navigation “Instant GPS”
NOTE: this hour has a large amount of matrix algebra
Why coarse-time is a problem
“Don’t all receivers solve for time?” (No)
Algebraic nav description (5 states)
Millisecond integer ambiguity resolution
Coarse-time DOP

12:00 - Lunch on your own

1:30 - High sensitivity “Indoor GPS” I
Front End gain
Signal Strength to C/N0 conversion
Coherent integration, Coherent gain
Implementation losses: filtering effect, quantization loss, frequency mismatch, code alignment loss
SNR worksheet

2:45 - High sensitivity “Indoor GPS” II
Integration time vs Correlator size
Longer coherent integration times
Limits to coherent integration: data bit transitions, data bit alignment, frequency error, effect of receiver velocity
I, Q and non-coherent integration
Squaring loss
High sensitivity worksheet

4:00 - High sensitivity “Indoor GPS” III
Generating assistance data
Long term orbits
Frequency bins
PFA (probability of false alarm)
PD (probability of detection)
Sensitivity curves
Reference networks
Long term orbits/ephemeris extension
 

5:00 - Course Ends

Continuing Education
Units
0.6 (6 hours)
Materials You Will Keep • A notebook containing copies of all presentation materials used during the course.

• A copy of the following text:
A-GPS: Assisted GPS, GNSS, and SBAS, Artech House, (available Spring 2009).

• NavtechGPS CD-ROM containing a variety of GNSS references.
