Adding Location Awareness with GPS Technology

Explore the world of GPS technology and its widespread applications in this 43-minute conference talk from linux.conf.au. Gain insights into the three GPS segments: Control, Space, and User, and understand how they work together to provide precise location and time information. Learn about signal acquisition, tracking, and decoding techniques for civilian Coarse/Acquisition (C/A) satellite signals. Witness a demonstration of decoding Radio-Frequency data, revealing concepts like cold and warm starts, almanacs, and time to first fix. Discover inexpensive GPS hardware options and their integration with devices like Raspberry Pi Zero. Delve into NMEA 0183 sentences, the standard communication protocol for GPS modules, and learn how to parse and process this data effectively. Explore coordinate systems such as LLA and ECEF, and understand how to perform calculations using different Earth models. Finally, examine potential security issues associated with GPS technology, including various attack vectors and privacy concerns in cloud-based services.
