 440A: Indoor GNSS
High-Sensitivity & Wireless Assistance

Register for this tutorial  ~  Back to main tutorials page

This one-day course follows the content of a text-book on Assisted GPS, written by the instructor. All attendees will receive a copy of  Excel worksheets for: GPS Link budget, Front End worksheet, Standard GPS SNR worksheet, and High Sensitivity SNR worksheet. During the class we will work problems in the Excel worksheets, on your laptop (if you have one) and on a projected worksheet that everyone can use.

Motivation & Standard GPS Review

• GPS in mobile phones, PNDs and PDAs.

• E911, location based services.

• How GPS was designed to work.

• GPS signal power, link-budget.

• Standard GPS - why it doesn't work indoors.

Acquisition and Assistance

• Acquisition & assistance overview

• Frequency & code-delay search space

• Industry standards

• MS assisted and MS based GPS

• A-GPS frequency & time assistance

• Frequency/Code search with Assisted GPS

High Sensitivity I

Standard GPS receiver design

• Architecture

• Front-end analysis

• dBm & dB-Hz 

• Correlation, coherent integration & baseband gain

• SNR worksheet

Level:  High-detail course, for those who will implement this new generation of GPS in wireless devices and wireless networks. Knowledge in Courses 110 A&B is assumed.

High Sensitivity II

High-sensitivity receiver design - coherent integration

• Architecture

• Correlator size vs integration time

• Coherent integration

• Implementation losses: IF, quantization, code alignment, frequency mismatch, data bit alignment

• SNR worksheet with long coherent integration

High Sensitivity III

High-sensitivity receiver design - noncoherent integration

• Limit of coherent integration

• I&Q channels and non-coherent integration

• Squaring loss

• Correlator size vs sensitivity

• High-Sensitivity SNR worksheet

• Achievable sensitivity law

Other Sensitivity Considerations

• Hardware and software approaches

• Technology evolution

• Signal strengths in practice, and attenuation through different materials

• Multipath and pure reflections

• Cross-correlation

• Testing the SNR worksheet

• Summary

Level: Knowledge gained in Course 440A is assumed in 440B; it is not recommended that you omit 440A, as the course is taught as a continuum.
